First- Your thread title is misleading and is getting tiresome in its repetition.
As a specific instance, I will readily agree that death threats are ridiculous and they should be tracked down and the threateners should be dealt with appropriately.
With that said, there are large numbers of people that agree with the "science" but disagree with the subjective impact of the "science" and further strenuously disagree with the measures contemplated to deal with the already heavily subjective impact of the "science". That is not, even remotely, science denying. And, frankly, you know it.
There does exist a lunatic fringe that doesnt believe the basic science behind climate change. By basic science, I mean that man does release ghg into the atmosphere and that in a controlled environment ghgs trap heat. That is ALL that has been generally accepted as science. The actual impact on the climate is heavily subjective and the impact to the measures contemplated to combat it are even more heavily subjective. This is undeniable.
Australia is experiencing tough economic times just like a lot of the world. They are proposing a lot of carbon based taxes and anti-pollution measures. Analysts are projecting $50/month higher electric bills and the loss of 10,000 coal jobs and 45,000 manufacturing jobs if implemented. 10% higher grocery bills, 15% increase in gas costs.
Now do I think there is exageration in those numbers, of course. But that is the framework we are dealing in. The politicians that favor the taxes use the local scientists as their front and hide behind their findings. This has created a situation where the scientists are cast as the bad guys. As a result, people misguidingly lash out at them.
If a carbon tax means a working coal miner loses his job and can not feed his family and the politicians justify the taxes based on the scientists staements, it is not unlikely that some people will lash out at them. As I said earlier, they should not do it, but it certainly doesnt mean it is happening because the are "scisnce" deniers. That is just lazy sensationalism and, quite frankly, hinders the progress of the cause you wish to push.
