I don't know what else could be the reason. The east coast is about to be pounded yet again with a massive snow storm. Some places are expecting as much as TWO FEET of snow!
Meanwhile, up here in sunny Toronto, we've still only had two snowfalls this winter. I live on the 12th floor of a condo building & cant see any snow from my balcony, just green grass. I have to believe that there's no snow on the ground here & that we're not due to get any because of global warming.
I hate snow. I love global warming. Enjoy your snow America.
