What’s happening to Antarctica’s glaciers right now?

Antarctica has lost about 3 trillion tons of ice since the early 1990s. today, Losses are accelerating as warmer seas melt and destabilize floating ice shelves Blocked glaciers in West Antarctica, causing them to flow into the sea more quickly.

Is Antarctica gaining or losing ice?
