Climate science violates the basic precepts of science May 9, 2019 by Sanjeev Sabhlok There are two key pillars of science. First, it doesn’t matter how many “scientists” believe something. All of them could be proven wrong by a single new scientific theory or experiment. Science is always tentatively proven, and it is incumbent on everyone who calls himself a scientist to ask questions even about things that are “settled”. The great physicist Richard Feynman rightly said, “Science is the belief in the ignorance of experts”. Scientists must continually question everything and everybody. Second, science must necessarily make accurate predictions. The global positioning system (GPS) in our mobile phones works only because Einstein’s theories of relativity are accurate to the last possible decimal. Science must not just predict the future: it must predict backwards. Our scientific understanding of cosmic microwave background radiation allows us to literally see the universe as it existed a few thousand years after the Big Bang. With climate change, things are dramatically unclear and unsettled. Even converting the basic logic of the greenhouse effect into actual estimates for planet Earth is not settled. The IPCC’s Third Assessment Report notes that "If the amount of carbon dioxide were doubled instantaneously … the temperature of the surface-troposphere system would have to increase by 1.2 degrees, in the absence of other changes”. However, some scientists calculate that its impact would be much lower. Even if we accept this figure of 1.2 degrees, the key question is about these “other changes”, or the feedbacks. IPCCs tells us that positive feedback loops (e.g. from water vapour) from doubling of CO2 will overwhelm negative feedback loops (e.g. from clouds) to lead to a much higher overall temperature in a hundred years. But the IPCC’s approved models have too much variance and the actual, measured temperatures over the past forty years have been much lower than the predicted average of the IPCCapproved climate models. In fact, the list of failed predictions by climate “scientists” over the past 100 years could form a large book in itself. Climate science is more like “diet science”, in which every second doctor has his own ideas about a good diet. It is a very immature science at best, and most of its current conclusions will be totally rejected with time. 1
