President Obama says US serious about Climate Change

President Barack Obama stated he is serious about the US acting positively to combat climate change in a speech at the United Nations on Monday.  "The US is determined to act"  Obama said.    At the United Nations climate change conference he also called for developing nations to take strong measures on greenhouse gas emissions to boost hopes for a global deal on global warming.

In a speech aimed at US domestic opinion as well as the rest of the world, Obama called on rapidly-growing developing nations such as China and India that will produce nearly all growth in carbon emissions to act as well.

"Some of these nations have already made great strides with the development and deployment of clean energy," Obama said.  "Still, they will need to commit to strong measures at home and agree to stand behind those commitments just as the developed nations must stand behind their own."
