The web world went crazy for Live Earth this weekend, the 24-hour, 7-continent concert series. The concert marked the beginning of a multi-year campaign led by the Alliance for Climate Protection, The Climate Group and other international organisations in a bid to help drive action to solve global warming. Former U.S. Vice President Al Gore is the Chair of the Alliance and Partner of Live Earth.
If want want to take a look at the London concert, the site contains a host of images and videos from the event if you missed it, as well as a video of the UK concert itself.
If you want a snap shot of what the blog world's reaction has been, take a look at Technorati, which showed, at the time of writing, Live Earth as one of the most searched for terms.
