A recent article in Nature Geoscience that shows that measurable climate change - this time the expansion of the tropics - is outpacing predictions. The actual article is abstracted here: http://www.nature.com/ngeo/journal/vaop/ncurrent/abs/ngeo.2007.38.html
Amazing how the strong belief system of "scientists"/fervent AGW co-religionists (government employees of course; this time NOAA) has actually been measurably changing the climate!
A press release by Nature Geoscience reported the following:
The tropical belt, defined by its typical rain and wind patterns, has started to expand during the last few decades as a result of climate change, according to a progress article published online this week in Nature Geoscience. This ongoing expansion, emerging from a number of independent studies, will affect climate worldwide as the dry subtropical zones are pushed polewards and could come to encompass the Mediterranean region, the southwest USA, Mexico, southern Australia, South Africa and parts of South America.
Dian Seidel and colleagues review recent studies on the width of the tropical belt from independent signs such as changes in atmospheric temperatures, winds and ozone observations, which all distinguish the tropical from the subtropical regions. According to their findings, the tropics have expanded by about 2.5 degrees latitude over the past 25 years or so - an expansion that had not been expected to occur before the end of the twenty-first century from climate model projections.
A further report provides the following background:
Climate models predict that global warming could be causing the tropics to expand. So far, they have suggested a creep of 2°of latitude north and south, but only over the next century.
To find out what has happened so far, a team led by climate scientist Dian Seidel of the National Oceanic and Atmospheric Administration in Silver Spring, Maryland, examined the stratosphere for signs of change in the tropics. She and colleagues surveyed five sets of data collected by satellites and weather balloons from 1979 to 2000. The data showed that tropical climate patterns, such as increased ozone concentrations and temperatures, in the stratosphere had expanded by up to 4.5°of latitude--depending on the observations--in the Northern Hemisphere during that short period. ...
Atmospheric scientist John Wallace of the University of Washington, Seattle, says the survey "makes a compelling case that the tropical belt has widened substantially over the past 30 years," and if it continues at the same rate, "it will have major societal implications."
The lead hysteric/scientist results reportedly said:
"Dr Seidel said the surprisingly rapid expansion of the tropics could lead to "profound changes in the global climate system". Of greatest concern were shifts in rain and wind patterns that would affect natural ecosystems, agriculture and water resources in the world's subtropical dry belts, including southern Australia. ...
"Dr Seidel and her colleagues analysed results from five different types of measurements of the tropics, including ozone levels and temperature.
"These independent studies all found that the tropical zone had expanded between 1979 and 2005 within estimates ranging from two to eight degrees of latitude. This was already greater than the 2-degree expansion by 2010 that climate change models have predicted under the most extreme warming scenario."

How convenient - government "scientists" happen to find consistent evidence, across a number of parameters, that climate change is occuring, and faster than predicted by climate models.
How can we possibly trust this information from the government-funded AGW scientific cartel, whose only incentive is to keep the "climate change" goose well-fed, so they can keep collecting golden eggs from taxpayers?
Perhaps a more accurate headline would be "Scientists Again Prove Climate Models Wrong!" That would be just as correct, and make me feel better, too.
