Or cooler than "with an atmosphere but a magical kind of atmosphere that does not have greenhouse effect"? or "cooler than they are now" (which is a meaningless comparison and presumes that there is a greenhouse effect, and you can't use an assumption as evidence to support that assumption).<br /><br />I can't even guess what you mean. You seem to be saying that without a greenhouse effect they would be a) warmer and b) cooler.<br /><br /><br />Mark Wadsworthhttps://www.blogger.com/profile/07733511175178098449noreply@blogger.comtag:blogger.com,1999:blog-1141932539860553199.post-73439480898672194342021-05-02T16:56:55.852+01:002021-05-02T16:56:55.852+01:00If there was no atmosphere there would be be no la...If there was no atmosphere there would be be no lapse rate and they would be warmer, if there was no greenhouse effect they would be cooler, so no negative GH effect.Dinerohttps://www.blogger.com/profile/14632385731642361211noreply@blogger.comtag:blogger.com,1999:blog-1141932539860553199.post-9695844330338226042021-05-02T16:12:16.902+01:002021-05-02T16:12:16.902+01:00Din, in real life, that's correct.

A lot of the hits are pure propaganda, so you have to filter it all down to things that accord with basic maths, basic physics and common sense. If you get sensible answers, then that's good enough for me.<br /><br />Re Mars, grow up. Mars has about twice as much CO2 as Earth has in CO2 and H20 combined. Yet the 'official' greenhouse effect is no more than 5 degrees (against alleged 33 degrees on Earth). If you want to scale that down to CO2-caused greenhouse effect on Earth, the answer is "too small to calculate".<br /><br />Re mountain tops, this is a glaring Achilles Heel of AGW theory. They get as much sunshine as at sea level, and while there is less CO2 above them than above sea level, there is no 'greenhouse effect', there is a *negative* greenhouse effect, they are cooler than Earth's effective temperature.Mark Wadsworthhttps://www.blogger.com/profile/07733511175178098449noreply@blogger.comtag:blogger.com,1999:blog-1141932539860553199.post-8139642533283243372021-05-02T13:26:41.151+01:002021-05-02T13:26:41.151+01:00What search engine do you use.

On Google I often get the answers to these type of science questions quickly on the first page. <br /> Mars is cool because it has a thin atmosphere without the water vapour that Earth has. Water vapour being the greater GHG. and the CO2 GH effect is measurable for Mars. <br /> Not sure what you mean about mountains.Dinerohttps://www.blogger.com/profile/14632385731642361211noreply@blogger.comtag:blogger.com,1999:blog-1141932539860553199.post-11554641234575109492021-05-02T12:27:29.866+01:002021-05-02T12:27:29.866+01:00Din, yes, that is the interpretation which is lead...Din, yes, that is the interpretation which is leads to a more plausible end result. <br /><br />But fails on the facts.
