A video reveals mature jellyfish under the Arctic sea ice, where they aren’t supposed to be.
The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. Lamont-Doherty Earth Observatory’s Marco Tedesco describes the changes underway.
Fast-rising temperatures on the Antarctic Peninsula are having an impact on the ice and marine life, and providing clues about future ecosystem changes elsewhere.
We hear a lot about polar bears and other Arctic mammals in connection to climate change, but what about biodiversity in Antarctica?
I returned to New York on Monday, but Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack remain working in Barrow, Alaska for another week. They’ll continue to collect data and samples in a race against deteriorating Arctic sea ice conditions as the onset of summer causes the ice to thin and break up.
