Whilst I would agree with what you're saying but many 'experts' disagree. I shall now post their reasoning.HarveyH42 said:The world was a much warmer place before the Ice Age, campared to present day. Man had nothing to do with either. Don't think any of the crap these nut jobs are proposing will have the slightest impact on the rising temperature, it's natural and normal, it's going to happen. It would be better to work toward adapting to the change.
Only good thing is the part about conserving resources, and make more efficient use. But mostly not trashing are enviroment, and starting to clean up the mess. I spent half my life on the side of a mountain, still find large cities discusting. The Native Americans had the right idea, bummer the british came and destroyed most of them.
Well human emissions only account for <1% of the annual emmisions and whilst I do believe there will be some build up in the amptmosphere, I don't believe that all the CO2 we release stays in the ampmosphere, most of it is absorbed by plants. It's BS that the CO2 level is going up by 1% per year!Myth 1 - Ice core records show that changes in temperature drive changes in carbon dioxide, and it is not carbon dioxide that is driving the current warming
Levels of atmospheric CO2 are higher than at any time in the last 430,000 years

Only the first part of this statement is true. Over the several hundred thousand years covered by the ice core record, the temperature changes were primarily driven by changes in the Earth’s orbit around the sun. Over this period, changes in temperature did drive changes in carbon dioxide (CO2). Concentrations of CO2 are now much higher and increasing much faster than at any time in at least the last 600,000 years. This should be a warning that what is happening now is very different to what happened in the past.
In fact, over the last 100 years CO2 concentrations have increased by 30% due mainly to human-induced emissions from fossil fuels. Because CO2 is a greenhouse gas, the increased concentrations have contributed to the recent warming and probably most of the warming over the last 50 years.
Myth 5 - Climate models are too complex and uncertain to provide useful projections of climate change
There have been major advances in the development and use of models over the last 20 years. The models are based mainly on the laws of physics. There are also empirical techniques which use, for example, studies of detailed processes involved in cloud formation. The most advanced computer models also include detailed coupling of the circulations of atmosphere and oceans, along with detailed descriptions of the feedbacks between all components of the climate system including the cryosphere and biosphere. Climate models have been used to reproduce the main features of the current climate, the temperature changes over the last hundred years and the main features of the Holocene (6,000 years ago) and Last Glacial Maximum (21,000) years ago.
The bottom line is that current models enable us to attribute the causes of past climate change and predict the main features of the future climate with a high degree of confidence. We now need to provide more regional detail and more complete analysis of extreme events.
A beautiful statistic. So now the temperatures are 270 degrees Kelvin whereas before they were...ummm...135?temp at that level has risen over 200%
That's true, but you're the first person I've known to suggest that the current trend towards alternative energy is somehow driven by the oil companies. I'm not saying you're wrong, but my impression is that that's taking the oil companies' conspiracies (and they do conspire) to one step beyond reality.The oil giants have been control and enjoyed huge profits for a very long time, don't image they plan on just stepping aside. The oil producing countries have way too much control over the profits, must be something in the works to turn things around.
HarveyH42 said:I'm still confused on how they became so focused on CO2 emissions being the primary contributing factor. Does the Sun's temperature remain constant?
Hero999 said:Nevertheless it still proves a point, also Canada's largest source of CO2 emissions is their natural coniferous forrest.

Where did I go wrong with my math?
HiTech said:The absolute best solution to global warming is to put Al Gore inside a block of ice, tethered to a an old diesel motor, and tossed overboard in the arctic ocean.
It isn't the melting of the ice caps that would cause the sea level to rise (try putting an ice cube in a glass of water full to the brim and it won't over flow), it's the ice on the land melting that will cause the sea level to rise.Souper man said:If you think about it, with 'gobal warming' melting the ice caps, water levels would rise globally about 20ft.
The gulf stream stopping will only cool Europe, north weast Africa and the Eastern states and I've heard it will make Centreal America drier. The rest of the world will continiue to warm perhaps even more so since the gulf stream isn't taking the heat away.Thats not that bad. also, the atlantic water conveyor belt, which is water in the oceans that flow from the gulf of mexico to britain, will stop, causing worldwide cooling. But I think that perhaps global warming and worldwide cooling may cancel eachother out. I also think that there already fluctuations in earths temperature, we may not notice it for a long time.
