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.
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 of globally distributed data sets.
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.
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.
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 occurred over the last few centuries.
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, the first such sighting since 1931.
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 volume of high carbon dioxide (CO2) was high in the atmosphere.
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.
