<div>There are a number of climate scientists who believe that the IPCC (Intergovernmental Panel on Climate Change) in significant ways <strong><em>understates </em></strong>some potential impacts of climate change. </div>
<div> </div>
<div>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?</div>
<div> </div>
<div>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:</div>

<p>PRESS RELEASE: Models Underestimate Loss of Arctic Sea Ice</p></div>
<div>
<p>Arctic sea ice is melting at a significantly faster rate than projected by the most advanced computer models, a new study concludes (see <a href="http://nsidc.org/news/press/20070430_StroeveGRL.html#fig1" target="_blank">Figure 1</a>). </p>
<p>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.</p>

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

<div>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."</div>

<div>From website above:</div>
<div> </div>
<div>The summary describes the existence of <a href="http://www.scientificamerican.com/topic.cfm?id=global-warming-and-climate-change" target="_blank"><font color="#0aa1dd">global warming</font></a> 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. </div>
