Curious about soil dampness over the centuries? The Guardian has a neat presentation here. Money quote:
But here’s the astounding part: Williams and his team also estimated what drought conditions would look like if human activities had not caused global warming … and they found that we would still likely be living through a once-in-a-century drought – but human activity accounts for about 46% of the severity of the current megadrought.
I tend to see the weather as a massive non-linear system ala Chaos Theory, so I’m not quite sure I can sit comfortably with that assertion. Still, the last few years in the graph was quite instructive, wasn’t it?
