A line-by-line evaluation of the Climate Strategy memo, which the Heartland Institute has repeatedly denounced as a “fake” shows no “obvious and gross misstatements of fact,” as Heartland has alleged. On the contrary, the Climate Strategy document is corroborated by Heartland’s own material and/or by its allies and employees.
It also uses phrases, language and, in many cases, whole sentences that were taken directly from Heartland’s own material. Only someone who had previous access to all of that material could have prepared the Climate Strategy in its current form.
In all the circumstances – taking into account Peter Gleick’s explanation of the origin of the Heartland documents, and in direct contradiction of Heartland’s stated position – DeSmogBlog has concluded that the Climate Strategy memo is authentic.
