EPA Moves to Ignore Power Plant Carbon Emissions, Deny Climate Science Zeldin is proposing to walk away from regulating carbon emissions from power plantsโ€”plus nearly every other source of heat-trapping emissions.

As UCSโ€™s Julie McNamara explains, in a handout to the fossil fuel industry, EPA is attempting to argue that climate pollution from coal- and gas-fired power plantsโ€”responsible for about a quarter of all US heat-trapping emissionsโ€”isnโ€™t worth regulating.

Despite Clear Preferences from Texas Hill Flood Survivors, Uncertainty Looms Residents of Texas Hill Country testified about what recovery means to them. Who will listen?

Check out this powerful blog by one of my colleagues on Central TX flash flood survivors speaking out in a TX legislative session. "What is clear is that the brave people of Texas Hill Country have joined the growing list of disaster survivors across the country who canโ€™t afford inaction."

Great reporting here on the absolute bogus DOE report that cherrypicks and misleads readers on the scientific consensus behind climate change. Never forget one of the authors, Koonin, was a chief scientist at BP for 5 years!

Hot Summer 2025 Could Be the Coolest for the Rest of Our Lives: 6 Things to Know It's hot and getting hotter. But climate action is cool.

#KillerHeat is... killing us๐ŸŒก๏ธ ๐Ÿ’€. The ocean is losing its cool๐ŸŒŠ๐Ÿฅต. We're making a U-turn away from solutions. (!!!). BUT heat responds quickly to reduced emissions if we #ActOnClimate.

#DangerSeason is baking us. And this could be the coolest summer for the rest of our lives. This is #ClimateChange

Trump Administration Attempts Burying Climate Change Evidence to Further Fossil Fuel Agenda If there aren't government records of climate change, is climate change still happening? (Yes.)

Congress must reclaim its power-of-the-purse authority to halt attacks on vital agencies and safeguards and work quickly to undo the damage already done. The answer to worsening #DangerSeason will never lie in anti-science solutions. Can we count on you to push back @lisamurkowski.bsky.social?

โ€œHydroclimate Whiplashโ€: How Extreme Rainfall and Drought Are Linked The same atmospheric conditions that cause droughts can also produce extreme rainfall. Marc Alessi explains the whiplash.

Check out my explainer blog on how more intense extreme rainfall events and drought are linked as the Earth continues to warm:

Fossil Fuel Companies Make Billions in Profit as We Suffer Billions in Losses As fossil fuel companies report record-breaking profits, losses from damages driven by climate change continue to mount.

Now, those same companies are begging for immunity from court cases in multiple states where they're being sued for lying to the public about their knowledge of climate change and covering up what they knew as much as possible.

Big Oil has been lying to us for decades: Donโ€™t let it off the hook Blatant attempts to grant polluters nationwide immunity show just how far some officials will go to deny communities their day in court.

My colleague at @ucs.org, @kathymulvey.bsky.social, wrote an excellent article published in The Hill discussing Big Oil's role in spreading climate change misinformation, despite the fact that they knew about it since the 1970s.
