Two weekends ago I attended the Perot Museum of Nature and Science in Dallas and posted a photo of this chart showing Average Global Temperature over the past 630 million years. It shows that temperatures have been far warmer than today for millions – no, hundreds of millions – of years. Several dissenters have pooh-poohed the graph, so I thought you might like to see author Gregory Fegel’s supportive response.
As you can see, average global temperature is now lower – LOWER! – than during most of the last 630 million years.
When someone yells at you that humans are causing a climate emergency, hold onto your wallet.
I used to say it was a ‘hoax,’ but now I think its much more dangerous than that. As far as I’m concerned, the global warming zealots are perpetrating an outright fraud.
Here is Gregory Fegel’s comment:
The graph accompanying the article shows the Earth’s global mean temperature in Fahrenheit, from 625 million years ago to the present.
The global mean temperature (GMT) is currently about 58°F. The natural global warming period called the Eocene Optimum peaked at about 49 million years ago. The National Oceanic and Atmospheric Administration (NOAA) states that during the Early Eocene the GMT was about 9 to 14°C (16 to 25°F) higher than today. So the GMT during the Early Eocene was about 74 to 83°F.
During the Eocene Optimum, little to no ice was present on the Earth. Forests covered most of the Earth, including palm trees growing in Alaska. The warmer temperatures facilitated the intercontinental migration of animals.
The Eocene was a boom time for plants and animals, and it would have been a boom time for humans, had they existed then. Yet the climate alarmists claim that a rise of the GMT of 2 or 3°C will cause a catastrophic mass extinction for life on Earth.
Thank you, Gregory Fegel.
