Global Warming "Undeniable," U.S. Government Report Says
"Global warming is undeniable," and it's happening fast, a new U.S. government report says.
Such climatic shifts are already ushering in extreme weather, which plagued much of the globe in 2009, according to the report. (See a world map of potential global warming impacts.) For instance, Australia experienced its third hottest year on record.

On one February 2009 day—labeled "Black Saturday"—in Australia, 400 wildfires swept across the state of Victoria, killing 173 people and destroying 3,500 buildings.  [Did CO2 really cause those fires?]
"It's telling us what's going on in the real world, rather than the imaginary world," said Kevin Trenberth, a senior scientist at the Boulder, Colorado-based National Center for Atmospheric Research.

Even so, the report "does not carry the authority of the IPCC [Intergovernmental Panel on Climate Change] by any means," Trenberth noted.
And even with real-world data, "the theory with regard to global warming is still incomplete"—especially since the atmosphere is so complex, Trenberth cautioned.

This "can be seen at a glance," for example, "by looking out of the window at the wondrous, great variety in clouds."
Met Office report: global warming evidence is 'unmistakable' - Telegraph
A new climate change report from the Met Office and its US equivalent has provided the "greatest evidence we have ever had" that the world is warming.
Both the NOAA and Nasa have stated that the first six months of this year were the hottest on record, while the Met Office believes it is the second hottest start to the year after 1998.

Dr Peter Stott, Head of Climate Monitoring and Attribution at the Met Office, said “variability” in different regions, such as the cold winter in Britain, does not mean the rest of the world is not warming.

And he said 'greenhouse gases are the glaringly obvious explanation' [Why, specifically, is this "glaringly obvious"?] for 0.56C (1F) warming over the last 50 years.
Dr Stott said the sceptics can no longer question the land surface temperature as other records also show global warming.

He pointed out that each indicator takes independent evidence from at least 3 different institutions in order to ensure the information is correct. Despite variations from year to year, each decade has been warmer than the last since the 1980s. [ie, since right after the last global cooling scare ended]

I believe the "hottest on record" is taken from a comparison of the 1961-2009 average, which leaves out the hot decade of the 30's.

Trenbreth is the one who commented in the Climategate e-mails that they were nowhere close to balancing the "energy budget", which means they have no idea about what's going on and he also was "complaining" about the cold in Colorado and mused about what has "happened to global warming."
