Global Warming

A new analysis in Geophysical Research Letters shows Earth warming at ~0.36°C per decade since 2014—about double the prior rate of 0.18°C per decade—with 98% confidence after accounting for natural factors. Led by Stefan Rahmstorf, the study warns the Paris Agreement's 1.5°C limit could be breached by 2028, amid debates over short-term trends and data uncertainties.

A new modelling study indicates that a weakening Atlantic Meridional Overturning Circulation is causing the Gulf Stream to drift northwards, with satellite data showing a 50-kilometre shift over 30 years. Researchers suggest this gradual change could precede an abrupt move serving as an early warning for a potential AMOC collapse. Such a collapse might lead to drastic cooling in Europe, though timelines remain uncertain.

Following initial coverage of accelerated global glacier losses projected by ETH Zurich researchers, the full study—published December 15, 2025, in *Nature Climate Change*—reveals precise disappearance timelines for Earth's ~211,000 glaciers. Limiting warming to 1.5°C preserves ~100,000 by 2100 (versus 18,000 at 4°C), with 'Peak Glacier Extinction' hitting 2,000 glaciers lost in 2041 under low warming or 4,000 in 2055 at high levels.

A new cross-national study reports that higher temperatures are associated with slower progress in young children's early learning. Children exposed to average maximum temperatures above 86 °F (30 °C) were less likely to reach basic literacy and numeracy milestones than peers in cooler conditions, with the greatest impacts observed among children in economically disadvantaged households.
