The Pacific Doughboy and the Core

Here at the Trunkmonkey Research Institute we’ve been possessed of late by the Doughboys. This representation is not really very good. It is a plate carree projection extruded as a box. Trouble is, when you bend it round like our … Continue reading

Doughboys

I have seen the following attributed to Ritsema and van Heist but have not found it in any of their papers. People with no sense of verbal aesthetics have named the red things LLSVP’s for Large Low Shear Velocity Provinces. Sometimes they … Continue reading

Huston, We have a Few More Problems

Humans are not naturally inclined to science. We yearn for certainty, the sort of certainty mathematical equations could provide if only we could be certain of the factors. We cannot. We don’t really yearn for mathematics, it is just another … Continue reading

Large Igneous Provinces, Temperature, Sea Level, and Extinctions

We had been looking at the stuff one can easily google regarding global temperature and large igneous provinces (LIP’s) and it seemed there might be something, so we dug in. There is an organization, largeigneousprovinces.org, that has excel data in … Continue reading

Paving It Won’t Save It (The Planet, That is)

The oceans are the energy bank for the planet. They receive energy to great depth from the sun. Continents cool the planet. Daedalus suggested in jest that if we increased the area of the continents 5%, we could reverse the … Continue reading
