Good.<br /><br />The surface temperature is, as you rightly point out, not dependant upon the amount of sunlight, but it is an artefact of the pressure of the atmosphere.<br /><br />Here is your homework.<br /><br />Assuming the surface temperature of Venus is ~480C (~900F), replace the Venusian atmospheric components with that of Gaia (78% Nitrogen, 21% Oxygen, 1% others (primarily Argon)).<br /><br />Calculate the expected surface temperature of Venus at 92 bar with Gaia'a atmospheric mix, assuming solar irradience of 2,614 W/m2.<br /><br />If you are a good student, you will conclude that the surface temperature of Venus would actually <b>increase by 200C</b>, wouldn't you?<br /><br />Nothing like ranting in ignorance, is there?Kaboomhttps://www.blogger.com/profile/05678065310675687503noreply@blogger.comtag:blogger.com,1999:blog-5649264476699871612.post-78565479443105610002009-11-15T10:27:58.350-08:002009-11-15T10:27:58.350-08:00Does anyone here actually have substantive underst...Does anyone here actually have substantive understanding of the physics? Blackbody equilibrium temperature, the Steffan Boltzman equation, the atmospheric transparency to visible light, the opacity to infrared, etc. Venus has a surface temperature of around 900F despite having a effective blackbody equilibrium temperature of only about 135F. So, DUH, it's surface temp is not because it is too close to the sun. Unless you really can quantitatively deal with these subjects, and more, you are just ranting in ignorance.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5649264476699871612.post-38270891963175275822009-10-27T09:15:44.577-07:002009-10-27T09:15:44.577-07:00Runaway Greenhouse effect is one of the most hilar...Runaway Greenhouse effect is one of the most hilarious doom prophecies ever. Venus's atmosphere is a product of being too close to the sun. DUH! The fact that many warm ages have come and gone with CO2 levels 20 times higher than we have today without ending all life on Earth pretty much slams the door on the Runaway Greenhouse effect. <br />What is even funnier is when some warmists propose that there are no aliens in the sky because Global Warming boiled them all. You can add Intergalactic Genocide to the trumped up charges against an industrial society. It gives me no end of pleasure to imagine the impending headline: Global Warming Killed the Aliens.

Sadly, the "precautionary principle" will remain enshrined in our consciousness as something with actual merit, like a proven vaccine. We can look forward to more H1N1 panic-demics and Y2Ksterias because, although the "scientists" were profoundly wrong, they had only our best interests at heart.Zookeeperhttps://www.blogger.com/profile/07454330013436283393noreply@blogger.com
