First, there are no proofs in the natural sciences. Second: do you understand the concept of falsification?
Correct, and yes I do.
If I put forth a hypothesis in the natural sciences, I can only gather evidence that does or does not support my hypothesis. Without the possibility of proof, I cannot prove it is true. However, I CAN logically prove it false.
By "hypothesis", you mean 'theory', since you are speaking of an explanatory argument here... A theory is an explanatory argument.
For example, suppose I hypothesize that all swans are white. I can count white swans all day and the more white swans I find, the more likely is my hypothesis to be correct.
No, the more white swans you find does NOT in any way make your "hypothesis" (you actually mean 'theory') any more correct, or any more likely to be correct. All that means is that your theory hasn't been falsified as of yet. You would be reasonable to accept the "all swans are white" theory as correct until you or someone else falsifies it.
But if I come across a single black swan, my hypothesis is done for because I said "ALL swans are white".
You mean 'theory', not 'hypothesis', but yes you are correct here. The sighting of the black swan completely falsifies your theory. It is no longer a theory of science.
Of course, I might just coincidentally count a very large number of white swans and never run into a black one and this might be enough evidence that I and my co-researchers become convinced that the hypothesis is correct.
Nope, not how science works. It's not about "enough evidence" to "become convinced"... That is how RELIGION works, NOT science... Your coincidentally counting a very large number of white swans (never running into a black one) only means that your theory of science is withstanding null hypothesis testing. It is continuing to remain a theory of science.
In pseudoscience, however, you will frequently see hypotheses that are simply not falsifiable. Anything that makes use of the supernatural: claims that a certain god exists or that any god exists or claims that some event was caused by a supernatural entity is not testable because the supernatural by definition, cannot be tested by scientific methods. Hypotheses such as the existence of the Loch Ness monster, the Abominable Snow Man, Bigfoot, alien visitors cannot be falsified and so are not valid hypotheses.
You mean 'theory', but yes, god(s), Loch Ness, Bigfoot, etc. are all religions. They are not falsifiable, thus they are not within the realm of science.
There has long been an argument that anthropogenic global warming (AGW) was not falsifiable. My list was simply a dozen ways in which it COULD be falsified. They are the foundations of the theory. Take any of them away and the theory collapses.
It is not even a defined term... So far, it has only been circularly defined... That type of definition is meaningless...
And, of course, every one of them HAS been thoroughly tested.
Many of those things actually show the complete denial of science and mathematics by the AGW crowd...
CO2 absorbs infrared radiation in several discrete bands. That is all that is required to determine that it is a greenhouse gas.
Absorbing IR is not trapping heat, air, nor thermal energy.
However, further testing has definitively shown that it produces increased warming from exposure to infrared radiation, another demonstration of its satisfaction of the definition of a greenhouse gas. Look up the absorption spectrum of CO2.
CO2 cannot warm the Earth. Heat cannot flow backwards, Crick... See the 2nd Law of Thermodynamics...
Several organizations have been collecting CO2 level data since the 1950s. They all show levels steadily increasing. Look up the Keeling Curve.
Sure, data is being collected. I don't deny that. I am simply telling you that the data being collected is NOT 'global CO2 content' data... It is measured at specific locations, and those locations are subject to location and time biases, which are not properly accounted for. Mauna Loa has been known to cook their data, so they aren't even putting out raw data. Statistical Mathematics axioms are not being followed, rendering the data (on a global level) useless.
Isotopic analysis of CO2 in Earth's atmosphere has repeatedly shown that 131 ppm of the current 411 ppm originates with the combustion of fossil fuels.
Made up numbers... It is not possible to measure global CO2 content. We don't have enough stations (nor are they uniformly spaced and simultaneously read) to even BEGIN such a statistical analysis.
Additionally, calculations based on accurate estimates of the amount of fossil fuel burned since the beginning of the Industrial Revolution closely match the results of isotopic analysis.
We have never used fossils for fuel. They do not burn very well. Also, more made up numbers... See above.
Virtually every molecule of CO2 above the pre-industrial level of 280 ppm came from the combustion of fossil fuels and is thus of human origin.
Again, more made up numbers. See above.
You're new to these arguments, aren't you.
No, I'm not. I've heard them before. This is nothing new for me.
You misunderstand. I am listing methods by which the theory of AGW could be falsified. The theory is falsifiable. It is valid in that regard. That is has not BEEN falsified by anyone so far is another strong piece of evidence that it is correct
Global Warming (Climate Change) isn't even adequately defined, Crick... Circular definitions do not work. They are meaningless.
I've shown elsewhere precisely how AGW denies both science and mathematics (in addition to denying logic).
