You can't tie a rope around the ice sheet. You can't build a wall around the ice sheets.

Tipping points are so dangerous because if you pass them, the climate is out of humanity's control: if an ice sheet disintegrates and starts to slide into the ocean there's nothing we can do about that.

When you reach the end of your rope, tie a knot in it and hang on.

We believe the ice sheet was not around all the time. It was only around during cool snaps of the climate.

It's the old adage that you tie a knot at the end of the rope and try to hang on.

This is our canvas. Our easel. This is how we paint, on fresh sheets of ice.
