Jerry Mitrovica and geological influences on sea level rise

Jerry Mitrovica from Harvard University sits at the surprisingly wobbly interface between the solid Earth, oceans and ice. Trained in serious geophysics, Jerry quickly found a niche in explaining how movements of the Earth’s mantle – in three dimensions – control the apparent variation of past sea levels. In many cases, this means pointing out that many or all of our records of past sea level are fundamentally altered by processes like dynamic topography and isostatic rebound. Continue reading →

Valérie Masson-Delmotte and the jigsaw puzzle of climate science

For Valérie Masson-Delmotte, climate science is like a jigsaw puzzle. Unlike a house of cards, where the removal of one element causes the whole thing to crash down, the central picture of a puzzle is still apparent when pieces — maybe even many pieces — are missing. Continue reading →

Lauren Andrews on glacial hydrology and field work in Greenland

Lauren Andrews has done some of the most interesting work I’ve seen on subglacial hydrology — as a grad student, and with a degree of independence that would be unusual in most any PhD.

Lauren grew up in a scientific/agricultural household: her father was a groundwater hydrologist but the family also ran a small farm, with a range of animals. Lauren was active in 4-H, an organization that promotes (among other things) individual responsibility and organization, skills that came into play during Lauren’s time on the Greenland Ice Sheet.

Robin Bell and the physics of glaciology

Running a small business

Robin Bell and her colleagues found a volcano under the Antarctic Ice Sheet and water freezing onto the bottom of kms-thick ice. She championed the idea that glaciology needed instrumentation capable of observing the full ice sheet — from surface to base — all at the same time. To this end, she bolted ship-based gear on a small plane and … tried it out. And it worked! And continues to work, all in support of the massive question of trying to figure out how the ice sheets will behave in warming world, and what sea levels will be in the coming decades to centuries.

Martin Siegert on Antarctic glaciology

The highs and lows of Antarctic science

For my first interview, I met with Martin Siegert, who I’ve known for a few years from meetings and a visit to the University of Edinburgh. Martin is the co-director of the Grantham Institute, a well-known climate institute based at Imperial College London, with a goal to, at least in part, bring climate science into a broader societal discussion.
