MAGIC Launches For Yearlong Climate Study
2012-10-01 16:21:46

Climate instruments mounted aboard the Horizon Spirit container ship begin taking data A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by U.S. Department of Energy (DOE) scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data today for a yearlong mission aimed at improving the representation of clouds in climate models. The study, a collaborative effort between DOE´s Atmospheric Radiation...

Predictions Put To The Test By Climate Scientists
2012-09-19 08:21:49

A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales. Climate-prediction models show skills in forecasting climate trends over time spans of greater than 30 years and at the geographical scale of continents, but they deteriorate when applied to shorter time frames and smaller geographical regions, a new study has found....

A new record of past temperature change in the tropical Atlantic Ocean's subsurface provides clues as to why the Earth's climate is so sensitive to ocean circulation patterns, according to climate scientists at Texas A&M University. Geological oceanographer Matthew Schmidt and two of his graduate students teamed up with Ping Chang, a physical oceanographer and climate modeler, to help uncover an important climate connection between the tropics and the high latitude North Atlantic....

Though worries about "nuclear winter" have faded since the end of the Cold War, existing stockpiles of nuclear weapons still hold the potential for devastating global impacts. Researchers at the University of Wisconsin—Madison and Rutgers University have found that the climate effects of a hypothetical nuclear war between India and Pakistan would greatly reduce yields of staple crops, even in distant countries. The work, by Mutlu Ozdogan and Chris Kucharik of the Center for...

Analysis Shows Big, Fast Changes Ahead For Global Fire Risk
2012-06-12 15:20:51

Climate change is widely expected to disrupt future fire patterns around the world, with some regions, such as the western United States, seeing more frequent fires within the next 30 years, according to a new analysis led by researchers at the University of California, Berkeley, in collaboration with an international team of scientists. By the end of the century, almost all of North America and most of Europe is projected to see a jump in the frequency of wildfires, primarily because of...

Atmospheric Warming Intensifies Earth’s Water Cycle
2012-05-22 04:29:42

Australian scientists from the Lawrence Livermore National Laboratory in California and the Commonwealth Scientific and Industrial Research Organization (CSIRO) report that in the last fifty years, salinity levels in the world´s oceans have shifted and that climate change is affecting global rainfall and evaporation cycles. According to the lead author of the study, Dr. Paul Durack, researchers looked at the correlations between salinity, rainfall, and evaporation in climate models...

Steam from a Processing Plant

A new study led by Carrie Schloss, an analyst in environmental and forest sciences at the University of Washington, finds that nine percent of the Western Hemisphere's mammals, and nearly forty percent in particular regions, will fall victim to the changing climate. Some mammals are merely too slow to escape climate change in their natural habitats and are unable to move into different areas. The study seeks to understand if the mammals can actually adapt to these conditions by moving or not....

One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models, according to a new University of Washington study. The finding is important because it helps confirm that models that simulate global warming agree with observations, said Stephen Po-Chedley, a UW graduate student in atmospheric sciences who wrote the paper with...

Climatologists Predict More Extreme Summer Temperatures in 21st Century
2012-02-16 14:32:07

A new report published by an American non-profit research center says that extreme summer temperatures are becoming increasingly commonplace in the United States, a trend that they project will continue throughout the 21st century. Climatologist Phil Duffy led a group of researchers at the Lawrence Livermore National Laboratory (LLNL) in California in analyzing the results of various climate models examining the occurrence of extreme high temperatures in the summer months of June, July and...

Clearing The Air On Cloud Simulations
2011-10-27 08:36:16

Climate models have a hard time representing clouds accurately because they lack the spatial resolution necessary to accurately simulate the billowy air masses. But Livermore scientists and international collaborators have developed a new tool that will help scientists better represent the clouds observed in the sky in climate models. Traditionally, observations from satellites infer the properties of clouds from the radiation field (reflection of sunlight back into space, or thermal...
