Avskogning kan driva Amazonas mot en kritisk gräns under 2030-talet

Rapporterad av AI

En ny studie visar att fortsatt avskogning i Amazonas kan utlösa omfattande återgång av regnskogen vid en global uppvärmning på så lite som 1,5 grader. Forskare varnar för att den kritiska gränsen kan nås redan 2031 om skogsförlusten uppgår till 22 procent.

Forskare vid Potsdam Institute for Climate Impact Research har modellerat de kombinerade effekterna av stigande temperaturer och avskogning fram till 2050. Deras resultat visar att den kritiska uppvärmningströskeln för att Amazonas ska börja tyna bort sjunker med cirka 2 grader när skogsförlust inkluderas, jämfört med tidigare uppskattningar som inte tog hänsyn till avskogning.

Study finds global warming rate has doubled since mid-2010s

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.

Scientists debate causes of accelerating global warming

16 mars 2026 Rapporterad av AI

Building on recent studies like Stefan Rahmstorf et al.'s analysis showing a doubling of Earth's warming rate to ~0.36°C per decade since 2014, scientists disagree on whether reductions in aerosol pollution or natural fluctuations are driving the speedup. Nearly all agree warming has accelerated, but views differ on causes, rate, and future trajectory—with implications for climate sensitivity and adaptation.

Blind spot could force 132 million to flee rising sea levels

A new study warns of an interdisciplinary blind spot that could force 132 million people to flee rising sea levels, which could rise by up to 150 centimeters. Swedish oceanographer Ola Kalén at SMHI describes the acceleration of sea level rise since the 1960s as shocking.

Methane levels surged unexpectedly in early 2020s

10 februari 2026 Rapporterad av AI

Atmospheric methane concentrations rose at an unprecedented rate in the early 2020s, driven by a weakened natural removal process and increased emissions from wetter landscapes. Scientists attribute much of the spike to a drop in hydroxyl radicals during 2020-2021, combined with climate-driven boosts from wetlands and agriculture. The findings underscore the interplay between atmospheric chemistry and weather patterns in global greenhouse gas trends.
