Snow in the Era of Global Warming

Is anyone curious to know what the global snowfall trend was in this era of “extreme” global warming? I was. Luckily NASA covertly provides us with all the necessary data to figure this out.
I downloaded all available monthly images from 1980 to 2020 (inclusive), such as the one shown below, then I converted the pixel colors back to data using the provided scale.
The error margin is small and time-persistent and so this is a clever way to extract a rich dataset which I haven’t been able to find anywhere else.
As far as I know, you will not see this anywhere else. All other snowfall or snow-cover datasets are limited by region or date and so researchers reach the wrong conclusion!
Here is the result of my quest:
2.773 -> 2.854 is +2.90 percent
Snowfall has increased by nearly 3 percent over the last four decades!
Units are milligrams per square meter per second.
Let’s also see how this breaks down by North and South hemisphere:
Northern hemisphere (above)
2.722 -> 2.468 is -9.35 percent
Southern hemisphere (above)
2.824 -> 3.239 is +14.71 percent
The southern hemisphere increase in snow more than compensates for the northern hemisphere decrease in snow. This led to an overall increase of 2.9 percent in snow during our great era of global warming!

Having spent 17 winters in Lassen County I can attest to see the diminished snow from then to now.
This is a drying trend. Been going on since the glaciers retreated. The Sierra high desert used to be dotted with huge deep lakes. Nearly all gone.
