States and financial bodies using modelling that ignores shocks from extreme weather and climate tipping points

The world has entered an era of “global water bankruptcy” that is harming billions of people, a UN report has declared. The overuse and pollution of water must be tackled urgently, the report’s lead author said, because no one knew when the whole system could collapse, with implications for peace and social cohesion. All life depends on water but the report found many societies had long been using water faster than it could be replenished annually in rivers and soils, as well as over-exploiting or destroying long-term stores of water in aquifers and wetlands.

“Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and ensuring energy security. Carbon capture and storage, biofuels, new nuclear and other technologies are expensive wastes of time, he argues.

UN GEO report says ending this harm key to global transformation required ‘before collapse becomes inevitable’

Compromis, mesures volontaires et absence de mention des combustibles fossiles : points clés de l’accord de la COP30 […] Le sommet des Nations unies sur le climat COP30 a fait avancer la lutte contre la crise climatique et les dommages qu’elle cause déjà aux vies et aux moyens de subsistance. Mais les mesures convenues constituent des pas en avant, plutôt que les bonds en avant nécessaires.

Delegates made minimal headway on timetable for replacing oil and gas or on firm commitments to reducing carbon emissions

A deal is welcome after talks nearly collapsed but the final agreement contains small steps rather than leaps

Une analyse magistrale de 5 000 ans de civilisation soutient qu’un effondrement mondial est imminent si les inégalités ne sont pas éliminées. […] Nous ne pouvons pas fixer une date pour la fin du monde, mais en examinant les 5.000 ans de [civilisation], nous pouvons comprendre les trajectoires auxquelles nous sommes confrontés aujourd’hui et l’autodestruction est la plus probable », déclare le Dr Luke Kemp du Centre for the Study of Existential Risk (Centre d’étude des risques existentiels) de l’université de Cambridge (*).

Action urgently needed to save the conditions under which markets – and civilisation itself – can operate, says senior Allianz figure

Het internationaal afgesproken klimaatdoel van maximaal 2° C opwarming is "dood". Dat zegt de gerenommeerde klimaatwetenschapper James Hansen. Volgens hem is de snelheid waarmee de Aarde opwarmt zwaar onderschat en dreigen we versneld af te stevenen op extreme weerfenomenen en klimaatrampen.

Analysis shows fossil fuels are supercharging heatwaves, leaving millions prone to deadly temperatures

Thirteen of the ports with the highest supertanker traffic will be seriously damaged by just 1 metre of sea level rise, the analysis found. The researchers said two low-lying ports in Saudi Arabia – Ras Tanura and Yanbu – were particularly vulnerable. Both are operated by Aramco, the Saudi state oil firm, and 98% of the country’s oil exports leave via these ports.

Prof James Hansen says pace of global heating has been significantly underestimated, though other scientists disagree
