In the next decade, the effects of a rapidly warming climate could kill 5 million people—as many as live in Singapore or Finland. More than 99 percent of those deaths will likely occur in developing countries, and almost four-fifths are expected to happen in South Asia and sub-Saharan Africa. There could be as many as a million climate-related deaths each year by 2030 if nations don't significantly cut planet-warming emissions, according to a report released Friday.
