New interactive map models dust exposure from shrinking Great Salt Lake
Most people can imagine why a shrinking Great Salt Lake would mean unhealthy dust storms for the Wasatch Front, or why refilling the lake through water conservation could reduce dust exposure. Now, there is a data-based modeling tool to visualize…

New temperature record challenges extreme high-latitude warmth paradigm
Reliable predictions of how the Earth’s climate will respond as atmospheric carbon dioxide levels increase are based on climate models. These models, in turn, are based on data from past geological times in which the CO2 content in the Earth’s…
