Caught Out In Colorado

clipped from wattsupwiththat.com

Both WUWT and Climate Audit had posts regarding the ridiculous WaPo story about snowfall being a result of climate change.

This is a follow up to those posts done by guest contributor Steven Goddard.

One of the  NWF claims about global warming is that snow in the Colorado mountains is diminishing and has become very erratic, as seen in the NWF graphic at left.

In this article I will show that the claim is incorrect – Colorado snowfall has been generally increasing for the last hundred years and that year over year variability has always been extremely high.

In summary, snowfall is increasing annually and we see upward trends in the months of “snowfall season” in Colorado.  Year over year variability has always been very high and may actually be lower in recent years. And, the Colorado mountains no longer have extremely low snow years like they did 80 years ago. By the data, it seems the NWF claims are unfounded.
