USA and Obama to fight climate change....

President Barack Obama has promised that the US will lead the world on climate change and make clean energy a priority.

In the course of a ten-minute announcement at the White House, Mr Obama became the first American President to put cleaner energy at the heart of his domestic agenda and to envision environmentalism as a creator of jobs, economic stability and a boost to the nations security.

"No single issue is as fundamental to our future as energy. America will not be held hostage to dwindling resources, hostile regimes and a warming planet," Obama stated in his annoucement.

As one of the world largest emitters of green house gas, the US has signified a massive swing in the global politics of climate change. Other developed countries, including Australia, can now no longer use the excuse that without the US onboard, climate change mitigation is meaningless and will damage their economies.
