Global emissions plunged an unprecedented 17 percent during the coronavirus pandemic

Chris Mooney, Brady Dennis and John Muyskens, WASHINGTON POST

But scientists say the drivers of global warming could quickly bounce back as social distancing ends and economies rebound.

The wave of shutdowns and shuttered economies caused by the coronavirus pandemic fueled a momentous decline in global greenhouse gas emissions, although one unlikely to last, a group of scientists reported Tuesday.

As covid-19 infections surged in March and April, nations worldwide experienced an abrupt reduction in driving, flying and industrial output, leading to a startling decline of more than 1 billion tons of carbon dioxide emissions. That includes a peak decline in daily emissions of 17 percent in early April, according to the study published in the journal Nature Climate Change. For some nations, the drop was much steeper.

Scientists have long insisted that the world must scale back carbon pollution significantly — and quickly — to mitigate the worst effects of climate change over coming decades, although none have suggested that a deadly global pandemic is the way to do so.

Tuesday’s study projects that total emissions for 2020 will probably fall between 4 and 7 percent compared to last year — an unheard-of drop in normal times, but considerably less dramatic than the decline during the first few months of the year when economies screeched to a halt. The final 2020 figure will depend on how rapidly, or cautiously, people around the world resume ordinary life.

The unprecedented situation produced by the coronavirus has offered a glimpse into the massive scale required to cut global emissions, year after year, to meet the most ambitious goals set by world leaders when they forged the 2015 Paris climate accord. Last fall, a U.N. report estimated that global greenhouse gas emissions must begin falling by 7.6 percent each year beginning in 2020 to avoid the worst effects of climate change.

‘Ozone friendly’ chemicals are polluting the environment

Jordan Davidson, ECOWATCH

The Montreal Protocol of 1987 committed nations around the world to stop using the chlorofluorocarbons (CFC) that created a hole in the ozone layer. While it stands as one of the most effective environmental commitments the globe has seen, new research shows the side effects have been costly as chemicals dangerous to human health build up in the environment, as the BBC reported.

New research published in the journal Geographical Research Letters analyzed Arctic ice and found an unintended consequence of the Montreal Protocol. The compounds that replaced CFCs have been transported and transformed in the atmosphere, depositing far from their sources. The new generation of chemicals that replaced Freon, but are used in refrigerators, air conditioners and new cars have been accumulating since 1990.

“Our results suggest that global regulation and replacement of other environmentally harmful chemicals contributed to the increase of these compounds in the Arctic, illustrating that regulations can have important unanticipated consequences,” said Cora Young, a professor at York University in Canada, and an author of the paper, in a York University statement.

Scientists first discovered ozone depletion in the 1970s when they detailed the deterioration of the stratospheric ozone layer around the earth’s poles. As the hole over Antarctica opened and expanded, scientists found that the depletion of ozone was responsible for a greater intensity of ultraviolet radiation from the sun, causing an increase in the prevalence of skin cancer, eye cataract disease and other harmful effects on humans, as Courthouse News reported.

Scientists were soon able to pinpoint manufactured chemicals used in air conditioners and refrigerators, as well as solvents, propellants and chemical agents found in foam as the cause of the depleted ozone layer.

Now pollution from the chemicals that were created to replace the CFCs, known as short chain perfluoroalkyl carboxylic acids (scPFCAs), has proliferated around the world. The replacement chemicals are a class of PFAS, or forever chemicals, that have polluted waterways and made groundwater in certain areas toxic to drink.

Governor’s May revision to California budget proposal puts air quality, other environmental outcomes at risk

Kathryn Phillips, SIERRA CLUB CALIFORNIA

Governor Gavin Newsom released his May revision of his January budget proposal today and environmental quality is among the revised budget’s most hard-hit victims.

Since January, the state has suffered a dramatic shutdown in economic activity due to the COVID-19 pandemic. The current budget estimate by the Department of Finance continues to be that the state will suffer a $54.3 billion deficit.

In his May revision, the governor proposes cutting general fund contributions to the California Environmental Protection Agency by more than 94 percent. That agency houses departments and boards that oversee air pollution control, water quality, and pesticide and toxic substance control.

Moreover, about $83 million in funds collected by the California Air Resources Board from fees and settlements from polluters will be shifted over to the Department of Toxic Substance Control and the State Water Board “to reduce costs” for those two entities.

The May budget proposal also eliminates a biodiversity program proposed in January, and raids a fund for habitat conservation to spend the money for other purposes.

The proposal mentions that $995 million in funds from the Greenhouse Gas Reduction Funds collected through the cap-and-trade program will be prioritized for a list of programs. It is unclear whether those programs will include funding for incentives to accelerate transition of diesel and gas buses and heavy-duty trucks to zero-emission electric trucks and buses.

Statement of Kathryn Phillips, Director of Sierra Club California:

“Nobody envies this governor or legislature for the job they need to do in this tragic year to balance the state’s budget.

“But cutting and shifting funds away from key environmental programs that will protect the basic needs of life—clean air, clean water, healthy ecosystems—is the wrong approach.

“We look forward to working with the legislature to refine this budget to make sure it doesn’t slow the march toward a healthy environment for everyone in California.”

Scott Dam slated for removal in plan by Sonoma County and partners to control hydropower project

Guy Kovner, THE PRESS DEMOCRAT

Enviro Updates: From the Eel River Action Plan 2016, by California Trout: “The Eel River is the third largest river entirely in California.The Eel River ecosystem, its salmon and steelhead populations, and other native fish and wildlife populations have been in decline for the past century and a half. It has been transformed from one of the most productive river ecosystems along the Pacific Coast to a degraded river with heavily impaired salmonid populations.”

A nearly century-old dam on the Eel River that impounds Lake Pillsbury is slated for removal under a $500 million proposal helmed by Sonoma County and four other regional partners seeking to take over from PG&E a remote but pivotal hydropower project in Mendocino County.

The coalition, including Mendocino and Humboldt counties, hailed the proposal as a milestone in their effort to meet the needs of all three counties, protecting water supplies for farmers, fish and communities, including a key source of supplemental water for the Russian River system that serves 600,000  customers in Sonoma and Marin counties.

The dam removal alone, a long-sought goal of environmental groups and fish advocates, would be the highest-profile project to improve habitat for imperiled North Coast salmon and steelhead in decades, perhaps behind only the dam removals planned on the Klamath River within the next two years.

“The good news is that Scott Dam is coming out,” said Scott Greacen, conservation director for Friends of the Eel River, a nonprofit that for decades has been pursuing removal to open up more than 300 miles of spawning habitat in the upper Eel. Due mainly to dams, water diversion and other development, the river’s salmon and steelhead “have paid a devastating price, going from a million fish a year to the brink of extinction,” he said.

The proposal, submitted Wednesday to federal officials, has also stirred passions among those dismayed by the prospective loss of a 2,300-acre recreational lake deep in the Lake County portion of Mendocino National Forest. Santa Rosa residents George and Carol Cinquini, who have held a cabin at Lake Pillsbury since the 1940s, are annoyed that the 450 homeowners, ranchers and small business owners in the lake community were excluded from the planning process.

“We tried to get our foot in the door,” said Carol Cinquini, vice president of the Lake Pillsbury Alliance, which was formed last year.

“We’re very upset,” said George Cinquini, an alliance board member. The reservoir, about two hours from Santa Rosa is a haven for water sports, and without it, Cinquini warned, Russian River flows will be diminished in dry years.

But North Coast Rep. Jared Huffman, D-San Rafael, who brought local shareholders together to chart the project’s future, said the proposal is the only way to guarantee a “really important water resource” for the Russian River.

The 98-year-old dam has long outlived its purpose, he said, and the coalition project, dubbed the Two-Basin Partnership, calls for habitat restoration “to rejuvenate one of our great salmon rivers in California.”

State Sen. Mike McGuire, D-Healdsburg, whose district stretches across both drainages, called for Lake County to be added to the partnership because Lake Pillsbury and most of the Eel River’s headwaters are in the county.

Seattle will permanently close 20 miles of residential streets to most vehicle traffic

Michelle Baruchman, THE SEATTLE TIMES

Nearly 20 miles of Seattle streets will permanently close to most vehicle traffic by the end of May, Mayor Jenny Durkan announced Thursday.

The streets had been closed temporarily to through traffic to provide more space for people to walk and bike at a safe distance apart during the coronavirus pandemic.

Now the closures will continue even after Gov. Jay Inslee’s stay-at-home order is lifted.

Over the next couple of weeks, the Seattle Department of Transportation (SDOT) will replace the temporary closure signs on the so-called Stay Healthy Streets with permanent markings, guiding drivers to other routes.

The program, which has rolled out in phases, has been implemented in the Aurora-Licton Springs, Ballard, Central District, West Seattle, Greenwood, Othello, Rainier Beach and Beacon Hill neighborhoods.

Residents, delivery drivers, garbage and recycling workers, and emergency response vehicles can continue to use the streets, but no through traffic is allowed.

“Our rapid response to the challenges posed by COVID-19 have been transformative in a number of places across the city,” SDOT Director Sam Zimbabwe said. “Some of the responses are going to be long lasting, and we need to continue to build out a transportation system that enables people of all ages and abilities to bike and walk across the city.”

More streets could be closed to through traffic in the coming months, depending on community demand. SDOT will evaluate streets based on whether they reach dense areas, allow people to stay close to home and keep parks from getting crowded, among other factors.

The benefits of headwater forest management

Lori Pottinger, PUBLIC POLICY INSTITUTE OF CALIFORNIA

The health of California’s headwater forests is in decline, leaving them increasingly vulnerable to major wildfires and droughts that threaten the many benefits they provide. Even in the midst of the current COVID-19 pandemic, California must plan for the upcoming fire season, and continue work to reduce its risks. At a virtual event last week, PPIC researcher Henry McCann described how improved management can make Sierra forests more resilient and avoid major wildfire-related disasters, and summarized the findings of a new report that identifies the benefits and beneficiaries of such management practices.

“Expanding on the pace and scale of long-term forest stewardship is going to be a heavy lift for private and public entities,” said McCann. “Developing a clear sense of the benefits and beneficiaries of improving forest health is key to motivating long-term stewardship and identifying the partners to support it.”

An expert panel moderated by study coauthor and UC cooperative extension specialist Van Butsic discussed how this translates into practice.

Watch the video here.

What does the science tell us about managing California’s wildfire- and drought-prone forests? “It tells us there are opportunities for win-win scenarios, where a forest treatment designed to reduce fire risk will likely also have other benefits—for carbon storage, biodiversity, wildlife habitat, water output,” said panelist Carmen Tubbesing, a PhD candidate in forest ecosystems and fire sciences at UC Berkeley.

City leaders aim to shape green recovery from coronavirus crisis

Matthew Taylor and Sandra Laville, THE GUARDIAN

Mayors coordinating efforts to support a low-carbon, sustainable path out of lockdowns

Cities around the world are already planning for life after Covid-19, with a series of environmental initiatives being rolled out from Bogotá to Barcelona to ensure public safety and bolster the fight against climate breakdown.

Mayors from cities in Europe, the US and Africa held talks this week to coordinate their efforts to support a low-carbon, sustainable recovery from the crisis as national governments begin to implement huge economic stimulus packages.

Many cities have already announced measures, from hundreds of miles of new bike lanes in Milan and Mexico City to widening pavements and pedestrianising neighbourhoods in New York and Seattle.

The initiatives are designed to allow people to move around urban spaces safely in a world where physical distancing will be the norm for the foreseeable future – and do so without sparking a drastic increase in air pollution.

The mayors who took part in the newly formed economic taskforce this week believe these initial schemes point the way to more radical long-term measures that will help tackle inequality and the climate crisis.

COVID-19 stimulus measures must save lives, protect livelihoods, and safeguard nature to reduce the risk of future pandemics

Josef Settele, Sandra Díaz, Eduardo Brondizio and Dr. Peter Daszak, Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)

There is a single species that is responsible for the COVID-19 pandemic – us. As with the climate and biodiversity crises, recent pandemics are a direct consequence of human activity – particularly our global financial and economic systems, based on a limited paradigm that prizes economic growth at any cost. We have a small window of opportunity, in overcoming the challenges of the current crisis, to avoid sowing the seeds of future ones.

Diseases like COVID-19 are caused by microorganisms that infect our bodies – with more than 70% of all emerging diseases affecting people having originated in wildlife and domesticated animals. Pandemics, however, are caused by activities that bring increasing numbers of people into direct contact and often conflict with the animals that carry these pathogens.

Rampant deforestation, uncontrolled expansion of agriculture, intensive farming, mining and infrastructure development, as well as the exploitation of wild species have created a ‘perfect storm’ for the spillover of diseases from wildlife to people. This often occurs in areas where communities live that are most vulnerable to infectious diseases.

Our actions have significantly impacted more than three quarters of the Earth’s land surface, destroyed more than 85% of wetlands and dedicated more than a third of all land and almost 75% of available freshwater to crops and livestock production.

Add to this the unregulated trade in wild animals and the explosive growth of global air travel and it becomes clear how a virus that once circulated harmlessly among a species of bats in Southeast Asia has now infected almost 3 million people, brought untold human suffering and halted economies and societies around the world. This is the human hand in pandemic emergence.

Yet this may be only the beginning. Although animal-to-human diseases already cause an estimated 700,000 deaths each year, the potential for future pandemics is vast. As many as 1.7 million unidentified viruses of the type known to infect people are believed to still exist in mammals and water birds. Any one of these could be the next ‘Disease X’ – potentially even more disruptive and lethal than COVID-19.

Earth Day at 50: Why the legacy of the 1970s environmental movement is in jeopardy

Denise Chow, NBC NEWS

Changing global and political landscapes have made the kind of broad and bipartisan agreements reached in the 1970s seem impossible.

The first Earth Day, held on April 22, 1970, marked a turning point for U.S. environmentalism, capturing the growing activism of the 1960s and putting the country on track to create the Environmental Protection Agency and many major pieces of legislation in the 1970s.

Fifty years later, those efforts are at risk of being rendered null.

For the 50th anniversary of the first Earth Day, veteran climate activists are offering words of warning about the changing global and political landscapes that have made the kind of broad and bipartisan agreements reached in the 1970s seem impossible.

“What’s disturbing to me about what’s happened over the last 50 years is this steady drift of the Republican Party toward opposing environmental action and dismantling 50 years of environmental progress,” said Michael Mann, a professor of atmospheric science at Pennsylvania State University.

And with countries around the world in the grips of the coronavirus pandemic, some experts fear that climate action could fall by the wayside as nations attempt to restart their economies. Rather than investing in infrastructure to support renewable energy and focusing efforts on reducing carbon dioxide emissions, for example, countries could revert back to the status quo in a bid to recoup coronavirus-related economic losses.

But the path ahead won’t be easy. Humanity is quickly running out of time to keep global warming below2 degrees Celsius (3.6 Fahrenheit) and slow the most damaging impacts of climate change. And even with aggressive action, the planet is still at risk of rising seas, drought, wildfires, extreme weather and other potentially damaging consequences of the warming that has already happened.

Still, David Muth remembers when taking environmental action wasn’t always a partisan fight.

As the director of Gulf restoration for the National Wildlife Federation, Muth knows that climate policies have always been hard-won, but beginning in the 1960s, as the severity of human-caused pollution was becoming more apparent, people started to demand change.

Friends of Gualala River move to halt Dogwood logging plan

FRIENDS OF THE GUALALA RIVER

Friends of Gualala River (FoGR) recently took legal action to appeal the decision on the Dogwood timber harvest plan (THP) to the State Appellate Court. In addition, FoGR sought an injunction on logging until the appeal could be heard. The court granted the injunction last week which temporarily suspends logging of Dogwood. Gualala Redwood Timber’s (GRT) logging of Dogwood could have commenced as early as April 15. A hearing date for the appeal is presently unknown.

The Dogwood THP includes logging 342 acres of second-growth and mature redwood forest within the sensitive floodplain of the Gualala River. The THP area is located close to the Sonoma County Gualala Point Regional Park Campground, extending up river to Switchville, at the Green Bridge, and continuing along the South Fork which flows parallel to The Sea Ranch and directly across from, and beyond, the “Hot Spot.” Additional tracts of land containing large redwoods are included in the expansive THP including units beyond twin bridges and along creeks in the Gualala River Watershed.

The THP abuts a portion of the main stem of Gualala River which is designated as a Wild and Scenic river by the State of California for its natural beauty and recreational value. The river is also listed as “impaired” by the U.S. Environmental Protection Agency due to excessive sediment and temperature.

FoGR first filed suit to challenge the California Department of Forestry and Fire Protection’s (Cal Fire) approval of Dogwood in 2016. FoGR prevailed in its initial and subsequent suit against Cal Fire on the grounds that Cal Fire failed to comply with the California Environmental Quality Act.
