With this much solar activity how does it affect global warming?
you can watch Newt debate Kerry live on foxnews.com right now.
I doubt either will mention the sun that much, it hasn't made it into the viewpoint of the body politic yet thanks to our incompentent, agenda driven media.

My understanding is that sunspots, since they are cooler than the average temperature of the sun's surface, would decrease radiation from the sun where the spots are, but there are always bright areas in the active regions (near the sunspots), called faculae, which are brighter and produce more radiation than average. The net effect is a slight increase in total solar irradiance during active periods. This difference is noticed during the 11-year solar cycle but that difference is very small. He's talking about an average increase in sunspots over several solar cycles, which could be enough to warm the earth appreciably. The sun is currently at the low point in the solar cycle, not that much happening right now.
That would somewhat explain the Maunder minimum, but not the major ice ages, which were probably due to other factors.

Who cares. The question is, how does this affect ham radio? I wonder if this will hold up until the 11-year cycle hits a max in about 4 years? Just imagine an ionosphere E-F-F1-F2 layer where even 10 meters is open all over the world for 18 hours a day. Or 15 meters (my favorite bad) open all over the world 18 hours a day. I hope I'm ready to go when it hits a max.

Quote:Warming On Jupiter, Mars, Pluto, Neptune's Moon & Earth Linked to Increased Solar Activity, Scientists Say
IN CASE YOU MISSED IT...
Bright sun, warm Earth. Coincidence?
By Lorne Gunter
National Post
Link to Article
Monday, March 12, 2007
Quote:I published a quiz elsewhere that bears repeating in our current hyper-charged environmental debate: Quick, which is usually warmer, day or night?
And what is typically the warmest part of the day? The warmest time of year?
Finally, which are generally warmer: cloudy or cloudless days?
If you answered day, afternoon, summer and cloudless you may be well on your way to understanding what is causing global warming.
For the past century and a half, Earth has been warming. Coincidentally (or perhaps not so coincidentally), during that same period, our sun has been brightening, becoming more active, sending out more radiation.
Habibullah Abdussamatov of the Pulkovo Astronomical Observatory in St. Petersburg, Sami Solanki of the Max Planck Institute for Solar System Research in Germany, Sallie Baliunas and Willie Soon of the Solar and Stellar Physics Division of the Harvard-Smithsonian Center for Astrophysics and a host of the rest of the world's leading solar scientists are all convinced that the warming of recent years is not unusual and that nearly all the warming in the past 150 years can be attributed to the sun.
Solar scientists from Iowa to Siberia have overlaid the last several warm periods on our planet with known variations in our sun's activity and found, according to Mr. Solanki, "a near-perfect match."

I would also like to see it, since I have telescopes that are designed for looking at details on the sun. Seems like whenever there's activity its cloudy.

I think this is a sunspot maximum year, isnt it? If so, the same extreme activity has happened before about 200 years ago, and was followed shortly after by a absence of sunspots.

The Bad Astronomer's take on solar warming. Obviously he is on the side of global warming is not due to solar activity side, but he brings up some important points. This is the guy who debunked the moon hoax arguments.

Someone thought the moon was a hoax? What an idiot! /sarcasm ;-)

Since we want to go to Mars and mars has global 'warming' taking place, I think it would be very logical to send Al Gore on the first Mars mission so he can save the martians from Global "warming" and the melting ice caps on mars.
If the government doesn't fund this mission, I wonder how much worth of donations would could find to make this happen?

George Bush is the one that wants to go to Mars. Let's send him there.
