"[Kenneth] Tapping reports no change in the sun's magnetic field so far this cycle and warns that if the sun remains quiet for another year or two, it may indicate a repeat of that period of drastic cooling of the Earth, bringing massive snowfall and severe weather to the Northern Hemisphere". IF That's a big if. Solar Cycle Progression Page Has Changed | NOAA / NWS Space Weather Prediction Center

quote: We are at a normal low point in the cycle, which varies around 11 years. This is like looking at low tide and saying: ya know if the water doesn't come back this could result in a low average water level.

- but I am at a loss regarding the connection between sunspot activity and the Sun's intensity. I'm not sure the scientists know either, they just have reams of data on the correlation. It may be something as simple as solar energy being tied up in the magnetic fields is not free to radiate away from the sun, or that it results in changes to the energy levels (radio wave interference also associated with sunspot activity) and thus the spectrum of what is radiated.
I have to learn how to use footnotes. I don't think we have a mechanism for that, so you have to use html tags - footnote(1) becomes footnote(1) Then at the bottom you can do:(1) - footnote text and it becomes(1) - footnote text Enjoy.

Another issue is that the weather in the Northern Hemisphere is kept artificially warm by the Gulf Stream, and that significant change or disruption of this system would cause colder weather -- without any regard to global temperature levels.
This looks like a couple of straw dogs harnessed together to obfuscate and avoid the real issue. IF global warming is occurring (consensus is yes) then should we do something about it, or should we find excuses to keep our heads in the sand? Are we ready to start conscious control of the climate/weather?

Welcome to the fray fgarb.
Another way to do that here is [thumb=300]http://www.ngdc.noaa.gov/stp/SOLAR/COSMIC_RAYS/image/cr_ssn.gif[/thumb] where the number 300 sets the displayed picture width and the tumbnail (automatically centered) is a link to the full size image (this is really good for large images, say over 500 pixels wide)
Am I correct in seeing the blue data as the cosmic rays that are also involved in the production of carbon-14 in the atmosphere?
Based on this evidence, I see no reason to link sunspots or cosmic rays in any way to the warming that has been observed recently. Which it would not be if the warming were due to man's interference in the heat balance of the atmosphere, yes?
But you're better off looking at the actual flux of solar energy reaching us on the earth if you're trying to understand how the sun could have influenced the current climate. So if you could show no real change in the sun energy production other than that due to sunspots\cosmic rays (or similar data) but a real change in the flux of energy reaching the surface of the earth versus captured in the atmosphere, then couldn't you make an argument that the change was not due to the sun cycles?

A much bigger issue is the change in the Earth's albedo caused by deforestation. I read an article that suggested this trend has been with us since the start of the agricultural revolution, 10K years ago ... We're just finishing it up.

i have noticed both the changes in plant life , animal life, and temperature of my area. ... state flowers are almost becoming extinct to the states they were of origin to. There was an interesting show on public radio the other night, from the DNA Files. This one was on global warming and the effect already observed on evolution of species: The Heat Is On: Evolution in Action It was talking about animals migrating to stay in their "zone" and of relatively rapid evolution of species to adapt to the new conditions. Changes that have already been observed. I've been thinking that one of the "benefits" of global warming would be the rather incontestable evidence of evolution that would result from such widespread change to all kinds of ecologies as species adapt to new conditions. We should see many new instances of speciation, possibly enough development of new features to put the "macroevolution" question to bed. Moving into a period of punctuated evolution from one of stasis?

Too bad about the bandwidth. Did you try to download the MP3? Its 30 megs and took 3 minutes on my connection (DSL), but wouldn't play on my media player
The link is on this page. Otherwise you will have to wait for the CDs.

Most modern terrestrial habitats are heavily fragmented, primarily by human impacts. In short, there is no habitat to track to, or no way to get where their "zone" will exist. What I was struck by was the amount of evolution that was already taking place to adapt the various plant and animal organisms to the changes in climate, from breeding time to blooming time outside normal boundaries. I think fragmentation is a concern - for fragmented organisms. I expect cockroaches to survive regardless. There will doubtless be extinction, but this is one of the elements that will enable evolution to demonstrate what happens after extinction events, periods that show the most change in the fossil record.
Ultimately, my prediction is that even in those organisms with exceptional dispersal abilities, a significant risk of extinction - vice evolution - is the mostly likely outcome. You're thinking food chain crashes and other domino effects yes? Again I don't doubt that extinction will occur -- just that it will be the only thing that occurs.

what I'm asking is: by adding the carbons to our atmosphere, is the water containable space shrinking, and if shrinking, could the less air volume to support water mean that global warming could cause the sky to become permanently covered? Check out partial pressures quote: In other words the concentration of one gas doesn't affect the concentration of other gases.

The important thing is to notice that the (partial) pressure of H2O does not depend on the (partial) pressure of CO2 or other gases, rather it is dependent on temperature and the (partial) pressure of H20.
