  •  Of course we've been able to study climate change (0+ / 0-)

    There are a lot of different ways to study past climate change.  Ice cores, permafrost stuff.  Even looking at various mineral deposits, tree rings, etc.

    even with rapid increase in average temperatures the results are going to be unpredictable but that doesn't mean we can't adapt at need
    The problem we're facing is really one of numbers.  We have so many people and so much "efficiency" built into the system that there isn't a whole ton of room for error.  A major drought could kill off a huge chunk of the worlds population.  Or we could see malaria further north and south because of warming.  The acidification of the oceans is one I'm really worried about.
    •  I mean in an in depth, labotory style way (0+ / 0-)

      where in variables can be isolated and examined etc etc

      As I said the evidence we have from the little ice age along with looking at the sources you've named is useful but we still end up with multiple models saying many different things (though sometimes the differences are tiny).

      I do agree that out of the most immediate and known effects the changing acidication of the oceans presents in the short term the most danger both directly and indirectly imo. I'm less concerned about food though we may see some dramatic change in what foods grow where
