From Michael Jackson's "Earth Song" debuted in the U.S. at the Grammy Awards this past Sunday to the news that researchers have determined the lightning observed during the eruption of Mt. Redoubt in 2009, to be an entirely new variety of lightning, a lot happened this week in green. One man has made it his mission to hunt one of the largest freshwater crocodiles -- at 25 feet long -- known for having eaten over 200 people; new research from NASA shows that the length of the summer ice-melt season lasts on average 20 days longer than it did in the 1980s, and and an internal investigation by Penn State University has determined that one of the key players in 'Climategate' has been entirely cleared of the most serious allegations of misconduct made against him. Find out what else happened in the world of green this week in our photo roundup of most popular, most important, and most oddball stories.
