This one Antarctic1 glacier2 is the size of the UK and is already responsible for five percent of world sea level rise. And the rate the Thwaites Glacier is melting has accelerated3 fivefold in the last 30 years.
 
这个南极冰川的面积相当于英国的面积,它已经造成了全球海平面上升5%。在过去的30年里,思韦茨冰川的融化速度加快了五倍。
 
Last year, a team of British and American scientists set up camp on the glacier. It is one of the most remote places on Earth.
 
By measuring the gravitational pull of the seabed under the ice, they discovered a network of deep channels, a key step in understanding why the glacier is changing so rapidly.
 
This is what they think is happening. A series of huge channels - some almost a kilometre below the ice - allow the warmer, deep ocean water to flow up to the front of the glacier, melting it increasingly4 rapidly.
 
Another team of scientists worked from an icebreaker ship at the front of the glacier. Exceptional5 sea ice break-up last year, meant they could survey over 2,000 square kilometres of the sea floor in front of the Thwaites ice shelf.
 
It's so important to understand what's going on in Antarctica today, particularly these big glaciers6 like Thwaites, because they are changing really quickly as the climate warms and as they melt, they are feeding more and more water to our global oceans, which is increasing the rate of sea level rise.
 
There is up to three and a half metres of sea level rise locked up in the ice here in West Antarctica. That's enough to reshape the map of the Earth, flooding many of the world's greatest cities.  
 
Understanding why this remote area is changing and how quickly it will do so, is essential if the world is to prepare for the rising waters to come.
