Long, recent and well-supported with links to science and studies. Conclusion:
The truth is we are in extremely serious trouble as an entire species, and so is everything else on the planet. Almost nobody seems to understand how incredibly difficult survival will be under these temperatures or whether or not if it will be even possible.
For most species, the answer is “Not possible”. Extinction is already a certainty. For the remaining species, including humans, we will suffer terribly as we attempt to find enough food and water, events which are happening NOW in 2013 and will only worsen in the years ahead.
The reality is, we may very well not survive this at all. Most projections have proven to be hopelessly optimistic, with some truly catastrophic oversights, and even the ‘worst case scenarios’ being found to be far too optimistic.
Incidentally, with the caveat that one must consider the source (“Darwin Was Wrong!”) the New Scientist published a map back in 2009 of what the world might look like a mere 4 degrees centigrade warmer, a figure we are well on track to bust way past, as the linked article explains. Note that only the green areas are habitable. As for the magazine’s projection of vast solar arrays in the majority of the world that is uninhabitable, along with nuclear power, hydrothermal power and densely packed high-rise cities in the few livable regions left on the globe, I think we can safely say that such an idea is insane. Were the map’s outcome to occur, it is pretty much a dead certainty that what few humans who remained would be hunter gatherers again, or perhaps subsistence farmers. Also note that other studies contradict the “green” scenario for Siberia, suggesting instead that the whole melted region will be transformed into an uninhabitable peat bog giving off vast amounts of methane that is far more heat-trapping than carbon. Anyway, here is the map:
