Reducing to 350
The magic number has been found and it is not 42: it’s 350. That’s the concentration in ppm (parts per million) of CO2 we need to keep at maximum in the atmosphere.
For all of human history, the concentration was around 275ppm. We’ve now raised it to 385 with burning of fossil fuels. So, we need to work at getting it down – to at least 350.

That sure makes more sense than newspaper articles writing about “that poisonous substance CO2.”
If David Suzuki can suggest to jail nonconformist, I suggest to jail environmentalists who cause the present backlash to those oldfashioned winters. 
Now if global warming, which was going so nicely in the nineties, would extend the treeline about 500 km into the Northern hemisphere, would that bring the CO2 concentration back down to 275 ppm again?
Climate change is a natural thing and I believe nature can handle human civilization.
