Transported black carbon a significant player in Pacific Ocean climate
03-14-2007 · EurekAlert!More than three-quarters of the particulate pollution known as black carbon transported at high altitudes over the West Coast during spring is from Asian sources, according to a research team led by Professor V. Ramanathan at Scripps Institution of Oceanography, UC San Diego.

- Ocean's 'twilight zone' may be a key to understanding climate change
04-27-2007 · EurekAlert!
A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below the surface.

- Corals and climate change
08-22-2007 · EurekAlert!
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals. Fully operational this month, this new lab has begun to study how corals respond to the combined stress of greenhouse warming and ocean acidification. The lab is the first to maintain corals under precisely controlled temperature and carbon dioxide conditions while exposing them to natural light conditions.

- Wildfire drives carbon levels in northern forests
10-31-2007 · EurekAlert!
Far removed from streams of gas-thirsty cars and pollution-belching factories lies another key player in global climate change. Circling the northern hemisphere, the conifer-dominated boreal forests -- one of the largest ecosystems on earth -- act as a vast natural regulator of atmospheric carbon levels.

- The striking deep current reversal in the tropical Pacific Ocean
11-13-2006 · EurekAlert!
In two oceanographic surveys conducted in the south-west Pacific Ocean, in October 1999 and April 2000, scientists from this IRD observed a sharp change in direction of equatorial intermediate current between these two dates. Such temporal variability is not new, but in this case its amplitude is strikingly strong. This effect will have to be taken into account if better understanding of ocean/atmosphere exchanges and climate variations is to be achieved.

- Deep in the ocean, a clam that acts like a plant
02-20-2007 · EurekAlert!
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. Around hydrothermal vents deep in the ocean live communities of giant clams with no gut and no functional digestive system, depending on symbiotic bacteria to use energy locked up in hydrogen sulfide to replace sunlight. Now, the genome of this symbiont has been completely sequenced.

- Arctic climate study reveals impact of industrial soot
08-09-2007 · EurekAlert!
Scientists from the Desert Research Institute and their collaborators have determined that Northern Hemisphere industrial pollution resulted in a seven-fold increase in black carbon in Arctic snow during the late 19th and early 20th centuries. Drs. Joe McConnell and Ross Edwards led the research developing a new technique to quantify the impact of black carbon on Arctic climate forcing.

- Immediate action needed to save corals from climate change
12-13-2007 · EurekAlert!
The journal Science has published a paper today that is the most comprehensive review to date of the effects rising ocean temperatures are having on the world’s coral reefs. "The Carbon Crisis: Coral Reefs under Rapid Climate Change and Ocean Acidification," co-authored by 17 marine scientists from seven different countries, reveals that most coral reefs will not survive the drastic increases in global temperatures and atmospheric CO2 unless governments act immediately to combat current trends.

- Economists help climate scientists to improve global warming forecasts
01-21-2008 · EurekAlert!
Climate scientists are collaborating with experts in economic theory to improve their forecasting models and assess more accurately the impact of rising atmospheric carbon dioxide levels. Although there is broad consensus that there will be a significant rise in average global temperature, there is great uncertainty over the extent of the change, and the implications for different regions.

- Salty oceans provide early warning for climate change
06-08-2007 · EurekAlert!
Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time. Presenting their findings at a recent European Science Foundation (ESF) conference, scientists predicted that the waters of the southern hemisphere oceans around South Africa and New Zealand are the places to watch.
