Climate & Earthquakes II

Part II[wpcol_1half id=”” class=”” style=””]Dunkley Jones et al. support the view that, while gas-hydrate release was probably not responsible for an initial, rapid, CO2-driven warming, the as yet unknown event responsible for this subsequently triggered the large-scale dissociation of gas hydrates, which contributed to further warming as a positive feedback mechanism. As the authors note,…

3.5 mil years ago, summer temps were ~8°C warmer than today, CO2 was ~400 ppm

Two recent studies on past temperatures… Pliocene Warmth, Polar Amplification, and Stepped Pleistocene Cooling Recorded in NE Arctic Russia Understanding the evolution of Arctic polar climate from the protracted warmth of the middle Pliocene into the earliest glacial cycles in the Northern Hemisphere has been hindered by the lack of continuous, highly resolved Arctic time…

The 8 Minute Epoch 65 million Years with James Hansen

In a speech at the University of Oregon, James Hansen, NASA’s chief atmospheric scientist, walks listeners thru the most recent geologic periods, and speaks to the commonly heard climate canard, “It’s been hotter in earth’s history before – so what’s the big deal?’ this presentation and others by Hansen available here: http://www.columbia.edu/~jeh1/present… James Hansen’s original…
