Question: Why can't we have balanced research, studying both sides of the argument on Global Warming?

Answer: Because large scale government funding only comes about if there is an urgent crisis to be dealt with. If they open the debate to skeptical climate researchers, they would quickly establish that there is no case for catastrophic global warming, they would poke holes in the works by alarmists and they would kill the movement entirely.

By the time they did that, the funding would be gone. Which means they couldn't do that. In short, the closer we get to disproving the alarmist case for global warming, the less funding there is to study either side.

Thus, we can only exist in two states, one where there is no alarm about global warming (and no funding), the other where there is alarm (and funding for alarmists). We will never see a scenario where there is no alarm about global warming but there is tons of research examining both sides of the question.
