The World Health Organization calls climate change “the single biggest health threat facing humanity.” That’s strong language! They estimate it could cause around 250,000 extra deaths per year between 2030 and 2050, from things like malnutrition, malaria, diarrhea, and heat stress. Those are slow, preventable problems getting worse.
The term WHO uses that stuck with me is “threat multiplier.” Climate change doesn’t usually invent brand new diseases out of nowhere. Instead it takes the health problems we already have and makes them worse. Hotter weather means more heat illness. Shifting rain and temperature patterns let mosquitoes spread diseases like malaria and dengue. Floods and droughts mess with food and clean water.
