Indian Ocean may be key to global warming 'hiatus'. Upper ocean may be storing heat, giving atmosphere a break.
The Indian Ocean may be the dark horse in the quest to explain the puzzling pause in global warming, researchers report on 18 May in Nature Geoscience1. The study finds that the Indian Ocean may hold more than 70% of all heat absorbed by the upper ocean in the past decade.
Scientists have long suspected that oceans have played a crucial role in the so-called warming hiatus by storing heat trapped in the atmosphere by rising levels of greenhouse gases. But pinpointing exactly which ocean acts as a global air conditioner has proved challenging.
