> It's unfortunate that this will be used as ammunition for climate skeptics. That will always happen, though it only shows that these people don't understand science: That "we don't know every detail about climate change and there's scientific controversy and new discoveries about many details" does not equal "we have a controversy about the basic facts of climate change". Interesting enough the collapse of the west antarctic ice shield was a major point of criticism where people said the IPCC got things wrong, because they were underplaying risks. It seems the debate isn't over. We'll see how it plays out.
