In Greenland, Exactly Where Meltwater Enters the Ocean Matters

In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.

Meet Pepperoni the Robin, and Friends

Natalie Boelman and colleagues are tagging American robins near Slave Lake, Alberta, Canada, as the birds migrate north to nesting grounds. In a recent blog post for NASA, she put up videos about their work. You can watch some of them below, or go to the blog page at NASA’s Earth Observatory to see and read more.

Weber, Plank Elected to American Academy of Arts and Science

Elke Weber, who studies how people make decisions and how they think about climate change, and Terry Plank, who probes deep into the Earth’s interior to study magma and how volcanoes erupt, are among the members elected to the American Academy of Arts and Science this year.

Walter Pitman and the Smoking Gun of Plate Tectonics

“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing of the separation of the continents.”

Accounting for Volcanoes Using Tools of Economics

Climate scientists teamed up with an econometrics expert to develop an innovative new method for picking out past volcanic eruptions in temperature reconstructions going back millennia and gauging their impact on the climate.

Migration Mysteries of the American Robin

Ecologist Natalie Boelman is headed back to the far north to study birds—this time to the town of Slave Lake, in northern Alberta, Canada, to track the migration of American robins. She will have some schoolchildren in New York remotely helping her as she and her colleagues get to work.
