Real Global Snowfall Trend

Written by Zoe Phin on December 1, 2021. Posted in Current News

In a previous post, I tried measuring the global snowfall trend over the last 41 years using a pixel color technique because I couldn’t find the original data behind NASA’s public images.

I have now found the higher resolution data needed to find the most accurate global snowfall trend.

The data is from here¹. The results are very similar to the previous result, thus the pixel color technique was excellent.

Here is the real global snowfall trend:

Linear Regression Trend: From 2.855 To 2.949 is +3.292 percent

Global snowfall has increased by over three percent in the last four decades.

By hemisphere:

Linear Regression Trend: From 2.771 To 2.538 is -8.415 percent

Linear Regression Trend: From 2.939 To 3.358 is +14.232 percent

So, while snowfall has reduced slightly in the northern hemisphere, it has increased significantly in the southern hemisphere.

That’s all. Enjoy 🙂 -Zoe
