You beat me to it. The article says that “That figure rose to 252 billion tons lost per year beginning in 2009...”.
Well, what’s the uncertainty here? It could be something like +/- 300 billion tons. Then the above quote would be meaningless.
What’s also kind of interesting is that parts of Antarctica are deserts. No snow. It’s as if it is too cold to snow. A warmer planet is a wetter planet. A warmer planet should increase snowfall in the especially cold areas of the planet.
