Scientists know that air pollution particles from mid-latitude cities migrate to the Arctic and form an ugly haze, but a new University of Utah study finds surprising evidence that polar explorers saw the same phenomenon as early as 1870.
“The reaction from some colleagues — when we first mentioned that people had seen haze in the […]
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander — increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil — but it didn’t. What researchers found instead was that […]
Earth’s land cover has been charted from space before, but this map, which will be made available to the public upon its completion in July, has a resolution 10 times sharper than any of its predecessors.
Scientists, who will use the data to plot worldwide land-cover trends, study natural and managed ecosystems and to model climate […]
Scientists recently developed a new modeling approach to estimate sea ice thickness. This is the only model based entirely on historical observations. The model was developed by scientists with the US Geological Survey and the Russian Academy of Sciences, Moscow.
Spring in the Rockies begins when the snowpack melts. But with the advent of global climate change, the snow is gone sooner. Some of the region’s wildflowers are blooming less because of it. Three flowers found in the Rockies are far more susceptible to late frost damage when the snow melts more quickly.
