I wonder if this is "legit" .. there have been attempts to discredit those outside the media by creating false stories about reports which may or may not exist :

Climate warming is naturally caused and shows no human influence:
Carbon dioxide (CO2) is not a pollutant.
Climate scientists at the University of Rochester, the University of Alabama, and the University of Virginia report that observed patterns of temperature changes (‘fingerprints’) over the last thirty years are not in accord with what greenhouse models predict and can better be explained by natural factors, such as solar variability. Therefore, climate change is ‘unstoppable’ and cannot be affected or modified by controlling the emission of greenhouse gases, such as CO2, as is proposed in current legislation.
These results are in conflict with the conclusions of the United Nations Intergovernmental Panel on Climate Change (IPCC) and also with some recent research publications based on essentially the same data. However, they are supported by the results of the US-sponsored Climate Change Science Program (CCSP).
The report is published in the December 2007 issue of the International Journal of Climatology of the Royal Meteorological Society [DOI: 10.1002/joc.1651]. The authors are Prof. David H. Douglass (Univ. of Rochester), Prof. John R. Christy (Univ. of Alabama), Benjamin D. Pearson (graduate student), and Prof. S. Fred Singer (Univ. of Virginia).
The fundamental question is whether the observed warming is natural or anthropogenic (human-caused). Lead author David Douglass said: “The observed pattern of warming, comparing surface and atmospheric temperature trends, does not show the characteristic fingerprint associated with greenhouse warming. The inescapable conclusion is that the human contribution is not significant and that observed increases in carbon dioxide and other greenhouse gases make only a negligible contribution to climate warming.”
Co-author John Christy said: “Satellite data and independent balloon data agree that atmospheric warming trends do not exceed those of the surface. Greenhouse models, on the other hand, demand that atmospheric trend values be 2-3 times greater. We have good reason, therefore, to believe that current climate models greatly overestimate the effects of greenhouse gases. Satellite observations suggest that GH models ignore negative feedbacks, produced by clouds and by water vapor, that diminish the warming effects of carbon dioxide.”
Co-author S. Fred Singer said: “The current warming trend is simply part of a natural cycle of climate warming and cooling that has been seen in ice cores, deep-sea sediments, stalagmites, etc., and published in hundreds of papers in peer-reviewed journals. The mechanism for producing such cyclical climate changes is still under discussion; but they are most likely caused by variations in the solar wind and associated magnetic fields that affect the flux of cosmic rays incident on the earth’s atmosphere. In turn, such cosmic rays are believed to influence cloudiness and thereby control the amount of sunlight reaching the earth’s surface—and thus the climate.” Our research demonstrates that the ongoing rise of atmospheric CO2 has only a minor influence on climate change. We must conclude, therefore, that attempts to control CO2 emissions are ineffective and pointless. – but very costly.

I have been saying this for years...
One more time:
We are an ovaloid planet whose orbit is also ovaloid, other planets affect our climate as we pass them as do other 'space' type items (comets, asteroids etc).
We have seen via science that we have had 'hot spells' & also 'Freezes' (read Ice ages)...
All we can not accertain through the wonders of science is the "when's the next one".
We in this age have 'complained' about it warming up... it maybe 2 more or 2,000 more generations before the people of earth start to whine about why it's getting so bloody cold... & of course there will be people pointing fingers at others as the cause for the cooling off (freezing).
It's nature, it's a cycle, we just don't know how to time this...
Just imagine how the 'early man' felt as his homelands kept getting hotter & hotter (or colder & colder), at some point they started to blame the 'gods'...
Well as we know, most sciences & gods don't mix, so people look to other reasons... cars, sheep farts etc...
We should just ride it out, we may fry to a frazzle but it won't be due to anything man has done. |
