Cheering the Volcano

June 9, 2019

The eruption of Mt Pinatubo, in 1991, was a critical moment in climate science.

As the video above explains, James Hansen’s temperature projections included, as a test – a built-in assumption of a large volcanic eruption in the tropics in the early 90s.

Experts comment on the accuracy of Hansen’s projections, as proven out in his modeling of the global change following the eruption.

Short version: It happened, and it showed the models were correct.

Now, a new major eruption in Indonesia might be large enough to help test and refine the models yet again.

Below, my 2009 video explaining how well models like Hansen’s have worked.

Grim, but that’s where we are. Go Ash clouds!

    And yet the assholes still deny that what is happening is happening!

    I suppose some cooling is worth the increase in acidification rates.
