A U.S. plan to cut greenhouse gas emissions from power plants is not enough to achieve its goals for limiting climate change, and all nations will need to significantly step up actions to curb warming, a group of scientists said in a report on Wednesday.

U.S. carbon emissions are projected to remain above 1990 levels in 2030, even after U.S. President Barack Obama’s administration announced new rules to slash greenhouse gases from power plants by almost a third.

The United States won praise at U.N. talks on climate change on Wednesday for its plan to cut carbon emissions, but a group of scientists said it too little to put the world on track to limit global warming.

Scientists say countries attending United Nations climate talks are going backwards on policy and risking 4C of global warming

The world is getting further off track in limiting global warming with setbacks in Japan and Australia outweighing positive signals from the United States and China, a study showed on Wednesday.

Japan’s watered-down greenhouse-gas pledge has left the Earth facing more warming than four years ago, according to a group of scientists and climate analysts.

New data from the United Nations suggests that under current government arrangements, the world is poised for a 3.7 degree rise in temperature by the end of the century. As James Bourne writes, climate scientist Dr Bill Hare says that to avoid this 'extreme' outcome, member states have to radically rethink their climate change policies.

When Japan dramatically slashed its plans last week for reducing greenhouse gas emissions by 2020, from 25 percent to just 3.8 percent compared to 2005 figures, the international reaction was swift and damning.
