The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
Sea levels are rising globally at record-breaking rates and Antarctica is playing an increasing role. Matt King

Weigh-in reveals Antarctica’s losing 190 million tonnes a day

A small slice of Antarctica turns up along your coastline each year. We’re all glad it’s just a small slice, given Antarctica could deliver a total sea-level rise of 59 metres. That’s not going to happen…

Explainer: what is the Antarctic ozone hole and how is it made?

SAVING THE OZONE: Part two in our series exploring on the Montreal Protocol on Substances that Deplete the Ozone Layer – dubbed “the world’s most successful environmental agreement”. Yesterday’s article…
