Is Global Warming a Bipolar Disorder? | Patrick J. Michaels | Cato Institute: Commentary: 'We now have a full one-third of a century of satellite-measured lower atmospheric temperatures, and what an interesting story the machines are revealing. I think it’s fair to say that they provide increasing evidence in favor of the “lukewarm” view of climate change, or the hypothesis of modest warming. In climate change, “it’s not the heat, it’s the sensitivity”, or the amount of warming that a change in carbon dioxide causes, that is important.'

'For a number of reasons, computer models with added atmospheric carbon dioxide preferentially warm the mid-and high-latitude land areas of the northern hemisphere that are ice-free, which also enhances summer melting of the relatively shallow ice in the Arctic Ocean. That, in turn, results in an increased absorption of solar radiation by the darker ocean surface, which also contributes to warming.'
