This is the 33rd issuance of the annual assessment now known as State of the Climate, published in the Bulletin since 1996. As a supplement to the Bulletin, its foremost function is to document the status and trajectory of many components of the climate system. However, as a series, the …
The Southern Ocean is potentially a substantial sink of anthropogenic carbon dioxide; however, the regulation of this carbon sink by the wind-driven Ekman flow, mesoscale eddies and their interaction is under debate. Here, a high-resolution ocean circulation and carbon cycle model is used to study intra-annual variability in anthropogenic carbon …
London: Over 40,000 eco-tourists visiting Antarctica every year are adding to global warming that results in melting of the polar ice caps, a new research has found. Most of these tourists to the snow-covered South Pole travel in cruise ships to view the ice caps and wildlife causing
Sea levels during the last interglacial stage (about 125 kyr ago) are known to have been higher than today, and may serve as a partial analogue for anthropogenic warming scenarios. However, because local sea levels differ from global sea level, accurately reconstructing past global sea level requires an integrated analysis …
Coastal cities and islands all across the world, including India, are facing serious threat from thinning of ice in Antarctica, according to latest research by 100 world-leading scientists from eight countries released here on Wednesday. The Scientific Committee on Antarctic Research, in the first comprehensive review of the state of …
RASHME SEHGAL India's coastal cities are under a new threat. The rapid melting of Antarctica ice will see sea levels rise by over one metre international scientists warn. The first comprehensive review of the state of Antarctica's climate and its relationship to the global climate system released by the Scientific …
Antarctica Glaciers Study Sounds Alarm TIMES NEWS NETWORK Days before the Copenhagen conference on climate change kicks off, a major study by a group of 100 international scientists has said that sea levels are likely to rise by as much as 1.4 metres (more than 4 feet) by the end …
A comprehensive, up-to-date account of how the physical and biological environment of the Antarctic continent and Southern Ocean has changed from Deep Time until the present day. Also considers how the Antarctic environment may change over the next century in a world where greenhouse gas concentrations are much higher than …
A cluster of Antarctic icebergs were heading towards New Zealand after being spotted around 400 kilometres south of the country, scientists said on Friday. Icebergs are a rare sight in the sub-Antarctic waters south of New Zealand but in 2006 a number floated to within 25 kilometres of the coastline, …
If the world fails to get the growing carbon emission under control, sea levels could rise by up to six metres, said a new study. According to the study by the British Antarctic Survey (BAS), temperatures in Antarctica were increased by six degrees Celsius during the past periods when the …
Reconstructions of temperature variations from Antarctic ice cores rely on the assumption that the relationship between hydrogen and oxygen isotope ratios and temperature are stable in space and time. Three East Antarctic ice core records are now analysed alongside input from general circulation models to reveal that during warmer interglacial …
In what can be seen as a positive impact of global warming, large blooms of tiny marine plants called phytoplankton that can absorb carbon dioxide from atmosphere are flourishing in the area opened up by massive ice melting in Antarctica. Without ice cover, the water get exposed to light and …
Analyses of boron isotopes in ancient marine carbonate sediments provide an enlightening perspective on the links between carbon dioxide and ice-cap cover at a climatically momentous time in Earth's history.
Mass loss from the glaciers along the margins of the Greenland and Antarctic ice sheets is increasingly contributing to sea level rise. However, ice loss as a result of accelerated flow, known as dynamic thinning, is so poorly understood that its potential future contribution to sea level remains unpredictable. Here, …
About 34 million years ago, the first major Antarctic ice sheets appeared, suggesting that major cooling had taken place; however, the global transition into this icehouse climate remains poorly constrained. A new, continuous record of sea surface temperature (SST) from an ocean sediment core in the East Tasman Plateau now …
