Waiting on Katla

Isn't that a beautiful sunset?  The red is from all the volcanic ash in the atmosphere.  Anyway, New Scientist says that the Katla volcano, also in Iceland, is much larger than the currently erupting Eyjafjallajökull volcano.  Worse, the last three times Eyjafjallajökull has erupted, Katla has also erupted -- and Katla is overdue.

The USA Today worries that a Katla eruption could lead to global cooling while the Telegraph claims global warming causes volcanic eruptions by melting the Icelandic ice cap and releasing pressure on the magma underneath the crust of the Earth.

What seems clear is that current climate models ignore Volcanoes and Solar Cycle wild cards but both appear in the hand we've been dealt.
