Remarkable how in the 1910s and 1920s we had uninterrupted stretches of extra winters decades in a row, but now early spring dominates. Clear evidence of global warming.
That's a huge insight to take away. Nevertheless, we still have climate-denier groundhogs consistently predicting winter and being wrong about it ( cough Phil cough ). Hopefully, this site helps shine a light on these unscientific groundhogs.
If I'm not mistaken, Phil's "predictions" are just written down ahead of time, while other groundhogs have to actually move towards a sign that says "early spring" or "long winter".
I wonder if there is an easy way to tell which groundhog uses which method and if the groundhogs are more accurate about climate change than the humans.
