Climatologist Dr. Judith Curry warns of decades of possible global cooling: Suggests the ‘current cool phase will continue until the 2030s’

Climatologist Dr. Judith Curry, who was until recently the Chair of School of Earth & Atmospheric Sciences at Georgia Institute of Technology, detailed her conversion from a scientist who accepted the global warming “consensus” on man-made global warming to one who now openly challenges it. Curry spoke at the National Press Club in Washington DC on September 16 at an event sponsored by the George C. Marshall Institute.

Curry warned of possible global cooling. “We also see a cooling period starting around the turn of the (21st) century.” She also suggested that the “current cool phase will continue until the 2030s.” [Also see: Scientists and Studies predict ‘imminent global COOLING’ ahead – Drop in global temps ‘almost a slam dunk’]

“Even on the timescale of decade or two, we could end up be very surprised on how the climate plays out and it might not be getting warmer like the UN IPCC says,” Curry noted.

“We don’t know what’s going to happen. All other things being equal – yes — more carbon dioxide means warmer, but all other things are never equal,” she emphasized.

“We just don’t know. I think we are fooling ourselves to think that CO2 control knob really influences climate on these decadal or even century time scales,” she added.

“I view the [climate change] problem as a ‘big wicked mess,” Curry told the crowd at luncheon assembled. “The main problem is we are putting the policy cart before the scientific horse,” Curry said.

Curry believes the United Nations has distorted the research of global warming and shifted too much on carbon dioxide as the “control knob” of the climate system. “Climate scientists have focused primarily on greenhouse gases,” Curry noted, linking that focus on the IPCC’s focus and the funding streams available to scientists who focus on CO2.

“Other factors relatively neglected,” Curry declared.

“The early articulation of a preferred policy option by the UN framework marginalized research on broader issues surrounding climate change and resulted in an overconfident assessment of the importance of greenhouse gases in future climate change and stifled development of a broad range of policy options.”

UN Treaty Futility

Curry also dismissed the UN global climate treaty process. “Relying on global international treaty to solve the problem — which I …
