Farmers struggling to adapt to rising temperatures in tropical regions can unleash the benefits of natural cooling, alongside a host of other wins, simply by dotting more trees across their pasturelands. For the first time, a study led by the University of Washington puts tangible numbers to the cooling effects of this practice. Researchers at the UW and The Nature Conservancy, along with Duke University, the University of California San Diego and Stony Brook University Hospital, find that adding trees to pastureland, technically known as silvopasture, can cool local temperatures by up to 2.4 C (4.3 F) for every 10 metric tons of woody material added per hectare (about 4 tons per acre) depending on the density of trees, while also delivering a range of other benefits for humans and wildlife. 

In an age of rapidly advancing technology, humans are fascinated with AI, which is shorthand for artificial intelligence. Many movies and TV shows feature this techno-wizardry, whether it’s AI beings starring in our favorite Marvel movies or the creation of deeply imaginative worlds that depict post-apocalyptic robot takeovers. The idea of deep learning machines is one we often think about in fictional contexts, but at the University of Washington researchers are looking at practical, real-world applications. 

Pledges made in Glasgow at the recent United Nations Climate Change Conference, or COP26, are urgently needed by communities on the front lines of forest loss, according to a new study by a multidisciplinary team from the University of Washington, Duke University and The Nature Conservancy. New research shows how much local temperature rises in the tropics — compounded by accelerating deforestation — may already be jeopardizing the well-being and productivity of outdoor workers.
