Eric Rignot
Eric J. Rignot (* 1960 or 1961) is an American Earth system scientist . He is a professor at the University of California, Irvine .
Life
Rignot graduated from the École Centrale des Arts et Manufactures with an engineering degree in 1985 . This was followed by master’s degrees in astronomy from the University of Paris VI Pierre and Marie Curie (1986) and electrical engineering (1987) and aerospace engineering (1988) from the University of Southern California , where he also worked as a research assistant during this time. In 1991 he completed his doctoral degree in electrical engineering there. From 1988 he worked in various roles at the Jet Propulsion Laboratory . Since 2007 he has been Professor of Earth System Science at the University of California, Irvine .
In 2018 Rignot was elected to the National Academy of Sciences .
Act
Rignot works to understand the interactions between ice and climate , in particular to determine the reaction of the ice sheets in Antarctica and Greenland to global warming in the coming century and the consequent rise in global sea levels . In a study from 2014 he was able to show that the ice melt in the Amundsen Sea has passed a “point of no return” and will therefore progress inexorably (cf. tipping elements in the Earth system ). A study by Rignot and colleagues in 2019 attracted attention, in which it was possible to use satellite measurements to show that the rate of loss of the Antarctic ice has accelerated dramatically over the past four decades, while the snow supply has remained relatively constant; the melting of the ice was therefore faster than previously assumed and now also affected the previously relatively stable East Antarctica. The complete melting of the Antarctic ice sheet would raise the sea level by about 60 meters.
Rignot was involved in the Fourth Assessment Report of the IPCC .
The Rignot Glacier was named after him.
