I agree completely. People seem to forget that the last ice age ended 10,000 years ago, yet it lasted for 1.6 million years. The Earth didn't in one day 10,000 years ago go from widespread glaciation to the temperate climate it has today; it was a very gradual change. The warming from this last ice age is still continuing now. The glaciers are not retreating because of human activity, they are retreating because they formed in cold places during the last ice age and these places are not meant to be cold. Any long term rise in temperature is entirely due to long-term climate cycles and ocean currents, orbital eccentricity (the Milankovitch cycles), and variations in solar output. As a final nail in the coffin of the junk science that is human activity-induced global warming, consider these three facts:
1. Sea level today is much lower than it was during the Cretaceous Period.
2. Average global temperature is much lower today than it was during the Cretaceous Period.
3. The ~1.5 degree rise in average global temperatures supposedly caused by human activity was completely negated for a few years by the eruption of Mt. Pinatubo in 1991. One small event completely offset 150 years of human industrial effects.
It is very arrogant and naive of us to think that we can affect the Earth so much in so little time. Thirty years ago everyone was claiming that global cooling was an impending doom. While the mindset of uneducated alarmists has changed greatly in the last thirty years, it is a safe bet the Earth itself has not.

Here is something to think about don't believe me check this stuff out...
1.Water(H2O) is the only element known to man to expand when it freezes every other element contracts when it freezes so that is the first fact. For example fill a milk jugg with water, now stick it in the freezer... come back later and it will have exploded from preassure of freezing water.
2.Icebergs are massive chunks of ice, only a few percent of the ice is above water, which means the rest of the ice is underwater.
3.The ice underwater because water expands when it freezes is displacing the liquid water. So when that iceberg melts all the ice under the water will contract and fill a smaller space, so the level of the water will be less now because the ice which was displacing the liquid water is unfrozen and now occupies a less amount of space.
4.Scientific models show that if all the ice on this planet melted we would see a 3" DROP in ocean levels NOT a rise but a DROP.
Now isn't that interesting.
Now for the greenhouse gasses.
1.Plants LOVE a carbon dioxide rich air supply.
2.The more carbon dioxide their is the faster they grow.
3.Plants use photosynthesis to get their food so they can grow.
4.When the plants sense a higher level of carbon dioxide they will make up for it by sucking up more and more and one of the products of photosynthesis is OXYGEN!!
5.So no matter how much CARBON DIOXIDE there is the plants will COMPENSATE and suck up more and grow faster and bigger. and the bigger the plant is the more OXYGEN it produces through photosynthesis

Your quite ignorant. I am 43 years old and started PHYSICALLY noticing the changing atmosphere around 1990 or so, I remember back in the 60's and early 70's going outside and NOT USING SUNBLOCK and getting a nice tan, now people get a hell of a nice BURN if they don't use sunblock, I live in wyoming and it used to SNOW here, back in the 80's when I moved here it would snow and snow and we had a hell of a cold, icy, snowy WINTER that lasted for 4 months, now we are lucky to get a couple good storms with snow, we are in a major drought, all the lakes in this area are drying up, they keep extending the boat ramps, I bet in 10 years or so most of these lakes in this area won't be suitable for boating as there won't be enough water. As soon as it rains here, it goes right into the soil. This planet IS heating up, look around you, use your eyes to see instead of your stubborn, idiotic "have to be right" bullchit way of thinking. People like you are the reason that not much will be done until it's too late.

Yes there was a period of cooling about 150,000 years ago but this cooling trend was brought about by different circumstances, global warming is not cooling lol. First off the increase of greenhouse gases (like methane -think of all the flatulence too ok!) and fossil fuel burning as well as deforestation all contribute.
So simply put this is how it works:
Deforestation=> less carbon cycling increasing amount of carbon in atmoshpere +6 Billion humans needing 2 gas guzzling cars each lol => x amount of Cars=>depleted fossil fuels=> Increased carbon dioxide, nirous oxides, sulphurs etc that get trapped in atmosphere and trap heat=> increased temperature globally=>melts ice caps and warms oceans=>warmer oceans alter ocean currents which drive climate patterns=>increased severe weather events (hurricane Katrina gained strength due to warm water temperature) and so on and so on....its a mess i think, a right bloody mess!
One important fact about the issue with global warming is how it affects humans and our current resource base none of which mattered during the cretaceous period =p

you suggest that we read books...well i have never read a book by al gore or by anyone funded by "companies getting paid to produce movies and books about earthly destruction due to global warming". i read science books and study biology. you should try it, you might find it interesting. as for what created the first ice age, there is still a debate, either a meteor, a large volcano, or a combination of both. there is evidence for this in the k-t barrier. check it out, you may learn something.

The US emits more, absolutely and per head, than any other country - although it also produces more wealth. When Kyoto was agreed, the US signed and committed to reducing its emissions by 6%. But since then it has pulled out of the agreement and its carbon dioxide emissions have increased to more than 15% above 1990 levels.
For the agreement to become a legally binding treaty, it had to be ratified by countries which together were responsible for at least 55% of the total 1990 emissions reported by the industrialised countries and emerging economies which made commitments to reduce their emissions under the protocol.
As the US accounted for 36.1% of those emissions, this 55% target was much harder to achieve without its participation.
But 141 countries banded together and the protocol came into force in February 2005.
President George W Bush said in March 2001 that the US would not ratify Kyoto because he thought it would damage the US economy and because it did not yet require developing countries to cut their emissions.
He says he backs improvements in energy efficiency through voluntary emissions reductions - rather than imposed targets - and through the development of cleaner technologies.
As a government scientist, James Hansen is taking a risk. He says there are things the White House doesn't want you to hear but he's going to say them anyway.
Hansen is arguably the world's leading researcher on global warming. He's the head of NASA's top institute studying the climate. But this imminent scientist tells correspondent Scott Pelley that the Bush administration is restricting who he can talk to and editing what he can say. Politicians, he says, are rewriting the science.
But he didn't hold back speaking to Pelley, telling 60 Minutes what he knows.
Asked if he believes the administration is censoring what he can say to the public, Hansen says: "Or they're censoring whether or not I can say it. I mean, I say what I believe if I'm allowed to say it."
What James Hansen believes is that global warming is accelerating. He points to the melting arctic and to Antarctica, where new data show massive losses of ice to the sea.
Is it fair to say at this point that humans control the climate? Is that possible?
"There's no doubt about that, says Hansen. "The natural changes, the speed of the natural changes is now dwarfed by the changes that humans are making to the atmosphere and to the surface."
Those human changes, he says, are driven by burning fossil fuels that pump out greenhouse gases like CO2, carbon dioxide. Hansen says his research shows that man has just 10 years to reduce greenhouse gases before global warming reaches what he calls a tipping point and becomes unstoppable. He says the White House is blocking that message.
"In my more than three decades in the government I've never witnessed such restrictions on the ability of scientists to communicate with the public," says Hansen.
Restrictions like this e-mail Hansen's institute received from NASA in 2004. "… there is a new review process … ," the e-mail read. "The White House (is) now reviewing all climate related press releases," it continued.
Why the scrutiny of Hansen's work? Well, his Goddard Institute for Space Studies is the source of respected but sobering research on warming. It recently announced 2005 was the warmest year on record. Hansen started at NASA more than 30 years ago, spending nearly all that time studying the earth. How important is his work? 60 Minutes asked someone at the top, Ralph Cicerone, president of the nation’s leading institute of science, the National Academy of Sciences.
"I can't think of anybody who I would say is better than Hansen. You might argue that there's two or three others as good, but nobody better," says Cicerone.
And Cicerone, who’s an atmospheric chemist, said the same thing every leading scientist told 60 Minutes.
"Climate change is really happening," says Cicerone.
Asked what is causing the changes, Cicernone says it's greenhouse gases: "Carbon dioxide and methane, and chlorofluorocarbons and a couple of others, which are all — the increases in their concentrations in the air are due to human activities. It's that simple."
But if it is that simple, why do some climate science reports look like they have been heavily edited at the White House? With science labeled "not sufficiently reliable." It’s a tone of scientific uncertainty the president set in his first months in office after he pulled out of a global treaty to reduce greenhouse gas emissions.
"We do not know how much our climate could, or will change in the future," President Bush said in 2001, speaking in the Rose Garden of the White House. "We do not know how fast change will occur, or even how some of our actions could impact it."

Weather is chaotic, just look at your local record highs and lows. The weather moves in cycles, we may be accelerating it slightly but it's going to change anyway. I would be more worried about pumping CFC's into the atmosphere eating ozone, that's why you get sunburn easier today than 20 years ago. There will be no earthly destruction from climate change, the climate has changed many times in the history of earth and stuff still lives, it's called evolution, the act of adapting to ones environment. Granted people may die, but thats the way it goes. We are over populated as it is. A little over 4.2 Billion by the way. Nature has a funny way of fixing itself.

This is not my specialty but I did a little research and found the following information, which seems to be in general agreement with the global warming hypothesis:
The very first ice age in the late Proterozoic period known as he "Snowball Earth" is thought to have been caused and ended by changes in CO2 levels in the atmosphere.
Atmospheric composition changes are thought to be the leading cause of climate changes. Other secondary causes include changes in the Earth's orbit known as the Milankovitch cycles, the relative location and amount of continental and oceanic crust, variations in solar output, the orbital dynamics of the Earth-Moon system, the impact of relatively large meteorites, and eruptions of supervolcanoes.

Global warming: myth or reality; I don't know. What I do know is that as technological advances continue, we pollute and destroy the environment more and more.
Thousands of years ago, there were not planes, trains, automobiles, space shuttles, and nuclear weapons. What if we haven't seen the worst yet because so many things present today are new to the last century?
