Yep, another Little Ice Age would endanger a lot of animals. You do know they expect the current Global Cooling to last until at least 2050, don't you? Oh, I know, you think Climate Change means Global Warming but the Earth has not increased in temperature since 1997 and since 2007 has actually cooled."Climate change alone is expected to threaten with extinction approximately one quarter or more of all species on land by the year 2050."

Oh, Urban Heat Islands (big cities) account for less than a half of one percent of the Earth!!!
