Ice ages do come and go but that process is over 50 to 100,000 years cycles, and there is nothing we can do to avoid them.

Right now we are in between such cycles which may last for 10 of thousands more years.

All of which has NOTHING TO DO WITH THE CURRENT CRISIS.

On the other hand, it has been shown without doubt the effects of green house gasses to raise the ocean temperatures by a few degrees, which could change global weather patterns, making some parts of the world much dryer, warmer, colder and wetter.

CO2 takes a long long time to be captured out of the atmosphere, so if we where to completely stop today zero output of CO2, it would take thousands of years for the CO2 up there to be brought down to more natural levels.

At any rate, the whole,fear of freezing due to ice ages is so laughable it is not even worth considering.
