Canada in Flames
What’s causing the fires? What harm do they do? What should we do?
One of the world’s great disasters is unfolding, as fires have covered millions of acres in Canada, destroying pristine ecosystems and poisoning the air for millions of people. Something like seven million acres have already burned. The U.S. government’s response is to threaten Canada with tariffs, apparently as punishment for allegedly having poorly managed its forests. Instead, we should be partnering with Canada on forest management, and we should cut the greenhouse gas emissions that are ramping up the fire risk.

Hey, it’s not all gloom and doom out there.
We don’t lack for bad news these days. Still, there are also good things happening. I’ve been putting together a list of things that are good news for the environment. EVs, battery storage, and solar are growing around the world. So put on your happy face!
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In the past few days, Trump has kidnapped the head of state of Venezuela, threatened to invade Greenland, and withdrawn from a 1992 climate treaty negotiated by George H.W. Bush.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.
CONTINUE READINGThat Was the Year That Was
2025 had a lot of bad environmental news, but also a few rays of hope.
2025 has been a dark time for Americanswho care about the environment. Rather than being a repeat of his first term, which had been bad enough environmentally, Trump’s second term has been a tsunami of bad news. Besides some outright rollbacks, Trump has done his best to purge the government of programs and people implementing environmental law. Much of that has been illegal but effective anyway. The demolition of the East Wing will be remembered as a defining moment, the perfect metaphor for an Administration that has religiously embraced the motto, “move fast and break things.”
CONTINUE READINGThoughts on COP30
What have we learned about the future of climate negotiations?
we can only expect incremental progress from the U.N. unless or until China takes a leadership role, particularly while the U.S. is also on the sideline. Incremental progress is better than no progress, obviously. But we’re going to have to look elsewhere for productive international action.
Basically, that’s going to have to rely on something less than the international consensus that drives COP. That means doubling down on some other options: bilateral climate agreements between countries, action by coalitions of interested countries, and subnational agreements including states, provinces, and cities around the world.

One after another, Trump has let loose destructive blasts at the environment to promote fossil fuels, mining, and logging.
We all know that Trump has issued a slew of executive orders since taking the oath of office. We also know that many of these are aimed to promoting fossil fuels, mining, and logging at the expense of the environment, while disfavoring renewable energy. Still, it’s impressive when you put the list together to see the full onslaught.
CONTINUE READINGBrazil Steps Ahead of the U.S. on Climate Policy
A new emissions trading system is a major step for Brazilian climate policy.
Hopefully, Brazil’s actions will encourage other countries, particularly in South America, to take similar actions. The EU and California have been leaders in this arena, but carbon trading systems are now beginning to get traction outside of the developed world in China and now Brazil. That’s an encouraging sign.
CONTINUE READINGTouched by the Keeling Curve
Teaching the Keeling Curve in International Environmental Law has me reflecting on the role of climate science then and now.
Teaching the climate change unit last week in my International Environmental Law and Policy class, I found myself so moved that I started crying at the board. My poor students thought I was in distress. I was simply telling the story of the Keeling Curve. That’s a daily record of global atmospheric carbon dioxide concentration devised by …

A short history of climate action in Europe’s economic powerhouse
We need to understand the history of climate action as we plan for the future. In terms of climate leadership, Americans tend to think of California. At the global level, however, Germany has its own claim to a leadership role, particularly in its early support for renewable energy. It has helped to shape EU climate …

CONTINUE READINGMexico y el Cambio Climático
There is much to celebrate tomorrow on Cinco de Mayo. But probably not Mexican climate policy.
President Andrés Manuel López Obrador (generally known as AMLO) could be described as a left-leaning populist. Like other populist leaders, he has not been friendly to climate action. In November, Mexico ramped up its 2030 commitment under the Paris Agreement from 22% to 35%. That sounds like great news, but there may be less to …
