For every scientist that says there is man-made global warming there is another that says its BS.
That is not true. The vast majority of scientist belive that global warming is caused by a big percentage , by man made CO2 emission. They might not agree exactly how this will translate as far as the speed of the repercussion or the amount of repercussion , but agree that there will be important repercution for humankind.
The one who think it is BS are a minority, but are supported by well oiled and very rich organisation:
"For years, a network of fake citizens' groups and bogus scientific bodies has been claiming that science of global warming is inconclusive. They set back action on climate change by a decade. But who funded them? Exxon's involvement is well known, but not the strange role of Big Tobacco. In the first of three extracts from his new book, George Monbiot tells a bizarre and shocking new story

The Guardian
ExxonMobil is the world's most profitable corporation. Its sales now amount to more than $1bn a day. It makes most of this money from oil, and has more to lose than any other company from efforts to tackle climate change. To safeguard its profits, ExxonMobil needs to sow doubt about whether serious action needs to be taken on climate change. But there are difficulties: it must confront a scientific consensus as strong as that which maintains that smoking causes lung cancer or that HIV causes Aids. So what's its strategy?
The website Exxonsecrets.org, using data found in the company's official documents, lists 124 organisations that have taken money from the company or work closely with those that have. These organisations take a consistent line on climate change: that the science is contradictory, the scientists are split, environmentalists are charlatans, liars or lunatics, and if governments took action to prevent global warming, they would be endangering the global economy for no good reason. The findings these organisations dislike are labelled "junk science". The findings they welcome are labelled "sound science".
Among the organisations that have been funded by Exxon are such well-known websites and lobby groups as TechCentralStation, the Cato Institute and the Heritage Foundation. Some of those on the list have names that make them look like grassroots citizens' organisations or academic bodies: the Centre for the Study of Carbon Dioxide and Global Change, for example. One or two of them, such as the Congress of Racial Equality, are citizens' organisations or academic bodies, but the line they take on climate change is very much like that of the other sponsored groups. While all these groups are based in America, their publications are read and cited, and their staff are interviewed and quoted, all over the world.
By funding a large number of organisations, Exxon helps to create the impression that doubt about climate change is widespread. For those who do not understand that scientific findings cannot be trusted if they have not appeared in peer-reviewed journals, the names of these institutes help to suggest that serious researchers are challenging the consensus.
This is not to claim that all the science these groups champion is bogus. On the whole, they use selection, not invention. They will find one contradictory study - such as the discovery of tropospheric cooling, which, in a garbled form, has been used by Peter Hitchens in the Mail on Sunday - and promote it relentlessly. They will continue to do so long after it has been disproved by further work. So, for example, John Christy, the author of the troposphere paper, admitted in August 2005 that his figures were incorrect, yet his initial findings are still being circulated and championed by many of these groups, as a quick internet search will show you."

"Prominent Skeptics Organizations
Global Climate Coalition
Founded in 1989 by 46 corporations and trade associations representing all major elements of US industry, the GCC presents itself as a "voice for business in the global warming debate." The group funded several flawed studies on the economics of the cost of mitigating climate change, which formed the basis of their 1997/1998 multi-million dollar advertising campaign against the Kyoto Protocol. The GCC began to unravel in 1997 when British Petroleum withdrew its membership. Since then many other corporations have followed BP s lead and left the coalition. This exodus reached a fevered pitch in the early months of 2000 when DaimlerChrysler, Texaco and General Motors all announced their exodus from the GCC. Since these desertions, the GCC restructured and remains a powerful and well-funded force focused on obstructing meaningful efforts to mitigate climate change.
Spin: Global Warming is real, but it is too expensive to do anything about. The Kyoto Protocol is fundamentally flawed.
Funding: Corporate members (industries, trade associations etc.)
George Marshall Institute
This conservative think tank shifted its focus from Star Wars to climate change in the late 1980s. In 1989, the Marshall Institute released a report claiming that "cyclical variations in the intensity of the sun would offset any climate change associated with elevated greenhouse gases." Though refuted by the IPCC, the report was very influential in influencing the Bush Sr. Administration s climate change policy. The Marshall Institute has since published numerous reports downplaying the severity of global climate change.
Spin: Blame the Sun. The Kyoto Protocol is fatally flawed.
Affiliated Individuals: Sallie Baliunas, an astrophysicist from Harvard; and Frederick Seitz.
Oregon Institute of Science and Medicine
The Marshall Institute co-sponsored with the OISM a deceptive campaign -- known as the Petition Project -- to undermine and discredit the scientific authority of the IPCC and to oppose the Kyoto Protocol. Early in the spring of 1998, thousands of scientists around the country received a mass mailing urging them to sign a petition calling on the government to reject the Kyoto Protocol. The petition was accompanied by other pieces including an article formatted to mimic the journal of the National Academy of Sciences. Subsequent research revealed that the article had not been peer-reviewed, nor published, nor even accepted for publication in that journal and the Academy released a strong statement disclaiming any connection to this effort and reaffirming the reality of climate change. The Petition resurfaced in 2001.
Spin: There is no scientific basis for claims about global warming. IPCC is a hoax. Kyoto is flawed.
Funding: Petition was funded by private sources.
Affiliated Individuals: Arthur B. Robinson, Sallie L. Baliunas, Frederick Seitz
Science and Environmental Policy Project (SEPP)
Founded in 1990 by widely publicized climate skeptic S. Fred Singer, SEPP s stated purpose is to "document the relationship between scientific data and the development of federal environmental policy." SEPP has mounted a sizeable media campaign -- publishing articles, letters to the editor, and a large number of press releases -- to discredit the issues of global warming, ozone depletion, and acid rain.
Spin: Moreover, climate change won t be bad for us anyway. Action on climate change is not warranted because of shaky science and flawed policy approaches.
Funding: Conservative foundations including Bradley, Smith Richardson, and Forbes. SEPP has also been directly tied to ultra right-wing mogul Reverend Sung Myung Moon s Unification Church, including receipt of a year s free office space from a Moon-funded group and the participation of SEPP s director in church-sponsored conferences and on the board of a Moon-funded magazine.
Affiliated Individuals:S. Fred Singer,Frederick Seitz
Greening Earth Society
The Greening Earth Society (GES) was founded on Earth Day 1998 by the Western Fuels Association to promote the view that increasing levels of atmospheric CO2 are good for humanity. GES and Western Fuels are essentially the same organization. Both used to be located at the same office suite in Arlington, VA. Until December 2000, Fred Palmer chaired both institutions. The GES is now chaired by Bob Norrgard, another long-term Western Fuels associate. The Western Fuels Assocation (WFA) is a cooperative of coal-dependent utilities in the western states that works in part to discredit climate change science and to prevent regulations that might damage coal-related industries.
Spin: CO2 emissions are good for the planet; coal is the best energy source we have.
Affiliated Individuals: Patrick Michaels, Robert Balling, David Wojick, Sallie Baliunas, Sylvan Wittwer, John Daley, Sherwood Idso
Funding: The Greening Earth Society receives its funding from the Western Fuels Association, which in turn receives its funding from its coal and utility company members.
Center for the Study of Carbon Dioxide & Global Change
The Center claims to "disseminate factual reports and sound commentary on new developments in the world-wide scientific quest to determine the climactic and biological consequences of the ongoing rise in the air's CO2 content." The Center is led by two brothers, Craig and Keith Idso. Their father, Sherwood Idso, is affiliated with the Greening Earth Society; the Center also shares a board member (Sylvan Wittwer) with GES. Both Idso brothers have been on the Western Fuels payroll at one time or another.
Spin: Increased levels of CO2 will help plants, and that's good.
Funding: The Center is extremely secretive of its funding sources, stating that it is their policy not to divulge it funders. There is evidence for a strong connection to the Greening Earth Society (ergo Western Fuels Association)."
