Here’s an eye-opening article in The Independent:
A secretive funding organisation in the United States that guarantees anonymity for its billionaire donors has emerged as a major operator in the climate “counter movement” to undermine the science of global warming.
The Donors Trust… is funnelling millions of dollars into the effort to cast doubt on climate change without revealing the identities of its wealthy backers or that they have links to the fossil fuel industry.
Donors is being indirectly supported by the American billionaire Charles Koch who, with his brother David, jointly owns a majority stake in Koch Industries, a large oil, gas and chemicals conglomerate….
Anonymous private funding of global warming sceptics is becoming increasingly common. The Kochs, for instance, have overtaken the corporate funding of climate denialism by oil companies such as ExxonMobil. [It is] estimated that over the past decade about $500m has been given to organisations devoted to undermining the science of climate change, with much of the money donated anonymously through third parties.
