somehow I lost the word "AGES" at the end of the title above. Sorry.

Good report, thanks. More support for the Milankovitch theory, which I believe.

Bump.

Good find.

Like evidence from cores below the seafloor in the North Atlantic, these segments suggest a transition from intense glaciations to a wide-scale glacial retreat may have taken less than 100 years.

"It should catch people's attention now since the change appears to occur in about a human lifespan," Krissek said.

This guy just signed his professional suicide note. What he is suggesting here is that rapidly retreating glaciers have occurred repeatedly throughout our geological history, and therefore are not indicative of any human influence on the atmosphere.

Grants will be pulled, he’ll be ostracized by his peers, his work will be trashed as junk science, and a grad student will accuse him of sexual harassment.

He’ll be bartending to pay his mounting legal bills by the (“warmer than normal due to US industry”) spring.

Some more information on Milankovitch cycles:

Milankovitch Cycles and Glaciation

The episodic nature of the Earth's glacial and interglacial periods within the present Ice Age (the last couple of million years) have been caused primarily by cyclical changes in the Earth's circumnavigation of the Sun. Variations in the Earth's eccentricity, axial tilt, and precession comprise the three dominant cycles, collectively known as the Milankovitch Cycles for Milutin Milankovitch, the Serbian astronomer who is generally credited with calculating their magnitude. Taken in unison, variations in these three cycles creates alterations in the seasonality of solar radiation reaching the Earth's surface. These times of increased or decreased solar radiation directly influence the Earth's climate system, thus impacting the advance and retreat of Earth's glaciers.

It is of primary importance to explain that climate change, and subsequent periods of glaciation, resulting from the following three variables is not due to the total amount of solar energy reaching Earth. The three Milankovitch Cycles impact the seasonality and location of solar energy around the Earth, thus impacting contrasts between the seasons.
