New Work from Our Greenland Science Superheroes

Meet science superhero Allison

The GRate project evolved from Snow on Ice. Both bring together different science disciplines and tools to uncover past drivers and changes in Arctic climate in the Holocene (~12,000 yrs). Data from Snow on Ice was used in an updated model of ice sheet change, focusing regional on SW Greenland. GRate will expand the modeling to look at change across the broader Greenland Ice Sheet.

Each of our scientists is a superhero with cool tools that enable the super powers they use to uncover new scientific insights. Together they focus on ‘system science bringing to life new findings about past climate, that when matched to the present help us build models of the future. Educators visit our set of NGSS aligned instructional materials that focus on a main theme of ‘How do we know about the past? and explores the use of ‘science proxies’. Each superhero scientist has a set of activities and supports that help you bring their science story to life in your classroom in an engaging and personal way!

This National Science Foundation funded project led by the University at Buffalo, brings together experts from different institutions and scientific disciplines to explore ice sheet stability through the linked systems of ocean, ice and atmospheric conditions. The project is taking  a new look at the Arctic climate, questioning whether current warming conditions could actually stabilize the Greenland Ice Sheet if the continual reductions in Arctic sea ice were to unexpectedly change the Arctic hydrologic cycle. Paleoclimate records have shown that in the past newly exposed ocean water caused previously cold and dry Arctic air masses to warm, bringing additional moisture to the region. Could this happen again with some of the precipitation falling as additional snow? Increased snowfall on Greenland,  combined with temperatures cool enough to allow the snow to last through the summer, would cause the ice sheet to grow and begin to stabilize. This hypothesis is driving the Snow on Ice project.

In April, strong offshore winds over the northwest coast of Alaska led to openings in the ice cover called polynyas. This animation shows the polynyas, or openings in the ice cover, that formed in the Chukchi Sea from April 12-30. Credit: A. Gautier, NSIDC

If you don't have a favorite geologist - check out some of our projects at and meet some of the scientists studying #Antarctica

This is a great (and brave) article in Science.

It ends with a perfect example of how institutions can make (even quite small!) policy changes that have a real impact on diversity and inclusion.

Thank you, @GLopez_924!
