Antarctica’s ice loss is locked in, and extra snowfall won’t save it
A new study published in Nature Geoscience indicates that significant ice loss in Antarctica is now inevitable regardless of future global warming mitigation efforts. Researchers warn that even meeting the 1.5C Paris Agreement goal will not prevent the resulting sea-level rise, which poses a major threat to coastal populations.
Why it matters
This finding suggests that coastal adaptation strategies must be prioritized as a primary response to climate change, as the window to prevent large-scale Antarctic ice melt has likely closed.
A glacier front meets the sea in Antarctica. The ice sheet holds enough water to raise global sea level by about 190 feet (58 meters).

Sea-level rise is one of the most visible signs of climate change, one that is threatening low-lying coastal communities around the world. Today, about 1 billion people live in coastal areas; about 100 million live within 1 meter (3.3 feet) of sea level, highly exposed to coastal flooding.
Over the long term, when it comes to future sea-level rise, one place matters more than any other: Antarctica.
