Another New Study Supports Early 21st Century Warming Hiatus Was Real

A new study by Williams et al appearing in the Journal of Atmospheric and Solar Terrestrial Physics shows that the global warming hiatus of the early 20th century was in fact real.

A number of scientists from the alarmist camp like to insist that there had never been such a hiatus. The latest paper contradicts that claim.

The new study states that many published analyses show that lightning activity is responsive to temperature on time scales ranging from the diurnal to the decadal and that the hiatus in global warming earlier this century can be seen in several global datasets.

Scientists found that the statistically flat behavior of the global lightning record from the NASA Lightning Imaging Sensor over the same decadal period is consistent with this hiatus in global warming.

What follows is the paper’s abstract:

Multiple records of global temperature contain periods of decadal length with flat or declining temperature trend, often termed a ‘hiatus’. Towards assessing the physical reality of two such periods (1940–1972 and 1998–2014), lightning data are examined. Lightning activity is of particular interest because on many different time scales it has been shown to be non-linearly dependent on temperature.During the earlier hiatus, declining trends in regional thunder days have been documented. During the more recent hiatus, lightning observations from the Lightning Imaging Sensor in space show no trend in flash rate. Surface-based, radiosonde-based and satellite-based estimates of global temperature have all been examined to support the veracity of the hiatus in global warming over the time interval of the satellite-based lightning record. Future measurements are needed to capture the total global lightning activity on a continuous basis.”

So much for settled science.
