"My fellow citizens"

Apart from the stiring inspiration that might be expected an an inauguration speech, Barack Obama made more than a couple of references to the task of dealing with climate change.

Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age.

..and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.

But our time of standing pat, of protecting narrow interests and putting off unpleasant decisions – that time has surely passed.

With old friends and former foes, we will work tirelessly to lessen the nuclear threat, and roll back the spectre of a warming planet.

Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America... We will harness the sun and the winds and the soil to fuel our cars and run our factories... All this we can do. All this we will do.
