“Apocalyptic mythology has always made fools of normally bright people”.
Fascinating report on the possible origin of Covid:

Note: Martin Seligman in ‘Learned Optimism’ noted the post-WW2 reaction in US academia to “Boosterism”- the enthusiastic promotion of something. Academics came to believe that pessimism was deep, while optimism was shallow.
Science facts: Keep the larger paleo-climate context in mind in order to understand the “true state of things.” Wendell Krossa
Some interesting research has shown that the previous interglacial, the Eemian of some 130-115,000 years ago, was at least 1 degree C. warmer than our current Holocene interglacial. Others, like Patrick Moore, say the Eemian was 2-4 degrees C warmer. Both of the previous two interglacials were warmer than our Holocene interglacial. We are on a long-term cooling trend.
Add here that the warmer interglacials that punctuate glaciations also experience repeated episodes of warming and cooling periods. There is no such thing as stasis in climate. There are numerous natural shifts in climate that occur in cyclical patterns over decades, centuries, and millennia. Before blaming humanity, we ought to educate ourselves regarding these facts.
Over the 10,000 years of our interglacial there has been a long-term cooling trend with regard to the warm periods of our interglacial. The Holocene Optimum (roughly 7000 to 3000 BCE) was at least 1 degree warmer than our current modern warm period. Some say the Holocene Optimum was 3 degrees C warmer but that may refer to different local situations during that time. And the Roman (250 BCE to 400 CE) and Medieval (950 to 1250 CE) warm periods were at least 1 degree C warmer than today.
Over the last 5000 years since the Holocene Optimum ended, we have been on a long-term cooling trend, the “Neo-Glacial Period”. Each warm period is now cooler than previous ones. We are on a long-term climate trend that is declining toward a cooler future, not warmer. Cooling, not warming, ought to be our greater concern. After all, 15-20 times more people die from cold every year, than die from warmth.
Qualifier: Being a polite Canadian (“Sorry, eh”) I am conflicted over using potentially offense-inciting terms like “insanity, lunacy, craziness”. But how else to describe what is happening with climate alarmism today? Sorry, eh. But…
Stand back and observe...
Stand back for a moment and survey the public scene today, notably the alarmist movement that hysterically claims we face an existential “climate crisis”. Try to get some sense of the profound irrationality that has possessed so many people, irrationality that stems from the apocalyptic-porn narratives that now dominate the worldviews of many scientists, celebrities, politicians, and members of news media. A daily outpouring of madness.
The very basic food of all life- CO2- has been in historically short supply, at dangerously low levels in the pre-industrial era. Some 20,000 years ago it even dipped below 200 ppm, down to 185 ppm, just 35 ppm above the level at which all plant life dies- 150 ppm. Life on Earth was suffering from a long-term “CO2 starvation era”. See Patrick Moore’s excellent treatment of this paleo-climate history in his latest book “Fake Invisible Catastrophes and Threats of Doom” and his excellent essay on the same topic at-

Now that CO2 has slightly recovered to 400-plus ppm, the planet has greened immensely, adding green vegetation equal to twice the size of the continental US over the past 40 years. However, CO2 is still far below the healthier levels of most of past history when CO2 was in the multiple-thousands of ppm. Life thrived during such eras. CO2 was at 7000 ppm during the Cambrian Explosion when the proto-forms of all modern life emerged. Read the rest of the opening comment here
