A small group of experts are saying that the global warming trend is a natural phenomenon, NOT caused by humans.
A group of US scientists have written an article in The International Journal of Climatology, a publication of Britain's Royal Meteorological Society.
"The observed pattern of warming, comparing surface and atmospheric temperature trends, doesn't show the characteristic fingerprint associated with greenhouse warming," wrote a climate expert from the University of Rochester, in New York state.
"The inescapable conclusion is that human contribution is not significant and that observed increases in carbon dioxide and other
greenhouse gases make only a negligible contribution to climate warming," he wrote.
A scientist sfrom the University of Alabama says about satellite data "and independent balloon data agree that the atmospheric warming trends do not exceed those of the surface," while greenhouse models "demand that atmospheric trend values be two to three times greater."
Data from satellite observations "suggest that greenhouse models ignore negative feedback produced by clouds and by water vapor, that diminish the warming effects" of human carbon dioxide emissions.
The journal authors "have good reason, therefore, to believe that current climate models greatly overestimate the effects of greenhouse gases."
A climatologist at the University of Virginia and another co-author, 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 and stalagmites ... and published in hundreds of papers in peer reviewed journals."
Cyclical climate "is most likely caused by variations in the solar wind and associated magnetic fields that affect the flux of cosmic rays incident on cloudiness, and thereby control the amount of sunlight reaching the earth's surface and thus the climate."
At a recent National Press Club meeting in Washington the climatologist said that there is still no definite proof that humans can produce climate change.
"Variations of solar winds and terrestrial magnetic field that impact cloud formations and the amount of sunlight reaching the Earth's surface, and thus determining the temperature -- are much more influential than human-generated greenhouse gas emissions. "
You mean the sky is NOT falling?
I have met two other Californians besides me who do not believe the global warming hype.
One is a route planner for airlines = a climatologis.
The other works for the San Jose Environment department.
Gosh, climatologsits and environmental professions who do NOT believe the sky is falling.
Me, either.
