World Health Organisation, WHO says, Climate change is likely to cause over 2 lakhs 50 thousand additional deaths per year between 2030 and 2050.
It said, these deaths will be caused due to malnutrition, malaria, diarrhoea and heat stress.
The WHO said, by the late 21st century, climate change is expected to increase the frequency and intensity of drought at regional and global scale.
It said, rising temperatures and variable precipitation are likely to decrease the production of staple foods in many of the poorest regions of the world.
This will increase the prevalence of malnutrition and under-nutrition, which currently cause 3.1 million deaths every year.
However it said, climate change may cause fewer winter deaths in temperate climates and increase food production in certain areas.
