Climate change is a threat to health

It has a profound effect on health, as rising temperatures can facilitate the emergence and spread of drug-resistant pathogens.

It is widely believed that climate change is the single biggest threat to human health. A global temperature increase of 2° Celsius—a threshold that will likely be exceeded by the end of the century—could claim as many as one billion lives, with extreme weather events, heatwaves, droughts, flooding, infectious disease outbreaks, and food shortages among the causes of death. But the situation may in fact be far worse because the current forecasts fail to account for the inevitable increase in antimicrobial resistance (AMR).
