"Dark Money" And The Funding Of Climate Change Denial

It used to be easy to determine who was providing the funding for climate change denial organizations.  For example, prior to 2008, it was easy to trace the traditional funding sources such as Koch Industries and Exxon- Mobile.  Today 140 foundations funnel the money to climate denial organizations.  Between 2003 and 2010 $558 million was funneled through foundations which are not required to disclose their donors.  Around 25% of the funding went through DonorsTrust which is the largest source of climate denial funding.  Since 2008 there is no trace of funding coming from Exxon or Koch Industries or other traditional funding sources.  The public is unable to determine who has paid for the reports that shape the way governments might respond to the threat of global warming.
