Climate scientists have no concrete way of proving or disproving global warming theories, according to Rupert Darwall, a London-based expert in energy and climate policy.
The truth is, climate scientists don't know," Darwell, author "
The Age of Global Warming: A History," told "The Steve Malzberg Show" on Newsmax TV.
"They've got climate models that make projections and these climate models have run too hot.
"The crucial question for them to answer is: by what year, if the climate hasn't bounced back to its trend predicted by the climate models, when will they say, well actually we got this wrong. That for them is the question they don't answer."

Darwall — author of "The Age of Global Warming: A History,"
published by Quartet Books — said nobody really knows by how much increased levels of carbon dioxide cause the atmosphere to warm.
"When you look at the climate models, they have had a terrible predictive record," he said.
"They completely missed the fifteen to seventeen year pause in global temperatures that we are now seeing."
Darwall said there is powerful evidence to suggest that the huge push for de-carbonization is "literally insane."
"And that is the big emerging economies absolutely refuse to sign up to a global treaty that hinders their ability to grow their economies and pump out carbon dioxide," he said.
He said former Vice President Al Gore, a major booster of global warming theories, was drastically wrong.
"At an early climate conference, which was in 2007 … he predicted that the Arctic Sea ice would disappear in the summer by around about now, 2014, 2015," Darwall said.
"He also in his movie, 'An Inconvenient Truth' … oh, the Greenland ice sheet is going to melt and now cause a new Ice Age in Europe.
"What he didn't tell anyone is that the melting, if it happens of the Greenland ice sheet, isn't in decades or centuries – it's millennia. The earliest it would melt is in 1,000 years' time. What didn't he say that?"
