CO2, atmospheric levels now exceed 400 parts per million (ppm).
Paleological records show that every time CO2 levels have exceeded 300
ppm there has been an ice age. Every time, without exception.
The same records show that there have been a series of ice ages over
the past 5 million years, naturally occurring every 100,000 years,
with about 90,000 years of glaciation followed by about 12,000 years
of interglacial climate.
The last ice age ended about 12,000 years ago. I am more inclined to
believe what has happened in the past without exception, than the
incredibly unreliable speculation about what will happen into the
future 100 to 1000 years from now. Are planet is cyclical, what goes
around comes around.
Does this mean we will be heading into an ice age anytime soon,
certainly not. One thing I do know for sure is that the sky is not
falling, Chicken Little.
