Global warming and Climatic change impacts.
What is Global warming ? Increased GHG Less heat escapes into space More re emitted heat Temperature rise.
F•gases 2% Nitrous Oxide 6% Methane Carbon Dioxide (forestry and other land use) 11% Carbon Dioxide (fossil fuel and industrial prcxesses) 65%.

Human health. - Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter - Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress - The direct damage costs to health (i.e. excluding costs in health-determining sectors such as agriculture and water and sanitation), is estimated to be between USD 2-4 billion/year by 2030 - Areas with weak health infrastructure – mostly in developing countries – will be the least able to cope without assistance to prepare and respond - Reducing emissions of greenhouse gases through better transport, food and energy-use choices can result in improved health, particularly through reduced air pollution.
Solutions. Renewable energies : Changing our main energy sources to clean and renewable energy. Solar, Wind, Geothermal and biomass could be the solution..
