The World's Largest Iceberg Is Drifting Three Miles Into the Ocean Each Day
That's correct. The world's largest iceberg, A23a, is currently drifting three miles into the ocean each day. It broke free from the Filchner-Ronne Ice Shelf in 1986 and has been grounded on the seafloor for decades.
However, in recent months, it has begun to move again, thanks to strong winds and currents. The iceberg is now about 1,500 square miles in size and weighs nearly one trillion metric tons.
The movement of the iceberg is being closely monitored by the British Antarctic Survey. They are concerned that the iceberg could break apart as it travels through the Weddell Sea, which is a notoriously rough and unpredictable body of water.

The movement of A23a is a reminder of the rapid pace of climate change in Antarctica. The continent is warming at twice the global average, and this is causing glaciers and ice sheets to melt at an alarming rate.
It is important to monitor the movement of icebergs like A23a so that we can take steps to mitigate the risks they pose.
We also need to take action to reduce greenhouse gas emissions and slow the pace of climate change. This is the only way to ensure the future of Antarctica and the planet as a whole.
