I have a few comments to the June 30 letter [“We must all act to stop climate change”] about global warming by Mr. John Dworak.
I don’t know where published numbers are from, but from example, I have doubts that we know temperature 129,000 years ago. Different information is available in a span of 4,000 years in the Museum of Nature in Tupper Lake.
There are three periods significantly warmer, in which there was abundance of food and culture and arts were flourishing. In the colder interval in between the first and the third warm intervals were hunger, misery and decay of culture.
The first episode was the Greek culture, second, the Roman culture (Coliseum) and third was relatively close by Renaissance (Michelangelo).
After the Roman Empire, there was an interval of such a cold that hungry Vikings invaded Paris (885 AC). After the Renaissance (about 1250 to 1550 AC) was the Little Ice Age, when it was so cold the ocean water decreased about 4 degrees F in Europe and eight in Africa. There was total hunger — starvation due to snow descent — for example, 300 feet in Switzerland.
France lost 10 percent of its population, Estonia one-third and Iceland half due to livestock dying from lack of food and because fishing from Iceland was not possible for several months a year due to freezing of ocean water around Iceland shore.
Misery of the Little Ice Age started to improve with warming at the beginning of the Industrial Revolution (about 1780 AD), and this warming is slowly continuing even now. Present temperature is still colder than in the previously mentioned three intervals.
Do you wish us back to misery before the Industrial Revolution?
