UN climate report: 'Atlas of human suffering' worse, bigger

Deadly with extreme weather now, climate change is about to get so much worse. It is likely going to make the world sicker, hungrier, poorer, gloomier and way more dangerous in the next 18 years with an "unavoidable" increase in risks, a new United Nations science report says.

And after that watch out.

The UN Intergovernmental Panel on Climate Change report said Monday if human-caused global warming isn't limited to just another couple tenths of a degree, an Earth now struck regularly by deadly heat, fires, floods and drought in future decades will degrade in 127 ways with some being "potentially irreversible."

"The cumulative scientific evidence is unequivocal: Climate change is a threat to human well-being and planetary health," says the major report designed to guide world leaders in their efforts to curb climate change. Delaying cuts in heat-trapping carbon emissions and waiting on adapting to warming's impacts, it warns, "will miss a brief and rapidly closing window of opportunity to secure a liveable and sustainable future for all."

Today's children who may still be alive in the year 2100 are going to experience four times more climate extremes than they do now even with only a few more tenths of a degree of warming over today's heat. But if temperatures increase nearly 2 more degrees Celsius from now (3.4 degrees Fahrenheit) they would feel five times the floods, storms, drought and heat waves, according to the collection of scientists at the IPCC.
