For how we live.
A Chinese birth cohort of 1,278 pairs found higher prenatal temperatures and heatwaves — especially in the second trimester — tracked with higher creatinine and urea in early childhood.
A case-crossover study in Kern County found the odds of coccidioidomycosis were about 12.5% higher in the 90 days after a new well was developed within 5 km of home.
A prospective, quasi-experimental study links the air-quality gains after China's 2013 Clean Air Act to an average 6.6-percentage-point reduction in predicted cardiovascular risk.
Analysing 4,504 German twins, researchers found the pollution–wellbeing link ran mostly between families, not within twin pairs — pointing to shared circumstances as much as the air itself.
A 14-year hourly analysis of the heat index finds a rising trend and a 2025 that set records, with a 'feels-like' temperature reaching 52C as early as 7am on some days.
A study of 806 suspected cases found nearly a quarter were confirmed Crimean-Congo haemorrhagic fever, all the main risk factors tied to livestock handling — as warming expands the range of the ticks that carry it.
Each 1 degree C rise in average maximum wet bulb globe temperature across pregnancy was associated with 64% higher odds of a higher stress category — an association, in one cohort, with no mechanism established.
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.
A 34-million-birth analysis maps how far smoke travels from the fires that make it. A companion review is blunt that what that exposure does, beyond the lungs, is still unsettled.
Two 2026 papers describe the same shift: rural incidence now exceeds urban in some years, the peak has slid to October and November, and one in six hospitalised patients progressed to severe disease.
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.
Researchers built an occupation-by-occupation exposure matrix to identify who's most exposed to climate-related heat on the job — construction workers, men, and Native American workers topped the list.
A 121-country model finds health-system emissions are as unequally distributed as the care itself — and that cutting them may not require cutting care.
A national case-crossover study of 236,260 chronic kidney disease deaths finds women, over-65s and people in cooler regions most affected — and projects the burden nearly quadrupling by the 2090s.
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.
An analysis of insurance claims from 2016 to 2023 found extreme heat consistently drove up emergency department use and cost across commercial, Medicaid, and Medicare Advantage plans.
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.
A new analysis of 198 cities finds 87% have a longer freeze-free growing season than in 1970 — up to 100 extra days in Reno — pushing pollen exposure further into the calendar.
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.
The first national estimate of temperature-attributable food poisoning in Australia. A companion study in Queensland tested whether heat also drives drug resistance in the same bug — and found nothing.
A year of wearable data from 76 subsistence farmers shows adaptation happening in real time. The women in the study had less room to slow down, and their strain readings show it.
Twelve years of English primary care records put a price on weather. The heat effect is loud and short; the cold effect is quiet, cumulative, and much larger.
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.
Berkeley researchers followed older Californians for a decade. Cumulative smoke exposure predicted death better than the number of smoke days did — which is not how air quality is usually reported.
Floods and landslides in Indonesia, Sri Lanka and Thailand have killed more people in a fortnight than most single climate events on record. The second wave — water, food, medicine — is the part that lasts.
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.
