I really cannot see how the work of Karl Popper can have any relevance to the climate debate. Popper's Critical Rationalism is based on the belief that if a statement cannot be logically deduced (from what is known), it might nevertheless be possible to logically falsify it.
Climate science is based on the measured facts of changes in such things as weather patterns, rainfall, temperatures windspeeds etc all factual and measurable.
Your absurd suggestion further up that thermometers used in 1850 might we less accurate than modern ones shows such a mind-boggling ignorance of how thermometers work and the fact that the 19th century thermometer collection.sciencemuseumgroup.org.uk/objects/co92811/thermometer-europe-1801-1900-thermometer is identical to the one that was being used until the development of the digital thermometer only a decade or so ago and that side by side they will give the same reading for the same heaated object.
To suggest that thermometers in the past are less accurate than the same device used today, suggests not so much a paradign in science as a complete change either in the structure of the performance of the materials - mercury expanding at a different rate when heated, now compared with nearly 200 years ago, or that the laws of physics have changed.
Kuhn's theories have been substantially challenged by a number of his equals, as much as anything because his theory of paradigm shift has been a normal part of scientific advance and is nowhere as cataclysmic as he suggests. It is also entirely unapplicable to the circumstances of climate change.
Remember what we are discussing here is whether climate change is taking place, not what its cause is. The factual on the ground evidence is there that climate change is taking place.
If you want to take the discussion to its cause. Does it matter?
If your house is on fire, does it matter whether it was caused someone dropping a match or a wiring fault? The main thing to do is to make every effort to put it out, in which case you would use water. What you wouldn't do is pour petrol on it and hope that, as a liquid it would put it out.
Whatever the reason for climate change, it makes sense for us to reduce any activity we engage in that would exacerbate it. It is much more sensible for us to pour water on it and not petrol.
