Indian Ocean Dipole- New phenomenon to emerge

  When the Indian Ocean’s ancient climate patterns return About 19,000-21,000 years ago, ice-sheets covered North America and Eurasia, and sea-levels were much lower, with Adam’s Bridge exposed so that the Indian subcontinent and Sri Lanka were contiguous. This period, the peak of ice age conditions, is called the Last Glacial Maximum. Researchers analysed simulations of this past climate and predicted that the ongoing climate change could reawaken an ancient clim

Sea Level Rise: Its impact

Sea Level Rise: Its impact GS-PAPER-1 Geography: Oceanography (PT-MAINS) Recently, a study in journal Scientific reports made predictions that a large population and assets will be globally affected as a consequence of Sea Level Rise (SLR).
