New Global warming puzzle: Is it the sun?

Space.com: Global Warming on Pluto Puzzles Scientists
In what is largely a reversal of an August announcement, astronomers today said Pluto is undergoing global warming in its thin atmosphere even as it moves farther from the Sun on its long, odd-shaped orbit.

- Space.com: New Storm on Jupiter Hints at Climate Change
The latest images could provide evidence that Jupiter is in the midst of a global change that can modify temperatures by as much as 10 degrees Fahrenheit on different parts of the globe. http://www.space.com/scienceastronom...04_red_jr.html

- Current Science & Technology Center: Global Warming on Mars?
A study of the ice caps on Mars may show that the red planet is experiencing a warming trend. If both Mars and Earth are experiencing global warming, then perhaps there is a larger phenomenon going on in the Solar System that is causing their global climates to change.

NASA says its Cassini spacecraft has found a hurricane-like storm at Saturn's South Pole, nearly 5,000 miles across -- or two-thirds Earth's diameter. http://www.upi.com/NewsTrack/view.ph...9-022035-4126r

- Science Agogo: Global Warming Detected on Triton
There may not be much industrial pollution on Neptune's largest moon, but things are hotting up nonetheless. "At least since 1989, Triton has been undergoing a period of global warming," confirms astronomer James Elliot, professor of Earth, Atmospheric and Planetary Sciences at Massachusetts Institute of Technology. "Percentage-wise, it's a very large increase." Whoops - You Broke Something!

- Associated Press: Study says sun getting hotter
Solar radiation reaching the Earth is 0.036 percent warmer than it was in 1986, when the current solar cycle was beginning, a researcher reports in a study to be published Friday in the journal Science. The finding is based on an analysis of satellites that measure the temperature of sunlight.

- London Telegraph: The truth about global warming - it's the Sun that's to blame
Global warming has finally been explained: the Earth is getting hotter because the Sun is burning more brightly than at any time during the past 1,000 years, according to new research.
http://www.telegraph.co.uk/news/main...ixnewstop.html

The simple fact is that throughout the ages the earth has swung wildly between a warm, wet, stable climate, to a cold, dry and windy one - long before the first fossil fuel was burned. The changes we are now witnessing are a walk in the park compared to the battering that our planet has taken in the past.

This is not a defense of the oil cartels or the Neo-Con wreckers, who would have every motivation to ignore global warming whether it is man-made or not.

Nor is it a blanket denial of the fact that the earth is getting very gradually hotter, but how do we reconcile global warming taking place at the farthest reaches of the solar system with the contention that it is caused by human activity? Have our exhaust fumes left earth's atmosphere and slipped through a black hole to Triton?

The assertion that global warming is man made is so oppressively enforced upon popular opinion, especially in Europe, that expressing a scintilla of doubt is akin to holocaust denial in some cases. Such is the insipid brainwashing that has taken place via television, newspapers and exalted talking heads - global warming skeptics are forced to wear the metaphoric yellow star and only discuss their doubts in hushed tones and conciliatory frameworks, or be cat-called, harangued and jeered by an army of do-gooders who righteously believe they are rescuing mother earth by recycling a wine bottle or putting their paper in a separate trash can.

Fearmongering about an imminent climate doomsday also hogs news coverage and important environmental issues like GM food, mad scientist chimera cloning and the usurpation and abuse of corporations like Monsanto flies under the radar.

Global warming is cited as an excuse to meter out further control and surveillance over our daily lives, RFID chips on our trash cans, GPS satellite tacking and taxation by the mile, as well as a global tax at the gas pump.

The extremist wing of the environmentalist movement, characterized by people like Dr. Erik Pianka, advocate the mass culling of humanity via plagues and state sanctioned bio-terrorism, in order to "save" the earth from the disease of humanity. Nazi-like genocial population control measures and the environmental establishment have always held a close alliance.

The orthodox organized religion of global warming and its disastrous consequences for our freedom of speech, freedom of mobility and our right to remain outside of the system, needs to be questioned on the foundational basis that the phenomenon is solar-system wide and it is mainly caused by the natural evolution of the sun and not human activity. http://www.prisonplanet.com/articles...suvjupiter.htm

Yes. Global surface temperatures have increased about 0.6°C (plus or minus 0.2°C) since the late-19th century, and about 0.4°F (0.2 to 0.3°C) over the past 25 years (the period with the most credible data). The warming has not been globally uniform. Some areas (including parts of the southeastern U.S.) have, in fact, cooled over the last century. The recent warmth has been greatest over North America and Eurasia between 40 and 70°N. Warming, assisted by the record El Niño of 1997-1998, has continued right up to the present, with 2001 being the second warmest year on record after 1998.
Linear trends can vary greatly depending on the period over which they are computed. Temperature trends in the lower troposphere (between about 2,500 and 26,000 ft.) from 1979 to the present, the period for which Satellite Microwave Sounding Unit data exist, are small and may be unrepresentative of longer term trends and trends closer to the surface. Furthermore, there are small unresolved differences between radiosonde and satellite observations of tropospheric temperatures, though both data sources show slight warming trends. If one calculates trends beginning with the commencement of radiosonde data in the 1950s, there is a slight greater warming in the record due to increases in the 1970s. There are statistical and physical reasons (e.g., short record lengths, the transient differential effects of volcanic activity and El Niño, and boundary layer effects) for expecting differences between recent trends in surface and lower tropospheric temperatures, but the exact causes for the differences are still under investigation (see National Research Council report "Reconciling Observations of Global Temperature Change").
An enhanced greenhouse effect is expected to cause cooling in higher parts of the atmosphere because the increased "blanketing" effect in the lower atmosphere holds in more heat, allowing less to reach the upper atmosphere. Cooling of the lower stratosphere (about 49,000-79,500ft.) since 1979 is shown by both satellite Microwave Sounding Unit and radiosonde data, but is larger in the radiosonde data.
Relatively cool surface and tropospheric temperatures, and a relatively warmer lower stratosphere, were observed in 1992 and 1993, following the 1991 eruption of Mt. Pinatubo. The warming reappeared in 1994. A dramatic global warming, at least partly associated with the record El Niño, took place in 1998. This warming episode is reflected from the surface to the top of the troposphere.
There has been a general, but not global, tendency toward reduced diurnal temperature range (DTR), (the difference between high and low daily temperatures) over about 50% of the global land mass since the middle of the 20th century. Cloud cover has increased in many of the areas with reduced diurnal temperature range. The overall positive trend for maximum daily temperature over the period of study (1950-93) is 0.1°C/decade, whereas the trend for daily minimum temperatures is 0.2°C/decade. This results in a negative trend in the DTR of -0.1°C/decade.
Indirect indicators of warming such as borehole temperatures, snow cover, and glacier recession data, are in substantial agreement with the more direct indicators of recent warmth. Evidence such as changes in glacier length is useful since it not only provides qualitative support for existing meteorological data, but glaciers often exist in places too remote to support meteorological stations, the records of glacial advance and retreat often extend back further than weather station records, and glaciers are usually at much higher alititudes that weather stations allowing us more insight into temperature changes higher in the atmosphere.
Large-scale measurements of sea-ice have only been possible since the satellite era, but through looking at a number of different satellite estimates, it has been determined that Arctic sea ice has decreased between 1973 and 1996 at a rate of -2.8 +/- 0.3%/decade. Although this seems to correspond to a general increase in temperature over the same period, there are lots of quasi-cyclic atmospheric dynamics (for example the Arctic Oscillation) which may also influence the extent and thickness of sea-ice in the Arctic. Sea-ice in the Antarctic has shown very little trend over the same period, or even a slight increase since 1979. Though extending the Antarctic sea-ice record back in time is more difficult due to the lack of direct observations in this part of the world. More on the way!
