Pioneer Coal Mine Blue Whale of Catoosa Centralia Underground Fire Roadside America Greenland Sea (81°N)
Enjoy: roadside oddities, diners, and horror movies
Hobbies: gardening, #scicomm ( @ZLabe), hiking, traveling to lighthouses
Graduate work: Arctic – midlatitude climate variability (sea-ice changes)
Recent work: using ANNs to detect patterns of climate variability/change
Now at GFDL I am thinking about: detection and attribution of extreme events

ART BY JILL PELTO
Landscape of Change uses data
about sea level rise, glacier volume
decline, increasing global
temperatures, and the increasing use
of fossil fuels. These data lines
compose a landscape shaped by
the changing climate, a world in
which we are now living.
