<div>Some may recall the discussion in June 2010 on Vision2020 regarding Anthony Watts' junk climate science blog "Wattsupwiththat" regarding his assertion early in the 2010 season, on April 29, 2010, that "the indications are that we’ll have another summer extent that is higher than the previous year, for the third year in a row." ( <a href="http://wattsupwiththat.com/2010/04/29/another-arctic-sea-ice-milestone/">http://wattsupwiththat.com/2010/04/29/another-arctic-sea-ice-milestone/</a> ).</div>

<div>In the middle of Sept. 2010 the Arctic sea ice extent appeared to have reached its lowest point of the season, and was increasing, then started to decrease to a point below the earlier assumed lowest extent, coming very close to the 2008 second lowest extent. The 2010 Arctic sea ice extent low point was well below the low point for the 2009 season, the previous third lowest extent on record, now the fourth lowest, replaced by the 2010 sea ice extent as the third lowest; therefore Anthony Watts prediction has not come true. Read the information on the Arctic sea ice extent 2010 season at these websites from the National Snow Ice Data Center: <a href="http://nsidc.org/arcticseaicenews/index.html">http://nsidc.org/arcticseaicenews/index.html</a> <a href="http://nsidc.org/images/arcticseaicenews/20101004_Figure2.png">http://nsidc.org/images/arcticseaicenews/20101004_Figure2.png</a></div>

<div>Below is an excerpt from a Vision2020 post I sent that mentions the Anthony Watts' commentary on Arctic sea ice extent, from April 2010, mentioned above. The full post is at this website:</div>

<div>Sun, Jun 27, 2010 at 3:04 PM<br>subject: National Snow Ice Data Center: Arctic Sea Ice Decline During June Continues Below Record 2007 Low Extent<br></div>
<div>During June 2010, Arctic sea ice decline has continued at a pace below the record low 2007 year ( <a href="http://nsidc.org/arcticseaicenews/">http://nsidc.org/arcticseaicenews/</a> , <a href="http://nsidc.org/data/seaice_index/images/daily_images/N_stddev_timeseries.png">http://nsidc.org/data/seaice_index/images/daily_images/N_stddev_timeseries.png</a> ). <br>
<br>The data on Arctic sea ice extent is updated daily on the NSIDC website, with a one day lag. Of course, this trend could change so that 2010 does not exceed the 2007 record low Arctic sea ice extent. Note this is not a discussion of ice volume, or thickness.<br>
<br>Arctic sea ice extent is now on June 27 more below the record 2007 rate of decline than it was May 31, 2010. So much for the Arctic sea ice extent "recovery" promoted by some climate change skeptics confirmation bias filtered websites ( <a href="http://wattsupwiththat.com/2010/04/29/another-arctic-sea-ice-milestone/">http://wattsupwiththat.com/2010/04/29/another-arctic-sea-ice-milestone/</a> ) as evidence to question the seriousness of anthropogenic climate warming. </div>
