I have a couple of PhD theses that I have to read this week, so I probably won’t get to read the new Synthesis Report from the Copenhagen Conference for a few days. But it looks like it will be worth the wait. According to RealClimate, it’s a thorough look at how much the science has changed since the IPCC AR4 report in 2007, along with some serious discussion on what needs to be done to hold the world below the threshold of 2°C of warming.
