    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&amp;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&amp;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&#39;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&amp;smid=url-share

    A Democratic-led coalition of cities and states, including Hawaiʻi, is suing the Trump regime for repealing rules limiting greenhouse gas emissions from power plants. https://www.theguardian.com/environment/2026/oct/01/us-states-cities-trump-epa-climate-emissions?utm_source=dlvr.it&amp;utm_medium=bluesky&amp;CMP=bsky_gu_env

    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

    Here’s another way climate change will kill us: the expansion of mosquitoes and the deadly diseases they carry. In Paris, the invasive Asian tiger mosquito (Aedes albopictus), an aggressive, day-biting nuisance, is now everywhere. So excited to get Dengue, Chikungunya, and Zika in Paris. https://to.pbs.org/4ihm3ks

    In the cost-benefit analysis of mitigation and adaptation, do you think French bureaucrats are saying to themselves, &quot;Well, that&#39;s a few thousand pensioners that we no longer have to pay&quot;? It&#39;s as good an explanation as any for the lack of action. https://www.lemonde.fr/en/france/article/2026/09/16/french-health-authority-reports-almost-8-000-excess-deaths-over-heatwave-struck-summer_6757604_7.html?srsltid=AU7gw4Uevi6-ViaL2A-eoT-Gxl86GGQYNv4ruFLV3JwfO-LrqnskyaGd

    The US Senate finds that the fossil fuel industry received $190 billion in tax breaks and subsidies from the Trump regime in exchange for campaign donations. The deregulation and subsidies have increased both energy costs for Americans and the damage from climate change and air and water pollution. https://www.theguardian.com/us-news/2026/sep/24/fossil-fuels-trump-donations?utm_source=dlvr.it&amp;utm_medium=bluesky&amp;CMP=bsky_gu_env

    Every time I return to Paris, I notice they&#39;ve done more to reclaim streets from drivers and cars, including removing on-street parking, protecting cyclists from drivers, and prioritizing pedestrians and cyclists in shared spaces. Other cities can learn a lot from Paris.
