The melt in Greenland and the high temperatures in Alaska may be more signs—like we needed more—of the reality of climate change. Even scarier is the fact that the climate models used before didn’t predict this sort of thing. The climate is very complex, and it’s hard to model it accurately. This is well-known and is why it’s so hard to make long-term predictions. But before the deniers crow that climatologists don’t know what they’re doing, note this well: The predictions made using these models almost always seem to underestimate the effects of climate change. That’s true in this case, too. So it’s not that the models are wrong and therefore climate change doesn’t exist. It’s that the models aren’t perfect, and it’s looking like things are worse than we thought.
