The Intergovernmental Panel on Climate Change (IPCC) is responsible for evaluating the risks of human-caused climate change and gathering prevention and adjustment strategies. It was established by the United Nations Environmental Organisation (UNEO) and the World Meteorological Organisation (WMO). Based on the IPCC’s most recent report from 2013 and wide-ranging scientific analyses, there is a 95% likelihood that global warming in the last 50 years is the result of human activities.
Exponential population and economic growth have increased emissions of CO₂ and other greenhouse gases. The concentration of these greenhouse gases in the Earth’s atmosphere is currently higher than it has been in the last 800,000 years (current methods cannot measure further than 800,000 years).
