A long and interesting discussion followed Venusian Mysteries. One commenter posed an excellent thought experiment: Consider Venus with its existing atmosphere, and put a totally opaque enclosure (to incoming Solar radiation) around the entire planet at the average location of present outgoing long wave radiation. Use a surface with the same albedo as present Venus for [...]

The surface of Venus is around 730K (457°C) – why is it so hot? Although there is still much to learn about Venus the basics have some simple explanations. Energy Absorbed from the Sun While earth is 150M km from the sun, Venus is only 108M km away, a ratio of 0.72. The “solar constant” [...]

On Lunar Madness and Physics Basics, one commenter asked a very good question in response to a badly phrased answer from me. He originally asked: You agree that if earth had 100% nitrogen atmosphere (a non greenhouse gas), the “average” temperature of earth would be different (I’m not entirely sure it wouldn’t be lower) from [...]

On a couple of unrelated articles on this blog, people have been asking questions about the moon. This is because a lot of people have read an article called A Greenhouse Effect on the Moon from www.ilovemycarbondioxide.com that makes some confused claims. The article starts: We’ve been told that the earth’s surface is quite a bit [...]

Checkout the more comprehensive: The Sun and Max Planck Agree – Part Two For regular readers of this blog, this post adds nothing new. Think of it as placeholder – a link to send people to when they ask about this basic subject. A very handy aspect of climate science is that we can easily differentiate between [...]
