A study commissioned by 20 developing countries is warning more than 100 million people will die by 2030 if the world fails to take on global warming. The Climate Vulnerable Forum says air pollution, hunger and disease caused by climate change and the consumption of fossil fuels will kill five million people per year. More than 90 percent of the estimated deaths would occur in developing countries. The report also warns global warming threatens to seriously contract the global economy over the next decade.
