Following a trail of Googlecrumbs, I stumbled across this today, which may be the first climate story I ever wrote. It’s on Henri Grissino-Mayer’s tree ring work out at El Malpais, one of the best and longest southwest climate reconstructions available:
This may be a desert, but new research suggests the past two centuries have been the wettest period of the past 1,500 years in New Mexico.
And the past 20 years have been the wettest of all, with rainfall 23 percent above the long-term New Mexico average, according to a study by University of Arizona scientist Henri Grissino-Mayer of more than 2,000 years of tree rings.
The implication of this and other long-term climate data is that the farms, cities and irrigation networks of the modern Southwest were built on rivers swollen by unusually wet weather.
In retrospect, I realize that in one form or another I keep writing the same story over and over.
