On June 20, a remote Siberian town called Verkhoyansk logged a temperature of 38° Celsius (100.4° Fahrenheit), likely setting a new high-temperature record for the Arctic Circle (SN: 6/23/20). But that new record didn’t occur in a vacuum: It’s part of a long-term trend of historically hot temperatures in Siberia linked to climate change, and […] More
The remote Siberian town of Verkhoyansk is known for its extreme cold: Winter temperatures often dip below –50° Celsius. But on June 20, temperatures in the town soared to a high of 38° C (100.4° Fahrenheit). If confirmed by the World Meteorological Association, that marks the hottest temperature ever recorded north of the Arctic Circle. […] More
Mangrove forests can only take so much. The famously resilient, salt-tolerant and twisty trees have so far managed to keep pace with rising sea levels, providing a valuable buffer to coastal communities against pounding storm surges. Now, researchers have found the forests’ limit. Mangroves cannot survive in seas rising faster than about 7 millimeters per […] More
Tree StoryValerie TrouetJohns Hopkins Univ., $27 Once you look at trees through the eyes of a dendrochronologist, you never quite see the leafy wonders the same way again. Peel away the hard, rough bark and there is a living document, history recorded in rings of wood cells. Each tree ring pattern of growth is unique, […] More
Increasingly powerful tropical cyclones in the North Pacific Ocean may be fueling a powerful north-flowing ocean current, helping to boost the amount of heat it ferries to northern latitudes. By enhancing the speed of some ocean whirlpools called eddies, and suppressing the spin of others, the passing storms may be accelerating the heat-carrying Kuroshio Current […] More
Stay-at-home orders haven’t just curbed the spread of COVID-19. They’ve briefly cleared the air. Daily global carbon dioxide emissions dropped 17 percent, from about 100 million metric tons to about 83 million metric tons, in early April compared with average daily emissions in 2019, researchers report May 19 in Nature Climate Change. Among other changes, […] More
Climate change is increasingly becoming part of everyday conversations. For those who want to join the discussions, there is no shortage of books that give detailed background and context on the subject. The question is, which to read? Science News staff members have reviewed several books published this year to guide you to which ones […] More
Three years ago, Kim Cobb was feeling “completely overwhelmed” by the problem of climate change. Cobb spends her days studying climate change as director of the Global Change Program at Georgia Tech in Atlanta, but she felt paralyzed over how to be part of the solution in her personal life. The barriers felt immense. She […] More
