Time for a reality check. It has been the slowest July Arctic melt in the eight year JAXA record<http://www.ijis.iarc.uaf.edu/seaice/extent/plot.csv> .
<http://climateinsiders.files.wordpress.com/2010/07/jaxa_july_1-17_ice_melt.png> Ice extent has declined at less than half the rate of 2007, and total ice loss has been more than 200,000 km² less than the previous low in 2004. DMI <http://ocean.dmi.dk/arctic/icecover.uk.php>now shows Arctic ice extent as second highest for the date, topped only by 2005. <http://climateinsiders.files.wordpress.com/2010/07/icecover_2010-21.png> Closeup below. <http://climateinsiders.files.wordpress.com/2010/07/dmicloseup4.jpg> Cryosphere Today shows that ice extent and concentration is about the same<http://igloo.atmos.uiuc.edu/cgi-bin/test/print.sh?fm=07&fd=15&fy=1990&sm=07&sd=15&sy=2010> as it was 20 years ago. <http://climateinsiders.files.wordpress.com/2010/07/uiucjuly152010vsjuly151990.jpg> The modified NSIDC map below shows in green, areas where ice is present in 2010 but was not present in 2007. <http://climateinsiders.files.wordpress.com/2010/07/nsidcjuly162007vsjuly162010.jpg> The modified NSIDC map below shows (in red) ice loss over the last week. Note that ice extent has increased slightly in the Chukchi and Beaufort Seas, while it has declined slightly in the East Siberian Sea. <http://climateinsiders.files.wordpress.com/2010/07/nsidcarcticicelossjuly09-july162010.jpg> The modified NSIDC map below shows the record low ice loss since the first of the month. <http://climateinsiders.files.wordpress.com/2010/07/nsidcarcticicelossjuly01-july162010.jpg> The modified NSIDC map below shows ice loss since early April. <http://climateinsiders.files.wordpress.com/2010/07/nsidcapril052010vsjuly1620101.jpg> The graph below shows PIPS ice thickness over the last five years. Average ice thickness in 2010 continues to track a little below 2006. It should bottom out in the next week or so between 2006 and 2009. <http://climateinsiders.files.wordpress.com/2010/07/pips_ice_average_thickness_metres3.png> The low ice loss is consistent with the low Arctic temperatures<http://ocean.dmi.dk/arctic/meant80n.uk.php> we have seen this summer. <http://climateinsiders.files.wordpress.com/2010/07/meant_2010-51.png> The North Pole webcam below<http://psc.apl.washington.edu/northpole/webphotos/noaa1.jpg> shows that the meltponds are frozen over. Temperatures have been below -5°C this week <http://psc.apl.washington.edu/northpole/POPS13_atmos_recent.html>. Very cold for July. <http://climateinsiders.files.wordpress.com/2010/07/noaa1-1.jpg> David Schnare -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
