It is always fun to listen to jesters
It is only a problem when people take jokes, exagerrations or lies seriously without scrutinizing them, abusing them for their political agenda – all sides.
Yes i know it is boring to listen to reasonable explanations. You can now stop here.


True that the sun "influences" (lol) global climate, of course. It would be quite cold without it. It would also be cold without the greenhouse effect of the atmosphere, so the latter is not "bad", by whatever definition. Mars has too few of a greenhouse effect, Venus "a bit" too much. Venus' is the earth's twin in a lot of aspects. It is not hot because of vulcans or tectonic activity alone, but because of the CO2 that does not let the heat escape, from the atmosphere. It is enough to make lead melt, at its surface.
Not that i think the earth would experience such a drastic greenhouse-run-away effect, but maybe enough for another evolutional crisis.


On earth, the last summer and the falling dry of some rivers is within the normal fluctuations, a real draught would have been a much different beast.

But the recent global warming of the atmosphere cannot be explained by the sun, since the average amount of its energy has not changed much (which drilling cores in Greenland and Antarctica have shown).

1. Not much change of solar activity or radiance intensity since 1750 (proven by drill cores, plant growth (oak tree rings etc.) and calculations of the earth's precession and orbit around the sun).

2. No climate model can explain the temperature trend of the time after the industrial revolution, without taking the increasing concentration of greenhouse gases into account.

3. More energy from the sun would show in all layers of the earth's atmosphere. Instead there is a cooling in the upper parts of the latter, while lower layers and the surface have warmed. This can up to now only be explained by gases, trapping heat by reflection and warming themselves.

Yes, how boring, i know.
Fun terminated. Schroeder, i hope you are content with my efforts
