Carbon cycle feedbacks may amplify global heating risk, study warns

Nonlinear microbial thermal response and its implications for abrupt soil organic carbon responses to warming

Microbial carbon use efficiency (CUE) is a key microbial trait affecting soil organic carbon (SOC) dynamics. However, we lack a unified and predictive understanding of the mechanisms underpinning the temperature response of microbial CUE, and, thus, its impacts on SOC storage in a warming world. Here, we leverage three independent soil datasets (n = 618 for microbial CUE; n = 591 and 660 for heterotrophic respiration) at broad spatial scales to …

Global warming could be stronger than expected in the next 1,000 years, says one study. To prevent this, researchers are now calling for action.

According to a recent study from Germany, global warming could be stronger in the long term than previously assumed. The goal of the Paris Agreement to maintain warming at well below two degrees Celsius is only achievable in "scenarios with very low emissions and with lower climate sensitivity than currently assumed in the best estimate," warned the Potsdam Institute for Climate Impact Research (PIK) on Monday. This is the temperature change of …

Thanks to climate and carbon cycle feedbacks such as thawing permafrost, the two-degree target is becoming more and more unlikely. The Potsdam Institute for Climate Impact Research strongly warns

Carbon cycle feedbacks may amplify global heating risk, study warns

Global heating over this millennium could exceed previous estimates due to carbon cycle feedback loops. This is the conclusion of a new study by the Potsdam Institute for Climate Impact Research (PIK). The analysis shows that achieving the Paris Agreement's aim of limiting global temperature rise to well below 2°C is only feasible under very low emission scenarios, and if climate sensitivity is lower than current best estimates. The paper is the…

HKUST Researchers’ Breakthrough Method Reveals Clouds Amplify Global Warming Far More Than Previously Understood

HKUST Researchers’ Breakthrough Method Reveals Clouds Amplify Global Warming Far More Than Previously Understood - Preview Anonymous (not verified) Wed, 03/26/2025 - 11:05 Tropical marine low clouds play a crucial role in regulating Earth’s climate. However, whether they mitigate or exacerbate global warming has long remained a mystery. Now, researchers from the School of Engineering at the Hong Kong University of Science and Technology (HKUST) …
