Cimino explained the threat to the Adélie food supply: “Changes in [sea] ice and temperature can cause changes in the food, krill and fish.” In some areas, she continued, “the fish populations have gone down a ton, so their major diet in those areas is krill. Two decades after leading a multi-national team on the first complete dogsled traverse of Antarctica, polar adventurer and National Geographic Explorer-in-Residence emeritus Will Steger reflects on the expedition–and what climate change means for our planet. From Acadia to Yosemite, here are spectacular spots for sunrises and sunsets in America’s public lands. And the world now has one more ocean! The bitter cold and three months a year without sunlight make Antarctica virtually uninhabitable for humans. For their new study, Adusumilli and his colleagues looked at some of the earliest data ICESat-2 collected, between April 2019 and June 2020. With up The National Geographic Society has announced it will officially recognize the area around Antarctica as the Southern Ocean, due to its unique ecological features and marine life. Antarctica’s climate is generally cold, dry, and harsh, but warming could yield unprecedented rain, or prematurely melt snowfall, creating puddles on the ground. Boersma adds there could be another fallout of climate change at play: As Antarctica warms, rain becomes more common—and rain is a penguin chick killer. Cimino believes it is imperative to prioritize conservation in the places that could shelter the Adélie penguins from climate change. It’s the ultimate “nature vs. nurture” debate, played out in real life before our very own eyes.

The photographer has been visiting Antarctica on and off since 2004, working on expedition ships from companies such as National Geographic and Hurtigruten. Often climate change refers specifically to the rise in global temperatures from the mid 20th century to present.

Wrap up warm, gang, and join us here at Nat Geo Kids as we check out ten brrr-illiant facts about glaciers!. Will they cause more surface melt and possibly add to the ice shelf hydrofracturing? They form over hundreds of years where fallen snow compresses and turns into ice. For periods of 30 years or more, however, distinct weather patterns occur. Vans and National Geographic come together to celebrate 130 years of the never-ending quest to explore. While the projections look grim for the penguins at northerly latitudes, the study did identify several refugia where the penguins could continue to thrive. The penguins nest on land during the austral (southern) summer, and migrate during the winter to the edge of the sea ice, where they are able to feed at sea. The documentary follows Will Steger, one of National Geographic’s most celebrated polar explorers and a climate change activist. With warming seas expected to send bigger, longer-lasting atmospheric rivers to Antarctica’s shores in the future, the research points to an understudied and little-understood process that could help to slow the ice sheet’s meltdown—or accelerate it, depending on the timing of the storms.

Using data from NASA’s Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) mission, launched into orbit in late 2018, a team of researchers found that atmospheric rivers were a major driver of precipitation, mostly snowfall, across West Antarctica in 2019, helping to replenish mass that the ice sheet is quickly losing.
