A new study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. The wave persisted for four months, with ice from upstream continuing to move down to replace the missing mass for at least four more months.

In summer 2010, Los Angeles was losing about 100 gallons of water per person per day to the atmosphere through the evaporation and plant uptake of lawns and trees, new research finds. Lawns accounted for 70 percent of the water loss, while trees accounted for 30 percent, according to a new study.

Clumps of microbes can survive in space for at least a year – and perhaps longer, according to Japanese researchers conducting an experiment on board the International Space Station (ISS).
Scientists have developed snapshots of the likelihood of major earthquakes occurring in megacities around the world using a new statistical approach for estimating earthquake risk. The new technique, called seismic nowcasting, estimates the progress of a defined seismically-active geographic region through its repetitive cycle of major earthquakes.
High levels of radioactive cesium remain in the soil near the Fukushima Daiichi nuclear power plant and these radionuclides have migrated at least 5 centimeters down into the ground at several areas since the nuclear accident five years ago, according to preliminary results of a massive sampling project being presented at the JpGU-AGU joint meeting in Chiba, Japan.

Growing plants and then storing the carbon dioxide they have taken up from the atmosphere is not a viable option to counteract unmitigated emissions from fossil fuel burning, a new study shows. Plantations would need to be so large they would eliminate most natural ecosystems or reduce food production if implemented as a late-regret option in the case of substantial failure to reduce emissions, according to the study.

A new study from researchers at UCLA and the University of Houston reveals estimates of significant groundwater loss in California’s Central Valley during the recent drought and sparks questions of sustainability for the important agricultural area.

Since the mid-1980s, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years, according to a new study. While this decline was driven in part by the transition from an unusually wet period to an unusually dry period, rising temperatures deepened the trend.

People living in the American Southwest have experienced a dramatic increase in windblown dust storms in the last two decades, likely driven by large-scale changes in sea surface temperature in the Pacific Ocean drying the region’s soil, according to new NOAA-led research. With the increase in dust storms, scientists have also documented a spike in Valley fever, an infectious disease caught by inhaling a soil-dwelling fungus found primarily in the Southwest.

Global temperatures could break through the 1.5°C barrier negotiated at the Paris conference as early as 2026 if a slow-moving, natural climate driver known as the Interdecadal Pacific Oscillation (IPO) has, as suspected, moved into a positive phase.
