World Health Organisation, WHO says, Climate change is likely to cause over 2 lakhs 50 thousand additional deaths per year between 2030 and 2050. <br/><br/>It said, these deaths will be caused due to malnutrition, malaria, diarrhoea and heat stress. <br/><br/>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. <br/><br/>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. <br/><br/>This will increase the prevalence of malnutrition and under-nutrition, which currently cause 3.1 million deaths every year. <br/><br/>However it said, climate change may cause fewer winter deaths in temperate climates and increase food production in certain areas.
