New research suggests that extreme heatwaves affecting Europe in recent years are largely linked to cleaner air, rather than carbon dioxide emissions. Scientists indicate that the reduction of particulate pollution in the atmosphere is a key reason why temperatures on the continent have risen significantly faster than elsewhere globally. Since the 1980s, Europe has warmed by approximately 2.3 degrees Celsius compared to the pre-industrial era, almost twice the global average of around 1.3 degrees. This discrepancy has puzzled experts because warming in Western Europe has exceeded climate models' predictions. Spanish researchers collaborating with the UK Met Office now claim that the main driver behind this additional heat pressure is the decline in aerosol emissions, tiny particles in the air. The Montreal Protocol of 1987, supported by figures like Margaret Thatcher, played a crucial role in reducing these emissions to protect the ozone layer. Aerosols, particularly sulfates, previously acted as a shield, reflecting sunlight back into space and cooling the planet. As their concentrations dropped, more solar energy reached Earth’s surface, altering atmospheric circulation patterns. A
Bias read (Center): The article presents scientific findings without overt ideological framing. It discusses environmental policies such as the Montreal Protocol but does not take a stance on the implications of these policies. The tone remains neutral, focusing on presenting research conclusions and their mechanisms.
