Methane, Exposed

A map what in overhead view of lush terrain shows a heat map overlay with hues of blue, green, yellow, and red.

Two new reports from the UCLA Emmett Institute reveal some of the largest methane sources in 2025.

One of the transformations in the climate policy world over the last few years has been the (rightful and helpful) rise in focus on methane pollution. For a long while, carbon dioxide was the attention-grabbing greenhouse gas, the one at which most policy initiatives were aimed. And CO2 remains critically important, of course. But folks …

Policy Implications of Accelerating Warming

News from a Warming Planet

If warming is coming more quickly, we need to pick up the pace on policy responses.

There seems to be an emerging scientific consensus that the rate of global warming is rising.  After screening out the effects of natural factors like El Niño, scientists have concluded that the pace of warming has roughly doubled since the 1970s.  What does this tell us about policy?  Some of the implications are more obvious than others, and at least one implication may be unsettling for some climate advocates. Most obviously, we need to accelerate our efforts to carbon emissions.  We will be closing in on possible tipping points faster than expected. Climate impacts that we might have expected twenty years from now could hit in half that time.

Has Trump Actually “Driven a Dagger Through the Heart” of Climate Policy?

News from a Warming Planet

Lee Zeldin

Don’t jump to conclusions based on the Administration’s spin operation.

there’s a good chance that the repeal of the Endangerment Finding will be reversed by the courts.  That would ground federal climate policy even more firmly in the law, so the Administration is taking a gamble.  Saying they’ve one is as premature as a roulette player who’s just put all their chips on one number announcing that they’re now rich before the wheel has even started turning. Even if the courts do uphold the repeal, a lot will depend on just what legal theory the judges adopt. Some legal theories would slam the door on efforts by future Democratic presidents. Others would leave room to move forward.
