> +/- a few million years I suppose.
>Let’s not forget, our existence as a species in this current form (however you want to measure it or date our creation), is a relative flash in the pan when measuring global climate changes. We’ve only been “thinking” for about 100K years. We started recording history for the future about 15K years ago (all arguable). By the time the next ice age starts to endanger our species, I would expect we have colonized other locations in our solar system and/or galaxy. Suffice it to say, I am not worried about global warming or global cooling for myself or the fruit of my loins for the next several generations. ;o)
The current warm era is called the Holocene and it started about 12-15,000 years ago. The over all cooling trend started 6,000 years ago. The previous intergalactic called the Eemian (which was much hotter than the current one) was about 130,000 years ago and lasted 15,000 years. Since we don’t know what causes ice ages or warm periods it’s hard to say exactly when the Holocene will end. However if it does end any time soon we better have a lot of underground cities and ton’s nuclear power plants to say warm when it does it us. We’re also no longer sure that ice ages happen slowly, the climate record seems to indicate rapid freezing is the norm.
“However if it does end any time soon we better have a lot of underground cities and ton’s nuclear power plants to say warm when it does it us. “
We should, using our industrial might, pump trillions of tons of co2 into the atmosphere to help forestall the ending of the Holocene.
