Is a two degree rise small enough?

The G8 leaders' recent announcement setting a limit of two degrees to global warming above today's global average (and cuts in emissions by 2050) is the subject of a blog post in the NYT's Dot Earth blog. Andrew Revkin explores the pros and cons of setting targets like two degrees; 'It’s not hard to find climate scientists and policy experts who strongly feel the world needs to move rapidly to curb emissions, but who say there are no such clean lines. Some go further, saying that setting such thresholds can be counterproductive.' Quotes from various sources illustrate some of the issues with the announcement.
