The key requirement for the method of science is scepticism.
The scientific method is to make falsifiable hypotheses and then to check the hypothesis by gathering the evidence to check the falsifiability.
The IPCC and the Global Warming Orthodoxy have been making alarmist predictions for the last 20 years and their hypothesis comes in three parts:
- That global warming is occurring and will continue for at least the next 100 years
- That human activities are the primary cause of the global warming being observed, and
- That man-made emission of carbon-dioxide is the most significant human activity driving climate change.
In the last 20+ years, comparing actual observations show that each one of these 3 parts of this global warming hypothesis is – at best – oversimplified and – at worst – just plain wrong. “Wrong” in the sense that the causality proposed does not exist and that the mechanisms proposed for the causality are incorrect or non-existent. The IPCC predictions are being proved wrong and it is time to ditch the hypothesis.
The 27th January article in the Wall Street Journal “No Need to Panic about Global Warming” by a number of scientists displaying true scientific scepticism was immediately criticised by members of the Orthodoxy. The original authors now reply to these criticisms in the WSJ:
