Commercial ships spew half as much particulate pollution as world's cars
Globally, commercial ships emit almost half as much particulate pollution into the air as the total amount released by cars, according to a new study published on Feb. 25, 2009 in the Journal of Geophysical Research -- Atmospheres, a publication of the American Geophysical Union. Ship pollutants affect both the Earth's climate and the health of people living along coastlines.

Study shows maritime shipping makes hefty contribution to air pollution
Commercial ships emit almost half as much particulate pollutants into the air globally as the total amount released by the world's cars, according to a new study led by the National Oceanic and Atmospheric Administration and the University of Colorado at Boulder.

CO2 drop and global cooling caused Antarctic glacier to form
Global climate rapidly shifted from a relatively ice-free world to one with massive ice sheets on Antarctica about 34 million years ago. What happened? What changed? A team of scientists led by Yale geologists offers a new perspective on the nature of changing climatic conditions across this greenhouse-to-icehouse transition -- one that refutes earlier theories and has important implications for predicting future climate changes.

US-led international research team confirms Alps-like mountain range exists
Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a US-led, international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice.

Lower increases in global temps could lead to greater impacts than previously thought, study finds
A new study by scientists updating the findings of the Intergovernmental Panel on Climate Change 2001 Third Assessment Report finds that even a lower level of increase in average global temperatures due to greenhouse gas emissions could cause significant problems in five key areas of global concern.

Changing sexes on the sea floor
Trees do it. Bees do it. Even environmentally stressed fish do it. But Prof. Yossi Loya from Tel Aviv University's Department of Zoology is the first in the world to discover that Japanese sea corals engage in "sex switching" too.

Scientists find black gold amidst overlooked data
About half of the oil in the ocean bubbles up naturally from the seafloor, with Earth giving it up freely like it was of no value. Likewise, NASA satellites collect thousands of images and 1.5 terabytes of data every year, but some of it gets passed over because no one thinks there is a use for it.

Erosion rates double along portion of Alaska's coast
Skyrocketing coastal erosion occurred in Alaska between 2002 and 2007 along a 40-mile stretch of the Beaufort Sea, a new study finds. The surge of erosion in recent years, averaging more than double historical rates, is threatening coastal towns and destroying Alaskan cultural relics.

IODP to operate 3 drilling platforms in 2009
The Integrated Ocean Drilling Program will conduct scientific ocean drilling operations aboard all three of its platforms in 2009, from March until December. This is the first time since IODP began operations in 2004 that all three platforms will operate at the same time. Riser drilling will be conducted aboard the Chikyu; the newly modernized JOIDES Resolution will conduct riserless operations; mission-specific operations will be conducted using platforms customized for specific environments.

Historical photographs expose decline in Florida's reef fish, new Scripps study finds
A unique study by a scientist at Scripps Institution of Oceanography at UC San Diego has provided fresh evidence of fishing's impact on marine ecosystems. Scripps Oceanography graduate student researcher Loren McClenachan accessed archival photographs spanning more than five decades to analyze and calculate a drastic decline of so-called "trophy fish" caught around coral reefs surrounding Key West, Florida.

State of the steric sea level rise, 1955-2003
Based on a detailed analysis of ocean vertical temperature profiles for the 1955-2008 period, Sydney Levitus, lead author, talks about the change of global average sea level induced by the observed warming of the world ocean during the past 53 years. The warming of the world ocean is consistent with the amount of warming expected as a result of the observed increase in greenhouse gases in earth's atmosphere.

Cardiac fibrillation of the climate
In the current issue of the scientific journal Nature Geoscience a group of Norwegian, Swiss and German geoscientists prove that before the set-in of the Holocene very rapid climate changes already existed. The transition from the stable cold period took place about 12,150 to 11,700 years ago with very rapid fluctations up to the temperature-threshold at which the Holocene began.

When fish farms are built along the coast, where does the waste go?
Commercial fish pens are placed in the open waters of oceans and bays with no reliable method of predicting where the waste plume will be carried by winds, currents and tides. This can lead to damage to fragile coastline environments. As state and federal regulators begin to draw up rules for fish pens, Stanford's fluid dynamics modeling system can provide answers.

Past trends in hurricane activity and inferences for the future

Climate change likely to be more devastating than experts predicted, warns top IPCC scientist
Without decisive action, global warming is likely to accelerate at a much faster pace and cause more environmental damage than predicted, says Stanford scientist Chris Field, a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change. Field warns that higher temperatures could ignite tropical forests and melt the Arctic tundra, releasing billions of tons of greenhouse gas that could raise temperatures even more -- a vicious cycle that could spiral out of control.
