Snow-dependent regions in the Northern Hemisphere, including the western U.S., are predicted to experience increased stress from low snow years within the next 30 years, according to a recent report in Nature.
Mid-level forests in the western U.S.—at about 6,500 to 8,000 feet—will be particularly sensitive to higher temperatures due to climate change, according to a new study published in Nature Geoscience.
The proportion of precipitation that falls as snow in Utah from January through March has decreased by 9 percent over the past 50 years due to rising temperatures, according to a recent study published in the Journal of Climate.
After analyzing records at 35 headwater basins in the U.S. and Canada, scientists at the Long Term Ecological Research Network find that as temperatures increase in these snowpack regions, a large amount of stream water is lost due to evaporation.
March was 8.6 degrees F warmer than average across the contiguous U.S., making it the warmest March on record with over 15,000 high temperature records broken, according to NOAA. Only one other month has seen a larger departure from its average, January 2006.
New research published in Ecology Letters shows that a single climate parameter, the timing of spring snowmelt, has many different effects on the population growth of the Mormon Fritillar
Dry conditions continued through February in the Southwest—Phoenix tied its driest year-to-date on record—with only small portions of Colorado seeing precipitation above normal, according to the newest State of the Climate from NOAA.
