Gulf Oil Spill Study Sheds Light On Urban Air Pollution

When a team of researchers from the National Oceanic and Atmospheric Administration and the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences raced to the scene of the BP Deepwater Horizon oil spill to assess the disaster’s impact on air quality last year, they found more than they expected.

Tsunami Waves Crash Into Japan’s North-east After Powerful Quake

The government of Japan has provided a report about the damage caused by a strong earthquake which rocked the north-east of the country on Friday, March 11. The Associated Press reports with reference to Japanese television that the tsunami wave, triggered by the quake, caused significant destruction in the northern part of the country.

The magnitude of the earthquake, which took place in Japan on Friday, was measured 8.8 on Richter scale. Quakes still continue in the capital, Tokyo. The epicenter of the quake was located 382 kilometers to the north-east off Tokyo, at the depth of 10 kilometers. (more…)

Main Culprit of Deadly Russian Heat Wave? Natural Variability

WASHINGTON — The deadly Russian heat wave of 2010 was due to a natural atmospheric phenomenon often associated with weather extremes, according to a new study. And while the scientists could not attribute the intensity of this particular heat wave to climate change, they found that extreme heat waves are likely to become increasingly frequent in the region in coming decades.

It’s all in a Name: ‘Global warming’ versus ‘Climate change’

ANN ARBOR, Mich.— Many Americans are skeptical about whether the world’s weather is changing, but apparently the degree of skepticism varies systematically depending on what that change is called.

According to a University of Michigan study published in the forthcoming issue of Public Opinion Quarterly, more people believe in “climate change” than in “global warming.” (more…)

Earth’s Sixth Mass Extinction: Is It Almost Here?

*Steep decline of many animal species warns that Earth is on the brink*

With the steep decline in populations of many animal species, scientists have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years.

Each of these “Big Five” saw three-quarters or more of all animal species go extinct.

In results of a study published in this week’s issue of journal Nature, researchers report on an assessment of where mammals and other species stand today in terms of possible extinction compared with the past 540 million years.

They find cause for hope–and alarm. (more…)

Drier Conditions Projected to Accelerate Dust Storms in the Southwest

MOAB, Utah — Drier conditions projected to result from climate change in the Southwest will likely reduce perennial vegetation cover and result in increased dust storm activity in the future, according to a new study by scientists with the U.S. Geological Survey and the University of California, Los Angeles. 

The research team examined climate, vegetation and soil measurements collected over a 20-year period in Arches and Canyonlands National Parks in southeastern Utah. Long-term data indicated that perennial vegetation in grasslands and some shrublands declined with temperature increases. The study then used these soil and vegetation measurements in a model to project future wind erosion.  (more…)

Berkeley Scientists at AAAS Highlight Challenges of Meeting State Energy Goals by 2050

California is showing the way for the rest of the nation in terms of reducing greenhouse gas emissions, having set an ambitious goal to reduce these emissions to 80 percent below 1990 levels by the year 2050. Given that energy demand is projected to double by 2050, experts agree that the state will have to dramatically overhaul its energy systems to achieve its greenhouse gas emission goals.

At the 2011 Annual Meeting of the American Association for the Advancement of Science, some of the specific challenges and issue ahead were discussed in a session titled “Portraits of the California Energy System in 2050: Cutting Emissions by 80 Percent.” Contributing to this discussion were two scientists from Berkeley Lab and one from the Energy Biosciences Institute (EBI), in which Berkeley Lab is a partner.
