German flagship news magazine Spiegel Online today has an article authored by Axel Bojanowski which takes a close look at the recent John Cook survey. German alarmists like the Potsdam Institute for Climate Impact Research hailed it as proof that climate science was settled and done.
But Spiegel draws a different a totally conclusion.
First Bojanowski describes how a large number of Americans have serious doubts when it comes to man-made climate change, and so surveys get conducted with the aim of trying to sway public opinion. The latest was carried out by John Cook of the University of Queensland in Australia, and the results were published in the journal of Environmental Research Letters: 97% of thousands of papers surveyed agree that climate change is man-made, it asserted.
But Bojanowski trashes the findings:
There’s an obvious discrepancy between the public perception and reality. The authors speak about ‘consensus on man-made climate change’ – and thus this threatens to further increase confusion within the public. The survey confirms only a banality: Climate scientists overwhelmingly agree that man is responsible for at least a part of the climate warming. The important question of how big is man’s part in climate change remains hotly disputed.
In the draft of the next UN report that will summarize climate science knowledge in September, it is stated: ‘It is extremely likely that human activity is responsible for more than half of the warming since the 1950s.’ The estimations from scientists on the exact extent vary vastly – here the consensus ends.”
Bojanowski then gives Spiegel readers the results produced by Cook: “About two thirds took no position on the subject – they remained on the sidelines. 97% of the rest supported man-made impact.
Also in an additional step, 35% of the authors who took no position were left out of the survey results altogether.
A new German survey produces similar results: no consensus!
Bojanowski then reports on another still unpublished German survey conducted by the University of Mainz in Germany. Senja Post told SPIEGEL ONLINE that “123 of 292 climate scientists asked participated in the study“. The result (warmists may want to sit down before reading):
Only 5% of those responding believed natural factors played the main role in the warming. However, Post then asked about the extent of the man-made warming. The result looked very different. Only 59% of the scientists said the ‘climate development of the last 50 years was mostly influenced by man’s activity. One quarter of those surveyed said that human and natural factors played an equal role’.”
Only 10% of German scientists say computer models are sufficiently accurate
Bojanowski then writes that skepticism is even far more widespread when it comes to the reliability of computer models. “Only 10% said climate models are ‘sufficiently accurate’ and only 15% said that ‘climatic processes are understood enough’ to allow climate to be calculated.”
Bojanowski sums up: “There’s plenty of fodder there to continue the ideologically influenced debate about climate – no matter what is said about consensus.”
