Research Finds Discrepancies Between Satellite and Global Model Estimates of Land Water Storage

Fri, 01/26/2018 - 09:44
Research led by The University of Texas at Austin has found that calculations of water storage in many river basins from commonly used global computer models differ markedly from independent storage estimates from GRACE satellites.

Tiny Particles Have Outsize Impact On Storm Clouds, Precipitation

Thu, 01/25/2018 - 14:35
Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a study in the Jan. 26 issue of the journal Science.

How To Save a Town From Rising Waters

Thu, 01/25/2018 - 13:34
The only land route that connects Isle de Jean Charles, Louisiana, to the rest of the continental United States is Island Road, a thin, four-mile stretch of pavement that lies inches above sea level and immediately drops off into open water on either side. Even on a calm day, salt water laps over the road’s tenuous boundaries and splashes the concrete.

Nearly Half of California's Vegetation at Risk From Climate Stress

Thu, 01/25/2018 - 13:30
Current levels of greenhouse gas emissions are putting nearly half of California’s natural vegetation at risk from climate stress, with transformative implications for the state’s landscape and the people and animals that depend on it, according to a study led by the University of California, Davis. However, cutting emissions so that global temperatures increase by no more than 2 degrees Celsius (3.2 degrees Fahrenheit) could reduce those impacts by half, with about a quarter of the state’s natural vegetation affected.

Record Jump in 2014-2016 Temps Largest Since 1900

Thu, 01/25/2018 - 08:10
Global surface temperatures surged by a record amount from 2014 to 2016, boosting the total amount of warming since the start of the last century by more than 25 percent in just three years, according to new University of Arizona-led research.

Rise in severity of hottest days outpaces global average temperature increase

UCI study also finds megacities affected most by uptick in extreme-heat events

Less predictable precipitation

Waning influence of once-telling weather patterns altered by global warming skews projections.

UW Researcher Leads Study of First Quantifiable Observation of Cloud Seeding

Wed, 01/24/2018 - 11:49
A University of Wyoming researcher contributed to a paper that demonstrated, for the first time, direct observation of cloud seeding -- from the growth of the ice crystals through the processes that occur in the clouds to the eventual fallout of the ice crystals that become snow -- and how the impacts could be quantified.

Stanford Researcher: Interacting Antarctic Glaciers May Cause Faster Melt and Sea Level Contributions

Wed, 01/24/2018 - 09:33
A new study shows that a large and potentially unstable Antarctic glacier may be melting farther inland than previously thought and that this melting could affect the stability of another large glacier nearby – an important finding for understanding and projecting ice sheet contributions to sea-level rise.

From the eruption of the Timanfaya volcano in the Canary Islands to the coniferous forests in the Pyrenees

Tue, 01/23/2018 - 16:58
The chemical traces from the released gases into the atmosphere by eruptions such the Timanfaya’s can be now identified in the oldest coniferous Pyrenean forests.

Climate Change and Snowmelt - Turn Up the Heat, but What About Humidity?

Mon, 01/22/2018 - 16:36
It’s said on sticky summer days: “It’s not the heat, it’s the humidity.” That holds true in the winter too, and could hold the key to the future of snowpack and water resources in the American West.

Climate change linked to more flowery tropical forests, FSU study shows

Mon, 01/22/2018 - 11:19
New research from a Florida State University scientist has revealed a surprising relationship between surging atmospheric carbon dioxide and flower blooms in a remote tropical forest.

Climate Engineering, Once Started, Would Have Severe Impacts If Stopped

Mon, 01/22/2018 - 11:07
Facing a climate crisis, we may someday spray sulfur dioxide into the upper atmosphere to form a cloud that cools the Earth, but suddenly stopping the spraying would have a severe global impact on animals and plants, according to the first study on the potential biological impacts of geoengineering, or climate intervention.

A climate science milestone on Colorado's Continental Divide

Mon, 01/22/2018 - 08:31
On January 16, 1968, in a bracing chill at 11,568 feet above sea level, a Colorado researcher collected an air sample at Niwot Ridge, on the doorstep of the Indian Peaks mountain range. The sample was carried down the mountain and then measured for carbon dioxide at a lab in Boulder, Colorado. The result: 322.4 parts per million.

Scientists, volunteers rescue about 1,000 cold-stunned sea turtles

Mon, 01/22/2018 - 08:31
On the icy cold shores of Florida’s St. Joseph Bay, a team of volunteers and wildlife experts have rescued an estimated 1,000 cold-stunned sea turtles since January 2 in what is believed to be Florida’s second-largest mass cold-stunning event of the 21st century, according to U.S. Geological Survey research biologist Margaret Lamont. 

Methane from Indian Livestock Adds to Global Warming

Fri, 01/19/2018 - 09:55
Methane produced by India’s livestock population, considered the world’s largest, can significantly raise global temperatures, says a new study designed to help predict climate change linked to greenhouse gas (GhG) emissions from farm animals.

Climate Change Affects Fish Reproductive Phenology in Plateau Area: Study

Fri, 01/19/2018 - 09:46
Climate change has threatened the global environment and biodiversity, particularly the aquatic ecosystems as well as the development of human ecosociety. The Tibetan Plateau is the region possessing the richest water resources in Asia but highly affected by the global climate change.

Mining weather data from Civil War-era Navy logbooks

Fri, 01/19/2018 - 09:34
A new grant will let a University of Washington-based project add a new fleet to its quest to learn more about past climate from the records of long-gone mariners. The UW is among the winners of the 2017 “Digitizing Hidden Special Collections and Archives” awards, announced earlier this month by the Washington, D.C.-based Council on Library and Information Resources.             

Crop Failure in the Andes

Thu, 01/18/2018 - 14:46
Kenneth Feeley, the Smathers Chair of Tropical Tree Biology in the University of Miami’s Department of Biology, is an expert in studying the effects of climate change on tropical forests. From the mountains of Peru to the lowlands of the Amazon, Feeley examines the ramifications of climate change on the trees and other species that comprise the diverse forests of these regions. Yet, recently, Feeley shifted gears from studying tropical forests to examining the impacts of climate change in rural farming communities in Peru.

NASA Sees Tropical Cyclone Berguitta Soaking Mauritius and Reunion Island

Thu, 01/18/2018 - 14:18
NASA found heavy rainfall in Tropical Cyclone Berguitta as it closed in on Mauritius and Reunion Islands. On Jan. 18, NASA's Terra satellite captured an early morning visible image that showed the center of the storm just south of Mauritius and the storm blanketing both islands. Warnings were in effect for both islands. A tropical cyclone alert class 3 is in effect for Mauritius and La Reunion is on Orange Alert.
