Tree rings tell tale of drought in Mongolia over the last 2,000 years
A new analysis is shedding light on drought in Mongolia, both past and future.
By studying the rings of semifossilized trees, researchers constructed a climate history for the semiarid Asian nation spanning the last 2,060 years — going 1,000 years further back than previous studies.
It was suspected that a harsh drought from about 2000 to 2010 that killed tens of thousands of livestock was unprecedented in the region’s history and primarily the result of human-caused climate change. But the tree ring data show that the dry spell, while rare in its severity, was not outside the realm of natural climate variability, researchers report online March 14 in Science Advances.
The recent dry spell was the severest in recorded history. But the rings showed that an even more severe drought took place around the year 800, long before anthropogenic climate change began.
We STILL have to fill in the unknown with SOMETHING. We just cant accept we cant know everything.
When will we grow up?
