Riddler_This: Climate change is real and man-made, explains University of Waterloo professor Qin-Bin Lu, author of a new study published this week in the peer-reviewed journal, Physics Reports.
Professor Lu also explains that the climate change crisis is over. Thanks to an international environmental treaty, the planet is no longer in peril. We have, in fact, begun a long cooling period that will bring Earth's temperatures back to normal.
The man-made cause of global warming is not CO2 and the international treaty that saved the planet is not the Kyoto Protocol. Rather, says Dr. Lu, the true cause of global warming has been CFCs, or chlorofluorocarbons, a class of chemicals that was once widely used in aerosol cans and refrigeration. As CFC use soared in the decades following World War II, he explains, the globe started warming dramatically. The world stopped warming dramatically when government regulations began to phase out CFCs, an event that culminated in the western world in 2000. Almost immediately afterward, in 2002, the world began to cool as CFCs started to diminish in our atmosphere
But what made Prof. Lu come to this conclusion?
Professor Lu, a path-breaking scientist in the field of ozone protection, made his CO2 discovery by accident — he was looking for culprits in the formation of the ozone hole over Antarctica. A chief suspect was CO2: Climate models produced by climatologists showed that CO2 would have devastating effects on the ozone layer, significantly enlarging the ozone hole over Antarctica and dramatically enlarging it over the Arctic. But when Dr. Lu compared the imagined output of the climate models with the actual measurements taken real-time by satellites and weather balloons, the models turned out to be soaring failures.
"I didn't see any CO2 effect on temperature or ozone depletion over the South Pole from 1956 to 2008," explained Dr. Lu, surprised at how totally different the real-world measurements were from those that the climate model predicted. The real-world measurements showed CO2 to be largely irrelevant -"the global warming on Earth's surface between 1950 and 2000 is pretty much due to CFCs," he concluded. "The models say that CO2 is a major greenhouse gas but the facts show otherwise."
In contrast, CFCs have long been known to be a greenhouse gas that, on a molecule per molecule basis, is 10,000 times more potent than CO2. Professor Lu's satellite and balloon measurements showed that factor of 10,000 to have been a gross underestimate!
Although this is intriguing, consider that correlation does not imply causality and there was scant evidence beyond Prof. Lu's authority cited in the article. However, here's more:
In his paper, Qing-Bin Lu, a professor of physics and astronomy, shows how CFCs – compounds once widely used as refrigerants – and cosmic rays – energy particles originating in outer space – are mostly to blame for climate change, rather than carbon dioxide (CO2) emissions. His paper, derived from observations of satellite, ground-based and balloon measurements as well as an innovative use of an established mechanism, was published online in the prestigious journal Physics Reports.
"My findings do not agree with the climate models that conventionally thought that greenhouse gases, mainly CO2, are the major culprits for the global warming seen in the late 20th century," Lu said. "Instead, the observed data show that CFCs conspiring with cosmic rays most likely caused both the Antarctic ozone hole and global warming. These findings are totally unexpected and striking, as I was focused on studying the mechanism for the formation of the ozone hole, rather than global warming."
His conclusions are based on observations that from 1950 up to now, the climate in the Arctic and Antarctic atmospheres has been completely controlled by CFCs and cosmic rays, with no CO2 impact.
"Most remarkably, the total amount of CFCs, ozone-depleting molecules that are well-known greenhouse gases, has decreased around 2000," Lu said. "Correspondingly, the global surface temperature has also dropped. In striking contrast, the CO2 level has kept rising since 1850 and now is at its largest growth rate."
In his research, Lu discovers that while there was global warming from 1950 to 2000, there has been global cooling since 2002. The cooling trend will continue for the next 50 years, according to his new research observations.
Finally, if you want to look at the article source here it is via Science Direct:
The cosmic-ray driven electron-induced reaction of halogenated molecules adsorbed on ice surfaces has been proposed as a new mechanism for the formation of the polar ozone hole. Here, experimental findings of dissociative electron transfer reactions of halogenated molecules on ice surfaces in electron-stimulated desorption, electron trapping and femtosecond time-resolved laser spectroscopic measurements are reviewed. It is followed by a review of the evidence from recent satellite observations of this new mechanism for the Antarctic ozone hole, and all other possible physical mechanisms are discussed. Moreover, new observations of the 11 year cyclic variations of both polar ozone loss and stratospheric cooling and the seasonal variations of CFCs and CH4 in the polar stratosphere are presented, and quantitative predictions of the Antarctic ozone hole in the future are given. Finally, new observation of the effects of CFCs and cosmic-ray driven ozone depletion on global climate change is also presented and discussed.
adamleath27: "as the decades of the 80's came to an end , there was much talk about global warming and the "greenhouse effect" . scientist argued that the climate of earth is indeed warming and, morever, the the cause of the warming is primarily the burning of hydrocarbons, such as oil and coal, by humans.the increasing concentrations of carbon dioxide and other "greenhouse gases" in the atmosphere, they argue, is causing the warming trend we have experienced. " and......
adamleath27: one thought is from the 80's to 2002 ? all the atmospher that would burn off has burned off ?
adamleath27: "other scientist disagree. they argue that our recent experience of abnormally warm weather may well just be a fluctuation in earth's overall climate. so there may not even be a genuine warming trend at all. moreover, it is claimed, there are other mechanisms involving ocean curents and atmospheric winds that could produce the warm years we have experienced.

adamleath27: " meanwhile,agencies of the united nations and other international organizations have publicly urged the major industrial nations, which are responsible for most of the greenhouse gases, to take stringent measures to reduce the production of these gases. but many goverments, including the united states, have argued that such measures would be costly. they cite disagreements within the scientific community over the existence of global warming and its supposed causes as evidence that more study is needed.while the debate is going on, not much is being done to reduce hydrocarbon emissions.is the lack of action by major industrialnations understandable in the light of the existing scientific controversy ?
adamleath27: then theres the wagner model, " the object of study is the climate of earth. according to the greenhouse model ??? earth's atmosphere acts like the windows in a greenhouse, trapping light and heat under the atmospher. carbon dioxide increases the effiency with which the atmospher traps heat. guessing earth's temperature should be be increasing. how ever , this is not developed in sufficient details to permit precise guessing of how much the temperature should increase by specified information or wether the increases would be uniform around the world. this information included the drought of 88' in the u.s. also the decade of the 80's....the info and guessing seemed to agree. some climatologist use a alternate called the lorenz model. and there is something important to note. bla bla blaaa and.....

adamleath27: like there was this dude, from china, that rode a hot air balloon into space and parashooted back to earth & video'd it. "whaaaa"
adamleath27: so ancient times..the earth is a magnet. and scientist study magnetism, geomagnetism and paleomagnetism iguess determining how the earths magnetic feild has changed ? has the earths rotation slowed down ? do earth quakes cause shift in earths positioning ? is earths rotation around the sun still the same ? or are we slowly globally warming......or has earth settled in a new rotating axil position ?
adamleath27: so lets see, forcast calls for mother earth to rotate back and fourth but gravity will hold her in place centering in the middle of the invisable layers of protection ? furthermore; "the sunshine can't shine all the time" feb.2nd,2012
