WHO calls on countries to protect health from climate change

Climate change is the defining issue for the 21st century.

According to WHO estimates, climate change is already causing tens of thousands of deaths every year - from shifting patterns of disease, from extreme weather events, such as heat-waves and floods, and from the degradation of air quality, food and water supplies, and sanitation.
