What is the status of sea ice around Antarctica?

The Southern Ocean around Antarctica freezes to form sea ice every year. Scientists use observations from satellites to monitor the sea ice extent throughout the year.

Sea ice melt in Antarctica is a seasonal occurrence that usually begins in September (the end of Southern Hemisphere winter) and continues into February (end of Southern Hemisphere summer). As the pole warms during summer, the sea ice around the continent breaks up and melts. Continue reading

What is the prediction on the rise of sea level?

The National Oceanic and Atmospheric Administration, or NOAA, routinely monitors sea level and makes predictions of how it will change with time. The observations are based on a combination of tide gauge data and satellite observations.

Continuously tracking how and why sea level is changing is an important part of informing plans for adaptation to global changes. In a recent speech, former President Donald Trump falsely stated that “the ocean will rise 1/8 of an inch over the next 200 to 300 years.” Continue reading
