One point to note here:
…while global warming predictions abound — here’s2009 footage of former Vice President Al Gore predicting, based on computer models, that the entire northern polar ice caps would very likely be ice free in 5-7 years (spoiler: nope, of course) — most climate change activists are into longer-term predictions. Just yesterday the Natural Resources Defense Council published this interactive mapthat claimed to show “what kind of sea-level rise we’re in for under different emissions scenarios.” And in the notes section it gives a pretty staggering disparity for when we might reach those predicted levels. One article said it could be 200 years or so and another said 2,000 years. Two millennia.
