Pope Francis: The encyclical ‘Laudato Si’ issued in 2015 motivated many people to take action on global warming, but governments, the pope said, have lagged far behind. In June 2020," he issued guidance for carrying out his climate encyclical that included calling on Catholics to divest themselves of investments in fossil fuel companies. It's not just social justice issues, and not just environmental issues, It's the cry of the Earth and the cry of the poor, all coming together. The encyclical names this 'integral ecology'."

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?

Ken Haapala, SEPP, The Science and Environmental Policy Project: Richard Lindzen’s paper summarizes what we know with reasonable certainty, what we suspect, and what we know is incorrect about climate change, the greenhouse effect, temperature trends, climate modeling, ocean chemistry, and sea level rise. Key parts included: 1) The climate system is never in equilibrium. 2) The core of the system consists of two turbulent fluids interacting with each other and unevenly heated by the sun. 3) The two most important substances in the greenhouse effect are water vapor and clouds, which are not fully understood. 4) A vital component of the atmosphere is water in its liquid, solid, and vapor phases and the changes in phases with immense dynamic consequences. 5) Doubling carbon dioxide, (CO2), creates a 2% disturbance to the normal flow of energy, which is similar to the disturbance created by changes in clouds and other natural features. 6) Temperatures in the tropics have been extremely stable. Temperature differences between the tropics and polar regions are extremely important.
