The Worst-Case Global Warming Scenario? Much Of Earth Uninhabitable In 100 Years

Blog Early Warning discusses a new study, from the Proceedings of the National Academy of Sciences, laying out the most severe of climate change possibilities. Using a figure called “wet bulb temperature,” it assigns 1 in 20 odds to a doomsday situation in which a combination of higher temperature and oppressive humidity could make the majority of Earth unfit for human life a century from now:

If you were outside for an extended period during the hottest days of the year, even in the shade with wet clothing, you would die.To give you a feeling for the likely uninhabitable regions…it includes most of the eastern US, much of inland Brazil and Latin America, tropical Africa, pretty much all of India, portions of northern China, and most of Australia.

    http://www.iceagenow.com – cooling is MORE of a threat

    • connie dobbs

      Apathy and ignorance is the biggest threat. Thanks for letting us know you're part of the problem.

      • Tlachance

        Have you reconsidered yet? For three winters now, extreme cold has been the huge threat with more and more COLD records being shattered.

  • emperorreagan

    I <3 doom and gloom.

  • justagirl

    the coming of the next ice age should even things out. we'll be juuuuust fine.

  • FergalR

    Utter bollocks. They predicted .3C warming/decade for the last 30 years, we got half that much and now they say it's worse than we thought. Anyone who believes a word these charlatans says is a moron.

    Worst case for whom?

      Cool site.

    But look at the upside… No more Republicans!

    Oh goody, another doom-and-gloom prediction that's supposed to happen in a time when no one who made (or heard) the original prediction will be alive to call shenanigans if things don't happen as predicted.

    This kind of b.s. “science” is little different from religious lunatics who predict the return of Christ “within the next generation. Or two…”

      What if he did? I bet everyone would just see it as another reason to get drunk and yell “Woooooo.”

    The earth will be fine in the long run. Its likely that the human population will decrease to levels that are sustainable to the earth at the time. However, the current population is not sustainable in the long run due to our ineficiency and waste of resources. Oddly enough, and no one seems to give it much attention, is that we already have the knowledge and technology to make the world a sustainable paradise for all.
    Clean energy is already here….(Solar, wind, wave) It is simply not utilized enough. Coal and oil still blacken the earth, industry stomps and tears like godzilla taking a walk. Oh yes, we WILL die off, but others will survive and the earth will heal…..
    Ah yes, the Utopian dream. Remember that one?
    ….or if you prefer, Armageddon….LOL

      Damn Pinkos, ruinin' everyone's day.

    Much of it is uninhabitable now, has anyone been to New Jersey? Smokestacks as far as the eye can see. I give Louisiana five years. Seriously, anyone that still lives there has a lot more guts than brains. Can't blame them, though, who would want to miss Mardi Gras?

    • jesse ris

      Really?? You're gonna rip on Louisiana right now? If you pushed through a huge natural disaster and rebuilt your life and community, it's unlikely that you would immediately move because of an oil spill. And to say that we have done all of this to not miss a holiday is insulting! We've got guts…yes, of course, but we also have a lot of heart, faith, hometown pride, and we're smart enough not to kick people when they're down…which is more than I can say for you. If you're gonna start making predictions, how bout stick with someplace you know something about….asshole. I'd like to give you five years.

        Temper! Temper! Get a grip, will ya? Louisiana is fine, I watch True Blood. Gambit is my eighth favorite X-Man. I am just sayin' that after Katrina I'da been gone.
