Several folks have asked for information about the Sun's role in warming/cooling. Here is recent summary with lots of links.

I appreciate the work CO2 Science Mag. is doing on this subject. Send them a donation(tax deductable) if you do also, and are able, so they can keep it going, and keep it free for all.

Enjoy!

There has been considerable mention on late nite talk radio - you know who you are! - about the color of the sun. It seems that the past couple of years the sun has gotten much whiter.

With the full moon on the fresh snow the past couple days and nights, there was an opportunity to observe the color of the moonlight, which is related to the color of sunlight, without the overwhelming intensity of direct sunlight.

The observation is this: Artificial lighting has gotten warmer, that is, streetlights are pink to orange and interior lights have tended toward longer life bulbs. Longer life bulbs burn dimmer and considerably more yellowish than older style bulbs. All this is acclimatizing our eyes to a warmer spectrum, taking yellow and pink/orange as normal. Then, when we see in direct sunlight, the sun, which is bright but yellowish, seems whiter than it used to. Those who stare at computer monitors every waking hour are also getting used to a different visual spectrum than natural light.

So, the sun is not getting appreciably whiter, but we are getting unused to natural light.

Huh?

[RightWhale]

That's okay. Some people don't see subtle shades.

[KayEyeDoubleDee]

Huh? An article on the mind-boggling concept that the sun may have an influence on our planet's temperature, and no mention of Sallie Baliunas?

[KayEyeDoubleDee]

I know there are some studies cited above which you think have been debunked...

[blam]

Interesting article, thanks for the ping.

Huh? An article on the mind-boggling concept that the sun may have an influence on our planet's temperature, and no mention of Sallie Baliunas?

I found that odd too, but maybe things are a changing. For a long time she was the voice in the wilderness. Now it looks like she is gaining a chorus.

[KayEyeDoubleDee]

Holy, Moly!! Look what I just found!

This article at SEPP implies that the IPCC generated assumptions to get the results they wanted:

"If what they say is true, then the methodology used is untenable and hence the results are the same. I can't believe anyone would start with an emissions projection, then make an estimate of the relationship between emissions and growth, and finally calculate growth residually. This is the relationship absolutely backward."

But that, apparently, is exactly what the IPCC's economic project did: It worked backward. Formally known as the Special Report on Emissions Scenarios, the official IPCC group set about creating economic forecasts that appear to support average world temperature increases of somewhere between 1.4 and 5.8 degrees over the next 100 years. But the SRES, by imposing emissions forecasts on economic models, adopted scenarios that economists say make no sense.

Assumption #1 in all climate models is that warming will occur, no matter what.

RE: My huh? comment. I think you meant to post that comment here Who Is In Denial? (Global Warming-whose Fault?) instead of here.

[RightWhale]

It belonged right here. The sun is a variable star, but some are seeing a little more variability than is actually occurring. More whiteness equates to a hotter sun, and some think they are seeing a whiter sun. The trend is toward a hotter sun, but the change wouldn't be appreciable or significant in a generation. Millions of years from now the oceans may boil, etc., but we need to look somewhere else for abrupt climate changes, if they are happening at all.

I have been noticing for several years that natural light appears harsher, especially around mid-day, but when I mention it to people, they say "huh"? I don't think it has anything to do with computer screens or the color of artificial lights.

I also noticed a lot more crows than there used to be, but again, people just say "huh"?

So either I am more observant than most or I've lost my mind, or maybe both.

Or just getting old ;-)

I've seen the sun's color appear whiter as well, and my explanation above is what I think is causing that perception. Harsher light, seems like a good observation. Some days the sun is brutally bright. Some of that could be physiological, internal to the observer, the eye-brain connection. But you do notice changes. We don't have crows, but it seems like there are more ravens these days.

Right, though, people just say huh? and go on about their business.

"I have been noticing for several years that natural light appears harsher, especially around mid-day....I also noticed a lot more crows than there used to be...."

Well, build it some up more; throw in a few bloody action scenes and lots of T&A and when it comes out on video I'll rent it. And don't forget the contrails!
