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 …

Climate Change and Black History

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 …

The Fuss about Methane

Part 1: Science and weird facts

Methane is getting a lot of attention in climate debates. There was even a “Methane Day” last Tuesday at the climate conference in Glasgow. Several new regulations controlling methane emissions have been adopted recently, including two new rules for the US oil and gas sector announced last week. There’s a new informal international agreement to …

Hot 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 …

Speaking 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, …

How Hot Will Things Get?

Identifying a realistic worst case scenario is complicated.

How hot will the world be in 2100? The answer partly depends on how much carbon we dump in the atmosphere between now and then. It also depends on how sensitive the climate system is to those emissions. Scientists have used 4.5 °C as the high end of the likely possibilities. That estimate derives from …
