Antarctic ice shelf retreats happened before

...s ago the ice shelf retreated, allowing the sea to flood into the lake. The ice shelf didn't reform until 1500 years later, and has been present ever since. The findings are particularly relevant for other studies on the West Antarctic Ice Sheet where scientists have found that a relatively warm current, ...

Beneficial Beetles Battle Pesky Saltcedar

...low their banks, saltcedar bushes can trap natural flood debris, blocking waterflow and causing new, erosive channels to form. These channels sometimes undercut farm roads and fields, causing them to collapse. What's more, river rafters or thirsty wildlife and livestock often can't get through dense thick...
