"Antarctic Ice Melt Accelerates: New Zealand Expedition Uncovers Alarming Signs"

A team of New Zealand and Italian scientists returned from a two-month expedition in Antarctica's Ross Sea, reporting worrying evidence of rapidly melting ice and substantial changes in the Southern Ocean. They found dramatic decreases in ice coverage, record lows in surrounding ice, and shifts in the amount of salty and oxygenated water reaching deeper ocean areas. The implications include coastal city reconfigurations due to rising sea levels, impacts on marine ecosystems and weather systems, and the urgent need for further research to inform forecasting models and government planning.

Antarctic ice melt threatens global ocean currents.

Rapidly melting Antarctic ice is causing a dramatic slowdown in the flow of water through the world's oceans, which could have disastrous impacts on global climate, the marine food chain, and even the stability of ice shelves. The deep ocean water flows from the Antarctic could decline by 40% by 2050, reducing the salinity and density of the surface water and diminishing the downward flow to the sea's bottom. This effect has not yet been included in the complex models used by the IPCC to describe future climate change scenarios, but it is going to be considerable.

Antarctic ice melt threatens global ocean currents.

Rapidly melting Antarctic ice is causing a dramatic slowdown in the flow of water through the world's oceans, which could have a disastrous impact on global climate, the marine food chain, and even the stability of ice shelves. The deep ocean water flows from the Antarctic could decline by 40% by 2050, according to a study published in the journal Nature. The effect of meltwater on global ocean circulation has not yet been included in the complex models used by the IPCC to describe future climate change scenarios, but it is going to be considerable.
