What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?
If you have it....lets see it. If you don't....then lets hear your best excuse for not providing it.

Please tell us how CO2 controls the climate... I'll wait...
Good ahead refute NASA.

LOL..
Which set of facts? You post up shit without a clue and runaway like a little *****... Please be specific as to what you believe is true.
How about you just pick one.
No problem... Lets take on the one about shrinking ice sheets.
The link says:
The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 286 billion tons of ice per year between 1993 and 2016, while Antarctica lost about 127 billion tons of ice per year during the same time period. The rate of Antarctica ice mass loss has tripled in the last decade.7
Does that in any way provide evidence that we are causing the reduction in ice, or even that the reduction in ice is unusual? After all, the earth is warming out of the little ice age and has been for about a century and a half now.
Lets take a look at what climate science calls the gold standard in temperature reconstructions. It is derived from the GISP2 ice cores taken from Greenland, above the Arctic Circle. As you can see, if you have any graph reading skills at all, it is cooler at present than it has been for most of the past 10,000 years. You can also see temperature changes far greater than any we have seen and in shorter periods have been happening periodically throughout this interglacial period both to the warmer, and to the cooler.
So we can see from the temperature reconstruction derived from the GISP2 ice core that the present is cooler than it has been for most of the past 10,00 years with the except of the little ice age which the earth is still warming its way out of...as you can see, we haven' even reached the temperarue it was at the onset of the little ice age. Now I can look at that graph of temperatures over the past 10,000 years and be pretty sure that if I looked at a reconstruction of what the ice looked like in the arctic over that same time, I would see that with the exception of the little ice age, there is probably more ice in the arctic regions now than there has been for most of the past 10,000 years... You being a denier though, I doubt that you would reach the same conclusion, so lets have a look at some published science regarding what the ice in the arctic has looked like over the same period.
This particular graph showing what the ice in the arctic has looked like over the past 10,000 years is from Stein, et. al. and was published in the Journal of Quartanary Science. As I predicted, it shows that the ice in the arctic region is greater now than it has been for most of the past 10,000 years. As you can see form this graph, there have been periods when all of the sea ice was probably absent..8000 years ago, and 9500 years ago respectively...and throughout the past 10,000 years, there was less ice than there is now except for the period of the little ice age...
But lets not stop with a single paper...here is another, also published in the Quaternary Science Review by Perner, et. al. in 2018...note that I am providing fairly recent papers as opposed to the crap you are providing which is nearly 20 years old. again, as you can see, with the exception of the little ice age, there is more ice in the arctic regions now than there has been for the past 10,000 years. I can provide more, but there is probably no amount of actual science that could convince you that you have been lied to. The bottom line is that while the ice is melting in the arctic, it is nothing unusual, or unexpected....and certainly not attributable to us...as you can see, the ice started shrinking at the end of the little ice age and continues to this day and since we aren't even as warm as it was at the onset of the little ice age, we should expect the ice to continue to melt...all by itself with or without human beings producing CO2...
