For how we live.
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%.
More than 2,700 people died in England and Wales during the May and June heatwaves. An attribution study assigns roughly 42% of those deaths to warming.
Maricopa County runs some of the most detailed heat mortality surveillance in the US. A distributed lag model applied to the same five years put the toll far higher — and the gap is the method, not a scandal.
An analysis of global temperature data from 1950 to 2024 finds the share of the world's population facing dangerous heat-stress days has climbed sharply since the 1970s, summarized this month in JAMA.
As the 2026 World Cup opens, researchers point to last year's Club World Cup as a preview: 31 of 57 matches were played at heat levels guidelines say should have stopped play.
A global estimate across 8,919 urban areas finds both numbers are true at once — and that the cooling lands hardest in the places that need it least.
An analysis of nearly 30 years of confirmed heat deaths finds many occurred well under standard alert thresholds, and that humidity-based measures may track risk more consistently.
A meta-analysis spanning two decades of research found extreme cold carried a higher relative risk of death than extreme heat or heatwaves — even as warming shifts public attention toward summer temperatures.
A 14-year national analysis finds temperature-related death rates rising fastest in the group that started highest — and the same pattern in cold deaths, which fell for everyone else.
A rapid attribution study finds human-caused warming made this month's record Southwest heat wave far more likely, and doctors warn the early timing caught people unacclimatized.
Play was suspended on outside courts on Saturday when the tournament's five-point Heat Stress Scale maxed out. A ball kid collapsed during a match the same day. The threshold is set on physiology, not air temperature.
Across 11 surveillance sites in sub-Saharan Africa, nighttime heatwave mortality risk rose between 2005-2010 and 2011-2015 — the opposite of the adaptation trend reported in wealthy countries.
The 2025 Lancet Countdown Latin America report tracks 41 indicators across 17 countries. Heat-related deaths are up 103%, and fewer than half the region's governments have finished a vulnerability assessment.
A 43-year analysis at hourly resolution finds a 3.3% rise in average heat stress exposure duration across districts, with the change varying by time of day, season and region.
Researchers tested heat-mortality forecasts against the European summers of 2022 and 2023. The skill pattern is not the one a warning system designer would have guessed.
A 47-prefecture analysis of a decade of heatstroke mortality finds the alert level set at 33C misses almost all of the deaths a warning could plausibly prevent. About 31C would halve them.
