"For the last 20 to 30 years, we believe greenhouse gases have been the dominant influence on recent climate change," said Robert Cahalan, climatologist at NASA’s Goddard Space Flight Center in Greenbelt, Md.
For the past three decades NASA scientists have investigated the unique relationship between the sun and Earth. Using space-based tools, like the Solar Radiation and Climate Experiment (SORCE), they have studied how much solar energy illuminates Earth, and explored what happens to that energy once it penetrates the atmosphere. The amount of energy that reaches Earth's outer atmosphere is called the total solar irradiance. Total solar irradiance is variable over many different timescales, ranging from seconds to centuries due to changes in solar activity.
The sun goes through roughly an 11-year cycle of activity, from stormy to quiet and back again

I have been saying this all along.

Don't get me wrong, I think that hybrid cars, electric, wind, solar and geo thermal are very smart and very much needed but some people need to smarten the fu*k up and pay attention.

Pretty good info from a VERY reliable source.

it's not earth shattering:

Over the past century, Earth's average temperature has increased by approximately 0.6 degrees Celsius (1.1 degrees Fahrenheit). Solar heating accounts for about 0.15 C, or 25 percent, of this change, according to computer modeling results published by NASA Goddard Institute for Space Studies researcher David Rind in 2004.

...

Since [the late 17th century], there seems to have been on average a slow increase in solar activity. Unless we find a way to reduce the amount of greenhouse gases we put into the atmosphere, such as carbon dioxide from fossil fuel burning, the solar influence is not expected to dominate climate change. But the solar variations are expected to continue to modulate both warming and cooling trends at the level of 0.1 to 0.2 degrees Celsius (0.18 to 0.26 Fahrenheit) over many years.

Yet less than 1%* of the earth's population refuse to believe it.






* 1% is obviously just a number thrown out there but you get the point

Only 25 percent is from the cyclical solar fluctuations and these greenhouse models have been under predicting the trend and yet you think its not an important concern :huh:

Its not exactly a brilliant idea to do nothing until we push past limit and hit a runaway feedback mechanism in our climate. Risk adverse greener technology in the best strategy as there are long term benefits to more efficient living regardless.

believe...... what? that the sun is responsible for 25% of the Earth's warming and that man is responsible for the other 75%? and since there's nothing we can do about the sun, we should focus on and try to reverse the 75% that we're causing? glad to hear you're such an environmentalist.

although we could always just get one of these, except for the whole Earth:

nothing remotely reliable about an industry-funded "report."

every "report" that says AGW is actually just "the sun's fault" is missing the point. the fact that some "report" uses science-ish-ness to befuddle those who haven't any scientific knowledge -- that makes it LESS reliable, not more.

it takes a real moron to think that we can puke volatile, reactive chemicals into the air and have no reactions resulting from that. a REAL moron.

or a paid shill, sitting pretty on an industry-funded chair in an industry-funded office.

I'm always confused at how people get this idea in their heads that being a pretty skilled MTB rider means they're brilliant political analysts as well. try to remember that when money is at stake, corruption will lead the pack, and honesty will be left sitting on the porch.

ha!

Of course the chemicals and pollutants that we are putting in the air are my no means helping and we as a species definitely need to cut back and use resources such as electric, solar, geo thermal, etc. I just thought that it was a bit interesting that the sun plays a big part in the global warming factor and not what Al Gore has been incorrectly preaching.

Read into it as you will, just thought that it would make an interesting, friendly debate here. Keep it coming.
