This is what our street looked like March 20, 2011 from the corner. The snow and ice were starting to melt, but there was plenty of snow still in the street.
Here's t our street looking to that same corner yesterday, March 4, 2015. The middle of the street had large swaths clear to the pavement with hard ice on the sides. (There was a slick surface in the morning as the overnight temperatures dipped below freezing and met the street surface, damp from melting ice.) At the corner (you see in the picture above) the pavement was clear and dry.
Below is our front lawn. Usually at this time of year it's still well covered with snow. A few patches might be bare under the tree. Toward the middle or end of the month the sidewalk and front might start to clear and we get a little excited. Then comes another several inches of snow to cover everything back up.
No, this one year doesn't prove global warming is here and real. However, this year, plus all the weird weather around the world for the last 20 years, plus the studies of many, many climate scientists, does.
Denying climate change and human's role in climate change is like saying, "The speedometer is wrong" when you're going 90 miles an hour toward the cliff. You're either drunk, delusional, or you have some vested interest in not believing. Could the speedometer be wrong? It does happen, but we can also see the landscape going by our windows really fast. And maybe they've put a giant water balloon at the edge of the cliff so we will stop safely. But slowing down seems like a much more prudent approach. Even if you'll be late for your appointment.
