Malnutrition: biggest climate killer

More variable and extreme weather and changing rainfall patterns can reduce the local availability of food in worst affected regions. When those effects take place in impoverished areas where subsistence farming is widespread, people ultimately have less food to eat and malnutrition rates increase. Worldwide the effect of this impact is so significant that it actually accounts for the majority of deaths linked to climate change, or more than 200,000 deaths per year, mainly among children in Africa and South Asia.
