Global Warming could make Humans EXTINCT within 50 years
Kill mechanisms list
Global Warming could make the human race EXTINCT. The #1 kill mechanism is famine. See "The Long Summer" by Brian Fagan and "Collapse" by Jared Diamond. Shifting winds and warmer oceans have already created a weird moving checkerboard of drought and flood that has interfered with agriculture here and elsewhere.
The extra heat has caused heat related deaths already.
The book "Six Degrees" by Mark Lynas says: "If the global warming is 6 degrees centigrade, we humans go extinct." The book lists several kill mechanisms, the most important being famine and methane fuel-air explosions. Other mechanisms include fire storms.
"Under a Green Sky" by Peter D. Ward, Ph.D., 2007 says H2S bubbling out of hot oceans is the final blow at 6 degrees C warming.
"Climate Code Red" by David Spratt and Philip Sutton says the following: Long term warming, counting feedbacks, is at least twice the short term warming. 560 ppm CO2 gets us 6 degrees C or 10.8 degrees F. We will hit 560 ppm before mid century.
Per "Climate Code Red", we need ZERO "Kyoto gas" emissions RIGHT NOW and we also need geo-engineering because we have already gone way beyond the safe CO2 level of 300 to 325 ppm. We are already at 455 ppm equivalent [including greenhouse gasses other than CO2] and we have tripped some very big tipping points. We aren't dead yet, but the planet needs critical intensive care if we humans are to have a chance of survival.
"Storms of My Grandchildren" by James Hansen, chief of NASA-GISS paints the bleakest picture: Earth goes Venus, becoming a completely dead hot rock at 800 degrees F and our Mars colonies cannot survive because Mars has been a dead planet for too long.
"The Vanishing Face of Gaia" by James Lovelock has identified a 9 degree lurch in the temperature that happens at 450 ppm equivalent. Others have said that methane hydrates released from the ocean floor can make a 9 degree lurch, but not so soon. Looks like we are not going to make it. We HUMANS could be EXTINCT by 2050 because politicians are not considering sufficiently strong action.
