The co-founder of the Weather Channel and climate expert John Coleman recently wrote an open letter directly attacking the Intergovernmental Panel on Climate Change, arguing that attempts to prove man-made climate change “have failed” and that political agendas rather than science are now driving the “scientific” conversation.
Here's an excerpt of from the open letter (via Express News):
The ocean is not rising significantly.
The polar ice is increasing, not melting away. Polar Bears are increasing in number.
Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing).
I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid. […]
There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future.
Efforts to prove the theory that carbon dioxide is a significant greenhouse gas and pollutant causing significant warming or weather effects have failed.
There has been no warming over 18 years.
Princeton’s William Happer, another climate expert and outspoken climate change skeptic, added to Coleman’s arguments:
No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonisation of this natural and essential atmospheric gas by advocates of government control and energy production.
The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.
The IPCC maintains that their research points to coming weather crises due to global warming, but in 2010 a study by the InterAcademy Council found "little evidence" to support IPCC's claims. The report also found that the panel was deliberately emphasizing potential negative impacts of climate change, which supports Coleman’s and Happer’s charges of the panel’s politicization of climate science.
Here’s an interview with Coleman from March where he debunks global warming science by presenting a larger context for global temperature trends (begins shortly after the 2:20 mark):
