Global climate body fights for survival: why the IPCC must be saved
The UN organization faces perhaps the most serious crisis in its nearly 40-year history — but it is too precious to lose.

The growth in global greenhouse gas emissions has slowed, from 1.7%/year from 1990-2015 to 0.8%/year from 2016-2025. Nevertheless, global GHG emissions are still at record high levels. Progress? www.unep.org/en/publicati...

In the rush to build data centers, companies are starting to use their own off grid gas generators. This results in much higher emissions – 60% to 80% – compared with using their local electricity grid and risks locking in longer-term fossil dependence. www.theclimatebrink....

JUST POSTED: Today at The NYT we are publishing a major investigation into how President Trump used his executive powers to expose millions of Americans to greater cancer risks. A six month-long investigation built on more than 10,000 pages of FOIA records. Read it www.nytimes.com/2026/10/24/c...
How Trump Gave the Worst Polluters a Free Pass (Gift Article)
The president temporarily waived clean-air rules for industrial facilities that spew cancer-causing gases. Then his appointees worked to gut the regulations altogether.

Trump’s EPA promised to fill vacancies on its only committee protecting youth from pollution and toxic chemicals. Eight months later, seats remain empty. EPA Administrator Lee Zeldin says appointments could come this month. But promises aren’t action, and science must guide the committee’s work. 🧵
A smaller gap but a worse future. Current policies, result in warming being kept below 2.8°C by 2100. The most optimistic case, where all NDCs and net-zero targets are achieved keeps warming to 2.1°C. This is a worsening from last year's report, mainly because of the policy roll-backs in the US.
The 2026 UNEP Emissions Gap Report is out: The Point of Return. 🌍🌡️🔥 It's sobering but actionable. Decades of inadequate climate action have closed off opportunities to limit warming, but ambitious action today can still prevent much greater harm. A thread of some of the highlights 🧵

The 65th Plenary session of IPCC was suspended because the negotiations were going overtime & most small delegations from developing countries (incl. LDCs, SIDS) had to leave on Friday evening. A "plenary" decision taken during the week-end without them would not have been inclusive or fair.

104 jours de chaleur (maximale >= 25 °C) à Paris Montsouris en 2026. Un chiffre probablement définitif qui bat le record de 2018 (98 jours de chaleur). Dans un climat pas si ancien (standards des années 1990) le nombre annuel moyen de jours de chaleur était de 50. Graphe papusa forum @infoclimat.fr
