Its a natrual occurance from mother nature. If it was man made, why is it no one promoting global warming can explain the previous ice ages?

Its a proven fact our pollutants are disrupting the atmospheric conditions.

I strongly believe that regardless if there are other factors affecting global warming (besides human activity), out of respect and compassion for our own people, we can make wiser decisions to decrease our personal level of pollution:

* Commuting to work using a bike and public transportation.
* Refilling a bottle of drinking water.
* Minimizing waste by using plastic dishes instead of disposables.
* Asking for a paper bags at the grocery store, and reusing it as a recyclables container.
* Using the laundry for full loads instead just a few clothes
* Recycling plastic and paper, so that the size (and the amount) of the garbage bags can be dramatically reduced.

Pretty soon I'll start doing compost and planting strawberries and tomatoes... we'll see how it goes :-)

On any case, I've incorporated some those decisions into my life, and not only I feel that I've engaged in a healthier lifestyle, but when I'm ready to go to bed, i look back into my day, and I found this calm inner voice says that says: "well done".

Well stated Alan ~applause~

Do people really think the effects of the last ice age would last forever? For the average gobal temp add in the temps for the jurasic and placiden ages. This is not to say that we should not work to offset the return to normal temps.

Earth operates in 4 climate modes the first 3 are consecutive oceanic type and mode#3 is the most efficient at cooling with the result that the other 2 warm the earth faster anx have a hotter max optimal IF constrained by geometry.

The 4th mode causes catastrophic cooling but can only operate on a continental basis which means that the oceans absolutely must be separeted into basins & a captured oceanic hot pool to enable the mode to run for longer than 1 week.

We live in a time where mode#4 is possible and the results are a chain of glacial & interglacial periods.

We are just about to lose the gulf stream which is the only thing able to destabilise the mode#4 cells.

This warming is predicted in the last book of the old testment. We haven't seen anything yet. There is no stoping it., just be ready!

way to go, freak! you nuts have been waiting for the last judgement for 1900 years now, why don't you dress in a sheet and wait on a mountain?

what is the degree in ? applied gibberish?

We are at the end of an ice age cycle, it's happened before and will again.....

Geology.

Happen to have got my degree in 1987 before the narrowing down of the subject to suit the narrowed minds of the private fee paying boarding scholars,(they are a bit like arrows on a target board, very pointed, & somewhat bad for your health but no use at all for researching a wide subject).

For climate modes refer to NASA & its atmospheric physics section referring to planetary atmospheres. The important bit for the weathermen & global temperatures per planet is the fact that condensation & precipitation tends to occur in the ascending part of the (belt) cells. Even more interesting is the fact that higher enegy atmosphered tend to produce monsoonal flows linking hot pools in the ascending part of the (belt) cell with the descending part. Monsoonal flow is rather important on earth too.

Just for good measure when you have looked @ the pretty pictures in the atmospheric physics site, remember that the Earth as a result of being mixed continet & Ocean is able to operate in 4 climate modes. A pure continetal planet with thin atmosphere can only operate in modes #1 & #4. A purely oceanic planet with thin atmosphere can operate in modes #1,#2, & #3. The reson for mode#4 on Earth @ present is because the Central American land bridge has cut off equatorial connectivity allowing an oceanic hot pool to form.

Once any disruption to a proper long lived mode#4 loop cell (such as the gulf stream) is removed, the mode (#4) runs until the heat is drained out of the hot pool.

Mode#4 became possible once the land bridge cut off connectivity between the Pacific & Atlantic ~2.2Ma. The interval from then to now is called the "Pleistocene", aka. "Quaternary". This period is characterised by ice ages caused by the very efficient cooling caused by mode #4 which runs from the equatorial (El Nino) hot pool to the polar stratosphere, which is bloody cold. Tends to snow like hell over the laurentide region as a result forming a big ice cap.

Once the hot pool runs out of heat, the mode #4 loop cell shuts down & mode #1 takes over which allows the equatorial ocean to heat up. This will trigger more mode#4 pulses & more ice until a timespan when clear pack ice develops in the N.Atlantic & the thermohaline circulation switches back on & disrupts any future mode#4 cell within a week of its initiation.

The gulf stream last switched ON about 30,000Bp. The Earth has been warming back to ambient ever since that date as a simple result of interglacial oceanic modes #1 to #3. The time period after ice @ the Laurentide ice cap & the simultaneous loss of the (Interglacial start time) Fennoscandian ice cap out has been called the "Holocene" since at least the time of Huxley.

Mode #4 becomes stable again once the Gulf stream switches OFF as a result of ice out in the Boreal ocean.

All man made CO2 input does is increase the rate of surface warming & the rate of change.

Feeling like gibbering yet?

AL GORE and his private jets,big suv's,and all the mansions he owns. Thanks Al for destroying our planet. P.S. Al better raise our taxes again so you can cry some more!!!

good point.

ppl dont know anoything.. we need to get more worried about global ICE AGE... LOOng topic to discuss about wat we mite see iceage or global warming....

A combination of factors are involved.
Earth has not always had the same atmoshperic composition and in very distant earth history, carbon levels were extremely high. This benefited plants which in turn used the carbon and produced oxygen. The carbon sink - which we benefit from in the form of coal, oil, etc.- is one of the reasons we have an overall moderated climate today (in planetary terms). However, we have spent the last couple of hundred years releasing that trapped carbon by extensive or massive use of coal for hundreds of years and then the use of oil for the last 100 or so.
This is a simplified explanation. There are volcanoes, fires, and other naturally occuring phenomena that add to the carbon in the atmosphere. I cannot address the ocean or all of the systems involved on topix. It took years of study, argument, questioning, and argument for me to arrive at my opinions on the matter...opnions which I will not state on topix - people need to do their own work if they are sincere.
Lacking the human element, the carbon cycle does change condition naturally. However, for the first time in human history we are unlocking carbon sinks technologically and at the same time reducing the plant life that can help to "re-sink" it. One can only project where that might lead not taking into account any visible signs of possible effects.
I suggest extensive biological, paleontolical, physical geographical, glacial, geological, volcanological, astronomical, chemical, anthropological, dendroconlogical, etc. etc., studies before anyone makes up their mind or states a strong opinion. Science is a discipline not rhetorical grandstanding. It takes work, not turning on the radio to listen to or TV to watch the talking heads.
