The name is Bond...Gerard Bond. Posted on 12 March 2011 by Rob
Honeycutt One of the main climate skeptic claims when presenting
the Greenland Ice Sheet Project 2 (GISP2) record is that climate
change during the Holocene is normal, that there is nothing new
about the warming we see today. This is not a claim that is
substantiated by the full body of research. We're going to take
out a "license to kill" this particular skeptic meme. The name
is Bond...Gerard Bond. Specifically, Bond et al 1997 titled A
Pervasive Millennial-Scale Cycle in North Atlantic Holocene and
Glacial Climates. Okay, this Bond doesn't quite have Ian
Fleming's knack for a catchy titles but we'll work with it. Many
of you may be familiar with Dansgaard-Oeschger (D-O) events.
These are the rapid climate change events we see in the ice core
data during glacial periods. They are easily recognizable in the
GISP2 core by rapid warming followed by slower cooling,
following an aproximately 1470 year cycle. D-O events are also
notable in the climate
