Field studying how climate change affects human health, including heat-related illness, infectious disease spread, nutrition, and chronic conditions.
Global Climate and Health Alliance scorecard of 132 countries says the EU, China, Brazil and the UK mention health but lack the targets to protect it. Only five countries set black carbon targets, the alliance says.
Reality
Los Angeles County has logged more than 180 West Nile cases this year, its most in nearly a decade, county health figures show. A local vector-control official links the rise to a warm year, a plausible cause that one season of figures can show only as a correlation.
Reality
Lancet Commission experts rank malicious AI use, including bioweapons, alongside nuclear war as the threats that could end humanity by 2100. Their report says each of its 17 risks has a realistic route to action, so AI misuse reaches policymakers as a problem with a solution.
Reality
Florida has 252 locally caught dengue cases this year, more than five times any of the prior four years at this date, a University of Florida researcher said. Hillsborough County, around Tampa, accounts for 223 of them, so most of the jump is one county's outbreak, far north of the Miami-area clusters Florida sees every year.
Reality
University of Bristol researchers set out five steps in The Lancet to protect health from a super El Niño expected late this year. Most of the steps ask for evidence first, because the extra health burden El Niño adds to climate change is still largely unmeasured.
Reality
Natural History Museum and Oxford researchers matched the timing of more than 6,000 Nigerian Lassa cases using rainfall and nearly 30 years of rodent data. Because the model runs on weather and rodent ecology, health authorities could use it to anticipate when the risk of spillover to people climbs each season.

Sustentarea at the University of Sao Paulo mapped under-5 stunting and overweight against per capita emissions for Brazilian municipalities from 2008 to 2019. It shows where the problems overlap, though local emissions cannot test the climate-to-diet chain said to link them.
Reality
Writing in Nature Human Behaviour, a Heidelberg group argues that health inequity is produced outside health systems, and asks climate planners to state in advance which groups each measure helps and which it leaves worse off.
Reality
The Annenberg Public Policy Center surveyed 1,904 adults in early August and found the health-attribution figure level with 2024 and 2025, while knowledge of where to find a cooling center sat where it did a year ago.
Reality
The World Health Organization counts one in six infections as drug resistant, and a growing body of research argues that heat and chemical stress help resistance genes persist and travel. The size of that contribution is still unmeasured.
Reality
Stanford researchers are coating informal-settlement roofs in Indonesia to cut indoor heat by up to 5F. The defence offered is physiological rather than comfort, and the cost is still unpriced.
