Scientists Say Recent U.S. Heat Wave Would Be ‘Virtually Impossible’ Without Climate Change

A recent heat wave swept across large parts of the United States. Scientists examined the atmospheric conditions that produced the extreme temperatures. They concluded that such a heat event would be virtually impossible in a pre‑industrial climate. The researchers attribute the shift to a climate that is fundamentally different today. Rapid fossil fuel consumption has accelerated global warming. The altered climate increases the likelihood of severe heat extremes. Experts warn that similar events may become more common as warming continues. The findings highlight the direct link between human emissions and extreme weather.
