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 …
A new analysis of ice cores conducted by scientists of National Center for Atmospheric Research (NCAR) and the University of Washington (UW) show the existence of connection of the world's coldest continent Antarctica to global warming, as well as to periodic events such as El Ni
Dead zones in the coastal oceans have spread exponentially since the 1960s and have serious consequences for ecosystem functioning. The formation of dead zones has been exacerbated by the increase in primary production and consequent worldwide coastal eutrophication fueled by riverine runoff of fertilizers and the burning of fossil fuels. …
Ozeaneum, an ambitious oceanography museum opened its doors to the public in the north-eastern German port town of Stralsund on July 12. It contains 39 huge fish tanks and seven life-size models of whales. Ozeaneum is an architecturally dramatic extension to the existing Oceanography Museum in Stralsund, a town on …
The onset of major glaciations in the Northern Hemisphere about 2.7 million years ago was most probably induced by climate cooling during the late Pliocene epoch. These glaciations, during which the Northern Hemisphere ice sheets successively expanded and retreated, are superimposed on this long-term climate trend, and have been linked …
SYDNEY: Elephant seals swimming under Antarctic ice and fitted with special sensors are providing scientists with crucial data on ice formation, ocean currents and climate change, a study released on Tuesday said. The seals swimming under winter sea ice have overcome a
The main mandate of National Institute of Oceanography is to develop knowledge on physical, chemical, biological, geological, geophysical, engineering and pollution aspects of the waters around India.
Oceanic anoxic events (OAEs) were episodes of widespread marine anoxia during which large amounts of organic carbon were buried on the ocean floor under oxygen-deficient bottom waters. OAE2, occurring at the Cenomanian/Turonian boundary (about 93.5 Myr ago), is the most widespread and best defined OAE of the mid-Cretaceous. Although the …
From the timing, it looks as if an episode of marked oceanic oxygen deficiency during the Cretaceous was the result of undersea volcanism. Studies of such events are relevant to the warming world of today.
Abrupt drop in temperatures in 1940s, how accurate? LET"s hear it from sailors of the 1940s. One group collected sea water in buckets and measured the temperature of sea water; the other group measured the temperature of water used for cooling engines. Often, the temperature from buckets was lower since …
acidic oceans: Dissolved CO2 makes water more acidic. UK researchers saw a fall in the species numbers and snails with their shells disintegrating in vents in the Mediterranean sea. They say impacts such as changing of marine food web and decrease in biodiversity might become common with the increase of …
Much of the scientific and public focus on anthropogenic carbon dioxide emissions have been on climate impacts. Emission targets have been suggested based primarily on arguments for preventing climate from shifting significantly from its preindustrial state. However, recent studies underline a second major impact of carbon emissions: ocean acidification. Over …
Here the authors show the effects of acidification on benthic ecosystems at shallow coastal sites where volcanic CO2 vents lower the pH of the water column. Along gradients of normal pH (8.1
Rising levels of atmospheric carbon dioxide lead to acidification of the oceans. A site in the Mediterranean, naturally carbonated by under-sea volcanoes, provides clues to the possible effects on marine ecosystems.
weight matters: Obesity contributes to global warming, says a study. Obese people require 1,680 daily calories to sustain normal energy and another 1,280 calories to maintain daily activities. This is 18 per cent more than someone with a stable body mass index. The next step will be to quantify how …
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 …
Halogens are known to decrease the levels of stratospheric ozone. The latest measurements show that something similar occurs in the lower atmosphere over tropical oceans
TIMES VIEW Store it but after proper testing The proposal to store carbon dioxide in the depths of some of the world's deepest oceans is not a slapdash solution put together by myopic scientists as some environmentalists would have us believe. Instead the concept is the creation of concerned climatologists …
A French-US satellite, which will provide the most accurate monitoring ever of rising sea levels and track the effects of climate change, was launched into orbit on Friday from a California base. A rocket carrying the Jason 2 satellite took off from Vandenberg Air Force base. Jason 2 is a …
The World's oceans have warmed 50 per cent faster over the last 40 years than previously thought due to climate change,Australian and US climate researchers have reported Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening …
