How cold did Earth get during the last ice age? The truth may lie deep beneath lakes and could help predict how the planet will warm again.

Governments across the U.S. and Canada have made strides in their food systems planning efforts, with many recognizing within the past decade that the issue of food insecurity is just as important as maintaining other public infrastructure like roads and water systems.

To assess long-range risks to food, water, energy and other critical natural resources, decision-makers often rely on Earth-system models capable of producing reliable projections of regional and global environmental changes spanning decades.

Beneath the Amargosa desert of the southwest United States lies a hidden gem for climate research. The Devils Hole cave system, named after its bottomless depths, provides a window into the vast desert aquifer below. The cave system is home to a peculiar type of calcite deposit. As groundwater slowly passes through the cave, calcite precipitates layer by layer on the rock walls. "These thin layers have been accumulating on the walls for nearly one million years," explains Kathleen Wendt from the Quaternary Research Group in the Department of Geology at the University of Innsbruck. "The height of ancient deposits in Devils Hole cave tell us how high the water table was in the past."
