How do you call the sun stable? The fact that it is always the same size in the sky means that its output is a constant? Like stated above, look up sunspots for one. The sun's output is extremely variable, and is a large cause of fluctuation.

In total insolation, the sun changes very little during a solar cycle, yes...a few tenths of a percent. However, in some frequency bands, such as the far ultraviolet, energy output can very by several percent. Do feedback effects exist which amplify these insolation changes to cause climate shifts? Many solar physicists believe they do.

Even more compelling is the widespread belief that orbital variations (ala Milankovitch cycles, etc) cause widescale climatic changes. The evidence for this is compelling...but those cycles also only cause very slight changes in total solar insolation themselves. Therefore, if one accepts the "orbital wobble" explanation of past climate shifts (many of which occurred much faster than the one we're now experiencing) then one has to accept such positive amplifications exist.

Just what is the real downside to not polluting so much?

do you still want to breathe in pollution?

It depends exactly what you mean by stable. Is it going to explode or collapse? no. Is it going to massively fluctuate? no. But it will fluctuate. Again, i urge you to look into sunspots.

Each sunspot causes a fluctuation in the sun's energy output. (ie, temperature)

How does health care and sun screen have anything to do with proving there are fluctuations in the sun? I never said it wasn't going to affect anything.

Get a REAL job! Dude, you're too serious.


Well now, that's a bit selfish!

Tom Cruise is stable in his acting output.... but does that make him stable in real life?
