He is decidedly one-sided in his views and because of that one should always assume that he intentionally omits important information.

His interest in the linked paper was clearly focused upon the climatic conditions that may have led to floral and faunal changes in Beringia after the last cold spell 11-12K years ago. <br /><br />Earlier I've mentioned solar input, as measured via a specific meter, or solar panel, as a driver of both weather and climate. Some have linked the PDO and Solar Cycles. And as you note, other factors like albedo, moisture, Skew-T values, wind at various levels, on and on likely all contribute. <br /><br />Thanks for the new hypothesis. I'll crawl around in that tomorrow over coffee: <br /><br />https://dl.dropboxusercontent.com/u/51188502/PLA22068.pdf<br />http://www.sott.net/article/265873-Svensmarks-cosmic-ray-theory-of-clouds-and-global-warming-looks-to-be-confirmed<br /><br />Gary<br />NL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-5408822240986912402013-10-02T16:55:00.056-08:002013-10-02T16:55:00.056-08:00Gary,

I like the idea that cloud cover in and of itself is a profound driver of climate variations, and I can't help but think of the Svensmark cosmic ray hypothesis. Cloud cover on a synoptic time/spatial scale obviously brings first-order effects to weather variations, but as you say it seems difficult to separate cloud effects from other highly correlated variables.<br /><br />Richard<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-57817337662641048572013-09-30T22:00:59.481-08:002013-09-30T22:00:59.481-08:00Is it the chicken or the egg?

The ESRL monthly composites show that 2013 had more northerly winds in the mid levels over the NE half of the state in 2013 compared to 2012 and therefore cooler temperatures. Rick would be a better source on this though.Climatologist49https://www.blogger.com/profile/04560505931210357679noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-11116503611844115222013-09-30T19:58:58.316-08:002013-09-30T19:58:58.316-08:00Two thoughts in a row and a question for this Blog...Two thoughts in a row and a question for this Blog. What's the inferred effect of cloud cover on temperature for the above period? <br /><br />During 2013 was cloud cover associated with abnormal temps (both below and above normal?), or was it more likely associated with upper air flow patterns and systems?<br /><br />Not a work assignment, just food for thought brought upon by a hypothesis from a recently read archaeological paper: <br /><br />http://www.seas.harvard.edu/climate/seminars/pdfs/Guthrie_2001.pdf<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-73915612825899938172013-09-28T20:29:22.920-08:002013-09-28T20:29:22.920-08:00The Columbia River saw the larget run of Chinooks ...The Columbia River saw the larget run of Chinooks in 75 years (http://goo.gl/RwbdZv).

Here's another perspective from a salmon's point of view. They occupy the north pacific gyre influenced by the PDO:<br /><br />http://www.nwfsc.noaa.gov/research/divisions/fe/estuarine/oeip/ca-pdo.cfm<br /><br />Note that as NW US salmon prosper in a cold PDO, Alaskan stocks suffer. Studies are undergoing to determine the cause.<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.com
