Because of the importance of clarity in a debate with muddied waters, Peter Gleick admits that he muddied the waters in the interest of clarifying muddied waters.

This is rich:

... I received an anonymous document in the mail describing what appeared to be details of the Heartland Institute's climate program strategy. It contained information about their funders and the Institute's apparent efforts to muddy public understanding about climate science and policy. I do not know the source of that original document....

Given the potential impact however, I attempted to confirm the accuracy of the information in this document. In an effort to do so, and in a serious lapse of my own and professional judgment and ethics, I solicited and received additional materials directly from the Heartland Institute under someone else's name....

And then he mixed it all up together for our delectation. Mmmm. Taste it: the Real-and-Fake cocktail. Much better than straight real, which is quite bland. No kick! And "climate change" is so very, very important.
