Antarctica: A Remote Sentinel with Global Consequences 

Antarctica is the planet’s climate sentinel, according to Eric Rignot, the Distinguished Professor of Earth System Science at the University of California, Irvine and senior NASA scientist. Rignot spoke with Ahmetcan Uzlaşık on the sidelines of the Antarctic Futures Symposium in late April 2026.

Antarctica is essentially a sentinel of the planet. It shows very clearly how Earth is responding to greenhouse gas emissions, and these effects tend to be amplified in the polar regions. The most important aspect is the sheer amount of ice it contains. Antarctica holds enough ice to raise global sea levels by around 60 metres.

We are not worried about that happening tomorrow, but even a much smaller increase is critical. A rise of about one metre per century would already have massive global consequences.

We view Andromeda as the Antarctic research station of the 22nd century. It is designed to focus on science while maintaining a minimal carbon footprint.

The idea is to move toward zero-emission operations. Many current Antarctic stations still rely heavily on fossil fuels for heating, transport, and logistics. We want to move away from that by using renewable energy, particularly wind, and storing it as electricity or hydrogen.

We also want to develop zero-emission mobility systems. In Antarctica, this is especially important because there is no infrastructure like fuel stations. If we are doing science there, we should not be contributing to the problem we are trying to study.

If we are doing science there, we should not be contributing to the problem we are trying to study. 

Yes, absolutely. The Princess Elisabeth station is a great example. It has been operating for around 20 years as a zero-emission station with full water recycling.

However, even that station still relies on fossil fuels for mobility. What we want to do next is go beyond that, working with industrial partners to develop electric and fuel cell vehicles adapted to Antarctic conditions.

It is important for scientists to feel that the way we conduct research is aligned with sustainability principles.

Technology is evolving very quickly. We no longer need to send as many people into the field as before. We can install long-term observatories that continuously collect data and transmit it back to laboratories via the internet. In many ways, we are trying to build something similar to global weather station networks, which currently do not exist at scale in Antarctica.

It is still very limited and not sufficiently developed. The observation network is not mature and is often under threat due to funding constraints. There is also a lack of awareness among policymakers about how critical these observations are. If we want to understand and model how Antarctica interacts with global climate, we need consistent and long-term data. 

We cannot model a system that we do not observe. That is why building a comprehensive observation system, both on land and in the surrounding ocean, is essential. 

Sea level rise leads to a permanent loss of coastal land. This affects infrastructure such as airports, ports, and housing, which cannot easily be relocated inland.

Beyond direct impacts, there are also indirect consequences. It affects economies, trade, safety, and even national borders. In some low-lying regions, particularly island nations, entire populations may be forced to relocate.

This creates a new form of climate-driven migration. It is not just a local issue but a global one, requiring international cooperation and solutions.

Genomics is about studying the genetic makeup of organisms. In Antarctica, it is a largely unexplored field.

We are interested in understanding the microbiomes and ecosystems in the Southern Ocean and around places like Andromeda. These environments host life that has adapted to extreme conditions, often only active for short periods during the year.

Much of this biodiversity has never been studied in detail. This includes everything from larger species like birds to microscopic organisms such as phytoplankton and bacteria, which play a key role in the carbon cycle.

There is also a sense of urgency. As the climate changes, these ecosystems are changing as well. We need to understand them before they are altered or lost.

Drone technology is particularly exciting. It is evolving rapidly and can now carry advanced instruments such as radar sounders, gravimeters, and laser altimeters.

This allows us to expand our observational reach over hundreds of kilometres without relying on aircraft, which significantly reduces emissions.

Another major development is real-time data transmission. Technologies like satellite internet now allow us to receive data from Antarctica almost instantly, rather than collecting it manually once a year.

These innovations are transforming how we conduct research and opening up entirely new possibilities for understanding the Antarctic system.
