Cave Study Links Climate Change To California Droughts

California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic, according to a new study by UC Davis doctoral student Jessica Oster and geology professor Isabel Montañez. The finding, which comes from analyzing stalagmites from Moaning Cavern in the central Sierra Nevada, was published online Nov. 5 in the journal Earth and Planetary Science Letters. The sometimes spectacular mineral formations in caves such as Moaning Cavern and Black Chasm build up over centuries as water drips from the cave roof. Those drops of water pick up trace chemicals in their path through air, soil and rocks, and deposit the chemicals in the stalagmite... At the end of the last ice age about 15,000 years ago, climate records from Greenland show a warm period called the Bolling-Allerod period. Oster and Montanez's results show that at the same time, California became much drier. Episodes of relative cooling in the Arctic records, including the Younger Dryas period 13,000 years ago, were accompanied by wetter periods in California.

Tsk, tsk. This is a politically incorrect post. It doesn’t fit in Al Gore’s world, for sure. Global warming before SUVs. How could you?

After Obama declares a climate emergency, people like you will be locked up for your own good.

Same is true of the Sahara.

But do you really want a two-mile thick ice sheet over half of North America and Europe to get a few more inches of rain elsewhere?

Or maybe, as some theorize, it is the greater precip in Winter, for whatever reason, that results in ice sheets thick enough to linger through summer?

Hey, as long as I get three square a day and the thermostat is in *my* cell...

Imagine, someone believing that so much snow can fall that it doesn’t melt all summer, due to cooling — despite the fact that without heat, the snow couldn’t condense and freeze in the first place.

Droughts related to climate changes? Wow, who knew?
