New Delhi: Ending days of suspense and anxiety for the Indo-German team of scientists sailing in the cold and desolate waters off Antarctica, the German government on Monday gave the go-ahead to a controversial ocean-seeding experiment that experts say could lead to a way of fighting global warming.
Washington: Antarctica, the only place that had oddly seemed immune from climate change, is warming after all, according to a new study. For years, Antarctica was an enigma to scientists who track the effects of global warming. Temperatures on much of the continent at the bottom of the world were staying the same or slightly cooling, previous research indicated.
Assessments of Antarctic temperature change have emphasized the contrast between strong warming of the Antarctic Peninsula and slight cooling of the Antarctic continental interior in recent decades1. This pattern of temperature change has been attributed to the increased strength of the circumpolar westerlies, largely in response to changes in stratospheric ozone2.
ROTHERA BASE - Renewable energies are gaining a foothold in Antarctica, curbing fossil fuel use despite problems in designing installations to survive bone-chilling cold and winter darkness.
The last and third 50-member team of scientists in the 28th Indian Scientific Expedition to Antarctica was flagged here today.
The successive Antarctica expeditions are in continuation of India's efforts at studying various aspects of climate variability, besides unlocking the secrets of life in the sub-zero temperatures.

Antarctic sediments dating from 30 million to 145 million years ago (a time during which the vast Antarctic ice sheet is thought to have formed and the Transantarctic mountains pushed up) have been a valuable source of information about the forces that changed the climatic conditions of the Antarctic continent.
WASHINGTON: More than two trillion tonnes of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming.
