You haven't demonstrated that there is man made global warming or climate change. You're using evidence of one thing to make conclusions about another
Interesting. So it is becoming more clear what Mach's game is.
Let me take a stab at telling you what it is (because Mach won't)
You will have to provide PERFECT evidence that a society over the course of 150 or so years producing as much greenhouse gas as humans have done on
this earth over the past 150 years, to change the climate in
exactly the same way as the current climate has changed.
That will mean you will have to have the following things:
1. ANOTHER earth in
exactly the same orbital configuration as the current earth going back 150 years
2. ANOTHER Sun in
exactly the same states of solar flux and sunspot cycles going back 150 years
3. ANOTHER group of humans on this other earth producing
exactly the same amount of greenhouse gases at the exact same rate as we have for 150 years.
At that time you will have a "controlled" experiment to compare with this one.
But Mach would probably also be a "stickler" for STATISTICAL ROBUSTNESS so this will have to be repeated at least 3-5 additional times.
I suggest we run them in parallel (otherwise that is 450-750 years worth of invested time), but this WILL cost a lot of money since we will have to create about 3-5 ADDITIONAL EARTHS and 3-5 ADDITIONAL SUNS.
Otherwise we simply cannot know ANYTHING about ANYTHING!
Mach is right. Science is all a lie and we can know NOTHING. This is why sciences like GEOLOGY is such a failure it has only been able to oversee the most expansive advancement in fuels and material goods in human history. But it, too, requires we understand how earth works.
And we clearly can't do that with just one earth.
So if we are all REAL scientists (like Mach is) we should get right on it and start doin' our jobs!
