California is a climate change “canary in a coal mine” (the links with coal particularly apt). There are many other vulnerable regions around the world of course, but California is particularly important because it is an American canary, and (in general) Americans only care about American events.
The Californian canary is in trouble:
The End of California?
…Of course, there is nothing normal about the fourth year of the great drought: According to climate scientists, it may be the worst arid spell in 1,200 years. For all the fields that will go fallow, all the forests that will catch fire, all the wells that will come up dry, the lasting impact of this drought for the ages will be remembered, in the most exported term of California start-ups, as a disrupter.
“We are embarked upon an experiment that no one has ever tried,” said Gov. Jerry Brown in early April, in ordering the first mandatory statewide water rationing for cities.
…
The Golden State may recover, but it won’t be the same place. Looking to the future, there is also the grim prospect that this dry spell is only the start of a “megadrought,” made worse by climate change. California has only about one year of water supply left in its reservoirs. What if the endless days without rain become endless years?In the cities of a changed California, brown is the new green. A residential lawn anywhere south of, say, Sacramento, is already considered an indulgence. “If the only person walking on your lawn is the person mowing it,” said Felicia Marcus, chairwoman of the State Water Resources Control Board, then maybe it should be taken out. The state wants people to convert lawns to drought-tolerant landscaping, or fake grass.
Artificial lakes filled with Sierra snowmelt will become baked-mud valleys, surrounded by ugly bathtub rings. Some rivers will dry completely — at least until a normal rain year. A few days ago, there was a bare trickle from the Napa, near the town of St. Helena, flowing through some of the most valuable vineyards on the planet. The state’s massive plumbing system, one of the biggest in the world, needs adequate snow in order to serve farmers in the Central Valley and techies in Silicon Valley. This year, California set a record low Sierra snowpack in April — 5 percent of normal — following the driest winter since records have been kept.
Not that I wish any ill on Californians, but in the grand scheme of things it is probably good for our global chances of action to limit climate change that such a clear example of the damaging effects are playing out in the USA’s back yard.
