The lingering Laurentide Ice Sheet may have masked the true extent of Antarctic ice loss—offering a warning for future change. 100% = global mean sea level rise; areas above saw higher-than ...

Imagine that a massive ice sheet covered Canada and oozed down over a large part of the northern United States, like icing spilling down the side of a cake. That was the situation, somewhere ...

A newly discovered mechanism for the flow and freezing of ice sheet meltwater could improve estimates of sea level rise around the globe. Researchers from The University of Texas at Austin, in ...

Snowball Earth defines periods of our planet's history when ice spanned the globe, even reaching the equator. The planetary-scale freeze is thought to have been driven by ice sheet expansion ...

At the time, the massive Laurentide Ice Sheet, which stretched over North America as far south as Pennsylvania, started to recede. Melting ice flooded into the oceans, ...

As the weight of the Laurentide Ice Sheet was redistributed around the planet, parts of North America began to bounce back up. (Today, land around Canada's Hudson Bay is still rising by around 1 ...
