Key Science Findings!

<aside> 💡 This work found out that...

• Including hydrology in a paleo-scale ice-sheet model makes the ice sheet evolve on a faster, more realistic timescale that better matches geologic observations.
• Soft-bedded sliding (sediment cover) further speeds up ice flow and the equilibrium timescale compared to hard-bedded sliding (over the bedrock) of the Laurentide Ice Sheet. </aside>
