Are we sure there is not anything there? I mean, I know there was quite a temperature surge from 1300-1400 A.D. which must have been solar. Correct? <em>Editor's note: We have been carefully monitoring solar output since the late 1970’s. The bottom line: there has not been an appreciable net change in the energy emitted by the sun and it can not explain the warming we have experienced (<a target="_blank" title="Solar activity and global warming" href="http://www.environmentaldefense.org/documents/5544_SolarActivity_One-pager.pdf">more on solar activity [PDF]</a>). </em> I haven't heard anything about a correlation to solar activity?

This could certainly just be a fluctuation of local temperature. But the following evidence should convince us more about its warming trend: Beijing has had 20 "warm winters"-- where average December to February temperatures are at least 0.5 degrees Celsius higher than the average-- in a row since 1986. http://news.xinhuanet.com/english/2007-02/06/content_5705969.htm Beijing's temperature surged to 16 Celsius on Monday, Feb. 5, 2007, the highest temperature at this time of year for the past 167 years.
