A 21-year global record of precipitation suggests a decrease in rainfall over the Indian Ocean may signal an approaching strong El Niño. This finding could provide nations most affected by El Niños with earlier warning systems to better prepare for devastating climate changes.
Texas A&M researchers Tom Whitworth and Alex Orsi are designing a customized cyber-atlas for the Southern Ocean, combining historical and recent data to generate tailored maps. The atlas will utilize WOCE data to establish a global ocean baseline for studying decadal variability.
A new study has successfully mapped the global extent of 'iron-limited' ocean regions, which are crucial for understanding how the ocean's biology controls the flow of carbon between the atmosphere and the ocean. These regions were identified by analyzing satellite data on dust deposition and phytoplankton productivity.
The Arctic Oscillation is linked to warmer winters in Scandinavia and Siberia, stratospheric ozone layer thinning, and altered surface winds. This phenomenon could be part of human-induced climate change, according to researchers.
A CU study of ice-age sediment cores found that temperature fluctuations in the warm Atlantic Ocean were as large as those seen during the last ice age, raising concerns about future climate change. The research suggests that human-induced changes to ocean circulation could trigger global climate impacts.
Researchers have assembled 20 articles to study interactions at the Antarctic Continental Margin, presenting new techniques and expanding year-round measurements. The volume includes a bathymetric chart of the southern Weddell Sea, providing insights into longer-term cycles.
Researchers at the University of Illinois found a correlation between Pacific Ocean sea-surface temperatures and precipitation rates in the Great Plains. Warmer ocean temperatures lead to increased storm activity, resulting in wetter weather.
Global climate factors point to more active storm era, with warmer sea surface temperatures and increased rainfall in the Sahel region. This trend contrasts with the most inactive four-year stretch within the same period, from 1991-94.
Research suggests that ocean heat transport, rather than Milankovitch cycles, is driving the cooling trend in Greenland's climate. The thermometers from the Greenland ice cores indicate that summers have cooled and winters have warmed over the past 8,000 years.
New research suggests that the Pacific Ocean's natural air-ocean circulation system may be counteracting global warming by redistributing heat. The study, conducted by Lamont-Doherty scientists, found that surface waters in the eastern equatorial Pacific have cooled over the past century despite rising Earth temperatures.
