NASA Administrator, Michael Griffin, is backing away from comments he made last week in a National Public Radio interview. At the time Griffin stated that, " ...a trend of global warming exists, I am not sure that it is fair to say that it is a problem we must wrestle with.”

Today the White House appointed Griffin is apologizing to NASA staff saying that,

All I can really do is apologize to all you guys ... I feel badly that I caused this amount of controversy over something like this."

A new United Nations study says hundreds of millions of livelihoods will be affected by melting snow and ice due to climate change , and time is running out for political leaders to reach agreement on curbing emissions.

A BBC investigation has found that after more than two years the program has boosted electricity bills and given windfall profits to power companies without achieving its touted objective of slashing carbon emissions.

The Bush administration is drastically scaling back efforts to measure global warming from space, just as the president tries to convince the world the U.S. is ready to take the lead in reducing greenhouse gases.

Scientists said they will face major gaps in data that can be collected only from satellites about ice caps and sheets, surface levels of seas and lakes, sizes of glaciers, surface radiation, water vapor, snow cover and atmospheric carbon dioxide.

China vowed to "blaze a new path to industrialisation" today as it unveiled its first national plan on climate change.

But in a blow to efforts to tackle global warming, the world's second biggest producer of greenhouse gases refused to accept binding targets for emissions, saying wealthy developed nations must take the bulk of the responsibility for the problem.
