A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, according to authors of a new study.

A new study finds the fires that spread throughout North America last summer burned so powerfully their smoke pushed all the way into the stratosphere, circled the globe in roughly two weeks and remained in the stratosphere at measurable levels for several months.

A new study identifies a method for predicting the likelihood of damaging hailstorms in the United States—up to three weeks in advance. Hail is the most economically destructive hazard posed by severe thunderstorms, producing on average billions of dollars in U.S. losses each year, including damage to roofs, homes and especially crops.

A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River.

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

Seismic waves generated by tornadoes when they touch down could be used to measure a twister’s intensity, according to a new study that examined the May 2011 Joplin tornado. The findings could open the door to devising more accurate methods to study tornadoes from the ground.

In April of 1815, the volcanic eruption of Mount Tambora in Indonesia caused a global decrease in temperatures for the following few years, and 1816 came to be known as the “year without a summer.” New England states were particularly hard hit by these temperature changes, which significantly affected agriculture production and quality of life. Alongside his journal entries, Reverend Jonathan Fisher of Blue Hill, Maine sketched the sunspots during the summer of 1816, thinking they might be responsible for the cold summer temperatures.

Offshore wind turbines built according to current standards may not be able to withstand the powerful gusts of a Category 5 hurricane, creating potential risk for any such turbines built in hurricane-prone areas, new University of Colorado Boulder-led research shows. The study, which was conducted in collaboration with the National Center for Atmospheric Research in Boulder, Colorado and the U.S. Department of Energy’s National Renewable Energy Laboratory in Golden, Colorado, highlights the limitations of current turbine design and could provide guidance for manufacturers and engineers looking to build more hurricane-resilient turbines in the future.

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.

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.
