London, 6 September: The General-Secretary of the World Meteorological Organization (WMO) says that the alarmist narrative on climate change has gone off the rails and criticised the news media for provoking unjustified anxiety.
Speaking to Finland’s financial newspaper Talouselämä (“The Journal”) on 6 September 2019, Petteri Taalas called for cooler heads to prevail, saying that he does not accept arguments of climate alarmists that the end of the world is at hand.
Dr Taalas also spoke of the dangers of green extremism:
“While climate sceptisism has become less of an issue, now we are being challenged from the other side. Climate experts have been attacked by these people and they claim that we should be much more radical. They are doomsters and extremists; they make threats.”
And he called for the media both to challenge experts and allow a broader range of opinions to be heard.

Most of us are familiar with the World Meteorological Organization (WMO)-recommended 30-year period for “normals”, which are also used as base years against which anomalies are calculated. Most, but not all, climate-related data are referenced to 30-year periods. Presently the “climatological standard normals” period is 1981-2010. These “climatological standard normals” are updated every ten years after we pass another year ending in a zero. That is, the next period for “climatological standard normals” will be 1991-2020, so the shift to new “climatological standard normals” will take place in a few years.
But were you aware that the WMO also has another recommended 30-year period for “normals”, against which anomalies are calculated? It’s used for the “reference standard normals” or “reference normals”. The WMO-recommended period for “reference normals” is 1961-1990. And as many of you know, of the primary suppliers of global mean surface temperature data, the base years of 1961-1990 are only used by the UKMO.
