What to know about climate_change

Researchers from Utrecht University have published a study in Nature Climate Change suggesting that the stability of the Atlantic Meridional Overturning Circulation (AMOC) depends on the rate of global warming rather than just a fixed temperature threshold. The study indicates that rapid warming could trigger a collapse at 2°C, while slower warming might allow the system to remain stable at higher temperatures, suggesting a need for climate policies that limit the pace of warming.

What happened

Rapid warming may tip Atlantic circulation at 2°C, while slower warming may avert collapse Swati Mestri Scientific Editor Robert Egan Senior Editor For several years, climate scientists have shown that the Atlantic Meridional Overturning Circulation (AMOC)…

Why it matters

New research from Utrecht University shows that this picture is incomplete: The pace of warming also determines whether the AMOC stays stable.

Common ground

The study was published in the journal Nature Climate Change.

Claim 3: “this threshold is unrealistically high, meaning that the present-day AMOC is unlikely to become unstable through this contribution alone.”

SINGLE SOURCE

The provided evidence for this claim consists of search results for 'Meltwater' the company, rather than the scientific concept of glacial meltwater thresholds. No evidence was provided regarding the specific threshold value being 'unrealistically high'.
