Thwaites Glacier won't collapse like dominoes as feared, but it doesn't mean the 'Doomsday Glacier' is stable

Antarctica's Thwaites Glacier got its nickname the "Doomsday Glacier" for its potential to flood coastlines around the world if it collapsed. It is already contributing about 4% of annual sea-level rise as it loses ice, and one theory suggests the glacier could soon begin to collapse into the ocean like a row of dominoes.
