Sea level rise is one of the impacts of the climate crisis that are already irreversible, as the UN warns. As the oceans warm, water rises mainly due to a phenomenon of thermal expansion, and to this is added the water poured in by both melting terrestrial glaciers and the continental ice of the poles as it thaws. It is precisely this last cause, the melting of the polar ice caps, that has been accelerating the most in recent years. Now, a new study published in Scientific Data, from the Nature group, offers the most precise portrait obtained to date on ice loss in Greenland and Antarctica.

Market logic justifies that what is only within reach of a few generally increases its value. This dynamic that sets the price of goods and services also infiltrates human behaviors, which end up conditioning decision-making. But what happens when what is at stake is an element on which the daily lives of citizens depend? The tension between the desire to collect travel experiences and to ensure the lives of the population of a vulnerable territory is what highlights the dynamics of tourism in the midst of an ecological crisis.Already in 2007, the award-winning editor-in-chief of the digital publication Travel Age West, Kenneth Shapiro, gave a name to a tourism phenomenon that was then beginning to proliferate: last-chance tourism. At that time, the concept referred to trips to areas threatened by environmental changes, such as the imminent threat of a volcano eruption or an expedition to observe an endangered species, among others. Over the years and with scientific evidence that the ecological crisis affects every corner of the planet, this word used in the jargon of travel agencies and nomadic gurus has undergone some nuance. Now, last-chance tourism is also the experience of visiting destinations that are at risk of disappearing or radically changing in the coming years due to damage caused by human pressure. Examples include visiting Australia's Great Barrier Reef, due to ocean acidification and rising water temperatures; or the Maldives islands, due to rising sea levels.Living between the thaw and the AMOC

But there is no need to change continents to observe the loss of ecosystems in areas where tourism plays a significant role. “In Iceland, the most evident change at first glance caused by the climate crisis is the retreat of glaciers. It is something that can be perceived even when comparing photographs taken just a few days or weeks apart,” explains Catalan photographer Natàlia Antequera, who lived in this Nordic country from 2021 to 2024. The Arctic is the region in the world suffering the highest temperature increase and, as a result, causes Iceland to lose 10 billion tons of ice per year, according to NASA data.At this rate, the European island could run out of ice by the year 2200. In nature's balance, every element plays its part, and melting is not only a sign of collapse in itself, but also a trigger. Specifically, in recent years, Nordic countries have been suffering from the stoppage of the AMOC (Atlantic Meridional Overturning Circulation), the part of the thermohaline circulation that passes by the Icelandic coasts and plays a key role in regulating the climate in the Northern Hemisphere. This danger prompted the island's government to declare the AMOC a national threat last November, becoming the first European state to take this stance.
