Moderators, I am the author of the above comment that has been moderated "Troll"; the moderation was apparently done on the basis of replying comments. I ask you to check what my comment said, before moderating it as troll.
Here is what the Slashdot summary said.
the paper says, that scientists can claim with near certainty that events like the Texas heat wave last year, the Russian heat wave of 2010 and the European heat wave of 2003 would not have happened without the planetary warming caused by the human release of greenhouse gases.
It ought to be clear from this that the Russian heat wave, in particular, is being blamed on putative global warming. Now, check the three links in my comment to confirm that they do indeed say exactly what my comment claims. The second link requires a password or subscription; here is an alternative link, from the American Geophysical Union (which publishes the journal):
You can confirm that the quote supplied in my comment is taken from that link.
The real trolls are the commenters who claimed that I was misquoting or misrepresenting. My comment is not a troll, and it should be moderated fairly.
I think that it says something about the current global warming debate that an accurate critical comment such as mine is moderated troll while blatantly false criticisms of my comment get moderated up to 5.
