What to know about Giant ice mountains on the other side of Earth once dictated Australia’s climate – new study

The article discusses a study published in 'Climate of the Past' which suggests that massive ice sheets in North America during the last ice age influenced rainfall patterns in Australia. The researchers used climate model experiments to demonstrate how the height of these ice sheets redirected global wind patterns, affecting the southern hemisphere.

What happened

During the most recent ice age, much of North America disappeared beneath ice sheets several kilometres thick.

Why it matters

These frozen giants covered most of present-day Canada and parts of the northern United States, while smaller ones spread across northern Europe.

Common ground

They dominated the landscape for thousands of years, storing so much water that global sea levels fell dramatically.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
