How climate change is worsening drought

By Naomi Cohen-Shields / Published: April 30, 2021

Spring is in full swing across the U.S. – flowers are blooming, pollen is blowing – and this means that the 2021 heat wave, hurricane, and wildfire seasons are just around the corner.

After the 2020 Atlantic hurricane season produced a record number of named storms and record-breaking wildfires ravaged the Western U.S., vulnerable communities are bracing for more. However, another extreme weather event linked to climate change has been quietly afflicting the U.S. year-round with no signs of letting up and at risk of becoming permanent – widespread drought.

Drought conditions have been ongoing since early summer 2020 – and have persisted, worsened, and expanded dramatically – across vast portions of the continental U.S. Since October 2020, almost all of the High Plains and Western regions and more than half of the South have been experiencing some level of drought. More than 50% of Western drought conditions are categorized as either extreme or exceptional drought. Even more drastically, extreme and exceptional drought have comprised more than 75% of drought conditions across the Four Corners region (Arizona, Utah, Colorado, and New Mexico) since late autumn.

NOAA predicts that these widespread dry conditions are likely to continue and spread throughout the spring, especially in the Southwest. This poses major threats to the region, including increased risks of wildfires, parched rangelands, stressed irrigation systems, and crop failures.

Just as climate change has worsened many extreme weather events, it has also impacted droughts. The excess heat now trapped in the climate system draws out more moisture from soils, thereby worsening drought conditions. Reduced snowpack volumes, earlier snowmelt, and changing precipitation patterns – also linked to climate change – exacerbate the water stress induced by droughts. And for numerous individual events across the world, scientists have attributed the increased likelihood and severity of droughts to human-driven climate change.

The Wall Street Journal says electric vehicles are better – but underestimates how much

By Jamie Fine / Published: April 7, 2021

A recent Wall Street Journal article answers definitively YES to the question of whether electric vehicles are really better for the environment. But even this strong endorsement of electric vehicles underestimates just how good these cars, trucks and buses will be for our climate and air.

The article reports findings from researchers at the University of Toronto. The researchers compared vehicle emissions for a 2021 Toyota RAV4 and a Tesla Model 3. The study is clear that operations are cleaner for electric vehicles.  With each mile driven, the electric vehicles’ environmental performance outpaced gasoline-powered cars, quickly wiping out the slightly higher production emissions for electric vehicles.

Even with a relatively dirty fossil-fuel-based electricity generation mix and metal-intensive battery materials, this study – which looked only at a snapshot of technology as it is today – found that electric vehicles break even with gasoline-powered cars at about 20,000 miles of lifetime usage. And that break-even point is getting lower quickly, as electric vehicle technology accelerates faster than a Polestar with a tailwind.

The benefits of clean trucks and buses: thousands of lives saved, less pollution, more jobs

By Peter Zalzal / Published: March 12, 2021

Passenger cars have been leading the way, so far, in the development of zero emission technologies. But there’s also a movement underway to develop heavy-duty electric vehicles – like freight trucks and buses – that could have sweeping benefits for the climate, public health, and American jobs.

At EDF, we just released a new report, Clean Trucks, Clean Air, American Jobs, that analyzes the effects of eliminating tailpipe pollution from those medium and heavy-duty vehicles – including buses, semis and other long-haul trucks, and the “last-mile” trucks that deliver packages to American homes.

Our report found that a rapid transition to zero-emitting freight trucks and buses will significantly reduce dangerous air pollution – pollution that disproportionately burdens lower income neighborhoods and communities of color.

Air pollution standards that ensure all new heavy-duty trucks and buses sold for urban and community use are zero-emitting by 2035, and all such vehicles sold are zero-emission by 2040, would:

  • Prevent a sum total of more than 57,000 premature deaths by 2050
  • Eliminate a sum total of more than 4.7 billion metric tons of climate pollution by 2050.
  • Significantly reduce two main components of smog – nitrogen oxides pollution by a sum total of more than 10 million tons by 2050, and particulate pollution by a sum total of almost 200,000 tons by 2050
  • Save $485 billion in health and environmental benefits alone as a result of pollution reductions.

Senators Manchin, Stabenow and Daines lay out plan to boost manufacturing and innovation

By EDF Blogs / Published: March 10, 2021

By Toby Short, Associate Vice President, Federal Affairs

My father and grandparents worked in the textile mills in North Carolina. When those mills closed, the once vibrant towns that housed the mills began to shut down as well. My father, being young at the time, ended up moving to find work. But my grandparents stayed because that was the life and the community they knew. And we’ve seen this same story all across America.

A bipartisan group of senators – including Joe Manchin, Debbie Stabenow and Steve Daines – is trying to reverse that trend.

America’s domestic manufacturing once formed the backbone of our country and was the envy of the world. Towns and cities flourished as manufacturing increased, not only lifting up the people that worked in these factories, but the local economies as well. Read More »

Five things to know about the Texas blackouts

By EDF Blogs / Published: February 24, 2021

1. Our first priority must be to help Texas families

Millions in Texas were without power and drinkable water for days on end, and families across the state are still working to find food and assess the damage from burst pipes. Helping them must be our first priority.

2. Climate change means all of our infrastructure may be more vulnerable to extreme weather. But Texas’ grid wasn’t ready for extreme cold and winter storms.  

While there will be much finger pointing in the days to come, it’s becoming clear that the biggest problem is that ERCOT, the state’s grid operator, as well as the Texas Public Utility Commission that oversees it, haven’t prepared the state’s electricity grid for more extreme weather, including winter storms which may become more common with climate change.

Leaders at all levels should make sure not only power facilities, but all of our infrastructure, is built with resilience in mind & factor climate change impacts in planning. We need policies from the state to ensure Texas is ready.

As the Texas Tribune said, “Texas officials knew winter storms could leave the state’s power grid vulnerable, but they left the choice to prepare for harsh weather up to the power companies — many of which opted against the costly upgrades.”

3. Fossil fuel lobbyists are trying to spin the truth, but natural gas and coal were the biggest part of the problem.

Eleven facts about clean vehicles to counter gas guzzling lobbyists

By EDF Blogs / Published: February 11, 2021

The average American household spends about $175 a month on gasoline. That means billions of dollars to oil companies, refiners, and others — and a huge incentive for them to block policies that move America to clean, zero-emissions electric vehicles.

We’re already seeing a coordinated push to stop our leaders from boosting American clean cars, trucks and buses — even though these policies will create jobs and a more just and equitable economy, clean the air, and are popular with the public.

EDF experts have assembled these facts to counter the lobbyists who want to make sure Americans keep paying at the pump.

1. Moving to clean electric vehicles will help America win the race for good jobs today and tomorrow. 

The question isn’t electric vehicles versus gas-powered vehicles — the global industry is already moving to EVs, and spending at least $257 billion this decade to make the switch. The issue is whether American workers will get these jobs. We can build these vehicles in places like Hamtramck, MI and Spartanburg, SC or have them shipped to us from Hamburg and Shanghai. Switching to zero-emissions electric trucks, buses, and cars will create jobs today and help us compete with Europe and China in this rapidly expanding market. Read More »
