Fw: Uma pergunta popperiana (2)

No seguimento de Fw: Uma pergunta popperiana, e via UK Libertarian, um post que vale a pena ler na íntegra: Happy Christmas (Global Warming is over):

.. one need not be a global warming scientist to see the problem here for environmental zealots. One need only apply some basic logic.

The first problem is that the theory is totally unfalsifiable. If warming proves warming and cooling proves warming, then warming does not actually mean anything. Any weather phenomenon can be used to show that the AGW theory is valid. When winter is cold and snowy: global warming. When winter is warm and rainy: global warming. When weather events seem to confirm the AGW theory, these weather events are trotted out as evidence in arguments claiming that AGW is a huge problem. When weather events seem to show the opposite, two arguments are typically made by proponents of the theory ..

Another problem is that the AGW theory is untestable because global warming is impossible to control for. If man-made CO2 is in fact responsible for the claimed warming of the atmosphere, how could you ever know it? How can you control for the entire planet earth? How can you ever know what conditions would be if things were another way? ..

.. Given this problem, what AGW scientists do is create computer models to make their “observations” .. the models completely failed to predict the cold and snows of recent winters .. As we saw with the climategate scandal, many of these so-called “scientists” are not above messing with their computer code to get the results they want.

These are far from the only problems with the AGW theory. There are many more. There are serious issues with the methods of observing, collecting, storing and interpreting temperature data ..
