"I think that the latest IPCC report has truly sunk to level of hilarious incoherence," Dr. Richard Lindzen told Climate Depot, a global warming skeptic news site. "They are proclaiming increased confidence in their models as the discrepancies between their models and observations increase."

This is undeniable, as climate scientists note the discrepancies between reality and their predictive models in the IPCC report itself.

"Germany called for the reference to the slowdown to be deleted, saying a time span of 10-15 years was misleading in the context of climate change, which is measured over decades and centuries," the AP report said. "The U.S. also urged the authors to include the 'leading hypothesis' that the reduction in warming is linked to more heat being transferred to the deep ocean."

Global warming skeptics have exploited such data to show that the science behind manmade global warming is faulty and politically driven.

"[I]n attributing warming to man, they fail to point out that the warming has been small, and totally consistent with there being nothing to be alarmed about," Lindzen said. "It is quite amazing to see the contortions the IPCC has to go through in order to keep the international climate agenda going."

However, believers in catastrophic global warming have said the UN report should serve as a wake-up call to those who would deny the issue's urgency.

"Those who deny the science or choose excuses over action are playing with fire," said Secretary of State John Kerry. "Once again, the science grows clearer, the case grows more compelling and the costs of inaction grow beyond anything that anyone with conscience or common sense should be willing to even contemplate."
