West Antarctic Ice Sheet ‘Could Be More Stable than Thought’
Whether global warming may cause the giant West Antarctic Ice Sheet to melt and raise sea-levels by several metres is one of the most contested debates in climate science. (more…)

NASA Shows Topography of Tsunami-Damaged Japan City
The topography surrounding Sendai, Japan is clearly visible in this combined radar image and topographic view generated with data from NASA’s Shuttle Radar Topography Mission (SRTM) acquired in 2000. On March 11, 2011, a magnitude 8.9 earthquake struck offshore about 130 kilometers (80 miles) east of Sendai, the capital city of Japan’s Miyagi Prefecture, generating a tsunami that devastated the low-lying coastal city of about 1 million residents.
The city is centered in the image and lies along the coastal plain between the Ohu Mountains and the Pacific Ocean. The eastern part of the city is a low-lying plains area, while the city center is hilly (the city’s official elevation is about 43 meters, or 141 feet). Sendai’s western areas are mountainous, with its highest point being Mt. Funagata at an elevation of about 1,500 meters (4,921 feet) above sea level. (more…)
WHOI Experts Stress Lessons From Japan Earthquake
While Japan’s 8.9-magnitude earthquake and accompanying tsunami represent a devastating natural disaster for the country’s residents, scientists should also seize upon the massive temblor as an important learning tool for future quakes around the world, including the Pacific Northwest coast of the United States, according to experts from the Woods Hole Oceanographic Institution (WHOI).

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.

Researchers Discover New Wintering Grounds for Humpback Whales Using Sound
Researchers at the Hawai‘i Institute of Marine Biology (HIMB), an organized research unit in the University of Hawai‘i at Mānoa’s School of Ocean and Earth Science and Technology have made a remarkable new discovery.
In the thick of whale season, researchers from HIMB and the National Oceanic and Atmospheric Administration (NOAA) shed new light on the wintering grounds of the humpback whale. The primary breeding ground for the North Pacific was always thought to be the main Hawaiian Islands. However, a new study has shown that these grounds extend all the way throughout the Hawaiian Archipelago and into the Northwestern Hawaiian Islands (NWHI), also known as Papahānaumokuākea Marine National Monument (PMNM).

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.
The research team drew from scientific observations and computer climate models to evaluate the possible roles of natural and human-caused climate influences on the severity of the heat wave. The study has been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union. (more…)
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…)
