The authors, Andy May and Marcel Crok, argue that the sceptical position on dangerous man-made climate change is supported by a comprehensive literature review. In other words, those who are disparagingly labelled by the establishment as “climate change deniers” have credible evidence on their side.
The main argument made in May and Crok’s paper is that the evidence presented by the United Nations Intergovernmental Panel on Climate Change (“IPCC”) to support the claim that human-caused climate change is dangerous is not convincing.
Firstly, the IPCC claims that human greenhouse gas emissions are the “main driver” of warming since 1979, but this is disputed. Natural climate oscillations like the Atlantic Multidecadal Oscillation (“AMO”) can explain a significant portion of the 20th century warming.
The AMO is a cyclic phenomenon of sea surface temperature (“SST”) anomalies in the North Atlantic Ocean. It has a significant impact on global weather patterns. The theoretical measure of the variability of the SST of the North Atlantic Ocean is called the AMO index.
The AMO index oscillates between positive and negative phases. During the positive phase, the North Atlantic Ocean experiences warm SSTs, while during the negative phase, SSTs are cooler. The AMO index is associated with shifts in hurricane activity, rainfall patterns and intensity, as well as changes in fish populations....<<<Read More>>>...
