ENSO, Air Temperature and Sea-Ice

Posted: November 18, 2010 in Rebuttals, Uncategorized

I would like to introduce you to
Steven Goddard

He runs the blog http://stevengoddard.wordpress.com/ and he is a very ambivalent climate skeptic who was a well-followed contributor at Anthony Watt’s skeptic website http://wattsupwiththat.com/ .

He is an engineer by trade and seems to have a tendency towards using visually “appealing” graphical arts massaging of figures to demonstrate his climate related points.

Recently he compared annual arctic sea-ice minimums to the PDO and 5-year running means of the El Nino Southern Oscillation (ENSO) in order to explain changes in Arctic sea ice over this period.

I have many concerns with his analysis from a mechanism point of view but I think it is first necessary to try and figure out where this 5-year running mean of ENSO association comes.

It seems based upon this blog and previous work that he believes ENSO variations are the primary cause of global warming and thereby arctic ice loss.

Lets see how this theory holds up.


Doesn’t seem to hold much weight does it? I mean especially post-2000s where there is a clear divergence between the MEI and Global temperatures. I think it would be best to make it a little more clear for him though about the origins of Arctic Sea-Ice losses.

Maybe another way of illustrating this could be effective. Using the “5-year means” that Goddard seems to love.


PS: You should never compare a 5-year running mean to a 1-year mean such as in his ENSO to sea ice post. Just a thought…
