i would agree w/ u... this world is all about money and no coorporation really gives a shit, i would agree that global warming is a threat

screw you hippies were not gonna be around to see the world end and were more likely to kill each other before the worlds get too hot to live in, so in the mean time enjoy your big block chevys before there is no fuel left to run them on

not a threat, a boat load of media hype, look at the temperature records, wqarming  and cooling is a NATURAL trend that has ahppened for millions of years, and climate change has yet to be proven in response to global warming. and that "great" institution known as the UN has become less accurate with their figures the more studies they have done. Sound like progress huh?

According to a broad review of scientific data requested by Congress: Climate Change has been proven. Sorry about that, mate.

"For all but the most recent 150 years, the academy scientists relied on "proxy" evidence from tree rings, corals, glaciers and ice cores, cave deposits, ocean and lake sediments, boreholes and other sources. They also examined indirect records such as paintings of glaciers in the Alps.

Combining that information gave the panel "a high level of confidence that the last few decades of the 20th century were warmer than any comparable period in the last 400 years," the academy said.

Overall, the panel agreed that the warming in the last few decades of the 20th century was unprecedented over the last 1,000 years, though relatively warm conditions persisted around the year 1000, followed by a "Little Ice Age" from about 1500 to 1850.

The scientists said they had less confidence in the evidence of temperatures before 1600. But they considered it reliable enough to conclude there were sharp spikes in carbon dioxide and methane, the two major "greenhouse" gases blamed for trapping heat in the atmosphere, beginning in the 20th century, after remaining fairly level for 12,000 years."

Now, lets think about this for a minute. We have a few billion automobiles, power plants, etc. Each one is spewing pollutants into the atmosphere. On what is essentially a ginormous spherical space-ship. Can this be good? No.

So essentially after a while, we might as well pucker our lips around the arse-end of a ford, and breathe deeply.

Sorry for the long post, but this is one of my "hot-button" issues.

I sort of assumed it was a given until I read the novel State of Fear written by Michael Crichton.  While it was obviously a fictionalized story, it included significant real historical data to suggest the evidence is at best equivocal.  The focus being on which glaciers are melting while ignoring those increasing in size.

The counter suggestion being that the weather cycles are significantly longer than man has recorded them, ergo the world may have gone through similar weather extremes in the past.  So when you significantly lengthen the line of history, what we term "extreme" - becomes a tiny ripple in the time line.

It was an interesting read if for no other reason than to spark the debate in another direction.

That book was the spawnpoint of a very long debate (with myself) - which ended with that view.

My opinion is that nobody has any real idea - because the whole thing has become politicized. Scientists cannot publish real, objective data because they are all too aware of who's funding their salary. Environmental organisations are stuck with the policies of the 1970s. 'Industries' are a bit too concerned about profits.

precisely, the hype is created to fund scientists, who will only creat more hype to get mroe funding and support their data. and trust me, the world has been hotter than this, and ice core samples have shown that the level of CO2 was far higher a few thousand years ago than they are today and the erath wasn't that much warmer. ALL the facts toigtehr (i.e. reading all glacier samples, not just thinning ones, etc.) suggest that the earth is still very much in balance.

agrees

have a + 1 on me

If we did not have global warming we would have an ice age about now. So by that global warming is our friend.
But i might get out of hand soon. Then it becomes our enemy.

Evidence?



Mcminty.

It's too late to reverse any man-made increase to the natural warming process of the Earth. All current debate is in hype format.

One large volcano or asteriod impact= end of global warming.
Global warming is a natural event offset by other natural events.
Mars is a dead planet because of global warming and last I checked, no cars factories or Americans to screw it up.  A million years of unoffset warming will destroy a atmosphere, but one hundred years of fossil fuel usage will not.

you must be living in a dream world

Not on the web but in a Swedish Science magazine. But i think it was considered a very controversial idea and it was just one science team who had come to that conclusion. It had started when Chinese farmers started growing rice. Evidently the rice fields produces a lot of gases that causes global warming. But the article also stated that, now we are overdoing it a bit and are probably gonna end up in a world of sh*i where the survival of the fittest rule will apply.

We do have temperature and CO2 records from the last 400,000 years...

This shows that the inter-glacial period we are in is common but we have managed to extend it, also CO2 levels we currently have have not been seen in the last 400,000 years, we have pushed the CO2 levels straight up compared to this recent data.

We ain't going to destroy the environment, but we will make it different and how quickly that changes will be affected by us. All major extinctions always occur when there is rapid changes in the climate. True there have been many times in geological history where there have been vastly more CO2 in the atmosphere but every one of those periods include massive amounts of volcanic activity... the earth is currently rather quite in volcanic activity and yet we see a high and ever increasing CO2 levels... the ONLY explanation is us humans burning the last 250 million years of accumulated carbon into the atmosphere in the last 200.
