Major International Climate Developments
China and the EU took important steps forward this week.
This week has seen some big climate moves on opposite sides of the world. The EU has proposed a major new climate plan. Meanwhile, China is ready to go live with its emissions trading system. The U.S. is at risk of being left behind. The EU’s proposal is impressive. The goal is to cut net …

CONTINUE READINGEarth System Interventions for Sustainability
We actively shape major Earth systems, with increasingly powerful technologies. We should face up to it.
Stewart Brand–a contender for the most interesting living person in the world–famously opened the Whole Earth Catalogue in 1969, “We are as gods and might as well get good at it.” Importantly (and often misunderstood), he meant not that we are gods, but instead that technologies have given humanity powers that had previously been exclusive …

CONTINUE READINGCalculating the Extinction Cost of Carbon
Or, how many megatons do we need to cut to prevent one extinction?
Economists often talk about the social cost of carbon, which basically translates the harm done by a ton of CO2 into dollars. The dollar metric is less useful as applied to ecological impacts like species extinctions than impacts of humans. It may be better to skip the dollar conversion, and just ask how much a …

CONTINUE READINGClimate News from Capitol Hill
There are small but hopeful signs of progress in overcoming legislative gridlock.
Over a decade ago, the Waxman-Markey carbon trading bill died in the Senate. President Obama then had to rely entirely on administrative actions to address climate change. Republicans united in a solid wall of violent opposition to climate action. There are some hopeful signs that things may not be quite so tough for President Biden. …

CONTINUE READINGFacing Up to Reality
More frequent heat waves. Droughts. Wildfires. The West is getting a glimpse of its future climate.
The western U.S. is staring climate change in the face. Most of the West is experiencing “severe” or “exceptional” drought. We could be heading into the worst drought period in centuries. Major dam reservoirs are down to record low levels. The region is also in the grips of a record-breaking heatwave. We can expect another …

CONTINUE READINGWhy I Was Wrong About Methane
I didn’t think cutting methane was a high priority. Now I do. Here’s why.
I didn’t use to think that eliminating methane emissions should be a priority. True, methane is a potent greenhouse gas. But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. In contrast, CO2 emissions cause warming for 2-3 centuries or more. So methane emissions seemed to be something …

CONTINUE READINGThe Hidden Green-Infrastructure Bill
Every year, Congress provides lavish funding for clean energy and climate adaptation. No one notices.
Biden’s green-infrastructure bill is headline news. Republicans are up in arms. Yet every year there’s already a green-infrastructure bill. Hardly anyone notices. Republicans vote for it without a fuss. Why? It’s part of the annual funding bill for the military. The Defense Department remains the biggest single consumer of energy in the country, and it …

CONTINUE READINGAnti—Anti-#ClimateEmergency
Whether to declare a climate emergency is debatable. But some critics have gone way overboard.
Should Biden declare a national climate emergency? There are certainly arguments that, on balance, it would be better not to take that step. Some opponents argue that declaring a climate emergency would be horribly anti-democratic, polarizing, and counterproductive. Those arguments seem to me seriously overstated. I’d like to go through the major arguments against declaring …

CONTINUE READINGWhat Have We Learned from Recent Disasters?
Disasters are getting bigger, badder, and less predictable. We need to adjust.
Hurricanes Harvey and Maria. California wildfires. Superstorm Sandy. The great Texas blackout. The list goes on. These mega-events dramatize the need to improve our disaster response system. The trends are striking: escalating disaster impacts, more disaster clustering, more disaster cascades, and less predictability. We need to up our game. Lisa Grow Sun and I discuss …

CONTINUE READINGThe Turning Tide
Last week featured some remarkable developments relating to climate policy.
Some events last week sent a strong signal that the tide is turning against fossil fuels. Each of the events standing alone would have been noteworthy. The clustering of these events dramatizes an important shift. To paraphrase Churchill, this may not be beginning of the end for fossil fuels, but at least it is the …
