A new study has thrown up some alarming facts about the effects of climate change. A study published in the journal Nature says, as atmospheric warming continues to rise, 60 percent of the ice shelves in Antarctica are at risk of fracture. The study adds that this would in turn accelerate the loss of ice sheets and increase sea levels drastically, putting those living in coastal areas at major risk. Antarctic ice shelves are useful in preventing the flow of ice into the oceans but if they get fractured, ice flow will get accelerated, as per the study. The study cautions that a lot of climate models do not include the impact of this 'hydrofracturing' process. Researchers say the next step, however, is to determine how much and how fast this hydrofracturing will occur.
