From what I have seen on the news and from governmnets changes of half a degree celsius can destroy whole a habitats ( and if some people are to be believed in an apocalyptic way) corals inthe north sea are know almost completely gone etc. However about 12,000 years ago global temperature incresed by 10 degrees celsius in 20 years and temepratures in Greenland rose by 20 degrees in less than a decade. I don'e get how scientists know think such a small temperature increse can make such a huge diference when int he past larger changes got few results.

Well, now world kind has a population greater than a couple hundred thousand people. It is a lot easier to adapt to the changes when all that is around is a bunch of nomadic hunter-gatherers.
Global Warming is a fake - but not a fake at the same time.
The Earth is going through a "Cycle" it will be a hot time and then maybe another Ice Age will counter it, but I don't know if it will be a Ice Age, just a cold time.
Technically we are still in an Ice Age. An Ice Age is defined as a period in the Earths history when the poles are covered in ice. Most Ice ages have times of relative balminess. It is a very odd time we live in (by time I mean in ageographical sense of the last few tens of thousands of years) where we have ice capped poles as well as snowy winters throughout the world yet ice sheets have not come to dominate the world. Some scientists believe global warming will cause enough evaporation of water to block out the sun reflecting its heat and causing a major drop in temperatures. It is a shame that out of all the theories on global warming major governments seem to have leapt on the one that will get them the most money.

The only other waring period in the earths recoerded history was in the middle ages and it was on hundred times smaller than the warming we are experiencing at the moment. The fact that this has coincided with the widespread use of fossil fuels in human history is not merely a coincidence.
What is a coincidence is that NASA released reports saying that Mars's temperature is rising at the same rate of Earth. Yet within days of reporting this, the story was off the NASA website, and not reported by any major media outlet. Greenies out there hiding the truth again.
people really dont take into account natural forces. The mount st. helens eruption of 1982 released enough CO2 to make china look like a mouses breath. 200 years of emissions aint got nothing on st. helens.

But it isn't so much natural forces that are the problems. The world has evolved to just about balance. Yes occasionally volcanoes and the like chuck out vast amounts of CO2 and other greenhouse gases but other eco-systems like algae and trees etc counter it. What we are doing is upsetting the balance and producing too much CO2 for the world to handle. how much CO2 is their in the atmospere about 0.01% or something; because it is so small it doesn't take much extra to push it of balance.
Natural forces like volcanoes are rare (comparatively) and though powerful when they happen are realtively small. It is thngs like the long cycle that really affect things. Once CO2 is taken inby an animal to make a shell it may not see air again for thousands of years.
I used to believe in global Warming I don't anymore because well, global warming is a gradual increase and also decrease in Earth's temperature (like cycles) and we are just going through a cycle of warming up and eventually it will cool down again. I think last year was the coldest year on record. We have had 3 or 4 freezes(with Ice on trees and icicles in Florida and Florida rarely freezes) global Warming is just a ploy for people like Al Gore to make money off 'environmentalists'

Don't forget Yellowstone that over due for a good blowing up soon

It's been looking good to blow for a while now. Wasn't it a few years ago that one of the lakes disappeard because the ground underneath it bulged and displaced it.
Everyone knows that CFC's are bad. A single kg of the stuff can destroy 70,000 kg of atmospheric ozone.
Despite this the US uses CFC's to cool the gases etc. coming out the back of their stealth jets to make them more invisible.
(cool fact about stealth bombers. They are obviously almost invisible to radar. To see one you would need millions of transmitters all over the country beaming out signals. God bless mobile phones lol.)
Humans have contributed to things like the hole in the ozone layer, but we are not the sole cause of it. The polar ice caps on Mars are melting too. So? The Sun is in a higher energy cycle right now. Humans most likely caused, or at least contributed to, the non-temperature aspects of climate change and pollution, but the actual warming of the Earth is mostly due to the Sun itself, not us. Now, while it is not entirely us, it is happening at an unnatural pace. . .and the hole in the ozone layer is not natural. Period.
