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
