Sierra club- $25 million from gas alone 350.org funded by big oil (Rockefellers)
The Sierra Club has received funding from the following groups: the Pew Charitable Trusts, the Joyce Foundation, the Charles Stewart Mott Foundation, the Blue Moon Fund, the David and Lucile Packard Foundation, the Energy Foundation, the Turner Foundation and the Tides Foundation and Tides Center.
In November 2011, the Los Angeles Times reported that green-energy investor David Gelbaum has donated over $100 million to the Sierra Club in recent decades.  Additionally, in July 2011, New York City Mayor Michael Bloomberg’s charity announced plans for a $50 million dollar donation to the Sierra Club’s “campaign to shut down coal-fired power plants.”
In 2011, the Sierra Club had total revenues of $97,757,678.
350.org has the look and feel of an amateur, grassroots operation, but in reality, it is a multi-million dollar campaign run by staff earning six-digit salaries.
By my analysis of information from the U.S. Foundation Center and the tax filings of American charitable foundations, McKibben’s campaigns have received more than 100 grants since 2005 for a total of US$10-million from 50 charitable foundations. Six of those grants were for roughly US$1-million each."
George Soros, the oil billionaire among other investments, funds a number of climate propaganda organisations, Environmental Media Services, MoveOn.org, The Open Society Institute, I thought jut the main well known groups pushing the climate agenda were his, but the list here goes on for pages.
Soros funded groups
"MoveOn spends millions to support liberal politicians while simultaneously attacking conservatives. MoveOn spent $21.6 million to support Democrats in the 2004 election. Hollywood elites such as Oliver Stone and Rob Reiner have made ads for MoveOn."
"GetUp was inspired by, and modelled on similar US groups, such as MoveOn.org and Win Back Respect. Madden and Heniman were co-founders of Win Back Respect. According to public records published on CampaignDonations.com, when they were drawing expenses from the group in 2004, the major donor that year, with a contribution of $150,000 was George Soros.
Madden and Heimans are also involved with another Soros-financed left-wing activist group, MoveOn.org. Public records reveal that between January 2003 and December 2004, Soros contributed $2,500,999 to MoveOn.org." Source
DeSmogBlog are a typical cowboy outfit DeSmogBlog details
DeSmogBlog is a smear site founded by a scientifically unqualified public relations man, James Hoggan and funded by a convicted money launderer, John Lefebvre. The irony here is their favorite tactic is to attempt to smear those they disagree with as funded by "dirty money"
Al Gore's Climate Reality Group: "The Climate Reality Project is a non-profit group. It has come under scrutiny for electioneering and charges have been filed with the Federal Election Commission. Describing its work as a “mass persuasion exercise,” the Climate Reality Project generated $88 million in revenues in 2008.

"Earthworks is an American non-profit environmental organization. Based in Washington, D.C., Earthworks seeks to prevent or limit mining operations, natural gas production, hydraulic fracturing and oil production. Earthworks is a vocal opponent of mining in Bristol Bay, Alaska, an area commonly known as the Pebble Mine." Now why would they want to do that exactly?
"Extreme left-wing foundations such as the Tides Foundation, the Gordon & Betty Moore Foundation and the David & Lucile Packard Foundation provide significant funding to Earthworks."
One of the largest organisations, and the ones who fund Michael Mann's so far unsuccessful lawsuits for anyone who questions his work, is the Suzuki Foundation. This includes a graph of their funding. I'd guess they alone wouldwipe out the total for every single group on the other side. Their average funding has risen from $3 million a year to closer to $9 million. And guess what, these donations aren't for charity, they all expect something back and more. That's the nature and basis of political donations, they are seen as investments as well as helpful tax losses.

Of course, ultimately, the piddling amounts paid to the 'denial organisations' like the Heartland Institute, and GWPF, compared to the governments and UN vanish into obscurity. These 'deniers', who incidentally regularly publish data which can all be independently verified, rather than the models and predictions from the other side, neither of which pass a single test of scientific method, and simply allow the small scale media to publish the genuine material many of the larger levels won't touch. Comparing the amounts spent on a handful of contrary organisations compared to the vast array of large scale environmental groups headed by Greenpeace and the WWF, who are actually supposed to be apolitical charities (although Greenpeace has had its charitable status stripped in some countries now as a direct result), means the combined amounts from heavyweight PR and the far greater amounts spent by governments, in the billions, are an irrelevant diversion. Eventually I may be able to balance the two general sums so everyone can both see the difference and the official sources, but till then the figures here still speak for themselves and point to the obvious known conclusion.
