The Obama administration know that if the public and the press come to understand how uncertain the causes of climate change really are, then the primary justification for expensive plans to ‘save the climate’ evaporates.
This is precisely why pro-coal spokespeople must focus on the science problems. None of the other issues — job loss, cost, etc. — have the potential to so thoroughly derail the administration’s climate plans as does generating widespread public doubt about the science of climate change.
