The long view
Glaciers May Be Melting Faster Than We Expected
From Alaska to Antarctica, thousands of glaciers flow over the land and out to the ocean. These tidewater glaciers are rapidly retreating and melting, like much of Earth’s ice, continually adding to rising sea levels. But to date, scientists have struggled to pinpoint where on the face of a glacier’s terminus the most intense melting occurs—and exactly how fast it is happening. Until now.
Upholding Scientific Integrity at Federal Agencies
Republicans and Democrats on a House subcommittee on Thursday agreed that science-related policy decisions should be based on facts, but differed on how to protect the federal scientists who gather and analyze those facts from undue influence.
Hackers’ Latest Target: School Districts
Some hackers demand ransom; others sweep up personal data for sale to identity thieves. But whatever hackers’ motives, school systems around the country have been the targets of their cyberattacks. Nearly two-thirds of school districts in the United States serve fewer than 2,500 students, and many do not have a staff member dedicated solely to cybersecurity.
U.S. and Australia Team Up against China's Dominance in Rare Earths
An Australian rare-earth producer has enlisted an American partner to help it chip away at China’s dominance in supplying minerals that are crucial to making smartphones, missiles, batteries for electric vehicles and a long list of high-tech products. China has used its rare-earth dominance as a weapon in previous trade disputes and has signaled that it could do so again in its current fight with the U.S.
Coping with Climate Change with Forecast-Based Aid
Traditionally, disaster victims have received assistance after trouble hits. If a region is flooded, say, people in the area may get aid to rebuild. But a new approach to humanitarian giving is flipping the script and offering help in advance of disaster, using in-depth weather forecasting and risk analysis to predict future victims.
The World's Aging Dams Are Not Built for Ever More Extreme Weather
The town of Whaley Bridge in the UK has had to be evacuated after damage to a dam built in 1831. The Toddbrook Reservoir is just one of many ageing dams worldwide not designed for ever more extreme rainfall as the planet warms. Dams are typically designed to cope with a so-called 1-in-100-year flood event. But as the world warms the odds of extreme rainfall are changing, meaning the risk of failure is far greater. Engineers have been warning for years that many old dams around the world are already unsafe and need upgrading or dismantling.
