COLLEGE PARK, Md. – A majority of Americans professing belief in God favor cooperative international efforts to combat climate change and the spread of nuclear weapons, says a new public opinion poll conducted jointly by the University of Maryland’s Center for International and Security Studies at Maryland (CISSM) and its Program on International Policy Attitudes (PIPA).

The nearly 1,500 Americans surveyed include large numbers of Catholics and Evangelicals.

The study, Faith and Global Policy Challenges: How Spiritual Values Shape Views on Poverty, Nuclear Risks, and Environmental Degradation, also finds that a majority of believers consider addressing global poverty a “spiritual obligation,” and think that the United States should work cooperatively with other nations to reduce it.

University of Minnesota professor is part of international team that predicts the volatile region’s water may once again vanish

MINNEAPOLIS / ST. PAUL — An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period similar to predicted scenarios for climate change in coming decades. Emi Ito, professor of earth sciences in the University of Minnesota’s College of Science and Engineering, is a research team member. (more…)

PASADENA, Calif. – NASA and Ohio State University researchers have discovered the major tsunami generated by the March 2011 Tohoku-Oki quake centered off northeastern Japan was a long-hypothesized “merging tsunami.” The tsunami doubled in intensity over rugged ocean ridges, amplifying its destructive power at landfall.

While the worst drought since the Dust Bowl of the 1930s grips Oklahoma and Texas, scientists are warning that what we consider severe drought conditions in North America today may be normal for the continent by the mid-21^st century, due to a warming planet.

A team of scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab), Lawrence Livermore National Laboratory (LLNL), and the National Oceanic and Atmospheric Administration (NOAA) came to this conclusion after analyzing 19 different state-of-the-art climate models. Looking at the balance between precipitation and evapotranspiration—the movement of water from soil to air—they found that no matter how rainfall patterns change over the next 100 years, a warming planet leads to drought. Their results were published in the December 2011 issue of the American Meteorological Society’s Journal of Hydrometerology. (more…)

Researchers Assess Radioactivity Released to the Ocean from the Fukushima Dai-Ichi Nuclear Power Facility

With news this week of additional radioactive leaks from Fukushima nuclear power plants, the impact on the ocean of releases of radioactivity from the plants remains unclear. But a new study by U.S. and Japanese researchers analyzes the levels of radioactivity discharged from the facility in the first four months after the accident and draws some basic conclusions about the history of contaminant releases to the ocean.

Report evaluates amount of carbon absorbed by wetlands, grasslands and forests in the Great Plains region

WASHINGTON, D.C. — The Department of the Interior today released the first in a series of regional studies measuring the amount of carbon stored in U.S. ecosystems. Published by Interior’s U.S. Geological Survey (USGS), the study examines the current and projected future carbon storage in the Great Plains region, as part of a nation-wide assessment. (more…)

UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.

The research, federally funded by the National Science Foundation, is published Dec. 2 in the journal Science.

The team’s groundbreaking integral projection model, or IPM, unites various sub-disciplines of population biology, including population ecology, quantitative genetics, population genetics, and life-span and offspring information, allowing researchers to link many different data sources simultaneously. Scientists can now change just a single variable, like temperature, and see how that affects many factors for a population. (more…)
