A news article in the Gannett Wisconsin newspapers recently told of the WI DNR removing all references to "climate change" from their web sites. A comment that someone placed on-line under the article asked "The climate has changed many times - why is this change different from all the others?"
I responded:
On the chance that your question is sincere, I understand that there is one primary difference between the current change and previous climate changes. SPEED. For example, when the "Wisconsin" glaciation of 20,000+ years ago was melted back by warming, the climate change took place over 4,000 years or more. The current warming of the planet, which is roughly on the same scale, is taking 200 years or less.
Another difference is that humanity used to have more mobility. When the climate in Africa became too stressful 75,000 years ago, we left and moved out to Europe, Asia, and Americas. Now, we have all these lines drawn on the map that make it impossible for people whose agriculture has been destroyed by the climate changes to move to someplace better.
And, of course, a big difference now is that we humans exist and are capable with our technology to throw the planetary climate out of balance. Unfortunately, we humans are not capable of working together to solve any problems like that. It's like we are children playing with matches.
Did that help?
