Much discussion of the Climategate e-mails has centered on "tricking" tree ring data that may not confirm global warming. What's the divergence of data all about and does it really confirm cooling instead of warming? In other words, tree growth may have slowed because the amount of sunlight reaching trees, which is especially critical to growth at high latitudes, has diminished since the mid-20th century. If global dimming is a major factor in the divergence of the past 50 years, should we expect to see the opposite of divergence — realignment? — now that the skies are cleaner?
D'Arrigo responds: "I think this would be difficult to detect and tease apart due to the many competing factors potentially impacting tree growth – hard to separate this type of effect from other environmental factors but an intriguing possibility."
Elizabeth May read all ten years of hacked emails: please have a look at her blog for her conclusions. She doesn't decide global warming is fake. She concludes that scientists involved were cogitating about problems such as the tree ring issue above ... NOT plotting to deceive the world about climate change.

An independent analysis of the emails, however, show that they did not, in any way, undermine the scientific foundation for our understanding of how and why the climate is changing. Even Hayward acknowledges that "Climate change is a genuine phenomenon, and there is a nontrivial risk of major consequences in the future."I keep wondering who funded the hack.......
