It is common knowledge in the climate change scientific community that governments around the world had better be planning for a one-meter rise in global sea levels by the end of this century.
What isn’t common is for a world-renowned scientist to warn that there could be a greater rise than that before 2100 – in addition to a catastrophic two to three-meter rise by 2200, and worsening increases thereafter.
NASA emeritus scientist Robert Bindschadler, who worked for 35 years as a glaciologist at NASA Goddard Space Flight Center, is sounding these warnings.
He led 18 field expeditions to Antarctica, and has participated in many other expeditions to glaciers and ice caps around the world. Although he recently retired, he maintains an active interest in the dynamics of glaciers and ice sheets, investigating how remote sensing can be used to improve our understanding of the role of ice in the earth’s climate.
He actively developed applications that measure ice velocity and elevation using both visible and radar imagery, monitor melt of and snowfall on ice sheets by microwave emissions, and detect changes in ice sheet volume by repeat space-borne radar altimetry (using satellites to measure ice sheet thickness).
