Risk of Atlantic Current Collapsing Much Higher Than Previously Expected

Unsurprisingly, climate risks keep growing. However, it’s not great to hear that one of the possibilities that has concerned me the most for almost two decades is getting more likely. That is the collapse of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC brings warm water from tropical parts of … [continued]

Fossil-Fuelled Heat Has Caused Tropical Birds to Decline by “Up to 38%” since 1950s

An uptick in heat extremes, driven by human-caused climate change, has caused tropical bird populations to decline by up to 38% since the 1950s, according to a first-of-its-kind analysis. The study combines ecological and climate attribution techniques to trace the fingerprint of fossil-fuelled climate change on declining wildlife populations. It … [continued]
