Arctic sea ice update: 2,300 Manhattans more than last year

Arctic Sea Ice News & Analysis
Average ice extent for June 2011 was 11.01 million square kilometers (4.25 million square miles). This is 140,000 square kilometers (54,000 square miles) above the previous record low for the month, set in June 2010

Might be informative to mention that it ranks as the 2nd lowest in recorded history - behind only 2010. And that at current rates of loss it should pass 2010 within a week.

Just to be more informative, does your "recorded history" start closer to the building of the pyramids, or to the "Happy Days" debut of TV's "The Fonz"?

Are you trying to mislead people?

Will there be an update when this year's sea ice extent goes a couple of thousands of Manhattans below that of 2010?

Neven, lets change one word and see if the statement is still true:

Are you trying to mislead people?

Yep, still true. Not much of an argument then is it?

Nice try, but:

1) Arctic sea ice volume -- the most important metric -- is at a record low, and the trend is amazing:

2) The latest data now shows 2011 ice extent is the lowest ever for this date:

Wrong again David: http://stevengoddard.wordpress.com/2011/07/07/thick-ice-area-has-more-than-doubled-since-2008-2/

1. Goddard is wrong about so many things on such a regular basis that I don't believe a thing he writes.

2. A blog post is hardly equivalent to peer-reviewed methodology.

3. Goddard's post, to the extent it can be trusted at all, refers to ice area, not volume, and to ice greater than a certain thickness, not all ice. It therefore says nothing about the sum total of Arctic sea ice.

Arctic ice volumn]e versus area? I find this hair splitting rather dubious. While satellite photography can surely be measured reliably, can volume?

Call me unsophisticated, but I am dubious that aerial measurements of volume mean much of anything.
