The Democrats are losing the 'climate change' debate because they refuse to partipate
...This is a mistake they have made from the beginning of their push for control freak government to deal with their perceived views of the climate. Their push for regulations that harm workers and the economy is causing them to lose political support for their agenda. If they can't justify it by something other than calling those who dissent from their views "deniers" they are going to continue to lose and Trump's deregulation efforts that create job will add to those who do not support them.
Their effort should be dismissed as a rousing failure, and as an affront to the scientific method that they purport to adopt in their studies. The first error is one of approach. The worst way to get a full exchange of views on the complex matter of global warming is to pack the IWG entirely with members from the Obama administration, all surely preselected in part because they share the president’s exaggerated concerns with the problem of global warming. The only way to get a full and accurate picture of the situation is to listen to dissenters on global warming as well as advocates, which was never done. After all, who should listen to a “denier”?
This dismissive attitude is fatal to independent inquiry. No matter how many times the president claims the science is rock-solid, the wealth of recent evidence gives rise to a very different picture that undercuts the inordinate pessimism about climate change that was in vogue about 10 years ago. The group convened in the Obama administration never examined, let alone refuted, the accumulation of evidence on the other side. Indeed, virtually all of its reports are remarkable for the refusal to address any of the data at all. Instead, the common theme is to refer to models developed by others as the solid foundation for the group’s own work, without questioning a word of what those models say.
