We do have fossil records of periods showing times where Co2 was much higher than now, and that although the climate was different, it was perfectly viable for human life. we DO know for a fact that we could as a species handle significantly higher amounts of CO2 in the atmosphere, it's whether individual regions could that is the issue, a question that we simply don't know the answer to. Something that is not helped when the stats are being deliberately fiddled to show disasters in every scenario by the IPCC and co. Climate change will not, absolutely will not kill us as a species, but it could devastate entire economies, or it could not. I would rather not devastate our economy to avoid a situation that might devastate our economy. fuck scientific principles then? Welcome to the de-enlightenment. you forgot to say - think of the childreeeeen! Nothing wrong with trying to make more efficient technology. The problem is that the whole point of increasing efficiency is to drive costs down, do more, with less. This is not what we are getting. Inefficient, non-viable energy sources are being subsidised because they are "greener", this increases our energy cost. New technology's are being put on the market that are apparently "greener" but actually use more toxic materials. The reality is that our money is being taken away, our business is being destroyed, and so far not 1 gram of Co2 has been "saved. the whole problem with climate change propaganda, is that it is "causing" people to ignore real pollution problems that exist today, that ARE killing and maiming people in the hundreds of thousands every year. Real quantifiable problems, with current day solutions, are basically being sidelined.
