For how we live.
Italy logged 296 locally acquired cases in 2024, a European record. Transmission rose 19.8% per 1°C of warming, and modelling puts most of France in range for the mosquito that carries it this century.

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 study of 5,459 municipalities projects annual costs of $228-264 million by mid-century, with the largest absolute burden in the South and the fastest relative growth in the North.
Deaths during combined heat and ozone days in Hong Kong, preterm births projected across Chinese cities to 2100, and a seasonal flip in Japan's ambulance demand from winter to summer.
