Preventing methane leaks is in my top five climate solutions. This is very stupid. https://www.nytimes.com/2026/10/27/climate/trump-methane-rules-epa-greenhouse-gas.html?unlocked_article_code=1.L1E.z5jG.PZOg8NpQXZ1N&smid=bs-share

The greatest challenge of our time isn’t to figure out how to get to Mars or become interstellar, but to figure out how to live sustainably on Earth.

If we were to cut emissions by 18% in four years, that’s about the same rate of decrease as in 2020 during COVID-19 when the whole world shut down. 🫠 https://www.theguardian.com/environment/2026/oct/21/world-cut-emissions-un-climate-crisis?CMP=us_bsky&utm_medium=Social&utm_source=Bluesky#Echobox=1792595368-1

Heat storms, massive heat waves covering at least 1% of the globe for five consecutive days, have become increasingly frequent and severe. These storms were rare in the 1960s, but now average 102 per year, causing widespread heat-related deaths, wildfires, and droughts. https://www.reuters.com/investigates/special-report/climate-heatstorms-science/

Just as fossil fuel companies and their cronies sow doubt about scientific knowledge on climate change in order to prevent the development of non-fossil fuel resources, they’re doing the same thing now to climate attribution science to avoid accountability for climate damage. Pay attention!

Lol.

IMHO, attribution science, which connects specific extreme weather events to climate change, is the most important area of climate science. https://www.nytimes.com/2026/10/06/opinion/oil-companies-supreme-court.html?unlocked_article_code=1.GlE.qxRX.hiyBCfMWY7xj&smid=url-share

CRANE, a UK cybersecurity research network, used AI to desk-reject 50% of proposals before human review, including one on the risks of trusting AI models in voice analysis from Lancaster University forensic linguist Claire Hardaker. This seems like AI doing the right thing in protecting itself. 🙃 This is a joke. It’s horrifying. https://www.science.org/content/article/u-k-funder-uses-ai-triage-reject-grant-proposals-leaving-researchers-dismayed?referrer=https%3A%2F%2Fwww.science.org%2Fconten...

I don’t think everyone realizes how bad things are for US science: For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget. https://www.nytimes.com/2026/10/02/us/politics/national-science-foundation-research-funds.html?unlocked_article_code=1.F1E.adOl.I5OvE-oZxF24&smid=nytcore-ios-share

When climate scientists say things are going to be horrendous, people find out many years later that we’re right. With this El Niño, the “find out” part will come in months.

I appreciate The New York Times for bringing Kelvin Waves into the vernacular. It's a concept that even those in Earth and environmental sciences (besides physical oceanographers) struggle to grasp, but everyone should be exposed to real scientific explanations. https://www.nytimes.com/2026/09/30/climate/el-nino-storm-flooding-kelvin-waves.html?unlocked_article_code=1.FlE.3czz.vTzTJ4i2x4io&smid=url-share

Turns out we don’t have to invoke weapons of mass destruction when talking about ocean heat uptake. The ocean absorbed a record-breaking 23 zettajoules of heat last year, equivalent to 40 times the energy used by humanity. It’s not going to end well. https://www.theguardian.com/environment/2026/sep/30/worlds-seas-warmed-23-zettajoules-2025

Ospreys are disappearing along the US East Coast due to a shortage of Atlantic menhaden, a crucial food source for ospreys. One company alone harvested nearly 300 million pounds of the fish in 2024 but somehow claims they’re not at fault. 🧐 https://wapo.st/4d6dwxB
