A LESS EXTREME CLIMATE (MAYBE)
Scientists in Zurich and in California and in North Carolina have been working to understand what the future holds for us. You’ll be glad to hear it isn’t all bad.
That business about storms getting worse and worse?
It seems to be wrong. Scientists at ETH Zurich and the California Institute of Technology say their work shows the opposite. As things get hotter, they get more boring and less extreme. The future should have less in the way of crazy weather variations.
That’s good right?
But Dr. Anthony Parolari (Duke University) says sales of dehydrated water will be going up out west.
(That’s me, being witty. Don’t go looking for dehydrated water on Amazon. This is just my way of saying that water could get scarce in the western part of the US.)
Parolari says that he and his colleagues have re-run some of their models and have drilled down through some theoretical work and found a surprise. Rather than expecting things to get more and more extreme, they now expect the opposite. Things in the mid latitudes should be less variable and we don’t have to worry about so many fierce cold snaps.
They will come less often, not more often.
No one’s saying things won’t get hot. The warming trend is well established. But the expectation of increasing variation seems – for now, at least – to be off the table.
Here’s the thing. Predicting is part of how science works. If the predictions of a scientist turn out right, this supports the idea that he’s/she’s onto something; it is considered a form (more or less) of evidence. But these are just computer models. They’re only right if the assumptions that went into them are right and the model itself isn’t flawed. We don’t know that.
I wouldn’t move or stay based on a computer model.
Would it hurt to stock up on dehydrated water?
