Science does not work by silencing contradictory theories or suppressing individuals who disagree with a proposed theory. Real science works by proposing a theory and then allowing and encouraging scientific scrutiny and testing.
- Climate change is an established fact. No one argues that. The data proves it
- The data also proves that climate change has always been the norm. In fact, the data shows that change in the environment is the norm. The Earth's climate has never been static.
- Global warming is a theory. No one has proved conclusively that the earth is warming all over the globe. For example, studies show that arctic is is melting away but also shows that antarctic ice is growing thus...any warming isn't really "global".
- Catastrophes from global warming are also theories because no one really knows what will happen if the entire planet were to go up in temperature. Which is also assuming that the entire earth is going up in temperature.
- Anthropogenic Global Warming (global warming caused by human activity) is even more theoretical because science hasn't proven a causal relationship between global warming (which is still unproven in the first place) and human activity.
All of it still theory. Much like the Theory of Evolution, since no one can really prove that human evolution took place, even the scientists who are the most ardent supporters of the concept still refer to it as a "Theory". It may be the most prevalent theory...almost every scientist thinks its probably what happens.....but....it remains a theory.

Apparently the debate is not over and the consensus is not reached. This article shows that the scientific community can't come up with concrete models and politicians and activists can only threaten what "might" happen in worst case scenarios.

By the way, notice this infamous trick of these supposed "experts". One of the reports cited as very authoratative is from the Arctic Monitoring and Assessment Program which is an "an expert group formed by eight Arctic governments". Experts on what? If you check their website http://www.amap.no/ you will see that they are NOT scientists. They are government environmental agencies and the permanent membership is political activist groups. This organization is cited as an authority but their only authority is in politics...NOT in environmental sciences of any type.
