Climate Warming Raises Extreme Weather

The update slightly sharpens the framing of the climate impacts, especially by emphasizing that some extreme heat events were effectively impossible before industrial-era warming. It also narrows the hail story with a more specific regional projection for the U.S. Northern Plains and adds a clearer statement that greenhouse gases remain the dominant driver.

The story broadens beyond Europe-centric heat and rain attribution to a wider transatlantic heat-and-hail risk picture, with new emphasis on exceptionally improbable preindustrial heat events in North America and Europe and on future large-hail damage potential. It also reframes the impacts more concretely around health, events, and infrastructure exposure.
