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.
CONTINUE READINGHurricane 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 …

CONTINUE READINGLet’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.

Here are some recent developments at leading universities.
Universities across the country are making moves to better address climate change: creating new Schools of Sustainability and Climate, establishing research institutes, and appointing Vice Provosts for Climate Change to oversee their work.

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.” …

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 …

CONTINUE READINGNo, 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 …

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 …

An update on the serious and the silly
Solar geoengineering has been prominent in the news lately. It looks like the long-predicted spike of attention to these potential climate responses may finally be starting – with many attendant opportunities for controversy and confusion. For background on solar geoengineering, why it’s important to research, and what the debates over it are, check out various …

Some important people in the climate arena are Black. But there are far too few of them.
Since this is Black History Month, I thought it would be appropriate to talk about some of the prominent contributions by Blacks to understanding and addressing climate change. Blacks are badly underrepresented in STEM fields such as atmospheric science and in environmental groups, but there are some important exceptions.(STEM stands for ‘Science, Technology, Engineering, and …
