The US, the largest greenhouse gas emitter in the world, may soon be picking up the challenge of address climate change.
Senator John Kerry, en route to international climate change talks in Poland said, "It's a very exciting time. It's a moment we have been waiting for, many of us, for some period of time; we intend to pick up the baton and really run with it."
President-elect Obama has been "very, very clear that after eight years of obstruction and delay and denial, the US is going to rejoin the world community in tackling this global challenge," added Senator Kerry who will be an observer at the December 1st to 12th Conference.
Kerry said the US message will be "that America is back, we are back in a position of participation, of respecting views and having real discussions and trying to find the best framework for all of us."
The United States is currently the only industrialized nation not to ratify the emission-capping Kyoto Protocol.
