“Why it is not obvious to all that the climate has been changing (due to natural causes, whatever they are) for hundreds of millions of years … is a mystery.” – Ray Kraft
Even though our planet was warmer than today during the Eemian Period, and even though there were no factories belching anything into the atmosphere at the time, author Conor Purcell, PhD. vainly tries to use the Eemian Period to scare us into submission.
In his commentary below, Ray Kraft demolishes Purcell’s arguments.
Examining (and destroying) alarmist claims
By Ray Kraft
In an article entitled “Climate science looks to the future – And it’s not pretty,” author Conor Purcell, PhD., predicts we are seeing a replay of the Eemian interglacial circa 120,000 years ago when it was a few degrees warmer than now and sea level was 6 – 9 meters higher than now.
He asserts that the warming during the Eemian and today’s warming is / was caused by higher CO2 levels.
However, he fails to account for the cause of the allegedly higher CO2 levels 120,000 years ago (he also does not specify the levels). It could not have been caused by us burning fossil fuels.
He mentions the ice age before the Eemian interglacial as 120,000 to 200,000 years long, but says little more than that about it. He does not say how far sea levels fell during that ice age.
He says nothing about the causes of the end of the Eemian or the onslaught of the most recent ice age, or the causes of the rapid global warming that started circa 12,000 years ago, which obviously could not have been caused by humans burning fossil fuels. I have read that some anthropologists think the last ice age had reduced the global human population to fewer than 10,000 circa 12,000 years ago.
He says nothing about the recurring cycles of global warming and cooling over the last 50,000,000 years, or why the geologically rapid cycles of warming / cooling suddenly began circa 50 million years ago and have continued since, with a long slow cooling trend over 50 million years.
He focuses on the near future – predicting that rising CO2 levels will cause temps 2 to 6 degrees warmer than now by 2100 with much higher sea levels.
But says nothing about accumulating ice in the Arctic and Antarctic now.
Says nothing about the next ice age that will follow, assuming the natural cycles of the last 50,000,000 years continue.
Why it is not obvious to all that the climate has been changing (due to natural causes, whatever they are) for hundreds of millions of years, it didn’t begin with us, it isn’t our fault, we can’t make it stop, our only option is to expect cycles of global warming and global cooling and adapt to climate change as it changes . . . is a mystery.
Of course, if climate change is our fault and we can make it stop, that has ENORMOUS political value.
If climate change is natural and all we can do is adapt, that has ZERO political value.
