Where is the sea-ice going?

Antarctic sea-ice

The news headlines are covering all kinds of world issues – the Russo-Ukrainian war, the revolution in Syria, Donald Trump’s coming second term in the White House, world economics, and more.

But there’s an event going on of far greater importance than any of those other issues, and that concerns the latest results of research into Antarctic sea-ice.

The problem? It’s melting much faster than we thought.

And why is that such a big deal? Because of the implications that global warming is progressing so much faster than we realised, combined with the potential loss of ice shelves, one and a half metres of sea-level rise far sooner than we expected, and the further potential for catastrophic sea level rises much, much greater than that.

That’s alarming in anyone’s book. But it’s not alarmist, it’s just stating an unpalatable truth. The time to begin thinking about consequences and mitigation is now, not in ten or twenty years time. And it’s most certainly way past time to deny that climate change is a thing at all.

I urge you to listen to the New Scientist podcast on this, episode 279 released on 6th December 2024. It has all the details.
