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 …
Since the beginning of the Industrial Revolution humans have released ~500 billion metric tons of carbon to the atmosphere through fossil-fuel burning, cement production and land-use changes. About 30% has been taken up by the oceans. The oceanic uptake of carbon dioxide leads to changes in marine carbonate chemistry resulting …
New research from the University of Missouri indicates that Atlantic Ocean temperatures during the greenhouse climate of the Late Cretaceous Epoch were influenced by circulation in the deep ocean. These changes in circulation patterns 70 million years ago could help scientists understand the consequences of modern increases in greenhouse gases. …
BE IT plant or animal, introduction of a foreign species to an environment has more often than not put the native ones at risk. At places, while competing for food and space, foreign species become so invasive that they push the region’s predominant organisms to extinction. In case of animals, …
Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variations in …
Dust is all that's needed to plunge the world into an ice age. When blown into the sea, the iron it contains can fertilise plankton growth on a scale large enough to cause global temperatures to drop. The finding adds support to the idea of staving off climate change by …
The first decade of the 21st century was the hottest since the beginning of the Industrial Revolution. Global warming is real and, if present trends continue, its possible effects worry publics and governments around the world. Could it foster armed conflict for resources such as food and water? Will Western …
The Atlantic Ocean receives warm, saline water from the Indo-Pacific Ocean through Agulhas leakage around the southern tip of Africa. Recent findings suggest that Agulhas leakage is a crucial component of the climate system and that ongoing increases in leakage under anthropogenic warming could strengthen the Atlantic overturning circulation at …
The Arctic is responding more rapidly to global warming than most other areas on our planet. Northward-flowing Atlantic Water is the major means of heat advection toward the Arctic and strongly affects the sea ice distribution. Records of its natural variability are critical for the understanding of feedback mechanisms and …
The meridional overturning circulation (MOC) of the Atlantic Ocean is considered to be one of the most important components of the climate system. This is because its warm surface currents, such as the Gulf Stream, redistribute huge amounts of energy from tropical to high latitudes and influence regional weather and …
European nations agreed on Friday to set up fishing-free zones in remote parts of the Atlantic Ocean in the world's first high seas network of protected areas beyond the control of national governments. Environment ministers from 15 European states, forming the OSPAR group overseeing the North-East Atlantic, said they would …
Efforts to clean up and protect the North East Atlantic have made some progress since 2000 but new threats are looming such as ocean acidification linked to climate change, a study said on Thursday. The report, by the OSPAR Commission that groups 15 European nations and covers an area from …
Climate change is often associated with an increase in the frequency of extreme weather events, such as heat waves or intense precipitation. Here, however, downscaled climate model simulations have been used to show that the frequency of North Atlantic polar lows
In the oceans, ubiquitous microscopic phototrophs (phytoplankton) account for approximately half the production of organic matter on Earth. Analyses of satellite-derived phytoplankton concentration (available since 1979) have suggested decadal-scale fluctuations linked to climate forcing, but the length of this record is insufficient to resolve longer-term trends. Here we combine available …
The deuterium excess of polar ice cores documents past changes in evaporation conditions and moisture origin. New data obtained from the European Project for Ice Coring in Antarctica Dome C East Antarctic ice core provide new insights on the sequence of events involved in Termination II, the transition between the …
Fishing down the food chain is a controversial issue that demands further exploration. Redfeed is a marine species located on the second to last level on the food web. It is also one of the potential saviors of the aquaculture industry. The role of effective management of this species is …
Although recent studies suggest that climate change may substantially accelerate the rate of species loss in the biosphere, only a few studies have focused on the potential consequences of a spatial reorganization of biodiversity with global warming. Here, we show a pronounced latitudinal increase in phytoplanktonic and zooplanktonic biodiversity in …
Our current concepts of abrupt climate change are strongly influenced by compelling palaeoclimate evidence for events like the Younger Dryas, in which massive changes in climate occurred essentially instantaneously. It is generally thought that an injection of freshwater from the retreating Laurentide Ice Sheet altered the Atlantic Meridional Overturning Circulation …
A thousand years after the last ice age ended, the Northern Hemisphere was plunged back into glacial conditions. For 20 years, scientists have blamed a vast flood of meltwater for causing this
How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data …
