For some corals, going bright may be part of their fight against bleaching. Higher-than-normal ocean temperatures can cause some corals to bleach and lose the beneficial algae that dwell within their cells. Those algae help feed the corals and give them their color, so bleached corals can become bone white, and may struggle to survive […] 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
As many as 220 million people around the world may be at risk of drinking arsenic-contaminated groundwater, a new study finds. Combining climate, environmental and geologic data with machine learning, researchers made a global map, described in the May 22 Science, that predicts where groundwater arsenic concentrations are likeliest to exceed 10 micrograms per liter, […] 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
A decade ago, climate change projections pointed to a distant future, 50 or 100 years down the road. But with each storm and fire season seemingly more ferocious than the last, it’s clear we’re already facing the impacts of climate change: Sea levels are rising, and storms, wildfires and droughts are intensifying, fueled by warmer […] More
Hurricane Maria roared across Puerto Rico in late September 2017. The storm caused an estimated $90 billion in damage, demolished the power grid (SN: 2/15/20, p. 22) and left more than half of the island’s residents without safe drinking water. Dachiramarie Vila recalls the smell of gasoline from generators choking the air. “The smell was […] More
