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 …
By failing to account for the effects of climate change, long-term projections of extreme weather are providing dangerously inaccurate guidance for critical investments in infrastructure and public safety.
Tuna boats in the eastern Atlantic and Mediterranean will be alowed to catch a total of 13,500 tonnes of bluefin tuna next year, down from the provisional quota of 19,950 tonnes. The International Commission for the Conservation of Atlantic Tunas (ICCAT) says this gives the species a 60 per cent …
230Th-dated oxygen isotope records of stalagmites from SanbaoCave, China, characterize Asian Monsoon (AM) precipitation throughthe ends of the third- and fourthmost recent ice ages. As aresult, AM records for the past four glacial terminations cannow be precisely correlated with those from ice cores and marinesediments, establishing the timing and sequence …
This article investigates weaknesses of consumer boycotts. First, usual shortcomings of collective action, such as coordination failure and free riding, reduce considerably the success likelihood. Second, consumers with the highest ability to hurt the targeted firm
Atlantic tropical cyclone activity, as measured by annual storm counts, reached anomalous levels over the past decade. The short nature of the historical record and potential issues with its reliability in earlier decades, however, has prompted an ongoing debate regarding the reality and significance of the recent rise. Here the …
Without drastic cuts in emissions, the Transpolar Drift, one of the Arctic's most powerful currents and a key disperser of pollutants, is likely to disappear because of global warming.
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 …
evolution Link...or is it? A well-preserved fossil of primitive lemur Darwinius masilla, nicknamed Ida is believed to represent the point from which the group of monkeys, apes and humans (anthropoids) evolved. The fossil lacks the traits which characterize a modern lemur, a non-human primate. Instead it has a bone in …
Das et al.1 have studied clay mineralogy, terrigenous and biogenic components of the sediment core collected from the Ocean Drilling Programme site 728A, northwestern continental margin of the Arabian Sea, off Oman. Their main objectives were to understand palaeoclimatic conditions, such as monsoons fluctuations, weathering processes and transport pathways of …
New York, Boston and other cities on North America's northeast coast could face a rise in sea level this century that would exceed forecasts for the rest of the planet if Greenland's ice sheet keeps melting as fast as it is now, researchers said on Wednesday. Sea levels off the …
Mathematical modelling and time series analysis techniques are important tools for extracting information from complex geotime series. These techniques also facilitate a fair degree of prediction, which is one of the prime goals of science. The data analysis strategy for such a purpose mainly involves spectral analysis and pattern classification. …
A $500 million North Atlantic shrimp fishery may be vulnerable to climate change that could disrupt the crustaceans' life cycle and mislead them into hatching when food is scarce, scientists said. Any damage to stocks of the northern shrimp -- a small, sweet-tasting variety popular in salads -- could have …
India's monsoon rains, vital for the farm-dependent economy and the success of major crops, may exceed the norm this year if the El Nino system that brings drier weather fails to appear, as expected, forecasters say. That would be good news for a country hit by the global recession, ensuring …
Overfishing will wipe out the breeding population of Atlantic bluefin tuna, one of the ocean's largest and fastest predators, in three years unless catches are dramatically reduced, conservation group WWF said on Tuesday. As European fishing fleets prepare to begin the two-month Mediterranean fishing season on Wednesday, WWF said its …
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.
The asynchronous relationship between millennial-scale temperature changes over Greenland and Antarctica during the last glacial period has led to the notion of a bipolar seesaw which acts to redistribute heat depending on the state of meridional overturning circulation within the Atlantic Ocean. Here we present new records from the South …
The Atlantic meridional overturning circulation (AMOC) transports warm salty surface waters to high latitudes, where they cool, sink and return southwards at depth. Through its attendant meridional heat transport, the AMOC helps maintain a warm northwestern European climate, and acts as a control on the global climate. Past climate fluctuations …
