More of us than ever want to see the ice continent. But is the environmental awakening many return with worth the emissions and possible environmental damage?

The species at risk include flowering plants, moss and lichens, tough invertebrates and breeding seabirds.
Scientists used satellites to map tens of thousands of glacial landforms in Antarctica’s highest mountains.
A Pandoravirus has been revived after remaining dormant in the Siberian permafrost for nearly 50,000 years.
Emperor penguins survive in a ‘Goldilocks zone’ between too much sea ice and too little. Climate change is having an impact.
The U.S. Antarctic Program struggles to keep women safe – and through the continent’s history, discrimination and prejudice are rampant.
A transcript of an episode of The Conversation Weekly published on September 22, 2022.
If and when the Thwaites Glacier melts, it will result in nearly 0.6 metres of sea level rise, but it holds back another three metres of sea level rise lurking within the Antarctic continent. Listen to The Conversation Weekly podcast.
The place where oceans turn into ice holds the key to understanding some of the complex interactions of Earth’s climate. Thankfully, we’re making progress.
Southern Ocean heat uptake accounts for almost all the planet’s ocean warming, thereby controlling the rate of climate change.
A recent report reveals 72% of women stationed in Antarctica have experienced sexual harassment. This is a shockingly high number – but change is possible.
But new research offers some hope if we are able to keep climate change under control.
Antarctica’s ice shelves have helped insulate it from dangerous levels of ice loss. But this is changing.
The findings underscore the urgency of limiting global warming to below 1.5°C, to avert the most catastrophic climate harms.
Interestingly, we also found a major period of ice loss in Antarctica was followed by a period of gain, starting some 5,000 years ago.
As nations pledge to preserve swaths of ocean within their territorial waters, a marine scientist explains why some marine protected areas shelter ocean life more effectively than others.
Thwaites Glacier’s ice shelf appears to be splintering, and scientists fear it could give way in the next few years. A polar scientist takes us on a tour under the ice to explain the forces at work.
These temperatures are well below average, even for the middle of winter.
Scientists just grew plants in soil from the Moon, but Antarctica has long provided researchers with the perfect place to test their agricultural techniques for a future in space.
Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.
