- Climate change directly contributes to humanitarian emergencies due to heat waves, forest fires, floods, tropical storms and hurricanes, and their scale, frequency and intensity are increasing.
- Research shows that 3.6 billion people already live in areas that are highly vulnerable to climate change. Climate change is expected to cause an estimated 250,000 additional deaths per year between 2030 and 2050, from malnutrition, malaria, diarrhoea and heat stress alone.
- The costs of direct health damage (excluding costs in health-determining sectors such as agriculture and water and sanitation) are estimated at $2-4 billion per year by 2030.
- Areas with weak health infrastructure – mostly in developing countries – will be least able to cope without assistance in preparation and response.
- Reducing greenhouse gas emissions through better transport, food and energy choices can lead to very large health benefits, particularly through reduced air pollution.
