Climate-health mortality attribution.
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%.
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 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 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.
February in Cortina has warmed 3.6°C since it last hosted in 1956. The health question in a warming winter is not comfort — it is unstable snow, artificial surfaces and where sport can safely be held.
WMO puts 2025 at 1.44°C above pre-industrial, second or third warmest depending on the dataset. The 2023–2025 mean of 1.48°C is the figure that describes exposure.
Emergency restrictions came into force on 13 December when the index passed 450. The more telling number is how many days the city has now spent in a category that was meant to be exceptional.
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.
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.
One projects 71,420 US deaths a year from wildfire smoke by 2050. The other projects 1.4 million globally by the end of the century, with Africa's burden rising elevenfold. Both rest on modelled chains, not observations.
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 nine-year case time-series across every municipality finds both ends of the temperature range raise mortality risk on a Caribbean island, with the burden spread unevenly across towns.
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.
About 1,009 deaths a year were attributable to heatwaves in 2016-2019. Queensland and New South Wales carried rates more than three times Western Australia's.
The causes recorded do not look like a textbook heat event: nonspecific findings, nervous system disease and mental disorders led the excess, and deaths at home rose 64%.
