Researchers studying Lake Iseo in northern Italy found that centuries of deforestation, farming and grazing since Roman times tripled sediment flow into the lake, rapidly building and steepening the Oglio River delta. This oversteepened delta became prone to underwater collapse during earthquakes, and the study ties two medieval quakes (1117 and 1222 CE) to delta failures that triggered tsunami waves on the lake.
At an IMF event, Managing Director Kristalina Georgieva said AI is disrupting global labor markets like a slow-moving tsunami, warning that young people entering the workforce face the greatest risk as routine entry-level jobs disappear. Singapore President Tharman Shanmugaratnam, co-chair of the World Bank's Jobs Council, called on governments to make pandemic-era employment support measures a permanent structural policy tool rather than a temporary crisis response.
Scientists compared sonar seafloor mapping taken before and after the 2022 Hunga Tonga-Hunga Ha'apai eruption, revealing physical changes to the underwater volcano that help explain the tsunami it triggered. The eruption's tsunami behaved differently from typical earthquake-generated waves, prompting researchers to investigate its distinct origin.
Scientific instruments positioned far from the epicenter picked up early signals of a major tsunami as it formed, according to a report on nature.com. The detection relied on distant sensors capable of registering the disturbance well before its full force reached coastlines.
Labor force participation among Americans 65 and older has climbed to 19.2%, up from roughly 12% in 2000, and 42% of sitting CEOs are now 60 or older—an unusually high share, according to executive recruiter Cowen Partners. Companies like Boeing, Verizon and Cracker Barrel have repeatedly brought back older or previously retired executives rather than promoting younger leaders.
