Rising sea temperatures are pushing Great Barrier Reef to brink
Rising sea temperatures are causing increasing signs of stress and threatening the existence of one of the world’s most diverse and valuable marine ecosystems, Australia’s Great Barrier Reef, according to a new international study from a team of researchers that…
Greenland’s ice shelves have lost more than a third of their volume
The largest floating ice shelves in the polar ice sheet have lost more than a third of their volume since 1978.
Researchers find Antarctic ice shelves thinner than previously thought
As global ice dams begin to weaken due to warming temperatures, a new study suggests that prior attempts to evaluate the mass of the huge floating ice shelves that line the Antarctic ice sheet may have overestimated their thickness.
Using Evidence From Last Ice Age, Scientists Predict Effects of Rising Seas on Coastal Habitats
The rapid sea level rise and resulting retreat of coastal habitat seen at the end of the last Ice Age could repeat itself if global average temperatures rise beyond certain levels, according to an analysis by an international team of scientists from more than a dozen institutions, including Rutgers.
Modeling ocean to understand natural phenomena
Associate Professor Yoshi N. Sasaki, a specialist in Physical Oceanography, is involved in research into rising sea levels—particularly in coastal areas of Japan. He spoke about what he has learned so far about the relationship between ocean currents, sea level and climate change, what research he is currently focusing on, and the appeal of research that uses numerical modeling to uncover natural phenomena.
Expert available to discuss new report that puts globe on course for breaching benchmark high temperature
A new report from the World Meteorological Organization (WMO) shows that the world’s average temperature could breach a record 1.5 Celsius of warming compared to pre-Industrial Revolution levels. News reports call the WMO announcement a critical warning of an average world temperature limit in the face of climate. Researchers indicate the threshold could be broken as early as 2027.
Study Illustrates Nuances of Gravitational Pull of Ice Sheets
When a large ice sheet begins to melt, global-mean sea level rises, but local sea level near the ice sheet may in fact drop. In American Journal of Physics, a researcher illustrates this effect through a series of calculations, beginning with a simple, analytically tractable model and progressing through more sophisticated mathematical estimations of ice distributions and gravitation of displaced seawater mass. The paper includes numerical results for sea level change resulting from a 1,000-gigatonne loss of ice, with parameter values appropriate to the Greenland and Antarctic ice sheets.
Chula Engineering Cures Salty Tap Water with NanoTech
During the dry season this year, Bangkok residents have faced the saltiest tap water problem in 20 years as a result of global warming and seawater rise. Chulalongkorn engineers predict the problem to persist until May and have proposed solutions with desalination technology.
Increasing ocean temperature threatens Greenland’s ice sheet
Irvine, Calif., Jan. 25, 2021 — Scientists at the University of California, Irvine and NASA’s Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland’s fjords. Their work is the subject of a study published recently in Science Advances. Working under the auspices of the Oceans Melting Greenland mission for the past five years, the researchers used ships and aircraft to survey 226 glaciers in all sectors of one of Earth’s largest islands.
East Antarctica’s Denman Glacier has retreated almost 3 miles over last 22 years
Irvine, Calif., March 23, 2020 – East Antarctica’s Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.
Greenland shed ice at unprecedented rate in 2019; Antarctica continues to lose mass
Irvine, Calif., March 18, 2020 – During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tons of ice, enough to raise global sea levels by 2.2 millimeters in two months. On the opposite pole, Antarctica continued to lose mass in the Amundsen Sea Embayment and Antarctic Peninsula but saw some relief in the form of increased snowfall in Queen Maud Land, in the eastern part of the continent.
Tulane scientist embarks on mission to Florida-sized glacier
Geologist Brent Goehring is joining researchers from across the U.S. and the U.K. to research sea-level rise
Reframing Antarctica’s Meltwater Pond Dangers to Ice Shelves and Sea Level
Meltwater ponds riddle a kilometer-thick ice shelf, which then shatters in just weeks, shocking scientists and speeding the flow of the glacier behind it into the ocean to drive up sea level. A new study puts damage by meltwater ponds to ice shelves and sea level into cool, mathematical perspective.
