Climate 411

Is the media making the connection between wildfires and climate change?

With entire towns in Oregon and Washington razed, ash raining down on Denver and the skies over San Francisco an apocalyptic orange, the unprecedented wildfire season in the Western U.S. is getting plenty of coverage. But much of it seems to ignore a central fact: This devastation — more frequent, bigger wildfires, and a longer fire season — is largely a consequence of climate pollution produced by burning fossil fuels.

The way it works is easy to understand. Rising temperatures, a key component of climate change, evaporate more moisture from the ground, drying out the soil and making vegetation more flammable. At the same time, winter snow-packs are melting about a month earlier, meaning that the forests are drier for longer periods of time. Meanwhile, shifting meteorological patterns can drive rain away from wildfire-prone regions, a phenomenon scientists previously discovered in California and have linked in certain cases to human-made climate change.

Even before this year’s devastating season, we’ve seen a dramatic increase in the damage caused by wildfires. The average wildfire season in the West is three and a half months longer than it was a few decades back, and the number of annual large fires has tripled — burning six times as many acres.

Our new report shows the importance of “accelerating to 100% clean” vehicles

Air pollution is the largest environmental cause of disease and death in the world. In the U.S. almost half of all people live in communities with unhealthy levels of air pollution. More than 20,000 Americans die prematurely every year as a result of the motor vehicle pollution on our roads and highways, according to a new peer reviewed study by EPA  experts. Pollution from our roadways disproportionately harms people of color and lower income communities. Transportation sector pollution is now also the largest source of climate pollution in the U.S.

A new EDF report includes these facts and other comprehensive information about the dangers of transportation sector pollution and about strategies to address it. The report, Accelerating to 100% Clean: Zero Emitting Vehicles Save Lives, Advance Justice, Create Jobs, compiles the best and most recent information on the issue.

Here are a few key findings. Read More »

Creating a cleaner and more affordable power sector in North Carolina

For more than a year, dozens of advocates and stakeholders – including the electric utilities – have been working together on North Carolina’s Clean Energy Plan development process, which calls for creating a 21st century energy system that is clean, affordable, reliable and equitable. As discussions have progressed in ongoing working groups to explore policy pathways for climate action and systemic utility regulatory reform of North Carolina’s power sector, we recently learned that over the past several months, the major electric utilities across the southeast have been engaged in a separate dialogue on a proposal to create an automated market for trading among the utilities.

We must not let these conversations distract from real opportunities to achieve Governor Cooper’s ultimate goal of moving North Carolina to a clean energy future. The electric power sector is the largest source of climate-warming pollution in North Carolina, making up 35% of the state’s emissions. Gov Cooper has committed the state to doing its part to address pollution from this sector, and both the state and Duke Energy have set goals to achieve net zero carbon emission from the power sector by 2050.

What you need to know about hurricanes and climate change

This post was co-authored by EDF Postdoctoral Climate Science Fellow Tianyi Sun

Today Hurricane Laura made landfall in Louisiana as a Category 4 hurricane, causing death and destruction. Louisianans and Texans in its path are now mourning and looking ahead to a long and painful recovery.

Laura had winds up to 150 miles per hour, making it one of the strongest hurricanes on record to ever hit the Gulf Coast in the United States. It tied the record for how quickly it intensified, driving questions about the role of climate change in creating and fueling this monster storm.

A look at the latest science

Scientists have been actively studying how climate change affects hurricanes for decades, and the evidence that it can influence several aspects of hurricanes continues to grow.

Overall, climate change is making these already dangerous weather events even more perilous. They are stronger, wetter, slower, and intensify more rapidly. Major storms are occurring more often and piling on heavier rainfall, and scientists anticipate the strongest storms will continue to increase in frequency. Sea level rise, along with stronger winds, are also worsening storm surges, causing more coastal flooding.

All aspects of hurricanes – from formation to track to strength to damages – can be influenced to some degree by climate change, through warmer waters, more moisture in the atmosphere, changing air patterns, and sea level rise.

For some connections, such as how climate change affects hurricane strength and its damages, the science is simple and robust. For other connections, such as how climate change affects hurricane formation and track, the science is more complicated and nuanced.

Here we break down what we know about how climate change affects four key aspects of hurricanes

Western Climate Initiative auction strengthens as state has opportunity to increase its climate ambition

The results of the latest Western Climate Initiative cap-and-trade auction were announced today and showed stronger demand for allowances than in the May auction. This meant significantly higher revenue for California’s Greenhouse Gas Reduction Fund.

While the auction was still undersubscribed for the second quarter in a row, this is not a surprising outcome due to the ongoing COVID-19 crisis, the renewed closures in parts of California’s economy, and the overall economic uncertainty.

Pennsylvania legislators seek to protect workers, ratepayers and our climate

As Gov. Tom Wolf and the Department of Environmental Protection (DEP) move forward to advance meaningful climate action in Pennsylvania, legislators are also stepping up with a new complementary bill. Last month, state Senate Minority Leader Jay Costa introduced legislation with 17 of his colleagues that charts a course to a cleaner, more sustainable power sector for Pennsylvania. The bipartisan “Energy Transition and Recovery Act,” (Senate Bill 15) will ensure carbon emissions from Pennsylvania’s power sector reach net zero by mid-century and demonstrates strong leadership on the most significant environmental issues facing the state.

Introduction of S.B. 15 followed attempts by some in the legislature to halt progress being made to address carbon pollution by passing H.B. 2025, legislation that essentially stops action being taken by DEP to link with the Regional Greenhouse Gas Initiative (RGGI). Legislators supporting H.B. 2025 offered no solution to address climate change, protect workers and communities, or reduce air pollution and instead opted to obstruct action on climate that is supported by 79% of Pennsylvanians.

Here is what Sen. Costa’s bill would do:
