Ocasio-Cortez just latest in 100 years of warnings earth 'doomed' - WND:

“It is becoming obvious that the only authentic climate ‘tipping point’ we can rely is this one: Flashback 2007: New Zealand Scientist on Global Warming: ‘It’s All Going to be a Joke in 5 Years.'” Morano wrote.
“The Boston Globe noted on April 16, 2014: ‘The world now has a rough deadline for action on climate change. Nations need to take aggressive action in the next 15 years to cut carbon emissions, in order to forestall the worst effects of global warming, says the Intergovernmental Panel on Climate Change.'”
Such warnings also were issued in 1982, 1989 and 2000.
“In 2007, U.N. IPCC chief Pachauri declared 2012 as the climate deadline to act or it would be ‘too late,'” Morano reported. “Not to be outdone by the U.N., Former Irish President Mary Robinson weighed in this week, issuing a more generous 20 year tipping point. ‘Former president says we have 20 years to save the world from climate change effects. …Robinson calls for climate agreement by 2015.’ Robinson noted that global leaders have ‘at most two decades to save the world.'”
