Air pollution can have a cooling effect on the climate

In recent years, there has been a growing concern about the impact of declining air pollution on the climate. Climate scientist James Hansen, famous for his early warnings about global warming, has highlighted the unintended consequences of using aerosols to counteract greenhouse gas warming.
Hansen’s latest research suggests that the reduction in air pollution may be contributing to accelerated global warming. Recent spikes in global temperatures have raised questions about the factors driving this increase.
Hansen and his team believe that a decrease in air pollution, particularly from shipping, has contributed significantly to the recent temperature rise. They estimate that the reduction in aerosols from shipping has led to an increase in the heat reaching Earth, potentially masking the full impact of greenhouse gases.
This new information suggests that the climate may be more sensitive to greenhouse gas emissions than previously thought, emphasizing the need for urgent action to address climate change.
Further research is needed to fully understand the complex relationship between air pollution, aerosols, and global warming.
