Japanese researchers have indicated the possibility of La Nina, the alter ego of monsoon-buster El Nino, to unfold over the equatorial Pacific later this year.
La Nina, which represents shift of warmer sea-surface temperatures to the west equatorial Pacific, has generally coincided with a normal Indian monsoon, though there is no direct cause-effect relationship.
For Indian Space Research Organisation (ISRO) the rare and longest solar eclipse on Friday is going to be crucial to study the atmospheric changes and its consequences before, during and after the eclipse.
Ranchi, Jan. 10: Scientists of Birla Institute of Technology (BIT), Mesra, are getting ready to witness the solar eclipse that will occur on January 15, a day after Makar Sankranti.
2009 was tied for the second warmest year in the modern record, a new NASA analysis of global surface temperature shows. The analysis, conducted by the Goddard Institute for Space Studies (GISS) in New York City, also shows that in the Southern Hemisphere, 2009 was the warmest year since modern records began in 1880.

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 the Antarctica were increased by six degrees Celsius during the past periods when the volume of high carbon dioxide (CO2) was high in the atmosphere.
