I live in Maine. Thank God we haven’t gotten as much of the “polar vortex” as other states … but we’ve had our share. It’s cold.
But overall, temperatures in Maine haven’t been going down. They’ve been going up. Here’s temperature anomaly for Maine for each month since January 1895, showing how much colder or hotter than average each month was:
That red line is a “trend” line. It’s just an estimate, mind you, but it’s based on math, and it passes all the mathematical tests. It says: overall, Maine has warmed since 1895 by about 3.2°F (1.8°C).
That’s global warming come to Maine, which makes it local warming. It’s called “warming” because it’s a trend in temperature which is going up.
Pay attention, dumbass! Trend. Temperature. Up. That’s global warming. It’s not the fluctuations, it’s not the weather, it’s the overall trend in temperature going up. Not a “pretend” trend, like “boy was it cold yesterday!” A real trend, that doesn’t just use math, it passes the mathematical tests.
Not all seasons have shown the same warming. Here in Maine, when we look at the temperatures for only the winter months (that’s December+January+February when it comes to climate) we see this:
Winter temperatures have risen (on average) fully 5°F (2.8°C), faster than the yearly averages. Again, that’s a trend in temperature going up.
Then there’s this thing called climate change.
I notice that in Maine, in spite of the warming trend in winter temperature, some of the coldest winter months on record are in the later part of the record. Coldest of all was December 1989 at nearly 14°F colder than average, and that’s not a single December day, it’s the average for the entire month! That’s one wild and crazy cold month. Even as recently as 2015, we had a February nearly 10°F below average (again, not for just a day but averaged over the whole month). Is that crazy or what? But the hottest winter months have also been recent. What’s going on?
The trend represents how the average is changing. But it doesn’t tell us anything about the fluctuations. Are they getting bigger, or smaller, or staying about the same? Is there any change in the way temperature fluctuates, independent of whatever changes its average might show? If so, it won’t be global warming (or any warming for that matter), it will be climate change.
You see, climate is not the same as weather, and climate change is not the same as global warming. And global warming isn’t about the fluctuations or the weather, it’s about the trend.
That overall increase in temperature (be it global, or just winter in Maine) — that’s warming. Any recent tendency to fluctuate more than it used to, to swing wildly from hottest to coldest — that’s climate change. Man-made climate change.
Do you get it? Or do you need my foot in your ass?
