The big news overnight was of course Obama's state of the Union address, in which he announced that he was going to get tough on climate change:
U.S. President Barack Obama on Tuesday gave Congress an ultimatum on climate change: craft a plan to slash greenhouse gas emissions and adapt to the dangers of a warming world, or the White House will go it alone.
"If Congress won't act soon to protect future generations, I will," Obama said in his State of the Union address. "I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.
Whether he means this or not will only become true in the fullness of time. But isn't it extraordinary, or perhaps not, that none of this new evidence on low climate sensitivity seems to have made the slightest difference to the political process?
