Discovery of the new link between clouds and the biosphere grew out of efforts to explain increased cloud cover observed over an area of the Southern Ocean where a large bloom of phytoplankton was occurring. Based on satellite data, the researchers hypothesized that airborne particles produced by oxidation of the chemical isoprene which is emitted by the phytoplankton may have contributed to a doubling of cloud droplet concentrations seen over a large area of ocean off the eastern coast of South America.

I find it strange how most of you believe "astro-environmental" causes are more likely than things actually happening right here on our planet. Local causation just seems much more likely. You have the Hadley cells, air currents, the global ocean currents system, thermal convection, the carbon feedback cycle, etc. Phytoplankton are even making clouds...

In an effort to deny the reality of our affect on the planet, we shift our attention to so-called phenomena in space, which we have absolutely no control over. That seems like a nice coincidence, doesn't it? It takes the blame off us, and allows us to spend and consume without moral recourse for the costs we are incurring on the planet. We can now truly live in excess without care for cause.

Actually, the astro-environmental cause is the most influential impact on climate. How anyone could think otherwise leads me to believe there has been an awful lot of cool-aid drinking going on out there.
The sun is not stable as far as its emissions and its solar winds influence climate on this and every other planet in the solar system.
Therefore, a changing climate has been and always will be. In fact, as far as climate is concerned, the only constant is that it will change. If you want a static climate, you are on the wrong hunk of rock. Carbon taxes, horse-drawn carriages, a statue to Algore and the Church of Global Warming; nothing this puny human race can do to stop it.

Great thread soficrow! S & F!
Has Al Gore been notified? I wonder how long it will take him to come up with a theory to counter this claim?

Thanks MamaJ - great links too. ...It will take me a while to go through them though. ...Our world does change a lot doesn't it? Trying to get a handle on it is like raising a kid - just when you figure out what's happening, they're into another phase or stage. And you're miles behind again.
Oh yeah - I think this thread is still relevant. Lots of good questions, directions.
Thanks for commenting,

This is a bit off the wall, but our discussion here sparked a niggling memory and after some effort I tracked down the title. I suspect the work is at least somewhat relevant even though I've never seen or read it. Author Zindel is a science teacher: The Effect of Gamma Rays on Man-in-the-Moon Marigolds.
btw - I certainly know we exist in a much larger context than our own little planet and solar system, but take great exception to the argument that because we are so "small" and the universe is so "big" that nothing we do matters or can have any impact. I have no doubt that human activities impact life and our planet in diverse and mysterious ways - many destructive.
