The Decline and Fall of the Emperor Penguin?Woods Hole Oceanographic Institution | 22 Nov 2013
At nearly four feet tall, the Emperor penguin is Antarcticas largest seabird—and thanks to films like March of the Penguins and Happy Feet, its also one of the continents most iconic. If global temperatures continue to rise, however, the large colony of emperor penguins in Terre Adélie in East Antarctica may eventually disappear, according to a study led by researchers from the Woods Hole Oceanographic Institution (WHOI).
Methane-munching microorganisms meddle with metalsEurekAlert | 11 Nov 2013
(Georgia Institute of Technology) A pair of microbes on the ocean floor "eats" methane in a unique way, and a new study provides insights into their surprising nutritional requirements. Learning how these methane-munching organisms make a living in these extreme environments could provide clues about how the deep-sea environment might change in a warming world.
Is global heating hiding out in the oceans?EurekAlert | 01 Nov 2013
(The Earth Institute at Columbia University) In a reconstruction of Pacific Ocean temperatures in the last 10,000 years, researchers have found that its middle depths have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000.
Global warming as viewed from the deep oceanEurekAlert | 01 Nov 2013
(Rutgers University) Yair Rosenthal of Rutgers, Braddock Linsley of Columbia University's Lamont-Doherty Earth Observatory, and Delia W. Oppo of the Woods Hole Oceanographic Institution, used the shells of tiny single-celled, bottom-dwelling foraminifera found in sediment cores to reconstruct the Pacific Ocean's heat content over the last 10,000 years. Their paper has been published in Science.
New study suggests coral reefs may be able to adapt to moderate climate changeEurekAlert | 30 Oct 2013
(NOAA Headquarters) Coral reefs may be able to adapt to moderate climate warming, improving their chance of surviving through the end of this century, if there are large reductions in carbon dioxide emissions, according to a study funded by NOAA and researched by the agency's scientists and its academic partners. Results further suggest corals have already adapted to part of the warming that has occurred.
El Niño is becoming more activeEurekAlert | 29 Oct 2013
A new approach to analyzing geological and biological clues from the past to reconstruct El Niño activity during the past 600 years resolves disagreements and reveals that El Niño has become more active in recent decades. The work, published in Climate of the Past by scientists from the University of New South Wales and the University of Hawaii International Pacific Research Center, may also help yield more accurate El Niño projections with further global warming.
Irukandji threat to southern watersEurekAlert | 29 Oct 2013
Researchers from Griffith University's Australian Rivers Institute have conducted a series of climate change simulation experiments to investigate whether the dangerous tropical jellyfish, the Irukandji, is likely to establish breeding populations in the South East. It was found that while higher sea temperatures could provide an opportunity for adult Irukandji to expand their range south, increasing ocean acidification may inhibit the development of juveniles.
CU-Boulder study shows unprecedented warmth in ArcticEurekAlert | 25 Oct 2013
(University of Colorado at Boulder) Average summer temperatures in the Eastern Canadian Arctic during the last 100 years are higher now than during any century in the past 44,000 years and perhaps as long ago as 120,000 years, says a new University of Colorado Boulder study.
Scientists give strongest climate change warningNew Zealand Herald | 23 Sep 2013
Scientists will this week issue their starkest warning yet about the mounting dangers of global warming. In a report to be handed to political leaders in Stockholm tonight, they will say that the burning of fossil fuels and deforestation have led to a warming of the globe, including land surfaces, oceans and the atmosphere.
Global warming could change strength of El NiñoEurekAlert | 12 Sep 2013
(University of New South Wales) Global warming could impact the El Niño Southern Oscillation, altering the cycles of El Niño and La Niña events that bring extreme drought and flooding to Australia and many other Pacific-rim countries.
Deep-ocean carbon sinksEurekAlert | 06 Sep 2013
(University of Iowa) Although microbes that live in the so-called "dark ocean"-- below a depth of some 600 feet where light doesn't penetrate-- may not absorb enough carbon to curtail global warming, they do absorb considerable amounts of carbon and merit further study, according to a University of Iowa study.
Warming slowdown linked to PacificBBC | 28 Aug 2013
Researchers say that the hiatus in global temperatures over the past 15 years can be explained by colder waters in the tropical Pacific.
Global warming and oceans: what are the known unknowns?Guardian Unlimited | 28 Aug 2013
The world's leading oceanography experts examine global warming and the oceans in Abraham et al. (2013) Understanding how humans are changing the climate requires experts from many different areas. Physicists, chemists, engineers, mathematicians, biologists, atmospheric scientists, oceanographers, social scientists, the list goes on.
Cooling Pacific has dampened global warming, research showsGuardian Unlimited | 28 Aug 2013
Cooling waters in the tropical Pacific Ocean appear to be a major factor in dampening global warming in recent years, scientists said on Wednesday. Their work is a big step forward in helping to solve the greatest puzzle of current climate change research - why global average surface temperatures, while still on an upward trend, have risen more slowly in the past 10 to fifteen years than previously.
Warming Antarctic seas likely to impact on krill habitatsEurekAlert | 22 Aug 2013
(British Antarctic Survey) Antarctic krill are usually less than 6 cm in length but their size belies the major role they play in sustaining much of the life in the Southern Ocean. They are the primary food source for many species of whales, seals, penguins and fish.
NOAA: 2012 was one of the 10 warmest years on record globallynoaanews.noaa.gov | 12 Aug 2013
Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released online today by the American Meteorological Society (AMS). Conditions in the Arctic were a major story of 2012, with the region experiencing unprecedented change and breaking several records.
