CONTINUE READINGMilestones in State Climate Policy
The first efforts to clean up the grid date back forty years, but state climate policy really got moving at the turn of the century.
The federal government’s interventions in climate policy have been erratic, driven by political polarization and alternating control of the White House. In contrast, state governments have engaged in steady campaigns to reduce carbon emissions. Some people seem to think this has been a recent innovation, but it has now been ongoing for a generation. Here are some the key milestone along the way, closing with Trump’s pledge to bulldoze state policies that don’t fall in line with his priorities.

After a year of Trump 2.0, here’s how things stand.
Eight years ago almost to the day, I wrote a post titled, “One Year and Counting.” I was writing at the end of Trump’s first year in office. And here we are again, one year into a second Trump Administration. Trump’s basically deregulatory strategy has remained largely unchanged. But there are some notable differences in the situations then and now. I closed my 2017 post with this: “One characteristic of the Trump Administration is a ceaseless stream of controversies and dramas. But generally speaking, the amount of actual legal change has been much more limited, because the system is designed to provide checks on administrative and legislative action.” It remains to be seen how well those checks will function this time around.

Science funding has been spared the worst cuts for now, but don’t believe the hype — and know that the White House has more tricks up its sleeve.
The topline headlines look great: CNN: Trump wants to slash funding for federal climate and weather research. Congress is about to tell him ‘No’ Reuters: US Senate passes bill to boost federal science spending after White House sought major cuts NBC: Congress passes bill to fund U.S. science agencies, rebuffing Trump’s requested cuts And there …

CONTINUE READINGThe U.S. Has Now Become a Rogue Nation
By pulling out of the UNFCCC and dozens of international organizations, Trump has isolated the United States and ceded influence to China and the EU.
In the past few days, Trump has kidnapped the head of state of Venezuela, threatened to invade Greenland, and withdrawn from a 1992 climate treaty negotiated by George H.W. Bush. The treaty, the U.N. Framework Convention on Climate Change, has been the basis for international climate cooperation for the past thirty years, including the Paris Agreement. In addition, Trump is withdrawing from the Intergovernmental Panel on Climate Change (IPCC), which will make it harder for American scientists to contribute to the periodic reports on the state of climate science. Trump’s action is basically a big middle finger toward the rest of the world. If anyone wins from this, it’s China, which can now claim to be the responsible adult in the room.

Here are six big things to watch.
What to watch for environmentally in 2026: court tests of Trump’s power, midterms, China, grid issues, and state energy moves. In 2025, Trump rolled out new initiatives at a dizzying rate. That story, in one form or another, dominated the news. This year, much of the news will again be about Trump, but he will have less control of the narrative. Legal and political responses to Trump will play a greater role, as will economic developments. Trump’s anti-environmental crusade could run into strong headwinds.

Despite the Trump Administration’s attempts to bring the world into the dark ages, lots of light is blazing
I’m a pretty pessimistic guy. Finding the dark cloud behind the silver lining is something of a specialty for me. But maybe at the end of an atrocious year for environmental law and policy in the United States, we should look for the good news, and thanks to the good people at Canary Media, there …

CONTINUE READINGEveryday Christmas: The Gift of the Commons
Clean air. Clean water. We receive these public goods every day without payment
One of the Christmas classics is the Jimmy Stewart movie, It’s a Wonderful Life. George Bailey, Stewart’s character, is despondent about his life until he learns how much he has unknowingly helped others and how grateful they are. It’s heartwarming, if also a bit corny. There’s a flip side to that story: the need to remember …

CONTINUE READINGFederalism, AI, and the Environment
Trump’s efforts to overturn state laws are part of his effort to consolidate power and suppress opposition.
State authority isn’t unlimited, but current legal doctrines give it broad scope. So, apparently, does national politics, given that Congress recently rejected a proposal to preempt state AI laws and has never seriously considered preempting state climate laws.
As we all know, Congress has found it extraordinarily difficult to enact legislation on major issues. The executive branch, under the Supreme Court’s “major questions doctrine,” lacks the power to fill the gap. That leaves only the states to save us from paralysis when major new issues arise. That may not be ideal, but it’s better than nothing.
