US NOAA issued a report in July 2010 that stresses that the "global warming is undeniable." This report investigates 10 climate-related indexes such as sea surface temperature, temperature over land and sea ice cover from the real world observations.
This should be regarded complimentary to the approach by IPCC, the world's leading body for the environmental issues, where it develops global climate models and predicts the future climates based on the models. The importance of the NOAA report is that it pronounces that the global warming is the fact derived from the real data.
As opposed to the dull responses to the environmental issues under the Busch administration, US already declared in December 2009 that greenhouse gases threaten the public health and welfare of current and future generations. The NOAA report clearly follows this view.
Around the same time, US EPA rejected claims issued by the fossil fuel industry and other opponents of action on climate change. It's a strong message that EPA is determined to regulate greenhouse gases.
It's a sheer surprise to me that there are still a bunch of people who stand against the global warming.
