Disappearing landscapes: The Arctic at +2.7°C global warming

Science, Journal Year: 2025, Volume and Issue: 387(6734), P. 616 - 621

Published: Feb. 6, 2025

Under current nationally determined contributions (NDCs) to mitigate greenhouse gas emissions, global warming is projected reach 2.7°C above preindustrial levels. In this review, we show that at such a level of warming, the Arctic would be transformed beyond contemporary recognition: Virtually every day year have air temperatures higher than extremes, Ocean essentially ice free for several months in summer, area Greenland reaches melting least month roughly quadruple, and permafrost half what it was times. These geophysical changes go along with widespread ecosystem disruptions infrastructure damage, which, as here, could substantially reduced by increased efforts limit warming.

Community Perspectives on Risk and Emergency Preparedness for Shipping Disasters at the Eastern Entrance to the Northwest Passage

Published: Jan. 1, 2025

Over the past two decades there has been an increase in ship traffic Arctic Canada leading to concerns about increased risks region, including heightened probabilities of a major shipping accident or disaster. This situation is challenging emergency preparedness capacities coastal communities and governments. The Northwest Passage (NWP) particular interest due accessibility related climate change sea ice reduction its' rising popularity as potential maritime trade route and/or cruise hot spot. community Pond Inlet, Nunavut, sits on eastern entrance / exit NWP with firsthand experiences increases volume. To explore perspectives for different types accidents events, scenario-based survey was utilized residents Inlet. Results study revealed that Inlet have low level confidence their perception response timing if occurred, anticipation high levels devastation environment, along insights into what disaster could look like opportunities Disaster Risk Reduction.

Enhancing Sea Ice Concentration Resolution in a Northern Sea Route Strait Using a Generative Adversarial Network

Journal of Geophysical Research Machine Learning and Computation, Journal Year: 2025, Volume and Issue: 2(1)

Published: Feb. 17, 2025

Abstract Straits are strategically and economically vital due to their role as maritime choke points, controlling access regions resources. This is particularly pertinent in the Arctic, where navigability along critical shipping routes relies on through straits that frequently ice impacted. With retreat of Arctic sea under anthropogenic climate change, scenarios using CMIP6 projections have potential provide valuable insights into future accessibility regimes. However, typical model spatial resolutions limit capacity represent accurately. study introduces a novel approach, Ice Concentration Enhancement Generative Adversarial Network (ICE‐GAN), enhance resolution concentration (SIC) Vilkitsky Strait, passage Northern Sea Route (NSR). By employing ICE‐GAN model, functionally increased from . The approach prototyped ERA5 Reanalysis training data predict cover for 2021 2022. results indicate method outperforms, across multiple metrics, standard interpolation techniques such Nearest Neighbor Interpolation Bilinear Interpolation, both used models, well super‐resolution convolutional neural network, best practice SIC. Importantly, robust non‐stationarity record. Moreover, by incorporating physics‐informed ICE‐GAN, able further improve accurate representation studied Strait.

Decarbonizing Arctic shipping: governance pathways and future directions

Frontiers in Marine Science, Journal Year: 2025, Volume and Issue: 12

Published: Feb. 21, 2025

Arctic shipping is a significant source of greenhouse gas (GHG) emissions, including carbon dioxide and black carbon, which intensify climate risks in the region. While International Maritime Organization (IMO) has established Code for Ships Operating Polar Waters (Polar Code) to address environmental safety concerns polar navigation, it falls short promoting decarbonization shipping. The collaboration between IMO Council, along with contributions Council’s task forces, essential but requires further strengthening. In response crisis, raised standards, leading efforts promote low-carbon growth through measures such as sulfur limits, heavy fuel oil bans, reductions emissions. Despite these initiatives, governance remains fragmented. To achieve meaningful decarbonization, must be strengthened expanded into unified regulatory framework. Additionally, enhanced Council crucial maximize their collective impact. As key player shipping, China strengthen compliance international regulations updated domestic legislation policies. By actively engaging multilateral mechanisms developing port state control inspection network, can play pivotal role advancing energy efficiency contributing more coordinated sustainable approach region’s challenges global maritime governance.
