Review process 50 About the Global Warming Policy Foundation 50
by Prof. Ole Humlum, April 2 , 2019 in GWPF
That’s according to Norwegian Professor Ole Humlum whose annual review of the world’s climate is published today by the Global Warming Policy Foundation.
Last week, the WMO issued its own review of the climate, which insinuated that global warming was worsening. However, Professor Humlum points out that the data tells a very different story:
“Reading the WMO report, you would think that global warming was getting worse. But in fact it is carefully worded to give a false impression. The data are far more suggestive of an improvement than a deterioration.”
And the lack of anything to be alarmed about is clear across a range of measures, says Professor Humlum:
“After the warm year of 2016, temperatures last year continued to fall back to levels of the so-called warming “pause” of 2000-2015. There is no sign of any acceleration in global temperature, hurricanes or sea-level rise. These empirical observations show no sign of acceleration whatsoever.”
Professor Humlum’s key findings:
- In 2018, the average global surface temperature continued a gradual descent towards the level characterising the years before the strong 2015–16 El Niño episode.
- Since 2004, when the Argo floats came into operation, the global oceans above 1900m depth have on average warmed somewhat. The maximum warming (between the surface and 120 m depth) mainly affects oceans near the equator, where the incoming solar radiation is at a maximum. In contrast, net cooling has been pronounced for the North Atlantic since 2004.
- Data from tide gauges all over the world suggest an average global sea-level rise of 1– 1.5 mm/year, while the satellite record suggests a rise of about 3.2 mm/year. The large difference between the two data sets still has no broadly accepted explanation.
- The Northern Hemisphere snow cover extent has undergone important local and regional variations from year to year. The overall global tendency since 1972, however, is for overall stable snow extent.
- Tropical storm and hurricane accumulated cyclone energy (ACE) values since 1970 have displayed large variations from year to year, but no overall trend towards either lower or higher activity. The same applies for the number of hurricane landfalls in the continental United States, for which the record begins in 1851.
