WHO DO YOU BLAME FOR CLIMATE CHANGE SEVEN MILLION YEARS AGO/

According to a recent report, scientists now believe that the Sahara desert formed seven million years ago due to climate change.*

A large sea called Tethys formed some 200 million years ago between what were then the African and Eurasian continents. Then, about 100 years later, the sea began to contract, and about 5 million years ago it wound up divided into the current Mediterranean, Caspian and Black seas.

Scientists found that, when Tethys was its old, large self, it facilitated rainfall over North Africa due to temperature differences between its warm water surface and cool surrounding land. These temperature differences allowed moisture fro the Atlantic to be carried over the area. When Tethys began to shrink, it created a climate change which resulted in much less rainfall on the Sahara area, thus ultimately causing a desert.

United Nations reports now assert that climate change is occurring due to human activity. global warming being man-made. So, who caused the climate change that created the Sahara desert? If the age of its formation is correct, it arose about the time that early mankind allegedly evolved. Do we blame them or chimpanzees?

In a way, water created a climate in North Africa, and water also changed that climate. Rainfall resulted from temperature differences involving the sea, and rainfall ceased when the water in the sea contracted. It is thought that Tethys contracted when squeezed by the two continents approaching each other. Who do we blame for that?

As I write this, most of the United States is buckling under an invasion by the arctic vortex for the second year in a row. It is bringing heavy snow, sub-freezing temperatures and high winds--all abnormal compared with historical data. The only warming I am experiencing is micro-warming belching from a much burdened home furnace as I squint out the window at a premature, autumnal winter scene.
