Saber Tooth Tiger and the Woolly Mammoth, Pratical Guide

What would we do without it, CO2 runs our world. CO2, mmmm plants love the stuff. Grow big and strong plants with lots of CO2. What do you think they do in a greenhouse? No CO2, dead world. Why do you think we and every other form of life on plant Earth are called carbon life forms? Strange name, isn't it.

When you are an engineer, as am I, one thing to do is check the boundary conditions. For example, halve the suns output and decide what would happen to Earth's temperature. Then double it, and decide what would happen to Earth's temperature. Then add or subtract all the CO2 your little heart desires and rerun the assumptions and decide the result. Hmm, get the point yet?

Following that, to check your computer models, roll back time. Say to 1500 or even to 0 BC and run your models forward and see if they accurately predict the known temperature record, no not the faked one that shows it's flat, the real one that shows the little ice age and other features. If not then don't let them see the light of day until you've fixed the models.

The Earth has been warming since the end of the little ice age, about 1,700 AD, with temperature going up and down along the way.

Another thing for a budding student of climate studies to do, a few hundred years is nothing to the planet, which has been around for billions of years. We know enough about the climate paleontology to know that ice ages have started to cycle every 100,000 years, with a brief period of interglacial of about 10,000 years. The current interglacial, the Holocene period is about 12,000 years old today. The one thing certain the next glacial ice age is coming, and New York will be under several thousand feet of ice. At least there will be that to take consolation in. It's not a matter of if, it's a matter of when. Ask yourself, "I wonder what SUV the Saber Tooth Tiger and the Woolly Mammoth were driving in 10,000 BC. You have watched the movie Ice Age, haven't you?

Prof Bob Carter has some lecture videos on youtube if you care to watch.
