Levenfeld Pearlstein, the law firm that has stepped up to pass on complaints about the publication of leaked Heartland Institute documents, appears to be one of the greenest in Chicago. For example, James Brusslan, head of the Environmental Services Group at Levenfeld Pearlstein, says companies should act now to prevent climate change because:

The IPCC has determined with virtual certainty that humans are the cause of significant global warming due to increased emissions of greenhouse gases (GHG), including carbon dioxide and methane. Many scientists believe if we do not take action quickly, the impact could be catastrophic.

It would be interesting to know how Brussland gets along with Michael Padden, son of the Heartland Institute’s founder David Padden and author of the most recent letter asking the DeSmogBlog to take down the document that describes, accurately and succinctly, Heartland’s Climate Strategy for 2012.
