After the Amixem video, what you need to know about the calving of glaciers due to the climate


A YouTube channel with 7.7 million subscribers talks about the consequences of global warming on the parting of glaciers: a need, to the rescue of scientific information, in the face of eco-anxiety. Humor proves to be a particularly effective vehicle for scientific information. This is how, on the most important issue of our century, climate change, many YouTubers and YouTubers have a letter to support our work as science journalists, as we do for example in our Environment section. But few, with more than a million subscribers, mention the subject. The Amixem channel has 7.7 million. This one specializes in challenges or reaction videos. And it is especially in this quality that his subscribers know him, who are therefore united to him and his team for the moment of entertainment that he offers them. Occasionally, however, a “scientific exploration” type video is placed there, for example in the company of the famous Mike Horn. Except that the one that aired on Sunday, August 14, 2022 is still a little different: the YouTuber goes to Greenland to witness the birth of glaciers (when whole pieces break off during the summer). Throughout this video, there is no lack of humor, of course, but educational content is placed there – Aximen recalls the impact of climate change on childbirth, the frequency of which has increased in a problematic way. But, better: the YouTuber appeals to a real scientist, a glaciologist, Gaël Durand, to interview him on several occasions. This intervenes, therefore, to detail the birthing process, but also to remember the role of the climate crisis, its magnitude, the reasons for the Paris Agreement intended to keep the planet at 1.5 degrees. In the description, too, Amixem slips several links to the key points of the IPCC report and other such educational elements. Interview with Gaël Durand during the video. // Source: Amixem Already viewed by nearly 2 million people, the YouTuber’s documentary belongs to a type of content that can play an important role today. Because in reporting on climate change, we face a number of obstacles: the public’s sense of being confronted with moral lessons; the apocalyptic impression capable of generating ecological anxiety and, therefore, the lack of desire to devote oneself to learning about these issues. ; The very scientific and technical nature of the explanations. When productions evoke the subject without advancing directly as scientific and educational content about climate change (we also think of a film like Don’t Look Up), we overcome many of these obstacles. Not that it is necessary to pass exclusively on this entertainment vehicle. However, the latter remains undervalued: much more is needed, both to address the issue and to highlight scientists like Gaël Durand. To go further Yes, the glaciers are melting due to climate change As for the situation evoked in the Amixem video, it is true, because it is also what is pointed out in the scientific literature. “Greenland’s ice sheet is losing mass at an accelerated rate during the 21st century, making it the main culprit behind sea-level rise,” noted a study published in Nature in August 2020 .The glaciers of Greenland, which sink into the Arctic waters through the steep sides. coves, or fjords, are one of the main causes of global sea level rise due to climate change. climate,” also notes NASA, which reports a study published in Science Advances in 2021. When an ice sheet is in equilibrium, the amount of snow that accumulates on top of glaciers is equal to the ice lost (per melting, evaporation, and calving.) But since the 1990s, observations have shown an imbalance, because the rate of ice loss is greater than intake. As a result, glaciers are retreating. In fact, explains the publication, increasingly warm ocean waters and warmer air.So, while the phenomena of melting and calving are natural, their disproportionately increased frequency is not: it is linked to climate change, which is linked to our activities for the emission of greenhouse gases. And it is far from just referring to Greenland. A study published a few days ago, in August 2022, showed that the water had never been so warm around the world’s largest glacier in Antarctica.For more
