"The Koch Brothers and Their Amazing Climate Change Denial Machine" is a short animation detailing the effort of billionaire oil barons Charles and David Koch to undermine belief in climate change and prevent legislation that threatens their profits. By pouring money into bogus scientific studies and funding think tanks and front groups, the public is led to believe a genuine scientific debate is raging. In truth, as one climate denier candidly admits, those doubting the science are just a small, if brilliantly coordinated, minority.
