The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
BALASORE: Launch of an ocean satellite is the next mission of Indian Space Research Organisation (ISRO) after the successful launch of Chandrayaan-1, said G Madhavan Nair, ISRO chairman and Secretary of the Department of Space. Nair who was here recently to attend the fifth convocation of Fakir Mohan University told …
This report addresses some of the major questions facing climate change researchers, and how those puzzles are being addressed by NSF-funded activities. Complex computer models are being developed and refined to predict Earth
The global oceans community is very thankful to the Government of Indonesia for hosting the World Ocean Conference 2009 to put the limelight on the relationship between climate change and oceans, coasts, and small island developing States (SIDS). The political consensus that will be reached by governmental representatives in issuing …
THIRUVANANTHAPURAM: Agriculture scientist M.S. Swaminathan said here on Saturday that the State government or Kerala Agriculture University should take steps to establish a research and training centre on below sea-level farming at Kuttanad. Speaking on
Sekisei Lagoon: Beneath the waves of this sapphire-blue corner of the East China Sea, a team of divers was busily at work. Hovering along the steep face of a coral reef, some divers bored holes into the surface with compressedair drills that released plumes of glittering bubbles. Others followed, gently …
After a controversial projection that wild caught fish will disappear, top researchers buried the Dhatchet to examine the status of fisheries-and what to do about it.
A decrease in atmospheric methane levels might have triggered the progressive rise of atmospheric oxygen about 2.4 billion years ago, but the cause of this methane decrease remains uncertain. Kurt Konhauser and colleagues report a decline in the oceanic nickel-to-iron ratio about 2.7 billion years ago, which they attribute to …
Some Scientific Models Go A Step Further, Predict Large Portion Of Ice Could Disappear In 11 Years Washington: Some 80% of Arctic ice may disappear in 30 years, not 90 as scientists had previously estimated, according to a new study on the impact of global warming.
The U.S. Environmental Protection Agency can compare costs with benefits to determine the technology that must be used at power plant water-cooling structures, the Supreme Court ruled on Wednesday in a setback for those seeking greater protection for aquatic life. By a 6-3 vote, the high court handed a victory …
Marine litter is a global concern affecting all the oceans of the world. It poses environmental, economic, health and aesthetic problems that are rooted in poor solid waste management practices, lack of infrastructure, indiscriminate human activities and behaviours and an inadequate understanding on the part of the public of the …
The Pliocene warm interval has been difficult to explain. We reconstructed the latitudinal distribution of sea surface temperature around 4 million years ago, during the early Pliocene. Our reconstruction shows that the meridional temperature gradient between the equator and subtropics was greatly reduced, implying a vast poleward expansion of the …
FOR MUTUAL SUPPORT: Vice-Admiral Vijay Shankar handing over a memento to Vice-Chancellor G. Thiruvasagam during a visit to Bharathiar University in Coimbatore on Friday. COIMBATORE: Vice-Admiral Vijay Shankar, Commander-in-Chief, Andaman and Nicobar Command, has expressed his interest in developing ocean resource mining through satellite remote sensing for better utilisation of …
Fish can do it by producing and excreting carbonates THE marine carbon cycle is undergoing rapid changes. An excess of unregulated carbon will eventually acidify the oceans. A new study demonstrates that fish have the potential to save the marine carbon cycle. Until now scientists believed that the calcium carbonate …
Scientists propose burying it below oceans WORLD carbon dioxide levels are rising. The future is expected to be exceptionally warm. Many technologies are being proposed to tackle it. Efficiently reducing global warming requires carbon capture in large amounts. Furthermore, the captured carbon has to stay that way for thousands of …
A model analysis of the uptake of carbon dioxide in the North Atlantic carries with it a cautionary reminder about interpreting what may be short-term trends as signals of long-term climate change.
Ocean temperature is one of the primary environmental factors that determine the geographic range of a species. A paper published recently in the journal Fish and Fisheries has used computer modelling to project the global impact of climate change on biodiversity with reference to 1,000-odd fish species. The study has …
Geoscientists claim to have discovered an entire ocean that was destroyed 20 to 50 million years ago when its sea floor sank some 1,100km into the earth between Australia and New Zealand. An international team has reconstructed the cataclysm which took place when the tectonic plate underlying the ocean
