Despite the heated rhetoric from the Obama administration and environmental groups about the urgency of global warming, climate scientists have begun to come to terms with the lack of evidence of catastrophic global warming over the last decade.

“While, some climate scientists continue to resist the obvious that the climate system is more complex than they assumed, others are starting to accept that the multi-decadal climate projections provide very incomplete simulations has to how the real climate system works,” Roger Pielke, Jr., environmental studies professor at the Center for Science and Technology Policy Research at the University of Colorado at Boulder, told The Daily Caller News Foundation.
