On the upside, all the catastrophies of the past provided the conditions that allowed you and I to be here today....I don't view that as all bad.

'Survival of the fittest' will prevail despite any of our efforts.

I heard an interesting report today about scientists overseas working on producing kerosene like fuel for aircraft from CO2. So far the production is very scant, by the liter not the barrel, but they say no pollutants are produced in the manufacture, and if solar and wind are used, energy needs are met without producing pollutants. And the CO2 is waste CO2.

Here is the problem, Plants need the CO2. They are going to muck things up by going overboard with that. It’s all hype and they need to stop the anti CO2 stuff while we are ahead. CO2 levels were higher during the last interglacial than they are now, it’s all BS.
