Month: October 2019

Joy Loving prepared this week’s edition, with assistance from Les Grady.

Politics and Policy

The Washington Post’s (WaPo) Editorial Board believes that “There’s an effective and progressive solution for climate change. [They ask] Why won’t Democrats embrace it?”  The authors argue that “The science does not change because politicians deny that humans are warming the planet. Likewise the economics do not change because politicians find them ideologically or politically inconvenient.”  The Hill reports that “Trump prepares to formally withdraw US from Paris Climate Accord”. Vice notes that “This Alaskan Forest Eats a Ton of Carbon. The Trump Administration Wants to Let Loggers Cut It Down.

It’s as big as the entire state of West Virginia.”

The Hill prints a joint op-ed by Senators Chris Coons (D-Del.) and Mike Braun (R-Ind.):  “New Senate caucus will seek bipartisan solutions to address the climate challenge”.  Grist asks “Congress is losing a major Republican climate hawk. What now?”  Francis “Rooney is the current co-chair of the Climate Solutions Caucus, a bipartisan group in the House of Representatives whose main objectives are to educate members of Congress about climate change and to push for climate legislation….”  Rooney just announced he’s leaving the House of Representatives.  A CCL spokesperson “cited recent polling that shows growing support for carbon taxes and a Green New Deal among young Republicans. And he said that Republicans from districts that have been touched by extreme weather and other climate-tinged events are wising up to the fact that voters support climate action.”

Canadian Broadcasting Company (CBC) says that the recent election in our northern neighbor yielded a winner beyond the politicians:  “The big election winner? The carbon tax”.  Jules Kortenhorst of Rocky Mountain Institute (RMI) believes “The next US administration has the chance to strike the greatest climate bargain of all time. For less than $3/ton of CO2 abated, the next US government could economically retire the nation’s coal plants and buy back the planet’s future – all while saving US consumers billions.”  In an opinion piece for Utility Dive, Jacob Susman, a partner at Mission Driven Capital Partners, argues that “We’re already paying a carbon price — let’s invoice those responsible and collect the dividends instead”.

Politico reports that “USDA inspector general launches climate change investigation”.  At issue is whether “the department has been routinely burying its work on climate change, even as farmers and ranchers are increasingly dealing with its harmful effects.”  Grist has a story about fired members of the EPA’s Clean Air Scientific Advisory Committee who nonetheless “reconvened to review the latest science and offer recommendations for new air quality regulations… [and later] issued a letter warning that current regulatory limits pose a threat to public health and urging stricter standards to limit particulate pollution, which has been linked to increased risk of a host of heart and respiratory diseases.”  This item in the Allegheny Front says “Pennsylvanians Tell EPA, We Need More Controls on Methane, Not Less”.

The Atlantic has a story about ocean acidification:  “The Worst Day in Earth’s History Contains an Ominous Warning.  One of the planet’s most dramatic extinctions was caused in part by ocean acidification, which has become a problem in our own era.”  The story explores the similarities between the massive extinction that happened after the huge asteroid slammed into Earth, particularly the effects on oceans.  Ocean acidification played an important role in three mass extinctions, suggesting that we should be paying more attention to the acidification going on now.

Climate and Climate Science

The Associated Press reports that the “South Pole’s ozone hole shrinks to smallest since discovery”. The shrinkage “is more due to freakish Antarctic weather than efforts to cut down on pollution,” according to NASA.  WaPo also covered this story.

The Guardian recently pledged to “give the climate crisis the attention it demands.”  Here are 3 recent examples of its coverage:

1. “Renewable energy to expand by 50% in next five years – report”.  “The International Energy Agency (IEA) found that solar, wind and hydropower projects are rolling out at their fastest rate in four years.”
2. “‘Racism dictates who gets dumped on’: how environmental injustice divides the world”.  The paper’s “new environmental justice reporter, Nina Lakhani, asked five luminaries of the movement to explain “environmental justice”…. They reveal why, alongside global heating and the extinction crisis, it is one of the most pressing issues of our time.”
3. Alex Preston reviews Jonathan Safran Foer’s new book We Are the Weather: Saving the Planet Begins at Breakfast by Jonathan Safran Foer review – a life-changing book.

This somewhat wonky but interesting reporting by ScienMag on a University of California Irvine study sheds light on how “Plant physiology will be major contributor to future river flooding”.  As if “precipitation anomalies caused by atmospheric warming” isn’t enough of a problem, because “[p]lants get more water-efficient and leak less underground soil moisture out through their pores in a carbon-rich atmosphere,”… there is … more soil moisture stored up underground, so … climate models predict rainfall events will saturate the ground and more rain will run off into rivers.”  A new study in The Proceedings of the National Academy of Sciences (PNAS) has found that climate change is making stronger El Niños, which change weather worldwide and heat up the planet.

Anchorage (AK) Daily News describes how “A Western Alaska village, long threatened by erosion and flooding, begins to relocate”.  National Geographic also covers this story.  The CBC says that “Climate change has turned permafrost into a carbon emitter [and] Social Sharing [and] Tundra plants can’t absorb enough carbon in summer to make up for carbon released in winter”. A paper that was published Monday in Nature Climate Change reported that the amount of CO₂ released as a result of thawing permafrost was almost twice as much as that taken up by plant growth, making the Arctic a net emitter of CO₂.  Deutsche Welle (DW) also covers the effects of the climate crisis on indigenous Alaskan peoples in “Alaska: Climate change threatens indigenous traditions”. 

Reuters reports that “Climate change hampers progress on fighting epidemics: Global Fund”.  Grist reports on a “New study [that] pinpoints the places most at risk on a warming planet”.  “As many as five billion people will face hunger and a lack of clean water by 2050 as the warming climate disrupts pollination, freshwater, and coastal habitats…. People living in South Asia and Africa will bear the worst of it.”  WaPo interviews Al Gore about his latest climate-related presentation, this one a stark warning “of a looming food crisis caused by climate change”.  The Intercept interviews Bill McKibben about his new book, Falter: Has the Human Game Begun to Play Itself Out?  Ozy has a story about Germany’s Minister for Food, Agriculture, and Consumer Protection who “Believes Trees Will Save Germany — If She Can Save the Trees”. Michigan Radio (NPR station) has a story headlined:  “Without widespread cultural change, the climate crisis won’t be solved, says UM expert”. The New York Times publishes an opinion piece by Naomi Orestes and Nicholas Stern titled “Climate Change Will Cost Us Even More Than We Think”.  Bloomberg also covered this story.

Energy

In a recent Executive Order, “Governor Ralph Northam Signs Executive Order to Expand Access to Renewable Energy, Support Clean Energy Jobs of the Future”.  The Richmond Times Dispatch headlined the story “State to buy energy from solar, wind projects to power government”.  And so did the Roanoke Times with this item:  “Plans for wind farm in Botetourt County move forward”.  Yale Environment 360 has this related item:  “Small Adjustments to Wind Turbines Can Reduce Impacts on Birds, New Study Finds”.  A recent study in the journal Energy Science found that changes to wind turbine design, such as making them taller with shorter blades, could decrease bird mortality.  Utility Dive says “Virginia signs largest state renewable energy contract in US with 420 MW Dominion deal”.  The arrangement “aims to help the state meet new clean energy goals.  Combined with previously announced solar projects, electricity produced by the new wind and solar resources will help meet the equivalent of 45% of the state government’s annual energy use.”

Nearly a third of the Earth’s electricity will come from renewables by 2024, according to the International Energy Agency.  However, they warned that the expansion will still be “well short” of what’s required to meet aggressive goals aimed at fighting climate change.  A bipartisan group of 231 mayors sent a letter to Congress urging them to pass the Renewable Energy Extension Act (HR 3961/S. 2289), a five-year extension of the solar Investment Tax Credit.  Here’s a utility rate request that’s pretty unusual:  Camden News reports that “South Arkansas electric utility seeks rate reduction”.  Why?  “Ouachita Electric Cooperative is preparing to ask state regulators to lower rates for its 7,000 members in five south Arkansas counties. The decrease is fueled by advances in solar power and other efficiencies the utility has created.”  More good news from Ensia:  “New report: Efficiency can cut U.S. energy use and greenhouse gas emissions in half by 2050”.

The Roanoke Times says that “Work on Mountain Valley Pipeline is winding down” but not because of the coming winter.  “Mountain Valley has lost three sets of key permits — all suspended because of the pipeline’s impact on the environment — that have fallen like slow-motion dominoes for a project that was supposed to be done by now.”  In another recent piece, the Times reports “Another delay, cost increase for Mountain Valley Pipeline”.  The Virginia Mercury has this recent headline, echoing the same stories:  “Mountain Valley Pipeline’s cost rises to $5.5 billion, completion pushed to 2020”.  The Post and Courier asks:  “Will SC need gas pipeline like it needed abandoned coal, nuclear plants?”  The piece questions Dominion Energy’s CEO’s wish to “to bring the [Atlantic Coast Pipeline into South Carolina]… if the demand is there”, concluding “It might turn out that we really do need additional natural gas capacity. Or it might turn out that we need another natural-gas pipeline about as much as we needed the coal plant and the nuclear reactors.”

Maritime transport is a large contributor to CO₂ emissions.  This Guardian article reports in “Winds of change: the sailing ships cleaning up sea transport” that “Clean transport is the missing link, as many so-called sustainable or ethical goods are currently carried on ships that pollute the air and sea,” and that several shipping companies are increasing their transport of “sail cargo”.  Grist tells the story of “DREAMBOATS [and how] Space-age sails, bionic hulls, clean fuels drawn from the oceans themselves — the shipping industry is poised for transformation … if the stars align.”

The cost gap between electric and gas model cars is beginning to shrink, according to Rachelle Petusky, the manager of research and market intelligence for Cox Automotive Mobility.  And that shift is going to accelerate.

The Guardian has this opinion piece about New York State’s lawsuit against ExxonMobil.  Discussing how mis- and dis-information campaigns have slowed the public’s grasp about the dangers of carbon pollution, the authors reference their report, “America Misled: How the Fossil Fuel Industry Deliberately Misled Americans About Climate Change”.  They conclude:  “Exposing and explaining the techniques of denial are crucial steps in neutralizing disinformation… from any source. Once people know the ways they can be deceived, disinformation no longer has power over them…. But it’s not enough to offer information – we also have to expose disinformation, so that people understand what we have been up against.” Inside Climate News also writes about this trial and about “Former Exxon Scientists Tell[ing] Congress of Oil Giant’s Climate Research Before Exxon Turned to Denial”. UPI reports on another lawsuit on the same issue: “Supreme Court declines to issue stay in Baltimore suit against oil companies”.  Inside Climate News says Massachusetts has also sued ExxonMobil “Over Climate Change, Accusing the Oil Giant of Fraud”.  Politico has a story explaining how “Researchers can now link weather events to emissions – and to the companies responsible. A string of lawsuits is about to give “attribution science” a real-life test.”

Weather Internal (WI) reports that “Government Loophole Gave Oil Companies an $18 Billion Windfall”.  Excerpting from a New York Times story, WI quoted:  “The United States government has lost billions of dollars of oil and gas revenue to fossil-fuel companies because of a loophole in a decades-old law, a federal watchdog agency said…, offering the first detailed accounting of the consequences of a misstep by lawmakers that is expected to continue costing taxpayers for decades to come.”

Potpourri

NBC News has a story (and video) about a Columbia University light exhibit that lets “visitors … imagine what life would be like under 10 feet of water as humanity is confronted by the effects of climate change.”  Thompson Reuters has a somewhat related story:  “As climate impacts hit, cities are still struggling to prepare, researchers warn”.

From ted.com comes this 6:25 minute video about one marine biologist’s love of parrotfish, their unusual lifecycle and behaviors, and the news that humans have overfished them and that their habitat—the coral reefs—may not be around in 30 years unless we do something to stop their destruction.

BBC News has pictures that illustrate the dramatic loss of glacier ice in Iceland since the 1980s.  CNN reports on the wildfires raging in California.

On November 7, the “Byron Allen’s Weather Channel to host Special on Climate Change’s Impact on Black Communities With Presidential Candidates”.  The Weather Channel “will air 2020: Race to Save the Planet, a one-hour, primetime special featuring conversations with the network’s meteorologists and nine presidential candidates on climate change and produced in partnership with The Climate Desk, a media consortium.”

NOTE:  Solar United Neighbors/VA announces its 2019 Solar Congress, to be held in Williamsburg on November 16.  The list of topics includes basic solar information, electric vehicles and solar, advancing rooftop solar policy in VA, organizing to advance solar on the local level, battery storage and solar, equity in solar, organizing for solar in rural electric cooperatives, solar for schools/churches/non-profits, solar workforce development, and the business case for solar.  To learn more and register, visit this link.

Politics and Policy

President Donald Trump confirmed that U.S. Energy Secretary Rick Perry will step down from his Cabinet post at the end of the year.  Trump also announced that he would nominate Deputy Energy Secretary Dan Brouillette to succeed Perry.  Following on the heels of a federal appeals court ruling that stayed a key permit for the Mountain Valley Pipeline, the Federal Energy Regulatory Commission ordered that all work on the pipeline stop, except for stabilization and restoration activities.

The Federal Reserve Bank of San Francisco published a report regarding the financial risk of climate change to low- and moderate-income communities.  The risk is dire, but the report proposes actions that could alter the behavior of financial institutions and local governments, pushing them to better prepare for climate change.  Unlike most Republican-led state governments, Florida has a chief resilience officer, whose job it is to prepare the state for the types of risk considered in the Fed report.  Climate risk has a big impact on the insurance industry, which raises the question of whether it can survive.  At WBUR, Robin Young discussed this question with The Economist finance correspondent Matthieu Favas.  Mark Carney, the governor of the Bank of England, told The Guardian, “Companies and industries that are not moving towards zero-carbon emissions will be punished by investors and go bankrupt…”

Climate change will not be on the agenda at next year’s Group of Seven (G-7) summit hosted by the U.S. at Trump National Doral near Miami.  John D. Macomber of the Harvard Business School examined the options for building (or rebuilding) in an age of climate change.  An editorial in The Economist addressed how national carbon-cutting goals should be expressed.  One example was the necessity to include imbedded-carbon from imports in the calculations.  Forty-five percent of carbon emissions come from making things.  A new report argues that the best way to address them is to shift to a circular economy.  At Yale Environment 360, Fen Montaigne interviewed William Moomaw of Tuft’s University who is a proponent of “proforestation”, leaving older and middle-aged forests intact because of their superior carbon-sequestration abilities.

Umair Irfan and David Roberts at Vox asked the Democratic presidential candidates six climate-related questions that haven’t been asked at the debates.  Nine responded.  The answers can be found here.  If you don’t have time to read their responses, Grist had the highpoints.  Climate change is often listed as a driver of conflict, particularly in regions of the world where water is scarce.  But, is it?  John Vidal addressed that question in Ensia, ending with a quote from a recent paper in Nature: “Across the experts, best estimates are that 3–20% of conflict risk over the past century has been influenced by climate variability or change.”  However, Vidal said, “… they also wrote that the risk of conflict is likely to increase as climate change intensifies.”

Climate and Climate Science

Carbon Brief has published its third quarterly “State of the Climate” report for this year.  So far, it looks like 2019 will be the second warmest year on record, even though there was no El Niño.  Switzerland’s glaciers have lost a tenth of their volume in the past five years alone — a rate of melting that is unprecedented in more than a century of observations.  Even before the impacts of 2019 had occurred, 92% of Greenlanders thought that climate change is happening, but only 52% thought it is human-caused.  National Geographic had an interesting retrospective piece about how scientists discovered that the ice dams that hold back Greenland’s glaciers are being melted from the bottom by warm sea water.

A study published in the Proceedings of The Royal Society B found that forest birds take their cue for nesting from nighttime temperatures in the spring.  Consequently, as climate change causes temperatures to rise, the breeding patterns of birds are being altered.  A study published in the journal Nature found that toxic algal blooms are increasing across the world as temperatures rise.  The study was based on 30 years of NASA data.  Driven in part by climate change, species turnover has increased in many ecosystems as species better adapted to current conditions displace traditional ones.

Qatar has already seen average temperatures rise more than 2°C above preindustrial times, which means it is experiencing some very hot temperatures.  In addition, Qatar is very humid, because of its location in the warm Persian Gulf.  Consequently, Qatar is air conditioning the outdoors, which is one reason it has the highest per capita greenhouse gas emission rate in the world.  Far away from Qatar, in South America, the Xingu River is one of the Amazon River’s largest tributaries, but more than a third of its drainage basin, a region bigger than New York State, is now deforested.  This makes the basin a perfect laboratory in which to study the impact of deforestation on climate and the remaining rainforest.

Two new papers, one in Nature Communications and the other in the Proceedings of the National Academy of Sciences, examined how two important diseases will spread in response to global warming and land use.  The first study looked at Ebola and concluded that as temperatures warm, Ebola will move to other parts of Africa as the bats that harbor the virus move.  The second looked at malaria, finding that deforestation significantly increases its transmission. 

According to this year’s global hunger index, climate change is driving alarming levels of hunger in the world, undermining food security in the world’s most vulnerable regions.  In the U.S., farmers are increasingly experiencing the impacts of severe weather, yet the Department of Agriculture spends just 0.3% of its $144 billion budget helping them adapt to climate change.

Energy

This week’s “Climate Fwd: Newsletter” from The New York Times had an interesting article about heat pumps and the energy that they save.  One item that the author didn’t mention is that the cleaner your electricity gets, the cleaner the heat pump gets, as opposed to a furnace, which will always emit greenhouse gases.

According to the NYT, some of the major oil and gas “companies have significantly increased their flaring, as well as the venting of natural gas and other potent greenhouse gases directly into the atmosphere, according to data from the three largest shale-oil fields in the United States.”  The Daily Climate published an op-ed piece by Derrick Z. Jackson, a Union of Concerned Scientists Fellow in climate and energy, about the efforts by the natural gas industry to paint itself green.  Although green hydrogen is still very much in its infancy, investors and policymakers are starting to take note.  Consequently, Green Tech Media took a brief look at ten countries beginning to move on this potentially important energy source.

Volvo Cars is targeting a 40% reduction in the carbon footprint of each car it manufactures by 2025 and aims to become fully climate neutral by 2040.  Toward that end, it introduced its first fully electric vehicle, a battery-powered version of its small SUV, the XC40.  Ford announced on Thursday it has developed a 12,000-strong charging station network, called the FordPass Charging Network, that its future electric-vehicle owners will be able to take advantage of.  In a two-part series, Utility Dive and Smart Cities Dive explored the question of how cities and utilities are preparing for the expected increase of electric vehicles in the transportation mix.  (Part I; Part II)

By 2022, 30% of the electricity consumed by state agencies and institutions in Virginia will come from renewable sources, under a new agreement between the Commonwealth and Dominion Energy.  The 12-MW Coastal Virginia Offshore Wind project being developed by Dominion Energy and Orsted US received federal approval of two important permits.  An analysis by Carbon Brief revealed that during the third quarter of 2019, UK electricity production by solar, wind, biomass, and hydropower beat out production by fossil fuels for the first time.  Although many U.S. electric utilities are promising net zero carbon emissions by 2050, most plan to rely heavily on coal and natural gas for decades.  That means continuing increases in CO₂ concentrations in the atmosphere.  In an opinion piece in the NYT, Justin Gillis wrote “What the events in California and Miami and Houston tell us is that we are living through the risks of an altered climate now, not a hundred years from now.  Expect the situation to keep getting worse for the rest of your life.”

In an interview with Reuters, Ben van Beurden, CEO of Shell, expressed concern that some shareholders could abandon them due partly to what he called the “demonization” of oil and gas and “unjustified” worries that its business model is unsustainable.  “Despite what a lot of activists say, it is entirely legitimate to invest in oil and gas because the world demands it,” he said.  To illustrate that point, India is investing $60 billion to build a national gas grid and import terminals by 2024 in a bid to cut its carbon emissions.  So how can we rein in oil and gas?  The Guardian presented eight ideas.  Calm has returned to the streets of Quito after Ecuador’s government agreed to reinstate fuel subsidies following eleven days of nationwide, violent protests.

Rob Hopkins, co-founder of the Transition movement, has a new book entitled From What Is to What If: Unleashing the Power of Imagination to Create the Future We Want.  At The New Yorker, Rachel Riederer reviewed two new books dealing with the “stark inequality of climate change”: This Land Is Our Land by Jedediah Purdy and The Geography of Risk by Gilbert Gaul.  Although written from an Australian perspective, Iain Walker and Zoe Leviston’s article about the three forms of climate change denial is equally applicable to the U.S.  There was an interesting article in the NYT entitled “How Guilty Should You Feel About Flying?”.  At Yale Climate Connections, Michael Svoboda continued his summary of recent climate-related reports released so far this year.

These news items have been compiled by Les Grady, member and former chair of the CAAV steering committee. He is a licensed professional engineer (retired) who taught environmental engineering at Purdue and Clemson Universities and engaged in private practice with CH2M Hill, the world’s largest environmental engineering consulting firm. Since his retirement in 2003 he has devoted much of his time to the study of climate science and the question of global warming and makes himself available to speak to groups about this subject. More here.

Politics and Policy

On Wednesday, Democratic presidential candidate Sen. Elizabeth Warren detailed a new environmental justice plan aimed at bolstering and protecting vulnerable communities on the front lines of the climate crisis.  The need for such a plan was illustrated by a study of FEMA’s buyout program published Wednesday in the journal Science Advances.  At The New York Times, Lisa Friedman looked at why young climate activists are not impressed with either former Vice President Joe Biden’s climate plans or his climate record.  U.S. mayors are seeking to go over President Trump’s head and negotiate directly at next month’s UN climate change conference in Santiago.  Senate Democrats plan to use the Congressional Review Act to try and repeal the Trump Administration’s replacement for the Clean Power Plan.  Meanwhile, across the Atlantic, eight EU states have called on the bloc’s incoming top climate official to raise the CO₂ reduction target for 2030 to 55% from 40%.

Virginia ranked 29th in the 2019 State Energy Efficiency Scorecard released earlier this month by the American Council for an Energy-Efficient Economy.  This caused reporter Elizabeth McGowen to write “If Virginia is ever to bust loose from its middle-of-the-pack state ranking on energy efficiency, its regulated utilities must be the prime movers and shakers.”  In a letter to North Carolina Gov. Roy Cooper dated Thursday, Drew Shindell, Nicholas Professor of Earth Science at Duke University, said that the state should place a “permanent moratorium” on new natural gas infrastructure in the state, including the Atlantic Coast Pipeline (ACP).  Nevertheless, the U.S. Supreme Court has agreed to hear an appeal by Dominion Energy Inc of a lower court ruling that halted construction of the ACP.  Nick Martin of The New Republic sees new pipelines coming everywhere. 

In a study released on Thursday, the International Monetary Fund (IMF) joined a chorus of other studies calling for a price on carbon emissions.  The IMF study found that a global tax of $75 per ton by the year 2030 could limit the planet’s warming to 2°C, although others have recommended a much higher tax.  The Vice Chairman of the Board of Swiss drug company Roche said business must set more ambitious goals for reining in human impact on climate and the environment.  A poll conducted by YouGov Blue and Data for Progress sought to determine voters’ reactions to some of the recent proposals by Democratic candidates for fighting climate change.  Robinson Meyer reviewed the findings at The Atlantic.

Two new reports from the Center for Global Energy Policy at Columbia University addressed the question of how to decarbonize industrial heat, i.e., the heat used to do things like make steel, glass, or cement.  The first report is about the current state of industrial heat technology (decarbonizing is hard) whereas the second addresses policy recommendations for decarbonizing the sector (a carbon tax only ranked fifth among the policies).

Climate and Climate Science

Scientists in Siberia have discovered regions with very high atmospheric methane concentrations.  The methane is coming from melting permafrost.  One source is under the East Siberian Sea and is releasing so much methane that the sea looks like it is boiling in some places.

The New York Times has published detailed maps of total transportation-based CO₂ emissions and emissions per capita for many metropolitan areas around the U.S., based on data from Boston University’s “Database of Road Transportation Emissions”.  The Times also had an article about the formation of ghost forests along the mid-Atlantic coast, caused by the migration inland of salt water as a result of sea level rise and a decreased flow of fresh water as a result of drought.

Two recent articles, one last month in Scientific Reports and one this week in Science Advances, shed light on the forces causing accelerated melting of the glaciers in Antarctica.  Be sure to watch the video, in which Ian Howat of Ohio State University does a good job of explaining what is happening.  More rapid melting is also occurring in Greenland, contributing at least 25% of sea level rise.  Science has a rather lengthy article about efforts in Greenland to better understand the melting there, thereby improving scientists’ ability to predict how rapidly sea level will rise.  There is also an interesting video associated with this research.  In South America, nearly 30% of Peru’s glaciers have melted away since 2000, threatening a critical source of drinking water and irrigation for millions of people downstream, according to a new study published in the journal The Cryosphere.  Unfortunately, such melting of mountain glaciers is happening all over the world with similar consequences, as detailed in the new IPCC report on oceans and the cryosphere. 

The National Audubon Society released a new report on Thursday detailing how the ranges of 389 North American birds will change as Earth warms.  Brad Plumer of The New York Times used that report to examine what will happen to the state birds of several states.  A new paper in the journal Science has found that by 2050, up to 5 billion people may be at risk from diminishing ecosystem services, particularly in Africa and South Asia.

NOAA announced that September 2019 tied for the second-warmest September on record in the Lower 48 states.  In addition, hundreds of weather stations from the Mississippi River to the East Coast broke high temperature records for the period Oct. 1-3.  The records weren’t confined to the U.S., however, with records also being set in Europe.

In a study published in the journal Science Advances, scientists found that some coral colonies damaged by oceanic warming from climate change can regrow and fill out the empty skeletons they left behind.  The process is slow, however, suggesting that its success will depend on the frequency of ocean warming events.

Energy

This year’s Nobel Prize in Chemistry has been awarded to the pioneers of the lithium-ion battery.  NASA recently received an all-electric aircraft, the X-57 Maxwell, that will undergo testing in the coming months with the first flight expected in 2020.  British inventor Sir James Dyson said that the company that bears his name is scrapping its plans to build an electric car, even though its engineers had developed a “fantastic” one.

A new report from the Center for American Progress noted that the U.S. needs to get to 65% renewable electricity by 2030 to be on track for 100% renewables in 2050, the level scientists say is needed to avoid the worst impacts of climate change.  The report also looks at what needs to happen in key sectors to meet that goal.  Many think wind power will supply the majority of U.S. renewable energy.  Philip Warburg reviewed the history of wind power in the U.S.

In order to reduce the risk of forest fires during periods of high winds, Pacific Gas & Electric Co. began cutting electricity to 800,000 customers in California this week.

In the U.S. all utility scale facilities combining renewable energy with energy storage use alternating-current coupling.  Now, utilities are studying direct-current coupling, which requires less equipment and promises to be less expensive.

The Guardian has launched a new series entitled “The polluters”.  The first article was published Wednesday and reveals the 20 companies whose exploitation of the world’s fossil fuel reserves can be linked to more than one-third of all greenhouse gas emissions since 1965.  George Monbiot had an opinion piece to accompany the article.  At the New Yorker, Bill McKibben wrote that in order to make progress, Americans need to stop believing in the fable that the U.S. has already made great progress in cutting its greenhouse-gas emissions.  Michael Svoboda presented summaries with links of 12 reports about climate change, its impacts, and building resilience against them at Yale Climate Connections.  Jane Fonda is moving to Washington, DC, for four months to engage in civil disobedience over climate change on the Capitol steps each Friday.  A new wave of climate protests hit cities around the world this week—this time aimed at shocking people with civil disobedience, fake blood on the pavement, and bodies lying in the streets under signs that read: “Stop funding climate death.”  “Carbon Ruins” is a museum exhibit that looks back on the fossil fuel age from the perspective of 2050 after global net-zero CO₂ emissions had been achieved.

Politics and Policy

In contrast to most proposed legislation for a carbon tax, a new paper in the Proceedings of the National Academy of Sciences suggests that the best strategy for applying one is to start high (e.g., over $100/ton or more), rise for a few years, and then fall gradually.  David Roberts examined the implications of that suggestion.  Pennsylvania, one of the nation’s largest coal and natural gas producing states, is starting the process to join the Regional Greenhouse Gas Initiative (RGGI).  On Wednesday, Citigroup issued a report entitled “Managing the Financial Risks of Climate Change,” in which it said that financial regulators must transform how they account for the economic risks of a climate change.  Perhaps the failure to do so is why the majority of the world’s 50 largest banks have not made commitments to respond to the risks of climate change and continue to finance fossil fuels.

Because there were no new commitments from the big emitters at the recent UN Climate Action Summit, many considered it to be a failure.  However, dozens of announcements on climate action were made over the three-day summit.  With a view toward accountability, Climate Home News published a (non-exhaustive) list of initiatives, promises, and goals.  In an opinion piece in The New York Times, Professor Alex Rosenberg of Duke University explained why climate change is such a hard problem to solve, introducing the concept of PPE in the process.

On Monday, the White House announced that President Trump intends to nominate James Danly to be a commissioner on the Federal Energy Regulatory Commission.  But he broke with a decades-old tradition by not nominating a Democrat along with Danly.  A nonpartisan taskforce of former government officials has warned that the treatment of science by the Trump administration has hit a “crisis point”.  The Trump administration’s recent revocation of California’s authority to set its own tailpipe emission standards was seen by many as an assault on states’ rights.  E&E News had an article entitled “Meet the ‘NIMBY people’ trying to kill solar.”  A report from the Rhodium Group shows that passing a few tax incentives for electric cars, nuclear plants, and renewable power could lead to big carbon cuts.  An article in The Hill stated “The Trump administration, in its push for drilling in the Arctic National Wildlife Refuge, is arguing the project should go forward because ‘there is not a climate crisis.’”

A growing body of evangelical leaders is ramping up pressure on Republican lawmakers to reduce U.S. greenhouse gas emissions, breaking from some evangelicals’ long skepticism of climate change.  On the NBC News website, researcher Malka Older argued that the U.S. government must recognize the economic threat caused by extreme weather associated with climate change and prepare for it.  On Tuesday, a coalition of New England and mid-Atlantic states, known as the Transportation and Climate Initiative, took a first step toward limiting transportation emissions across 13 states.  After the recent rash of fire and extreme weather events, the Federal Reserve’s regional banks are digging deeper into how Earth’s warming will impact U.S. businesses, consumers, and the country’s $17 trillion banking system.

Climate and Climate Science

High temperature records were set all over the southeastern U.S. on Wednesday.  A new study by World Weather Attribution found that since 1900, the chances of receiving the amount of rain dumped on Southeast Texas by Tropical Storm Imelda has more than doubled, while the amount of rainfall in such an event has increased by about 18%.

Salt water continues to move farther inland in Florida’s Biscayne Aquifer (Miami-Dade County), although at a slower rate, according to new U.S. Geological Survey mapping.  In Australia, parts of northern and inland New South Wales, along with southern Queensland, have been in drought since 2016, severely depleting river and lake levels, threatening water supplies for many towns and cities.

Throughout the last 500 million years, the period when complex animal life has existed on Earth, the carbon cycle has been in balance for more than 99% of the time, but not now.  National Geographic went along with scientists to learn more about the huge peat deposit in the Democratic Republic of Congo, the scale of which was only recognized a few years ago.  Because of the amount of carbon it contains, it must remain intact.

An iceberg slightly larger than Oahu, Hawaii, broke off this week from the Amery Ice Shelf in East Antarctica.  The loss of Arctic ice is making it very difficult for polar bears to feed, causing their future to be uncertain.  The Washington Post published a photo-essay on Thursday about the impacts of the melting permafrost in Siberia. 

Coral bleaching occurs during ocean heat waves as a result of corals ejecting the algae with which they live in symbiosis.  If bleaching events occur in rapid succession, the corals can be killed.  Now, new research published in the journal Scientific Reports provides hope by suggesting that corals may be able to cope with these stressful events by controlling which algae reside within them.

A good deal of press has been given to carbon capture and sequestration (CCS) as a component of any plan to hold the global average temperature increase below 1.5°C.  CCS will require the development of a complex infrastructure but there currently is no economic incentive for doing so.  Some propose, however, that we first focus on carbon capture and utilization (CCU), in which economic benefits are gained through use of the captured carbon.  David Roberts is publishing a four-part series at Vox explaining how CCU might serve as an on-ramp for eventual large-scale application of CCS.  Part 1 was published September 4 and presented a brief introduction to the need for CCS and the various types of CCU that might help get it going.  Part 2 was published October 2 and focused on the largest industrial use of captured CO₂: enhanced oil recovery.  Parts 3 and 4 will appear later.  It may be too early to judge whether it will pan out, but scientists and engineers in Canada believe they have developed a way to extract in situ hydrogen from tar sands, while leaving the carbon in the ground.  The hydrogen would provide a clean energy source.

The powering past coal alliance (PPCA), which seeks to establish a global coal phase-out by 2050 at the latest, now has 91 members, all vowing to end the construction of new coal-fired power plants by 2020.  On the other hand, the New South Wales government is considering legislation that could limit the ability for planning authorities to rule out coal mine projects on the basis of the climate change impact of emissions from the coal once it is burned.  China plans to shut a total of 8.66 GW of obsolete coal-fired power capacity by the end of this year, the National Energy Administration said.  In the U.S., a group backed by anonymous donors launched a campaign on Monday to promote the benefits of cheap, abundant natural gas against what it called “radical” proposals like the Green New Deal that would phase out use of the fossil fuel.  On the other hand, opponents of new natural gas pipelines are arguing that their builders are misusing eminent domain.  Meanwhile, the U.S. Supreme Court will take up the issue of whether the Atlantic Coast Pipeline can cross two national forests and the Appalachian Trail.

The Virginia Department of Environmental Quality has issued permits for the construction and operation of four new solar projects that will generate a total of 192 MW of electricity.  A modeling study conducted by the Greenlink Group found that adding at least 49 GW of solar energy through 2050 would save Virginia consumers money.

The largest windfarm in the world will have a combined capacity of 3.6 GW and will be located at Dogger Bank off the coast of Yorkshire in the North Sea.  The turbines will be GE Renewable Energy’s Haliade-X, which have a capacity of 12 MW each and stand 853ft tall with blades that extend 351ft.  The vast majority of offshore wind farms employ turbines fixed to the ocean floor, but waters off the coast of California are too deep for that technology.  Floating turbines offer a solution, but only a few have been tried, all in Europe.  Utility Dive examined the possibility of employing floating turbines in California.  Bloomberg Businessweek examined why it is so hard to get an offshore wind farm built in the U.S. and the A.P. addressed Trump’s dislike for the industry.

At Energy Storage News, Stefan Hogg addressed the need for lithium-ion battery recycling and the challenges facing the industry in developing a system.

On September 20, David Wallace-Wells began publishing a series of interviews at Intelligencer, part of New York Magazine.  The series is entitled “The State of the World: A series about climate change” and comprises in-depth interviews with climate leaders about their views on the future of Earth’s climate.  A list of the interviewees can be found here.  Another article from mid-September that I want to call to your attention focused on the psychological impact of climate change on children.  On that same theme, PBS News Hour presented an article advising how to talk to your children about climate change.  Yale Climate Connections has reposted two short essays from The Conversation by Australian scientists working on the Great Barrier Reef, one near the end of his career, the other near the start of hers.  At The Tyee, Professor Jennifer Ellen Good addressed the link between continual economic growth and climate change, concluding that the news media ignore the clear connection.  On Monday in Harrisonburg, Innovation Hub aired a segment entitled “Fools for Fossil Fuels: A History of Climate Change Inaction.”  Three scientists have been named MacArthur ‘Genius Grant’ Fellows for their work related to climate change.  The Yale Program on Climate Change Communication has updated its “Climate Opinion Maps,” including a new question on whether the President should do more to address global warming.

These news items have been compiled by Les Grady, member and former chair of the CAAV steering committee. He is a licensed professional engineer (retired) who taught environmental engineering at Purdue and Clemson Universities and engaged in private practice with CH2M Hill, the world’s largest environmental engineering consulting firm. Since his retirement in 2003 he has devoted much of his time to the study of climate science and the question of global warming and makes himself available to speak to groups about this subject.
