The IPCC summarises climate change research. The first of their three reports, on the physical science of climate change, is out now. It covers the research since the IPCC’s last report, in 2007. After reviewing about 10,000 papers, the message is very simple:
The more fossil carbon we burn, the hotter it will get. It doesn’t really matter how fast we burn it, but if we dig it up and burn it, then we commit the planet to warming.
And that’s that. You can read the rest of the report if you like, but the single key message is right there.
