The hottest topic in climate research is the observation that global average surface temperature, as well as satellite observations of temperatures in the atmosphere, has shown little or no warming during the 21st century.

Now the political climate is heating up over the same issue. Heated words began circulating last summer, when a team of government scientists from the National Oceanic and Atmospheric Administration (NOAA), led by Thomas Karl, published a paper in Science titled “Possible Artifacts Of Data Biases In The Recent Global Surface Warming Hiatus.”

The press release from NOAA included this statement from Karl, who is head of the National Centers for Environmental Information:   “Adding in the last two years of global surface temperature data and other improvements in the quality of the observed record provide evidence that contradict the notion of a hiatus in recent global warming trends.”

Media headlines quickly touted the Karl conclusion that science now shows the hiatus in warming never existed.
