They say in this article that we have not witnessed global cooling which is not entirely true. The problem with how surface temperature readings have been collected and analyzed leaves open a huge possibility for error and misinterpretation.
Here is a great site that all who are interested should check out:
Except that even with lousy [deeply flawed] surface temperature collection [with collection stations clustered near man-made hotspots], we STILL know that temperatues peaked way back in 1998, and have been declining since then.
Right now, we're in the middle of the coldest winter [and spring] in decades.
