Precipitation Cycle Enhanced in Recent Years
March 14, 2013 | Nature Geoscience

The annual range of precipitation has increased across the globe, mostly due to the fact that wet seasons have become wetter, according to a new study published in Nature Geoscience. Using observations of seasonal precipitation extremes over the past 30 years, the authors found no change in annual...


Saharan Dust Influences Sierra Nevada Precipitation
March 7, 2013 | Science

Dust from the Sahara desert and Asia influences precipitation in the Sierra Nevada of California, precipitation that the region counts on for its water supply, according to a new study published in Science. The particles of dust, which other studies have shown to be capable of traveling around the world,...


Ability to Work Outside Diminishes as Climate Warms
March 7, 2013 | Nature Climate Change

The capacity of an individual to safely perform sustained labor under heat stress (labor capacity) has already decreased by 10 percent globally over the past few decades, and is predicted to decrease by another 10 percent by 2050 due to increasing temperatures and humidity. Authors of a recent study...


Arguments Advanced for Climate-Change Influence on Superstorm Sandy
March 7, 2013 | Oceanography

Superstorm Sandy may have been influenced by Arctic sea ice loss caused by human-induced climate changes, according to an article in Oceanography. Many factors played a role in creating the conditions needed to produce the superstorm, according to the authors: 1) unusually warm ocean temperatures maintained...


Flowers Coming Earlier, Especially in the North
March 7, 2013 | Geophysical Research Letters

Increasing temperatures may lead to an earlier spring bloom in the U.S. by as much as several weeks, according to a new study in Geophysical Research Letters based on data from the USA National Phenology Network and model simulations. The authors argue that these changes could significantly affect how much...


Winter Storms Bring Much-Needed Precipitation to AZ
February 28, 2013 | CLIMAS

It was a tale of two states over the past 30 days, with cold, wet conditions in most of Arizona and warm, dry conditions in most of New Mexico, according to the February Southwest Climate Outlook from CLIMAS. Five winter storms brought above-average precipitation to many parts of Arizona over the past month, and...


Feds Assess Resource Conditions on Colorado Plateau

The U.S. Bureau of Land Management has issued a Rapid Ecoregional Assessment (REA) for the Colorado Plateau region in the hopes of developing collaborative management efforts across administrative boundaries and to...


SW Water Basins Extremely Vulnerable to Future Changes
February 28, 2013 | U.S. Forest Service

Water systems in the Southwest are among the most vulnerable to future climatic and socio-economic changes, according to a recent study by the U.S. Forest Service in collaboration with researchers at Colorado State University and Princeton University. The authors evaluated the vulnerability of water systems around the country based on...


Adaptation Plan Helps SW Scientists, Managers Address Climate Change
February 28, 2013 | Conservation Biology

Scientists with the Southwest Climate Change Initiative have piloted a new collaborative planning approach aimed to help natural resource managers more effectively coordinate across jurisdictional boundaries to plan for and create management actions to address the future effects of climate change in the Southwest U.S. The approach, entitled Adaptation for Conservation Targets (ACT), is...


January Was Cold, Wet in the SW
February 22, 2013 | NOAA

Although January temperatures as a whole were well above average for the contiguous U.S., the Southwest experienced colder-than-average temperatures, with Utah and Nevada experiencing their eighth and ninth coolest January on record, respectively, according to the latest State of the Climate report from NOAA. But for the 12-month...
