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 above, 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:
Units are milligrams per square meter per second.
Let’s also see how this breaks down by North and South hemisphere:
SH increase in snow more than compensates NH decrease in snow. This led to an overall increase in snow during our great era of global warming!
That’s it. Enjoy 🙂 -Zoe
