I have said regularly on this blog that science has been destroyed by several environmental movements. The destruction began with the population explosion that didn't happen and global warming which hasn't happened. Science has justifiably fallen into disrespect.
One of the intellectual pillars of science had been its reliance on falsifiability. Global warming with nearly 20 years of no warming turns out not to be falsifiable.
There is another problem. Science has always used Occam's razor as an important pillar. Occam's razor requires that a simple explanation be preferred to a complex explanation.
Again global warming fails the Occam's razor test.
The test would look solely at global surface temperature which has been 58°F or 20 years and has only risen half a degree Fahrenheit in the previous century. That would be the simple test of validity. Instead, the global warming advocates have pointed to a dozen different irrelevant pieces of evidence to support their theory. Rising oceans, stranded polar bears, shrinking glaciers in the northern hemisphere and any change in the weather from too hot to too cold.
Occam's razor remains a core instrument in the tools of clear and competent thinking. It is no longer relevant to science since science has been so badly sullied.
