A new report by the Global Humanitarian Forum estimates global warming is causing more than 300,000 deaths each year. The report is considered to be the first comprehensive study of the human impact of global warming. The Global Humanitarian Forum is a think tank headed by Kofi Annan, the former United Nations secretary-general. If emissions are not brought under control, within twenty-five years, the organization estimates, 310 million more people will suffer adverse health consequences related to temperature increases, 20 million more people will fall into poverty, and 75 million extra people will be displaced by climate change.
