For how we live.
A detection-and-attribution study across 60 pollen stations found seasons 20 days longer and concentrations 21% higher since 1990 — and separated how much of that trend is anthropogenic.
Two papers landed the same day. An attribution analysis puts children aged 0–9 at roughly three times the added humid-heat exposure of people in their sixties; a German cohort counts the emergency visits.
Researchers modelled 854 European cities under the climate that exists and the one that would have existed without human warming. The attributable share rose from 45% to 64%.
Synchronous fire weather more than doubled in most regions between 1979 and 2024, and over half the increase is attributed to human-caused climate change. A separate paper prices the smoke.
A 50-year attribution study separates two trends that usually get modelled as one: rising temperatures and a population that has become less likely to die in them.
A pan-tropical analysis links deforestation-driven local warming to about 28,000 heat-related deaths a year, with Southeast Asia carrying the highest rate.
A 55-expert consensus sets out how to attribute health outcomes to climate change. Its sharpest recommendation is against the fraction-of-attributable-risk method that many studies still use.
