New Analysis Does Not Support a Warming 'Hiatus' - Energy Collective

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 National Centers for Environmental Information, and LMI (McLean, VA), on June 4, 2015. Climate scientists recognized problems in the ways temperature data have been collected. Karl and coworkers sought to reevaluate historical data to account for these problems (see Details section at the end of this post). The scientists conclude “based on our new analysis, the IPCC’s … statement of two years ago – that the global surface temperature ‘has shown a much smaller increasing linear trend over the past 15 years than over the past 30 to 60 years’ – is no longer valid.” Rather, the rate of warming of the world's atmosphere during 1998 to 2014, averaged over its entire surface, has continued unabated compared to the warming experienced in earlier decades (see Details).

Warming Skeptics. Almost immediately upon the publication of this report organizations known to be skeptical about global warming, or to deny that it is occurring and/or that humanity is causing it, issued statements questioning the validity of the report. However it is essentially impossible for these groups to draw such conclusions without actually taking the time to review the data and methods used in the reanalysis. After all, the authors devoted many months or more to analyze the information available. The data sets themselves are available to the public, and the report sets out in detail how the analysis was done. Detractors can only question the validity of the conclusions reached by Karl and coworkers after critically reviewing this information and objectively pointing to any perceived faults in the analysis. Anything short of such assessment is mere speculation.

Ocean Heat Content. The reanalysis conducted by Karl and coworkers importantly shows that air temperatures averaged over the surface of the entire globe have continued to increase without any pause from about 1950 to the present. In addition, the oceans absorb about 90% of the excess heat accumulated by the complete earth system. Measurements collected over the past decades show that the heat content contained in the oceans has continued increasing without cease during this period.
