What If We Succeed?
If we “beat” climate change, what will we have to show for it?
Suppose we bring climate change under control and deal with its fallout. What will have we achieved? We will have prevented great harm. That, of course, is the main goal. Untamed climate change means an dangerous, ugly future for all of us on “Spaceship Earth.” Preventing that future is surely enough of a reason to …

CONTINUE READINGHot off the Press: The New IPCC Report
The latest science confirms the need for urgent action.
The IPCC issued the massive first volume of its new report on climate change on Monday. This volume focuses on climate science: how much will the world warm, and what will the impacts be? The bottom line is that the evidence is becoming ever firmer that (a) humans are causing an unprecedented rate of climate …

An opinion piece in the NY Times reveals a disconnect between history and what we expect from wildfires and air quality
There’s a lot of news coverage about the wildfires on the West Coast right now, and rightly so. But with that news coverage comes a lot of commentary, some of which might lead us down the wrong policy path. I want to highlight an example from the New York Times opinion page, not because it …

CONTINUE READINGSpeaking Truth to Corporate Power
Decades ago, industry scientists fought to get their bosses to pay attention to climate change.
Decades ago, their own scientists told car companies and oil companies about climate change, information the companies chose to ignore. The scientists were voices crying out in the corporate wilderness. Sadly, they were ignored at the time, but companies are starting to pay the price for that in lawsuits. Those scientists advocated for the truth, …

The future of effective climate policy requires balancing equity, efficiency, political feasibility, and technological innovation
In the prior blog post in this two-part series, I talked about how current debates on climate policy that are focused on equity and efficiency are inadequate. Today, I’ll explain how we might advance political feasibility through climate policy, how that is connected to technological innovation, and how we must necessarily balance between all four …

Moving the debate beyond equity and efficiency
As Congress debates two large pieces of legislation – both a bipartisan infrastructure bill and a partisan reconciliation package – a key question is the extent to which either piece of legislation (assuming it is enacted) addresses climate policy. And the recent flooding in Europe, the wildfires in the western US and Russia, and more …

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 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 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 …

BP P.L.C. v. Baltimore Ruling a Technical Win for Energy Defendants–But There’s Less There Than Meets the Eye
Today the U.S. Supreme Court issued its first major environmental decision of the Court’s current Term–and in a climate change case, no less: BP P.L.C v. Mayor and City Council of Baltimore. Superficially, the multinational energy corporations sued by the City of Baltimore prevailed, in a 7-1 majority opinion authored by Justice Neil Gorsuch. But …
