Walter Aeberli, Swiss engineer and lover of nature and adventures in the outdoors: This is his communication to a life-long friend about an article in the Neue Zuercher Zeitung by Marcus Schaer: "Die Klima-Apokalypse wird wohl nicht ganz so düster. Dafür, und das vergessen wir gerne, droht uns anderes." This article quotes books published in 2020 by Michael Shellenberger and Bjorn Lomborg explaining that global warming alarmism has gone far beyond reality and is preventing countries from solving pressing real problems. There are photo examples from all over Europe of a robust climate.
Kenneth Richard, author about man-made global warming for Principia Scientific and No Tricks Zone: Studies of the Earth's average temperature from North Pole to the Equator to the South Pole from around 1900 to 2020 suggests that there has be no significant change of this global average number. But alarmists have many believing that use of fossil fuels are causing catastrophic man-made global warming heading to an irreversible temperature tipping point. Even generally rational scientists claim that the world is heading toward a temperature tipping point that can only be avoided by drastic reduction in use of fossil fuels. Our modern world is threatened by bad decisions.
George Chilingarian, Petroleum Engineer and Geologist: America is under attack. Our freedom and liberty is at risk. The goal is to displace capitalism with socialism. The mechanism is a very elaborate, ongoing, and evil plot to vastly restrict our energy supplies. In so doing America’s political will will be destroyed and our beloved country will find itself joining with the European’s and other countries in pursuit of a single worldwide government under UN control with a vastly reduced world population; a population no greater than a tenth of today’s. The Editor of allaboutenergy.net has inserted (catastrophic) into the title. Carbon dioxide is a greenhouse gas and causes some warming. Water vapor is a much more important greenhouse gas. What we think the author intends to say is that carbon dioxide from fossil fuels is not going to cause catastrophic global warming nor an irreversible climate tipping point.
Jochem Marotzke, Director, Climate Research, Max Planck Institute for Meteorology, Hamburg, Germany: Aren't you worried about thawing permafrost? No, quantitatively the contribution is relatively small. And as a general rule, it always says: Methane is a much more powerful greenhouse gas than CO₂, which is of course true: Overall, methane has a lower greenhouse gas effect than CO₂. Even if the permafrost thaws, it is uncertain how much of the methane really arrives in the atmosphere. Bacteria can convert methane to CO₂. I'm not worried about the methane. I am not concerned about any catastrophic climate tipping point from use of fossil fuels. What does this mean for all the teachers and professors who for forty years have been preaching climate catastrophes from use of fossil fuels? What does it mean for the politicians doing the same?
