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 …
Jessica Aldred and Ian Sample London: More than a quarter of sharks and rays in the northeast Atlantic face extinction through the effects of over fishing, with 7 per cent classed as critically endangered, conservationists have warned. The Red List published by the International Union for Conservation of Nature says …
A quarter of sharks and rays are threatened with being fished out of existence in the Northeast Atlantic, the International Union for Conservation of Nature (IUCN) said on Monday. That is far above the threat level globally, reflecting the activity of fishing nations such as Spain, Portugal, France and Britain, …
A key question in the study of near term climate change is whether there is a causal connection between warming tropical sea surface temperatures (SSTs) and Atlantic hurricane activity. Such a connection would imply that the marked increase in Atlantic hurricane activity since the early 1990s is a harbinger of …
Reconstructions of ancient atmospheric carbon dioxide (CO2) variations help us better understand how the global carbon cycle and climate are linked. We compared CO2 variations on millennial time scales between 20,000 and 90,000 years ago with an Antarctic temperature proxy and records of abrupt climate change in the Northern Hemisphere. …
About 350 to 400 North Atlantic right whales exist today. The survivors migrate along North America's East Coast between feeding grounds in the Gulf of Maine and wintering sites farther south
Atlantic tropical cyclones are getting stronger on average, with a 30-year trend that has been related to an increase in ocean temperatures over the Atlantic Ocean and elsewhere. Over the rest of the tropics, however, possible trends in tropical cyclone intensity are less obvious, owing to the unreliability and incompleteness …
The theory that global warming may be contributing to stronger hurricanes in the Atlantic over the past 30 years is bolstered by a new study led by a Florida State University researcher. The study is published in the Sept. 4 edition of the journal Nature. Using global satellite data, FSU …
The Saharan duststorms help sustain life over large regions of the North Atlantic Ocean, according to a latest study. Liverpool University researchers found that plants are able to grow in these regions because of their ability to take advantage of iron minerals in Saharan duststorms. This allows them to use …
Increasing tropospheric ozone levels over the past 150 years have led to a significant climate perturbation; the prediction of future trends in tropospheric ozone will require a full understanding of both its precursor emissions and its destruction processes. A large proportion of tropospheric ozone loss occurs in the tropical marine …
The dust that originates in the Sahara Desert, is lofted by windstorms which carries it west over the Atlantic. High levels of airborne dust reduce the amount of sunlight that reaches the ocean, lowering sea surface temperatures and, generally, hurricane probability. Researchers in the Cooperative Institute for Meteorological Satellite Studies …
even though the earth is heating up there could be some relief, say recent studies. And we have to thank the Atlantic Ocean for this respite. Researchers at Leibniz Institute of Marine Sciences, Kiel, Germany, who studied the Atlantic say the ocean's natural phenomenon could slow down global warming. The …
While studies indicate that global temperatures may not increase over the next decade, there is no respite for the Arctic sea ice, this year at least. There are very high chances, about 60 per cent, that the ice may shrink below the record minimum seen last year, says a press …
In 2005, southwestern Amazonia experienced the effects of an intense drought that affected life and biodiversity. Several major tributaries as well as parts of the main river itself contained only a fraction of their normal volumes of water, and lakes were drying up. Analyses of climatic and hydrological records in …
A major modelling study forecast that warming of the north Atlantic could make hurricanes scarcer - while the worst ones might have stronger winds and produce more rain. Thomas Knutson and colleagues from NASA's Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey, have previously produced a remarkably accurate year-by-year "hindcast" …
The climate of the North Atlantic region exhibits fluctuations on decadal timescales that have large societal consequences. Prominent examples include hurricane activity in the Atlantic, and surface-temperature and rainfall variations over North America, Europe and northern Africa. Although these multidecadal variations are potentially predictable if the current state of the …
The effects of global warming over the coming decades will be modified by shorter-term climate variability. Finding ways to incorporate these variations will give us a better grip on what kind of climate change to expect.
Studies suggest that tropical cyclones are becoming more powerful with the most dramatic increase in the North Atlantic. The increase is correlated with an increase in ocean temperature. A debate concerns the nature of these increases with some studies attributing them to natural climate fluctuations, and others suggesting climate change …
Attaching a 'floating' tree-ring chronology to ice core records that cover the abrupt Younger Dryas cold interval during the last glacial termination provides a better estimate of the onset and duration of the radiocarbon anomaly. The chronology suggests that marine records may be biased by changes in the concentration of …
Because of difficulties in creating a radiocarbon calibration that covers the end of the last glaciation, defining the timing and duration of the Younger Dryas cold event has been a challenge. Linking related cosmogenic isotopes in tree rings and ice cores may provide new insights into abrupt climate changes.
