We are headed towards the future of what "Snowpiercer" depicts if we dont tackle this.
I think we are heading towards a future rather similar to a SyFy called Incorporated.

The world will be much warmer than now even if we stopped all CO2 emissions this second. I think that series was rather close to what we are looking at.
For example the "safe and effective" consensus we saw recently, that turned out to be total junk-science. And we have not yet faced the terrible consequences of that junk-science: on a societal level (MSM, most govt agencies) we just act as if it did not happen.
I don't understand this example, what are you referring to? And what was the total junk-science?
