Yesterday, NASA came out with a statement that 2007 was the 2nd warmest year. However, NOAA already has said 2007 was the 5th warmest. If 2 government agencies can't even agree on what data is correct, how can we believe either of them? Who do we trust?
Another Gulf Low will spread rain back our way by late Friday. As the low pulls to our east on Saturday, it'll pull bitterly cold air down to the Gulf Coast. Highs on Saturday staying in the 40s with windchills in the 20s & 30s. Sunday morning lows will be 24-28 on the Northshore and 30-35 Southshore. Fortunately the cold quickly pulls away for next week.

Way to go Bob, you forgot to mention the 65 degree temps. in Chicago two weeks ago or the tornado's that almost destroyed my parents home in WI in JANUARY!! A first. But thankfully we have a cool weekend so global warming dosen't exist.
Bob do we have to protect pipes this weekend?
Hmm.
Global Warming is Good!!!!!

American Geophysical Union Position Statement:
Human Impacts on Climate
Adopted by American Geophysical Union Council December 2003
Revised and Reaffirmed December 2007
The Earth's climate is now clearly out of balance and is warming. Many components of the climate system—including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons—are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6°C over the period 1956–2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.
During recent millennia of relatively stable climate, civilization became established and populations have grown rapidly. In the next 50 years, even the lower limit of impending climate change—an additional global mean warming of 1°C above the last decade—is far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2°C above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, and—if sustained over centuries—melting much of the Greenland ice sheet with ensuing rise in sea level of several meters. If this 2°C warming is to be avoided, then our net annual emissions of CO2 must be reduced by more than 50 percent within this century. With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections.
With climate change, as with ozone depletion, the human footprint on Earth is apparent. The cause of disruptive climate change, unlike ozone depletion, is tied to energy use and runs through modern society. Solutions will necessarily involve all aspects of society. Mitigation strategies and adaptation responses will call for collaborations across science, technology, industry, and government. Members of the AGU, as part of the scientific community, collectively have special responsibilities: to pursue research needed to understand it; to educate the public on the causes, risks, and hazards; and to communicate clearly and objectively with those who can implement policies to shape future climate.
