Early 2007 saw Record-Breaking Extreme Weather: U.N.

You would have to be a moron or a fool at this point not to realize that the weather is being affected by what we humans have done to the atmosphere:

The world experienced a series of record-breaking weather events in early 2007, from flooding in Asia to heatwaves in Europe and snowfall in South Africa, the United Nations weather agency said on Tuesday.

The World Meteorological Organization (WMO) said global land surface temperatures in January and April were likely the warmest since records began in 1880, at more than 1 degree Celsius higher than average for those months.

[...]While most scientists believe extreme weather events will be more frequent as heat-trapping carbon dioxide emissions cause global temperatures to rise, Baddour said it was impossible to say with certainty what the second half of 2007 will bring.

Speaking of "fool":

A U.S. summit in September on climate change, one of at least four international meetings set for this year, is already raising doubts about any action being taken before President George W. Bush leaves office.

[...]"The constant excuse that the United States has given for not participating in a climate regime, by blaming India and China ... is not just unfortunate but I think is very far from the truth," Sunita Narain, director of India's Center for Science and Environment, told reporters at the U.N. session.
