New Analysis Does Not Support a Warming “Hiatus”
The “Hiatus” . Annual results for the global average temperature show a break from an earlier high rate of increase, beginning about 1998. Compared with the preceding three decades, recently recorded global average temperatures have shown only a slight increase. The reduction in the rate of warming of the globe may be termed a pause, and is generally referred to as a "hiatus". This difference in warming trends was noted in the Fifth Assessment Report (AR5; Summary for Policymakers and Working Group I: The Physical Science Basis Ch. 2, Observations ) of the Intergovernmental Panel on Climate Change (IPCC). This break has been seized upon by those doubting or denying the reality of global warming as evidence that warming has effectively ceased since about 1998. A new analysis of global temperature data extending from 1880 to the present was published by Thomas Karl and coworkers, from the National Oceanographic and Atmospheric Administration, the Natio...
