Rocket Scientist: No Evidence CO2 Causes Global Warming
The campaign to force people to accept that "the debate is over" and that man-made CO2 emissions are driving climate change is in deep trouble, with another top global warming advocate - rocket scientist and carbon accounting expert Dr. Richard Evans - completely reversing his position.
Evans was a consultant to the Australian Greenhouse Office from 1999 to 2005 and he wrote the carbon accounting model (FullCAM) that measures Australia's compliance with the Kyoto Protocol.
In an article for The Australian newspaper, Evans highlights why he was so keen to jump on board the man-made explanation without there being any clear conclusion as to what was driving temperature increases in the period from the end of the 70's to 1998.
"The evidence was not conclusive, but why wait until we were certain when it appeared we needed to act quickly?" writes Evans. "Soon government and the scientific community were working together and lots of science research jobs were created. We scientists had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet."
"But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming," he concludes.
Evans points out that the "greenhouse signature" that would indicate CO2 emissions are driving temperature increases - "a hot spot about 10km up in the atmosphere over the tropics" - which would be evident if climate change was man-made, is simply non-existent.
"If there is no hot spot then an increased greenhouse effect is not the cause of global warming. So we know for sure that carbon emissions are not a significant cause of the global warming," he writes.
Evans highlights data collected from satellites positioned around the globe that indicates temperatures have dropped about 0.6C in the past year - back to 1980 levels. Such figures are complimented by anecdotal evidence of a cooling pattern - China recently experienced its coldest winter in 100 years while northeast America was hit by record snow levels and Britain suffered its coldest April in decades as late-blooming daffodils were pounded with hail and snow on an almost daily basis.
Evans also cites historical climate change and the fact that CO2 does not cause, but in fact lags behind temperature increase by as much as 800 years.
"The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect," he writes.
"The last point was known and past dispute by 2003, yet Al Gore made his movie in 2005 and presented the ice cores as the sole reason for believing that carbon emissions cause global warming. In any other political context our cynical and experienced press corps would surely have called this dishonest and widely questioned the politician's assertion," writes Evans.
Evans warns that the insistence on behalf of the man-made advocate establishment that "the debate is over," despite the fact that a CO2 link to climate change "was merely asserted, not proved," and the glee with which governments have adopted measures to fight global warming under this false assumption, will cause economies to be wrecked and as temperatures cool further, authorities will have to face charges of "criminal negligence" for deliberately lying to the public about climate change.
Evans' public reversal of his position arrives on the back of two peer reviewed scientific papers, one of which documents how C02 emissions in fact cool the planet's temperature and another that shows how the IPCC overstated CO2's effect on temperature by as much as 2000 per cent.
As we reported last week, the world is cooling, sea levels are falling, ice is spreading, there are fewer extreme weather events, and it was hotter 1000 years ago, yet the myth of global warming is providing governments the excuse to micromanage every aspect of our lives, with Al Gore now openly calling for a carbon tax on the energy we use.
Andrew Bolt of the Australian Sun-Herald has put together a series of graphs based on numbers from a plethora of scientific bodies to prove that the most alarmist claims about climate change are not only unproven, but in fact the complete opposite of what man-made global warming advocates proclaim is now being observed.
