Greenland Fossils Indicate Potential for Major Sea-Level Rise

New evidence reveals Greenland's ice sheet melted significantly in the past, suggesting vulnerability to future climate change.

Scientists discovered plant and insect fossils under Greenland's ice, indicating previous periods of significant melting.
The findings suggest Greenland's ice sheet is more susceptible to melting than previously understood.
If Greenland's ice melts entirely, global sea levels could rise by up to 23 feet.
Current atmospheric carbon dioxide levels are higher than during previous ice-free periods in Greenland.
The study underscores the urgent need to reduce greenhouse gas emissions to mitigate future sea-level rise.
