In the popular imagination, the Caribbean is paradise, an exotic place to escape to. But behind the images of balmy beaches and lush hotel grounds lies a crisis, the likes of which its residents have never experienced. Caribbean islands are in a water crisis, and their governments have warned that water scarcity may become the new norm. Within the past five years, every island in the region has experienced some sort of water scarcity. For example, Trinidad is experiencing its worst drought in recent memory, and residents are under water restrictions through at least the end of June 2024, with fines for anyone who violates the rules. Dominica, considered the nature island of the Caribbean for its mountain rain forests, is seeing a significant decrease in freshwater resources and increasingly frequent water shortages. In Grenada, known as the spice isle, drought has affected water systems throughout the island. Apartments in Havana, Cuba,...

Colorado has highly pathogenic avian influenza – also known as HPAI or bird flu – on a dairy farm, the ninth state with confirmed cases. The U.S. Department of Agriculture’s National Veterinary Services Laboratories confirmed the virus on April 25, 2024, in a herd in northeast Colorado. This farm is one of 35 dairy farms across the U.S. with verified cases of bird flu in cattle as of May 7, 2024, according to the USDA. Bird flu is not new to Colorado. The state experienced an outbreak in poultry that began in 2022. Since then, the USDA’s Animal and Plant Health Inspection Service has reported that 6.3 million birds in nine commercial flocks and 25 backyard flocks have been affected by the virus. The most recent detection was in February 2024. But this is the first time the disease has made cattle in Colorado sick. I’m a veterinarian and epidemiologist at Colorado State University who focuses on infectious diseases in dairy cows. I spent many years...

What makes a city a good place to live? Practical features are important, such as well-maintained streets, good public transit and reliable trash collection. So are amenities that make cities attractive and interesting, such as museums and public parks. Access to green space is especially valuable for residents who may not be able to travel easily beyond city limits. On May 22, 2024, the nonprofit Trust for Public Land released its annual ParkScore report which ranks U.S. cities based on the quality of their parks. Beyond tallying how many parks a city has, the rankings also consider the share of residents who live within 10 minutes’ walk of a park. This recognizes that in the U.S. and other wealthy countries, affluent white neighborhoods often have more parks than low-income areas and communities of color. Access is important, but I believe making people feel included and welcome is equally important. If parks do this well, people will be more willing to use them. I a...

Recent reports that the H5N1 avian flu virus has been found in cow’s milk have raised questions about whether the U.S. milk supply is safe to drink. According to the federal Food and Drug Administration, the answer is yes, as long as the milk is pasteurized. Nonetheless, raw (unpasteurized) milk sales are up, despite health experts’ warning that raw milk could contain high levels of the virus, along with many other pathogens. As an extension food scientist in a state where raw milk sales are legal, I provide technical support to help processors produce high-quality, safe dairy foods. I also like to help people understand the confusing world of pasteurization methods on their milk labels, and why experts strongly discourage consuming raw milk and products made from it. What can make milk unsafe Dairy products, like many foods, have inherent risks that can cause a variety of illnesses and even death. Our milk comes from animals that graze outdoors and live in bar...

America’s first large-scale offshore wind farms began sending power to the Northeast in early 2024, but a wave of wind farm project cancellations and rising costs have left many people with doubts about the industry’s future in the U.S. Several big hitters, including Ørsted, Equinor, BP and Avangrid, have canceled contracts or sought to renegotiate them in recent months. Pulling out meant the companies faced cancellation penalties ranging from US$16 million to several hundred million dollars per project. It also resulted in Siemens Energy, the world’s largest maker of offshore wind turbines, anticipating financial losses in 2024 of around $2.2 billion. Altogether, projects that had been canceled by the end of 2023 were expected to total more than 12 gigawatts of power, representing more than half of the capacity in the project pipeline. So, what happened, and can the U.S. offshore wind industry recover? Estimates...
