Uncompressing the Vertical Axis
This is a chart with a vertical axis that covers the normal extremes of hot and cold here on Earth, that is, it goes from -10 to 110. It's in Fahrenheit degrees which is the form of temperature measurement used by the only nation to have had its citizens walking on the moon. The average temp ranges between 56.7 and 58.1. Not very scary, but relatively accurate. Yet you never see the temperature over 135 years charted with a reasonable vertical axis. It's almost always an anomaly chart from some supposed average and the increments are in tenths of degrees over a range of 4 to 8 degrees. With that compressed axis, it looks like we're heading for a roasting. We're not.
I continue to be a luke warmer. It is getting a little bit warmer (Thank God) after the Little Ice Age; and the rise of CO2, partially from fossil fuel burning by humans, has been a part of the cause of that rise. But it is a tiny rise in average temperature and it is not going to do anything but be nicer out more often, especially at night. And the added CO2 will green up the place as those levels begin to creep back up to the much higher levels that existed when most modern plant species evolved. It's like a win-win.
There is no reason in the world to freak out and destroy already precarious economies. No reason at all.
