So all this snow has me thinking a lot about the possibility that we're looking not so much at global warming, but climate instability that'll toss us the other way, into a severe ice age (more). I've posted before about the consequences of rising sea levels, but the reality is that in the last half century, ocean levels have dropped significantly (more, more, more), and while many glaciers and ice systems have melted, others have expanded (lots more). While many suggest there's insufficient evidence so far, many climatologists believe that global warming can kickstart global cooling. With mile high glaciers, big enough to gouge out lake-sized holes from the earth, a significant percentage of human cities would be scraped away to nothing, leaving almost no archeological record (Australia may be a good place to escape to — Aboriginal culture was one of the only on the planet that survived — just barely — the most recent ice age). If one has to choose, warming is definitely better than the alternative…
The Mayan calender “ends” in 2012, which is when we go through Solar Cycle 24, a spike which may disrupt satellites, communication, and planes… but Solar Cycle 25, in 2022, is predicted by NASA to be “one of the weakest in centuries”, which may well be enough to tip the scales and again cover the planet in ice…
Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
