“The history of any one part of the Earth, like the life of a soldier, consists of long periods of boredom and short periods of terror.”
Dr Derek Victor Ager, British paleontologist (1923-1993) in his book: “The Nature of the Stratigraphical Record” (1973)
There are more species around today than at any other time in Earth’s history yet it is widely accepted that, of all biological species that have lived on Earth, more than 90% became extinct long before humans came along. Today, there is an acknowledged rate of ongoing extinctions called the background rate whereby species naturally disappear over time.
Dr Philip Stott, Professor of Biogeography at the University of London, has dismissed alarmist claims about current mass extinctions due to (imaginary) global warming. He said:
“The earth has gone through many periods of major extinctions, some much bigger in size than even being contemplated today.”
“Change is necessary to keep up with change in nature itself. In other words, change is the essence. And the idea that we can keep all species that now exist would be anti-evolutionary, anti-nature and anti the very nature of the earth in which we live.”
In stark contrast to the trivial current background rate, mass extinctions have occurred on numerous occasions throughout geologic time. These are regarded as “natural” cataclysmic events and it is certain that such events will happen again. Those alarmists, making exaggerated claims about current extinctions, need to be aware of the number, magnitude, speed and cause of past extinction events.
