Many Scientists Say Temperature Drop From Recent Record Highs Is a Blip, While a Few See a Trend; Inexact Climate Models

By Jeffrey Ball, Wall Street Journal

Two years ago, a United Nations scientific panel won the Nobel Peace Prize after concluding that global warming is "unequivocal" and is "very likely" caused by man. Then came a development unforeseen by the U.N.'s Intergovernmental Panel on Climate Change, or IPCC: Data suggested that Earth's temperature was beginning to drop. That has reignited debate over what has become scientific consensus: that climate change is due not to nature, but to humans burning fossil fuels. Scientists who don't believe in man-made global warming cite the cooling as evidence for their case. Those who do believe in man-made warming dismiss the cooling as a blip triggered by fleeting changes in ocean currents; they predict greenhouse gases will produce rising temperatures again soon.
The reality is more complex.
