In einem gut gefüllten Hörsaal hält ein Redner einen Vortrag. Er steht an einem Tisch mit verschiedenen Exponaten, darunter ein großes, braunes, bootsähnliches Objekt und ein blauer Behälter, und zeigt mit einem Zeigestab auf ein technisches Gerät. Der Redner blickt zu den Zuhörern. Die Zuhörer sitzen in den Reihen und schauen aufmerksam zum Redner. Auf zwei großen Projektionswänden sind Folien mit dem Titel "Entwicklung eines Algenzucht-Verfahrens" zu sehen, die Text und Grafiken zeigen. Am linken Rand des Hörsaals steht ein Roll-up-Display mit weiteren Informationen. Durch die Fenster fällt Tageslicht in den Raum.

Thawing Arctic Permafrost Releases Ancient Carbon, Intensifying Climate Change A new study reveals that as Arctic permafrost thaws, it is releasing vast amounts of carbon that have been trapped for thousands of years, exacerbating global warming. The research, led by Michael Rawlins at the University of Massachusetts Amherst, shows that thawing permafrost is changing water systems, with rivers in northern Alaska carrying more dissolved organic carbon (DOC) into the ocean. These changes are linked to a longer thaw season, with impacts on the region's ecosystem and carbon cycle. The research highlights that the Arctic’s rivers play a significant role in global water systems, delivering a substantial amount of freshwater to the ocean, especially the Arctic Ocean. Over the next 80 years, the region could see a 25% increase in runoff, further releasing DOC into the ocean, where some of it turns into carbon dioxide, amplifying climate change. While the study offers new insights into the thawing process, it underscores the need for more data to fully understand its effects on global warming and coastal ecosystems.

Study shows thawing permafrost releases much more greenhouse gas than expected For a long time, Arctic permafrost has acted like a giant frozen lid: it locks away carbon-rich soils and slows the escape of gases that can warm the planet. But new lab experiments from the University of Leeds suggest that once that lid starts to thaw, the ground can become dramatically more “leaky,” making it much easier for climate-forcing gases to move through the soil and into the atmosphere. The study reveals that thawing permafrost can become 25 to 100 times more permeable, meaning gases can travel through it far more easily than when it’s frozen. Emissions from thawing permafrost Permafrost covers huge areas of the Arctic. It’s been frozen for long periods, which has allowed organic material – and the carbon inside it – to accumulate rather than fully decompose. Globally, permafrost is estimated to contain about 1,700 billion tons of carbon, roughly three times the amount currently in the atmosphere. If warming causes more of that carbon to be released as carbon dioxide and methane, it risks creating a feedback loop: warming causes thaw, thaw releases gases, gases cause more warming. “It is now widely recognised that climate change is leading to significant thawing of permafrost, with a...

The Alaskan permafrost is thawing. Here's why that's so worrying Thawing permafrost is among climate science’s worst “positive feedback loops”: As the world warms, permafrost—essentially frozen soil—thaws, releasing fresh water and carbon into the environment. That release further fuels climate change, driving more warming. (Thawing permafrost has also raised concerns about unleashing new pathogens on humanity.) And in Alaska, the loop seems to be speeding up. In a new study, researchers track how thawing permafrost in the North Slope region of Alaska—an area the size of Wisconsin—has added fresh water and dissolved organic carbon to estuaries off the Alaskan coast between 1980 and 2023. In more recent years, the region released nearly 12 cubic kilometers—three trillion gallons—more water per year than it did in the 1980s. That’s enough to fill more than 4.5 million Olympic swimming pools, estimates Michael Rawlins, the lead author on the study and an extension associate professor of earth, geographic, and climate sciences at the University of Massachusetts Amherst.

Ancient Carbon Is Flooding Arctic Rivers As Permafrost Melts Faster Thawing Arctic ground is unleashing ancient carbon—and speeding up climate change. Scientists have taken a detailed new look at what happens when Arctic permafrost begins to thaw, revealing major changes to water flow and carbon movement across northern Alaska. The research, led by geoscientist Michael Rawlins at the University of Massachusetts Amherst, provides one of the most precise views yet of how this rapidly warming region is evolving. The team focused on a region of Alaska’s North Slope about the size of Wisconsin, where hundreds of rivers and streams drain into the Beaufort Sea. Using 44 years of model data at a fine one-kilometer resolution, they found that runoff is increasing significantly, more previously frozen carbon is entering rivers, and the thawing season now stretches later into the year, reaching late summer and fall. These findings were recently published in Global Biogeochemical Cycles. Why Arctic Rivers Matter for the Global Climate Arctic rivers play an outsized role in Earth’s systems. They carry about 11% of the world’s river water into an ocean that holds only 1% of global ocean volume. This makes the Arctic Ocean highly sensitive to changes happening upstream. While snowmelt is a major contributor to river flow,...

Siberia’s Batagaika Depression Expands as Permafrost Thaws The Batagaika ‘crater’ in eastern Siberia is not a meteorite impact site but a massive thermokarst depression created by the collapse of permafrost beneath the surface. Located in the Republic of Sakha—the largest subnational region on Earth—the feature has grown from a small patch of exposed frozen ground after Soviet‑era logging and road‑building in the 1960s into a chasm roughly 2.5 kilometers long and nearly 1,000 meters wide. Over the last several years, it has expanded by about 14 meters per year in both length and width and deepened to cliffs taller than 50 meters. Warmer Siberian summers accelerate the melting of the underlying permafrost, which in turn exposes more ice‑rich soil to thaw, ensuring the depression continues to widen and deepen for the foreseeable future. Scientists see Batagaika as an accidental window into hundreds of thousands of years of geological history, with well‑preserved fossils of trees, animals, and vegetation that reveal past climates much warmer than the present. The pit has also yielded exceptionally preserved specimens such as a 42,000‑year‑old foal, a saber‑toothed tiger over 30,000 years old, and a 50,000‑year‑old baby mammoth. Yet, the thaw also raises concerns: ancient pathogens once trapped in the ice could re‑emerge, and the release of vast amounts of organic carbon stored in the permafrost adds carbon dioxide and methane to the atmosphere, reinforcing global warming. Estimates suggest Batagaika alone emits about 5,000 tons of CO₂ per year, underscoring how thawing permafrost can turn a local landform into a globally significant climate feedback.
