Thanks to Linda for her comment about the issue of global warming. Madame L apologizes to Linda and to all her Dear Readers for posting such a long video the first time she wrote about this.
Here's a shorter video with most of the essential information from Michael Mann's TED Talk.
Madame L will be writing more about this soon. She is currently reading Michael Mann's book, "The Hockey Stick and the Climate Wars: Dispatches from the Front Lines"; and will write a review of it within the next week or two.
