Am I the only one that hates the BP time notation? Before Present? To know an absolute date, you have to know the date of 'Present'.

What is wrong with using standard Gregorian dates, or Hebrew years, or something that is NOT a relative measurement. /rant off

Thanks for posting this. I've always been interested in the Younger Dryas era and the following warming.

Do you love the first graph that has wild temperature swings, and there is a teensy weensy blip with an arrow pointed at the present with a label “global warming”? Also, note that the temperature of the little ice age appears to be higher than our current temperature.

Don-It’s true that events like the younger dryas do not appear to be orbitally forced, but good agreement has been shown between the rate of change of global ice volume and the near Arctic circle summer insolation. It is certainly clear that some “spikes” of rapid change exceed what would be expected from Milakovitch alone, but I wouldn’t be so quick to say that the Milankovitch theory of the glaciations is “dead” at all. The long term correlation is quite good. We just need to invoke other factors for some episodes that deviate from the right Milankovitch model.

Very nice, comprehensive thread on the glitch coming out of the Wisconsin Ice Age. Thanks!

The end of the ice age was caused by lizard aliens! They successfully warmed the earth with their advanced technology, augmented by methane from farts.

They could not take advantage of their success however because Obama traveled back in time and drove them off.

from the article: "Both 14C and 10Be production rates in the upper atmosphere changed during the YD.
14C and 10Be are isotopes produced by collision of incoming radiation with atoms in the upper atmosphere.
The change in their production rates means that the Younger Dryas was associated with changes in the amount of radiation entering the Earth’s atmosphere, leading to the intriguing possibility that the YD was caused by solar fluctuations."

So the sun did it?
Not "Ug" Gore, the global warming cave man with his stone-age hockey sticks telling fellow troglodytes they had to stop cutting down trees for fire, and burning fields to catch game?

I always thought it was Ug and his mamma Ob (aka Ob-mamma) who ended stone-age man made global warming, reversed the rising sea levels, thus creating the Garden of Eden in the Persian Gulf... ?

So now after all these years, you tell us Ug Gore and his Ob-mamma have been getting credit they didn't deserve?
Well, then shhhhhhhhhh... don't tell anybody else.
