| #3 log_cal I agree that the earth absorbs and radiates; it simply does not do so as a black body. In fact, the absorbtion, for example, depends on all kinds of things; ice/snow cover, cloud cover, type of soil - even more complex that that is that the reflectivity of ice/snow varies greatly depending on its age (new snow reflects very well, ice with a dirty surface doesn't reflect well at all) |

| #2 mhw... and the data that supports your statements and your assertion that the earth 'does not absorb or radiate' solar radiation come from where??? You've proven that a person does not need to espouse global warming to be a supporter of it, and that a rhetorical comment on scientific matters that is itself an antethesis, is definitely not an indication of intelligence. |

| #1 Direct measurements of the sun's radiation have only been made for about 30 years and the first 10 of those years were with instruments that weren't all that good. The increment between the peak and the trough is thought to be about 00.2%. If the earth were a atmosphere-free black body with no magnetic field, this would correspond to a temperature change of essentially nothing. Of course the earth has an atmosphere and neither absorbs nor radiates as a black body and has a mag field so no one really knows what the impact of the solar variation is. There are a lot of theories. |
