Inside the C.I.A., She Became a Spy for Planet Earth

January 5, 2021 By William J. Broad The New York Times
Linda Zall played a starring role in American science that led to decades of major advances. But she never described her breakthroughs on television, or had books written about her, or received high scientific honors. One database of scientific publications lists her contributions as consisting of just three papers, with a conspicuous gap running from 1980 to 2020. The reason is that Dr. Zall’s decades of service to science were done in the secretive warrens of the Central Intelligence Agency.

Greenland Ice Sheet on Course to Lose Ice at Fastest Rate in 12,000 Years, Study Finds

The Greenland ice sheet is on track to lose mass at about four times the fastest rate observed over the past 12,000 years. At its current trajectory, such melting would dump huge quantities of freshwater into the sea, raising global sea levels and disrupting ocean currents, scientists concluded in new research Wednesday.

Growing Underwater Heat Blob Speeds Demise of Arctic Sea Ice

August 25, 2020 By Paul Voosen Science Magazine
Arctic sea ice is itself an endangered species. Next month its extent will reach its annual minimum, which is poised to be among the lowest on record. The trend is clear: Summer ice covers half the area it did in the 1980s, and because it is thinner, its volume is down 75%. With the Arctic warming three times faster than the global average, most scientists grimly acknowledge the inevitability of ice-free summers, perhaps as soon as 2035. “It’s definitely a when, not an if,” says Alek Petty, a polar scientist at NASA’s Goddard Space Flight Center.
