i still believe we need to be worrying about a ice age before global warming.
Oddly enough, global warming causing a massive melt off of polar ice could stop various ocean currents leading to an ice age in the upper latitudes. A current like the gulf stream is water density driven, cycling heat from the lower latitudes up to the poles. Which also means global warming could turn presently productive farm lands into deserts and have all kinds of unpredictable effects on climate.
Its one thing to have a belief and quite another to be playing Russian Roulette with the climate. We simply don't know
what non reversible tipping points could be reached. What we are seeing now is unprecedented in the last million years. We know we can prosper with the present climate, we don't know if we can prosper with a future man made roll of the dice.
Hey, buddy, that was a movie, not science.
Leave science to the scientists, okay? The irony here is that this cooling fluctuation in the long-term warming trend was predicted by top climate scientists some time ago, but politically-driven junk science alarmists like yourself labeled them as "deniers." :roll:
Who, like you?

Nobody said "IS the cause", Einstein. They've said "could cause".
Sorry, but I don't buy it. Climate will change and man will have little long-term effect on climate. Could, should, maybe, all would turn into an "I told you so" by the global warmers if in fact an ice age did happen to start.
Quite honestly, I want global warming. Another 1-2 degrees F would be ideal IMO.

Heh the month of Feb is about -6f colder in MN than avg. This winter has been brutal.

In at least one instance (the Late Ordovician Ice Age), CO2 levels were up to 15X higher than they are today -- some 4500 ppm. And yet the planet was locked in one of the worst ice ages it's ever seen.
..
The majority of such ice is indeed in the Antarctic and Greenland ice sheets. Unlocking all the water in those sheets would have a catastrophic effect on world sea levels.
However, sea-level is rising only 2-3mm/year (~25cm/century), the same rate its been rising for thousands of years, ever since we exited the last Ice Age. Southern Hemisphere ice appears to be growing at present, and Greenland ice shrinking very slowly.
...
It all depends on scale. From 1998, the trend is downward...but from 1900 onward, there's still a very slight upward trend. But if one looks back further still (say from 500 AD onward), the trend is cooling again. The earth is cooler now than it was then.
Look back a few more thousand years to the last Ice Age, and the earth is on a warming trend. Look all the way back to the Devonian, and we're cooling again.
So which of these is the "right" period to examine? Depends on what you're trying to prove of course.
...
I've always maintained that global warming is occurring, just that the anthropogenic (human-induced) portion is significantly smaller than claimed, and that the data doesn't indicate any reason to be alarmed (i.e. that the anticipated degree of warming is likely to be only a moderate annoyance in most regions, and even a minor benefit to some).

Man's contribution to climate change is a pittance compared to natural processes. If you want to concentrate on worthy causes, then help reduce pollution for the purpose of improving air quality and groundwater quality.

Something to keep in mind is that it doesn't matter whether it's global warming or global cooling, because either one of them will be put to the following political use:
1. The world's temperature is changing.
2. It's America's fault.

Tsk, tsk. Did anybody check out the data sets the original poster was using? Its quite hilarious when you realize how manipulative the blogger is doing with this data. For example, the GISS data shows a drop of ".75" degrees Celsius. But is that the truth?
On the data set for the GISS, the 2007 value is 87, while the 2008 value is .12... subtract those and you get .75. But apparently this moron blogger doesn't even understand what the data represents, the value is temperature CHANGE. A value of 12 versus a value of 87 both mean the temperature INCREASED in January of 2007 and 2008, just that the increase wasn't as large in 2008. So when he says the temperature "drops" he is completely incorrect, the temperature INCREASED, just at a slower rate than the previous year. As already pointed out by others, one doesn't make a trend based off of a single year, or a single data point.
In addition, its temperature changes in January... we all know that January is not representative of the entire year, rather, obviously, the entire year is representative. Essentially his argument is that "January 2008 is different than January 2007," whoopie. :roll: How about we wait for the entire year of 2008 to play out, instead of comparing a month here and a month there.
And if the blogger like the GISS so much, why doesn't he post their most recent press release?
"Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2007 tied with 1998 for Earth's second warmest year in a century."

Ooops.
