2] Right, but what's your point?
. . a] Where did I say anything different?
. . b] The GHG mechanism revolves around IR radiation emitted from the earth's surface, not visible light from the sun. The false claim is that absorption of IR radiation from the earth's surface by CO2 in the upper troposphere and higher will somehow result in that IR getting back down to the surface. But it can't, because it is absorbed by water vapor and CO2 long before it gets there, as Angstrom proved, and re-radiated upward. c] So all that happens with increased CO2 is that the final emission altitude rises and the characteristic temperature of the emission falls, restoring the thermal equilibrium. The effect on the earth's surface temperature is derisory.

4] Right, because there is no credible empirical evidence that droughts are any worse now than they have been for thousands if not millions of years.
5] No, they are not convincing because they can't make reliably accurate predictions.
1] I disagree with your claiming more science knowledge that I have. See below for the proof.
2] . a] Well, you may not have said that the energy that reaches the surface of the Earth from the sun is mostly in the form of visible light. However that is just a scientific fact. If you don't know this fact, then you are lacking in your scientific knowledge.
. . . b] Well, again you're showing your lack of scientific knowledge. When a molecule absorbs heat=infrared light it doesn't reradiate it in the same direction. If it did it would have little effect as you say. However, the direction it is reradiated is totally random. So, is rediated down as much as up.
. . . c] The GHG story is that the energy reaches the Earth's surface in the form of visible light from the sun. Over the course of a day or a year the energy either heats up the Earth or it is sent somehow back to space. Energy is conserved, it can't disappear. Either it leaves, or it heats things, or it makes something move faster.
. . . So, the heated up earth/dirt/rocks/oceans is hotter which causes it to radiate more infrared light upwards (down too but it can't go far before it is stopped and sent up, eventually.
. . . So, the infrared light is absorbed by CO2 in the air and reradiated up, down or sideways. If the energy is trapped at any altitude by any process it can't just be there. It must heat up the air at that altitude. This not happening much. We know this because we can feel the heat of the sun and so we know that it is enough to heat things up, like a piece of metal in the sun. Therefore, the fact that we don't see the temp of air at many altitudes heating up 2 dec. C per day, everyday, all summer, proves that the heat is mostly escaping out into space. And some is heating the ground and the oceans. But, mostly it must escape to space. It simply MUST! Again you are showing your lack of scientific knowledge.
. . . Lurkers, frankly I'm not sure why the infrared light tends to be sent up more but it must be because otherwise as I just showed it would either heat up the air or heat up the dirt & oceans. He doesn't want to have it heat the dirt and we can agree it isn't heating the air that much, so it must go up more than down.
. . . However, some can be sent back down to be causing the dirt to be heated a little year after year.
. . . Anyway, as we go up in altitude the concentration of CO2 is reduced as the air pressure is reduced. Therefore, the level where the CO2 stops all the infrared rises, and this reduces the amount of the energy that finally escapes out into space. So, less energy escapes, so more stays in the air or in the dirt/oceans/etc. And, that more energy must show up as heat, which we see as increasing temps. It isn't a lot, but the small change heats the Earth year after year. BTW --- the Earth is never in temp. equilibrium because the temp does up and down during the day and during the months. The ave. temp. changes every year a little. Sometimes it has changed going down for decades, sometimes it has gone up a little each year for decades, and sometimes it has done little for decades, but it is always changing at least a little.
