2°C Climate Target Unreachable: Scientist Declares ‘Game Over’
New research by Professor James Hansen suggests the pace of global heating has been severely underestimated, rendering the 2°C target unattainable. This conclusion stems from findings that both the impact of reduced shipping pollution and climate sensitivity to increased emissions are higher than previously believed. These results, while at the high end of current estimates, cannot be dismissed and indicate a significantly accelerated warming trajectory, potentially triggering critical tipping points like the collapse of the Atlantic ocean currents. Unless drastic action is taken, including potentially exploring solar geoengineering, the study projects a 2°C rise by 2045.
