Somehow in its haste to scare us, the AAAS seems to have missed (or ignored) the two hottest topics in climate change these days—1) that climate models have done remarkablypoorly in replicating the evolution of global temperature during the past several decades , and 2) that high end climate change scenarios from the models are largely unsupported by observations.
Thus, “what the science is showing” completely undermines the AAAS contentions regarding alarming climate change.
