[Vision2020] Slanted Media Reporting: "Conservative" IPCC Understates Rate of Arctic Sea Ice Decline, Sea Level Rise, Temperature Increases

[Ted Moffett]

 There are a number of climate scientists who believe that the IPCC
(Intergovernmental Panel on Climate Change) in significant ways *understates
*some potential impacts of climate change.

Why are these IPCC alleged underestimations of climate change not currently
reported widely in the media, to provide balanced reporting in light of the
current widely reported criticisms of IPCC error(s), that are claimed to
exaggerate impacts of climate change?

The rate of Arctic sea ice decline is faster than the IPCC predicted, which
supports the claims of some that the climate models the IPCC uses are
faulty; but the error in this case is not toward exaggerating global
warming, but towards underestimating it:

PRESS RELEASE: Models Underestimate Loss of Arctic Sea Ice

Arctic sea ice is melting at a significantly faster rate than projected by
the most advanced computer models, a new study concludes (see Figure
1<http://nsidc.org/news/press/20070430_StroeveGRL.html#fig1>).


Scientists at the National Snow and Ice Data Center (NSIDC) and the National
Center for Atmospheric Research (NCAR) found that satellite and other
observations show the Arctic ice cover is retreating more rapidly than
estimated by any of the eighteen computer models used by the
Intergovernmental Panel on Climate Change (IPCC) in preparing its 2007
assessments.

NASA climate scientist James Hansen's analysis March 2007 asserts the IPCC
understates the potential for sea level rise in the following article:

>From "Scientific American," April 2007, read about the "conservative" work
of the IPCC, that may "underestimate the changes," that left out a reference
to "an accelerated trend in this warming."

>From website above:

The summary describes the existence of global
warming<http://www.scientificamerican.com/topic.cfm?id=global-warming-and-climate-change>as
"unequivocal" but leaves out a reference to an accelerated trend in
this
warming. By excluding statements that provoked disagreement and adhering
strictly to data published in peer-reviewed journals, the IPCC has generated
a conservative document that may underestimate the changes that will result
from a warming world, much as its 2001 report did.
