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 …
More than half a dozen oceanographic buoys are missing in action in the eastern Pacific Ocean. The US National Oceanic and Atmospheric Administration (NOAA) has dispatched a ship to fix the malfunctioning buoys, which are part of the 55-strong Tropical Atmosphere Ocean (TAO) array that monitors the ocean and atmosphere.
In a major step towards boosting India's capabilities to study oceanography, the Polar Satellite Launch Vehicle (PSLV), the time-tested workhorse of Indian Space Research Organisation (ISRO), is all set to place the 960 kg satellite, Oceansat-2, in a sun-synchronous orbit tomorrow. This will be India's 16th space mission from the …
food security Ethiopia defends land grab Ethiopia, where 20 per cent of the people are in urgent need of food aid, defended its plan to offer 2.7 million hectares (ha) cultivable land to foreign companies.
Warming decreases low-level cloud cover, contributes to its own increase WHEN the oceans warm, water evaporates and cloud cover increases. This is the well known science behind cloud formation. A new study begs to differ. Of the three major kinds
Temperature reconstructions for the surface of the Northern Hemisphere are based largely on terrestrial records from extra-tropical or high-elevation sites, despite the fact that global average surface temperature changes closely follow those of the global tropics, which are 75 per cent ocean. Here, a decadally resolved continuous sea surface temperature …
Washington: Environmentalists have long denounced plastic as a pollutant that does not break down. A new study indicates that in the oceans, plastic does decompose with surprising speed, but says that is not a good thing either. Thousands of tons of plastic debris wind up in the oceans every year, …
The low 13C/12C ratio in some Neoproterozoic carbonates is considered to be evidence of carbon cycle perturbations unique to the Precambrian. Here, all published oxygen and carbon isotope data for Neoproterozoic marine carbonates are compiled. The combined isotope systematics are found to be identical to those of well-understood Phanerozoic examples, …
Climate change disrupts ecological systems in many ways. Many documented responses depend on species' life histories, contributing to the view that climate change effects are important but difficult to characterize generally. However, systematic variation in metabolic effects of temperature across trophic levels suggests that warming may lead to predictable shifts …
Mumbai: As rains lashed the city, the metropolis is all set to face the highest tide of the season which will hit its shores today. The meteorological department had allayed fears of large scale flooding due to rains and said that it was unlikely very heavy rains would be experienced …
Bids For Patent On System For Lowering Ocean Temperatures To Slow Down Storms Tony Allen-Mills Bill Gates, the co-founder of Microsoft, is backing inventors and climate scientists who claim to have devised a technique for diminishing the power of hurricanes. Gates was named last week among a group of weather …
Ice cores extracted from the Antarctic ice sheet suggest that glacial conditions and the relationship between temperatures and atmospheric carbon dioxide concentrations have been constant over the last 800,000 years, but there is some evidence for a fluctuating severity of glacial periods mediated by previously unidentified mechanisms. Variable migration of …
The presence of ice-rafted debris (IRD) in middle Eocene ocean sediments has previously been demonstrated, but it has been unclear whether the source of IRD was land-based glacial ice or sea ice, a distinction with important climate implications. The analysis of a sediment core from the ACEX project now reveals …
At times in the past, mobile ocean fronts in the subtropics have exercised an influence on the magnitude of climate change by decoupling temperature from levels of carbon dioxide in the atmosphere.
