Scripps-led Global Ocean Warming Research Paper Published in Science
June 03, 2005Research led by scientists at Scripps Institution of Oceanography at the University of California, San Diego, that describes the first clear evidence of human-produced warming in the world's oceans will be published June 2, 2005, in the peer-reviewed journal Science.
The research was first announced publicly and widely publicized in February at a news briefing at the annual meeting of the American Association for the Advancement of Science in Washington, D.C. (For details, see http://scrippsnews.ucsd.edu/article_detail.cfm?article_num=666)
The paper's abstract notes: "A warming signal has penetrated into the world's oceans over the past 40 years. The signal is complex, with a vertical structure that varies widely by ocean; it cannot be explained by natural internal climate variability or solar and volcanic forcing, but is well simulated by two anthropogenically forced climate models. (The authors) conclude it is of human origin, a conclusion robust to observational sampling and model differences. Changes in advection combine with surface forcing to give the overall warming pattern. The implications of this study suggest society needs to seriously consider model predictions of future climate change."

Ocean Warming Current Events and Ocean Warming News RSSStudy: Sea stars bulk up to beat the heat
A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide.
Warming ocean contributes to global warming
The warming of an Arctic current over the last 30 years has triggered the release of methane, a potent greenhouse gas, from methane hydrate stored in the sediment beneath the seabed.
Andrill demonstrates climate warming affects Antarctic ice sheet stability
A five-nation scientific team has published new evidence that even a slight rise in atmospheric concentrations of carbon dioxide, one of the gases that drives global warming, affects the stability of the West Antarctic Ice Sheet (WAIS).
The Agulhas Current, in the southern hemisphere, may influence climate in Europe
Her PhD thesis "Surface and Deep Circulation off South Africa: Agulhas Leakage Influence on the Meridional Overturning Circulation During the Last 345 kyr" presented data on a major ocean current in the southern hemisphere, the Agulhas Current, which transports warm waters from the tropical Indian Ocean to the southern tip of Africa.
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.
Earth's seasons now arrive 2 days earlier, UC Berkeley, Harvard researchers report
Not only has the average global temperature increased in the past 50 years, but the hottest day of the year has shifted nearly two days earlier, according to a new study by scientists from the University of California, Berkeley, and Harvard University.
Scientific sub makes deep-sea discoveries
A four-week expedition to explore the deep ocean south-west of Tasmania has revealed new species of animals and more evidence of impacts of increasing carbon dioxide on deep-sea corals.
Measuring water from space
Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions.
Ocean warming on the rise
Increased scientific confidence that ocean observations are accurately reflecting rising global temperatures is central to new Australian research published today in the journal, Nature.
Ocean temperatures and sea level increases 50 percent higher than previously estimated
New research suggests that ocean temperature and associated sea level increases between 1961 and 2003 were 50 percent larger than estimated in the 2007 Intergovernmental Panel on Climate Change report.

Our Changing Climate: The Oceans by Laurie Goldman (Author), Erin Hunter (Illustrator) You've heard the newsthe world is getting warmer. Even the very largest of ecosystems, our oceans, are feeling the heat. The oceans cover more than 70 percent of the globe. They are home to more than 80 percent of life on Earth from seaweed to sharks. They store heat. They regulate our weather. They provide much of our food. Many of our cities hug their shores. Stellar science writer Laurie Goldman describes how Earth is responding to climate change and what it means for our future. Packed with dozens of full-color photographs and illustrations. |

Global Warming, Ocean Circulation, and the Carbon Cycle: An Integrated Modeling Study by Long Cao (Author) Global warming is one of the most urgent environmental problems facing us today. A reliable projection of future climate change requires an accurate prediction of atmospheric CO2 concentrations, which depends on CO2 emissions and its absorption by the ocean and terrestrial biosphere. Here we use an earth system model to investigate how increasing atmospheric CO2 concentrations and climate change would modify the physical, chemical, and biological properties of the ocean, and how they affect the ability of ocean to continue act as a carbon sink. A number of issues regarding climate change, ocean circulation, the carbon cycle, and their numerical modeling are discussed. This book should help to improve our understanding of the interactions between global warming and the carbon cycle, and... |
