EPA Jumps the Shark

Just as a past dictator rejected modern genetics, Trump rejects climate science. For both, evidence was no match for ideology and ego.

Honestly, EPA’s embrace of climate denial is just plain embarrassing.  And the rest of the world will justifiably view it as one more sign that the U.S. has taken leave of its senses.  Trump can change the name of a water body on maps, but he can’t change scientific reality. The scientific evidence about the reality of climate change, its causes, and its harms is incredibly well-established.  It’s based on many different types of data and models, which have been tested and retested.

Trump Shoves Economic Analysis and Science to the Curb

The MAGA agenda takes precedence over data and analysis.

If you were looking for data-driven regulatory policy, you’re not going to find it in this Administration.  On the contrary, Trump has marginalized economic analysis and wants to bulldoze environmental science.  Thus, we are likely to get policies that are bad for the environment without being cost-justified, while ignoring policies who environmental benefits outweigh economic costs.

Model Uncertainty in Politics and Climate Policy

The polls could be systematically off, not just due to random error. That’s a worry with climate models as well.

Yes, your favored candidate could sweep the swing states, and yes, climate change could be more moderate than we now expect.  But that shouldn’t give you much comfort on either issue, since the errors could equally be in the opposite directions. 

Obviously, we’d like to improve our models, but that’s not always easy. In the meantime, the smart thing is to plan on the basis of the best models we have but avoid overconfidence about our predictions.

Hurricane Milton and this Climate Moment

We’re witnessing the collision of extreme weather, climate science, national news and politics. The question of “Who pays for climate disasters?” is about to become even more important.

When President Biden addressed the nation yesterday from the White House, he warned that Hurricane Milton could be one of the most destructive storms in more than a century, but he stopped short of explaining why — that climate change, fueled by our burning of fossil fuels, is making oceans warmer and storms stronger, capable …

Let’s Make Tomorrow “National Climate Awareness Day”

Here’s the case for setting aside a day to think about climate change, and why that day should be Aug. 23

Creating National Climate Awareness Day would send a message about the importance of climate change.  It would also provide an occasion to educate Americans about the issue. If it can also celebrate modern science, and the contributions of women to science, all the better.  And all it would take is a Presidential proclamation.

Ripped from the Headlines

This is not, unfortunately, an April Fool’s joke. Not at all.

Here’s a selection of recent headlines, which I only wish I had made up for April Fool’s Day. “Earth just had its hottest year ever recorded — by far.” — NBC “Hurricanes are getting so intense, scientists propose a Category 6”— Washington Post “Parts of Amazon rainforest could tip toward collapse by 2050, study warns.” …

How much should we worry about climate tipping points?

A new report suggests climate tipping events may be inevitable, and urges transformative approaches to climate policy

It’s hard to keep up with the deluge of climate news around COP28. Climate damages are growing. Carbon budgets are running out. Temperature records are being re-written. Despite new pledges, climate action remains hugely insufficient and grossly unfair. And the world may be unable to avoid passing critical climate tipping points. That last comes from …

No, There’s No Scientific Conspiracy About Climate Change

Anyone who thinks otherwise has never met a real live academic.  We can barely conspire about where to eat lunch.

Among the host of conspiracy theories out there, a perennial one depicts climate science as a global hoax perpetuated by scientists. There are thousands of climate scientists around the world, which is an awful lot of people for a secret conspiracy. But even if there were only forty or fifty, a successful conspiracy of any …

2150 and Beyond

Climate change’s long term effects on the planet will be profound.

Most climate change projections end at the end of this century. When the IPCC issued its first report, however, 2100 was  110 years  in the future. Looking that far ahead right now would bring us closer to 2150 than to 2100.  We’re only beginning to get a sense of the impacts of climate change that …
