text: It will be warmer due to absorption of long-wave infrared by greenhouse gases.\n\nYour question could just as easily be worded as "How does the greenhouse effect work?" To see an excellent explanation and illustrations of how greenhouse gases absorb infrared energy go to:\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html\n\nThe principle operates the same here on Earth as it does on Venus, it is just that Venus has some other effects that have exacerbated the atmospheric content of CO2, along with its much higher atmospheric pressures. Most of the Russian Venera probes to Venus lasted about an hour on the surface, at a temperature of about 850 F. and pressures equal to about 3000 ft below the sea (90 times earth's atmosphere).
