Read around in it, and it is complete fruitcake insanity. This was after I realized the omission of overpopulation as a cause and when intelligent life from the universe is supposed to come and help was written.
http://www.wunderground.com/climate/PETM.asp?MR=1Good site for some reference in Fig 2; Current 30+ billion tons per year of carbon, PETM 2+ BTY. (15 times as much, before CH4 self release point, then increasing vastly)
Temperature rise to PETM level which took 17K yrs. in less than 1K yrs. (then much more at 1 to 1.5K years)
Then in Table 1; PETM Rate of Warming .025*C per 100 yrs. and now 1 to 4*C per 100 years.(present temperature rise 40 times PETM, increasing to 160 times PETM)
Causes; PETM geologic vulcanism, CO2 to CH4 hydrates releases, probable seismic mechanic mass release of CH4 hydrate.
AETM; Human fossil fuel burning and slash and burn mass agriculture to feed overpopulation, leading to CH4 hydrates self release.
From other sources PETM had a 30% extinction and AETM will have up to a 90% extinction because of the time differential and life's ability with time to adapt, and not to adapt with too little time of AETM.
The total carbon in the form of CH4 hydrates is more than PETM, lower starting temperature, also, and will lead to a much larger temperature rise as PETM, with longer sequestration time(150-180K yrs. PETM, 200K+ yrs. AETM) and much longer time to regain species diversity(2 million years PETM, 3 million+ years AETM)
Note use of new term from the change to Anthropocene Epoch terminology.
Possibilities of change; early population crash to stop 90% of emissions before 2020 from huge volcanic eruption which also keeps aerosols in atmosphere for many years, or worse, a nuclear war which does similar. There is one Icelandic volcano that is due that might possibly do it. Keep several years of food supplies with protection, and pray for this.
Change for even worse would be a partial population crash which allows more fossil fuels to be burned until most depleted, and progression to runaway greenhouse effect. Pray for this not to happen.
Economic depression and several due geologic events, La Palma and Cascadia, could do this, and are due.
Another more remote possibility is Yellowstone super eruption coming early(within 300 years or so), which could restore the Ice Age/Interglacial cycle. If it happens in 2K+ years as is probable, it will not cool down the biosphere enough because thermageddon will be well established.
Another remote possibility is a meteorite strike large enough to do similar aerosols.
Hansen told us how to deal with AGW back in his TV Special in 2006. A 90% reduction in fossil fuel use within a decade.
In his book, "Storms of My Grandchildren" he said to immediately replace most coal fired power plants with Gen IV nuclear and the rest of our energy needs with solar, wind, and various hydro power. He also said population reduction is absolutely necessary to not only reduce energy demand, but depletion and other pollution.
So the answers have been out there a long time, and only selfish stupidity has kept them from being implemented in time.
If you read about the end results of insufficient action, there is no ability to adapt for the length of time thermageddon will affect the biosphere.
I suppose you can pray for an act of God type geological event, or prepare yourself spiritually for near future man caused calamities and death, like in the book by the Boulder semi-informed minister........
We went to a one child only family in 1988, joined NPG and read the solar living sourcebook and earthship in 1993, spiritual awakening 1996 with AA, self built solar house and Earthship 1997-2000, composters and 3 Rs, good mileage cars since 1978 and hybrid since 2009. 2 years supply of food. well water and back up systems and defense weapons. If everyone did what I did when I did it, the world would have peaked in population and gone down along with pollution and depletion. There would be no mass die off ahead before mid century and no AETM thermageddon ELE ahead.
