Faculty Spotlight

Professor John A. Higgins

Title: Associate Professor of Geosciences
Research Areas:

Professor John Higgins' primary research interest is the evolution of the carbon cycle and the global climate system over Earth history.  One focus has been on processes that control the chemical composition of seawater, and how those processes have changed on geologic timescales.  Another is how on the chemistry of carbonate sediments is affected by processes that occur post-deposition.  These include early diagenetic recrystallization, dolomitization and hydrothermal alteration.  The tools Prof. Higgins has employed to study these include numerical models of chemical and isotopic biogeochemical cycles, as well as analysis of traditional stable isotopes of oxygen and carbon, and new isotope systems such as magnesium, calcium, and potassium.

Earth last year wasn't quite as hot as 2016's record-shattering mark, but it ranked second or third, depending on who was counting. Which year is first, second or third doesn't really matter much, said Princeton University climate scientist Gabriel Vecchi. What really matters is the clear warming trend, he said.

Consider this cold comfort: A quick study of the brutal American cold snap found that the Arctic blast really wasn’t global warming but a freak of nature. “It was very definitely strange, especially now,” said study co-author Prof. Gabriel Vecchi of Princeton University.

The idea of mobile continents and continental drift was considered revolutionary before the 1960s. In this BBC radio show, science writer and broadcaster Roland Pease, highlights Geosciences' Prof. W. Jason Morgan *64 and mentor Prof. Harry Hess *32 as key players in the evolution of plate tectonics. Pease believes this type of scientific...
