Scientists Declare 2°C Climate Goal Impossible, Warn of Severe Warming

A new analysis led by climatologist James Hansen declares that keeping global warming to the 2 degrees Celsius target set by the Paris Agreement is now 'impossible.' The study highlights that Earth's climate is more sensitive to greenhouse gas emissions than previously understood, compounded by a decline in sunlight-blocking aerosols from shipping, which has raised temperatures. Projections suggest that temperatures will stay above 1.5°C soon, with the potential to reach around 2.0°C by 2045, causing severe damage to ecosystems like coral reefs and increasing the likelihood of extreme weather events. The analysis warns that the shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could occur within the next two to three decades, leading to significant sea-level rises. While Hansen's findings are controversial and debated within the scientific community, they emphasize the urgent need for global action against climate change. Experts stress that this situation represents a critical point of no return, urging policymakers to reassess climate strategies immediately.
