Climate Crisis in Antarctica

Antarctica is at a crossroads. The global climate crisis is interrupting natural processes across large parts of Antarctica and the Southern Ocean.

As we stand on the brink of catastrophic change, the actions we take over the next decade will determine the course of human civilization for generations.

What’s happening?


The polar regions are the first to be affected by the heating climate, and dramatic changes are already underway in Antarctica.

Floating ice shelves are melting rapidly, raising concerns about sudden, uncontrollable sea level rise. The Antarctic Peninsula, a popular tourist destination, is one of the most rapidly warming places in the Southern Hemisphere, with average summer temperatures increasing by over 5°F (3°C) between 1970 and 2020. 

Since the 1970s the Southern Ocean has absorbed as much as 75 percent of the excess heat created by humans, and 40 percent of the carbon dioxide. Warmer, more acidic oceans are already impacting Antarctic ecosystems, with many penguin colonies shrinking, and in some cases disappearing altogether.


What are the impacts?

Antarctica and its ice, ocean and ecosystems play a critical role in regulating the global climate. Together they help slow global heating, drive important ocean currents, and contribute to the drawdown of millions of tons of carbon dioxide from the atmosphere.

The climate crisis is disrupting these delicate systems. They are changing rapidly, with effects that will be felt around the world.

Human activity is causing changes in our climate, and the natural systems that support life as we know it.

Between 1980 and 2020, several penguin colonies on the Antarctic Peninsula vanished.

Antarctic ice is changing. Collapsing ice shelves could lead to several feet of sea level rise by 2100.

The Southern Ocean is slowing climate change by absorbing excess heat. But it comes at a cost.

Why it’s important


What happens in Antarctica as the planet heats will affect all of humanity. A warming Southern Ocean threatens to slow global ocean circulation and drive extreme weather events across the globe. Find out more.

Melting Antarctic ice has the potential to raise global sea levels by hundreds of feet. Even a few feet of sea level rise would be catastrophic for millions of people, destroying critical sources of freshwater and farmland with saltwater, and displacing millions of people. Find out more.

What ASOC is doing

ASOC advocates for policies that will build Antarctic ecosystem resilience in the face of climate change. We work to build awareness of the impacts of climate change on the Antarctic environment through public advocacy, reporting to Antarctic governance meetings, and conducting outreach to governments.


How we work

As the only environmental NGO invited to observe Antarctic Treaty meetings, we represent the Antarctic conservation community at the highest levels of Antarctic governance. We work within the system to address the climate crisis in the following ways.

We support adaptive management systems which incorporate uncertainty and respond to new information.

It’s not too late to act. The greatest threats to Antarctica today come from right here – where we live. As Antarctica nears irreversible tipping points, we must take urgent action now to secure a safe climate future.
