The funniest thing about the Global Warming supporters is that they do not make a big deal about some current issues related to warming trends. There has been an explosive growth in jellyfish in 7 of the major seas of the world. It is affecting the fishing stocks. This is certainly a more urgent threat, and nobody is talking about it. Is this related to warming trends? Maybe but it is the first time in recent times that this has happened.
Just so i am clear. I think there is cyclical heating and cooling trends on the planet, and man is not to blame for it.

The sea ice at Antarctica was 1.6 million square kilometers larger that 1970 this last year. And from the looks of things the sea ice in the north will be much bigger this year than 1998.

So as new ice is formed old ice slips into the sea. Weeeee is this not great that global warming is causing the sea ice to get bigger by the minute?

Yeah, I was speaking to Dr. Scotese about this "Little Ice Age" you're referring to, and a multitude of factors may have caused it, but volcanism is the primary source. The problem with that theory is that these eruptions would have to have been very frequent and would've had to have thrown untold amounts of particles in the atmosphere. There is another theory - a meteor impact - which, combined with volcanism may have further contributed to global cooling. On top of that, there is speculation that ocean currents may have reversed. One thing is certain: judging by geologic record, an ice age occurs every 20,000 years and if you refer to Dr. Scotese's website, we are on the path to global cooling and another ice age - relatively 8000-10000 years away.

exactly....with so many stimuli into our system, earth, no one can say which factors combine to produce climactic changes on small scales, like decades or even centuries. Only in terms of millennium can we start to make rough predictions.

There is some irony out there as the people at foreignpolicy.com emphasize:

6. Greenhouse Gas Comes from Solar Panels

Think switching to solar energy will make you green? Think again. Many of the newest solar panels are manufactured with a gas that is 17,000 times more potent than carbon dioxide in contributing to global warming.

Nitrogen trifluoride, or NF3, is used for cleaning microcircuits during the manufacture of a host of modern electronics, including flat-screen TVs, iPhones, computer chips—and thin-film solar panels, the latest (and cheapest) generation of solar photovoltaics. (Time named the panels one of the best inventions of 2008.) Because industry estimates suggested that only about 2 percent of NF3 ever made it into the atmosphere, the chemical has been marketed as a cleaner alternative to other higher-emitting options. For the past decade, the U.S. Environmental Protection Agency has actively encouraged its use. NF3 also wasn’t deemed dangerous enough to be covered by the Kyoto Protocol, making it an attractive substitute for companies and signatory countries eager to lower their emissions footprints.

It turns out that NF3 might not be so green after all. “NF3 has a potential greenhouse impact larger than … even that of the world’s largest coal-fired power plants,” according to a June 2008 study by researchers at the University of California, Irvine. Because NF3 isn’t covered by Kyoto, few attempts have been made to measure it in the atmosphere. But last October, scientists at the Scripps Institution of Oceanography reported that four times more NF3 is present in the atmosphere than industry estimates suggest, and its concentration is rising 11 percent a year.

Compared with the damage caused by CO2 emissions, NF3 remains a blip because far less of it is emitted. But Ray Weiss, who led the Scripps team, thinks that, unless regulations require more complete greenhouse gas measurements, more unpleasant surprises will be in store. With NF3, he says, “We’re finding considerably more in the atmosphere than was expected. This [gas] won’t be the only example of that.”

I bet Al Gore will cry when he realizes he's contributing to global warming. Heh!
