Antarctica, at the heart of questions for the future?

A still little-known continent, Antarctica plays a major role in climate regulation and has a rich biodiversitybiodiversity unknown. But it is above all a threatened continent that is warming up faster than the planetary average. By the end of the century, tipping points could be reached on some glaciersglaciers and generate major risks related to rising water levels, biodiversity threatened by habitat loss that is melting…

For all these reasons and many more, it seemed obvious to us to devote the introductory file of the new Mag’ Futura to this subject. Without further ado, let’s lift the veil on the major topics that we have in store for you for this committed file.

• Melting Antarctica threatens the world

The “White Continent” is heating up vitessevitesse accelerated, under the effect of complex mechanisms combining ocean currents, winds, influence of cloudsclouds… Will the glaciers give way sooner than expected? Is their fate already sealed or are they in danger of rapidly crossing a tipping point if we continue to warm the climate? We take stock of what science today understands about these crucial mechanisms whose evolution will have consequences for the level of the oceans and the climate on a planetary scale.

• Gallery: ice portraits

Pascale Sury, photographer of the living, surveys the six continents to ” show the beauty and fragility of our Planet and of life “. A mission that has led her on several expeditions to Antarctica. She gives us here six portraits of beings whose otherness and grace are so many WindowsWindows on the fragile mysteries of the white continent.

• Biodiversity: cold sweats in Antarctica

From plankton to whales, climate change and human activities are jeopardizing the fragile balances that govern ecosystemsecosystems from the South Pole. Beyond the local erosion of biodiversity, the health of the world’s oceans could take a hit if the Southern Ocean, a major source of nutrientsnutrientswas losing its vitality.

• Heidi Sevestre: “Letting Antarctica melt is criminal”

The glaciologist Heidi SevestreHeidi Sevestre is a fine connoisseur of polar environments and glaciers that she studies in the field during scientific expeditions. She tells us here how she discovered Antarctica, how researchers are taken aback by the speed of the deterioration of the situation and why this urgently requires general mobilization.

• When Dumont d’Urville discovered Adelie Land

The discovery of Adélie Land by the expedition of Jules Dumont d’UrvilleJules Dumont d’Urville, January 21, 1840, is one of the great dates in polar history. The explorations that followed owe him a great deal. The journalist Michel IzardMichel Izard went to Antarctica in the wake of this pioneer, and drew a fascinating story (Adelie, my love. Journey through the ice, ed. Pocket, 2019). He returns for us to the journey of these adventurers and the importance of their legacy for science.

…And many other subjects to discover in the magazine!
