![]() ![]() We can ignore the warning signs and pollute ourselves into what Schmidt envisions as a "vastly different planet" – roughly as different as our current climate is from the most recent ice age. Right now, humanity is standing on a precipice. More extreme storm surges, wildfires, and heat waves are on the menu for 2070 and beyond. ![]() If the extreme El Niño event of 2015 to 2016 was any indication, we're in for much more dramatic natural disasters. If unchecked, climate change could cause severe drought across 40 percent of all land, double what it is today.Īnd then there's the weather. In a 2013 paper, scientists used models to estimate that the world could see more severe droughts more frequently – about a 10 percent increase. In the temperate zones, 30 percent or more of the days will be what is now unusual.Įven a little bit of warming will strain water resources. Farther north, 10 percent to 20 percent of the days in a year will be hotter.īut compare that with the business-as-usual scenario, in which the tropics will stay at unusually hot temperatures all summer long. Even if we curb emissions, summers in the tropics could increase their extreme-heat days by half after 2050.

If climate change continues unabated, nearly all coral reef habitats could be devastated. ![]()
