Diverse forests are stronger against drought

September 17, 2018

Diversity is strength, even among forests. In a paper published in Nature, researchers led by University of Utah biologist William Anderegg report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual […]



Drought, migration and violence in Kenya

September 10, 2018

As droughts worsen across the globe, more people who earn their living through farming and owning livestock are forced to leave their homes. Many academics and policymakers predict that the rise in migration may lead to an increase in violent conflict. However, most existing studies on the topic use country-level or regional data that fail […]



Birds retreating from climate change, deforestation in Honduras cloud forests

September 6, 2018

The cloud forests of Honduras can seem like an otherworldly place, where the trees are thick with life that takes in water straight from the air around it, and the soundscape is littered with the calls of animals singing back and forth. Otherworldly, yes, but scientists have found that the cloud forests are not immune […]



An easier way to simulate cloud cover

July 19, 2018

Take a look at the clouds, if there are any in your sky right now. If not, here are a few examples. Watch the billows, the white lofty tufts set against the blue sky. Or, depending on your weather, watch the soft grey edges smear together into blended tones that drag down through the air […]



Dust on snow controls springtime river rise in West

January 25, 2018

A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River. Contrary to conventional wisdom, the amount of dust on the mountain snowpack controls how fast the Colorado Basin’s rivers rise in the spring regardless of air temperature, with more dust correlated […]



Arctic clouds highly sensitive to air pollution

January 3, 2018

In 1870, explorer Adolf Erik Nordenskiöld, trekking across the barren and remote ice cap of Greenland, saw something most people wouldn’t expect in such an empty, inhospitable landscape: haze. Nordenskiöld’s record of the haze was among the first evidence that air pollution around the northern hemisphere can travel toward the pole and degrade air quality […]



What it takes to recover from drought

August 3, 2017

Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground. According to a study published August 10 in Nature, the length of drought recovery depends on several factors, including the region of the world and the post-drought weather conditions. The […]



Woodrats can’t stomach favorite foods at high temps

June 27, 2017

You’d think desert woodrats already had a lot of adversity. Besides the constant threat of coyotes and other predators and the scorching Mojave Desert heat, their primary source of food is the creosote bush, or chaparral – a plant so toxic that few other animals will even go near it. But the woodrats’ unique adaptation […]



Weather patterns’ influence on frost timing

May 18, 2017

Gardeners know the frustration of a false spring. Coaxed outside by warm weather, some people plant their gardens in the spring only to see a sudden late frost strike at the plants with a killer freezer burn. Grumbling green thumbs, along with farmers and water supply managers, would benefit from more accurate predictions of the […]



What global climate change may mean for leaf litter in streams and rivers

March 2, 2017

Carbon emissions to the atmosphere from streams and rivers are expected to increase as warmer water temperatures stimulate faster rates of organic matter breakdown. But a new study led by University of Utah researcher Jennifer J. Follstad Shah, in collaboration with a team of 15 scientists in the U.S. and Europe, suggests these decay rates […]
