Mayewski: Climate can change in 1-2 years… and end Civilization

In a one-hour lecture delivered earlier this year, Professor Paul Mayewski of the Climate Change Institute explains how multiple methods of historical climate reconstruction reveal instances of abrupt climate change taking place over periods of just 1-2 years during human history. These changes are associated with roughly a quarter of a degree Celsius average temperature change, and yet have been associated with the destruction of entire civilizations. If you’d like to hear more about it, listen in here.

    More and more evidence is being discovered that we’ve gone way too far off the rails as a supposed sentient species and damaged our little fishbowl to the point that we may not be able to correct our actions or evade the consequences. i’ve sounded like a “kook” and a “crackpot” for years about our environment, but i had always hoped i was wrong and would just be an old fool. It’s looking ever more likely that we may be but a few generations from extinction EVEN IF we “change our ways”, which is unlikely at this point. All of us on the planet are effected by everything we each do – cutting down the rain forest in Brazil has consequences in China (and the rest of the world). The fact that our global population is still increasing is problematic, since we’re running out of many of the resources we need, causing extinction of species we rely on for food (like fish) and the way civilization “works” currently is so unbalanced that it’s unsustainable going forward.

  • On the environment, I don’t think you sound like a kook or crackpot. On issues like the need for revolution in the street, maybe leaning toward crackish.
