Today's Guardian reports on a landmark resolution in Washington, D.C., endorsing an atmospheric limit for carbon dioxide a carbon dioxide cap and trade system.

The G8+5 Climate Change dialogue, part of the British group Global Legislators Organisation for a Balanced Environment, brought together leading industries and politicians from rapidly developing countries (like China and India) and the advanced G-8 member states to discuss the issue of Global Climate Change.

But what does this resolution actually do?

Not much—it’s non-binding. But it did prove, if you didn’t already know, politicians of all stripes are publicly stating the need to address global climate change.

From the Guardian's report:

Although the talks are informal and do not represent official government policy, analysts said they provided a good indication of current political thinking on climate change…

The US senator Joe Lieberman told the forum yesterday that he believed the American legislators would introduce greenhouse gas cutting laws in the near future "after many years of denial and inaction" on global warming.

"I want to make a prediction, which is that the Congress of the United States will enact a nationwide law mandating substantial reductions in greenhouse gases before the end of this Congress or early in the next," he said. This session of Congress ends late in 2008.

Senator John McCain said the push to reduce the greenhouse gas emissions that spur global climate change was a national security issue, and that voluntary efforts to limit these emissions from vehicles, power plants and other human sources "will not change the status quo".

How do others shape up this recent development?
