Description:
50 years ago, NASA launched Nimbus to study Earth from space. Now, experts at the National Snow and Ice Data Center (part of CIRES), are recovering valuable data and images from old, long-lost film, and expanding their understanding of sea ice in the Arctic and Antarctic
Takeaway: Yes, there was more arctic sea ice. And the record includes both the largest and smallest extent for Antarctic sea ice. Big holes observed in Arctic ice. Don’t know why.
