• 26 most common misconceptions on climate change
  The planet's climate is complex, but an element is now clear: the world is warming, this is due to human activity increasing levels of greenhouse gases, and it will have consequences. But there are still big uncertainties. A round-up by the New Scientist.

Please stop making assertions without facts about climate change.

1) We have no scientific evidence to suggest that the temperature and climate changes we are experiencing are are out of historical norms. I will go a step further and say that current temperature and climate change is well within historical norms given the best science of our day.

2) We have no scientific evidence to indicate that we have man made global warming. Again the facts indicate that man made CO2 contributes a negligible fraction of the global warming gases. Water vapor accounts for over 95% of the green house gases. Arguments that man made contributions are tipping the system simply are not justifiable given the large variances we see in water vapor.

3) The only indicators suggesting a warming problem arises from models that are extremely contraversial in the scientific community. The models suffer from material short comings. Poor validation limit the confidence we can place in them.

It's a quite extraordinary statement, that there is no scientific evidence for anything and that the models suggesting a warming problem are "extremely controversial". In reality, there is an unprecedented level of agreement in the scientific community: the climate is warming, this is not just a cycle, it's man-made.
