Perceptions of the Arctic take centre-stage in the recent work of Hamburg-based conceptual artist Swaantje Güntzel, created during her tenure as the resident Art Fellow at the Research Institute for Sustainability - Helmholtz Centre Potsdam. Now several galleries across Germany are showcasing Güntzel’s art, including works from previous years.

The 11th annual Potsdam Science Day will take place on Saturday, 4 May 2024. This year the event will be held on the GFZ Campus on Telegrafenberg. The Research Institute for Sustainability (RIFS) will be hosting a booth on site, where visitors can play a climate game developed by the European research project 1.5-Degree Lifestyles and learn about how making changes to different everyday activities can reduce our impact on the climate.

In a survey conducted by the Research Institute for Sustainability (RIFS) in June and July 2023, around 80 per cent of the 64 cyclists surveyed stated that a speed limit of 30 km/h should be maintained on Leipziger Straße in the central Mitte district of Berlin. Pedestrians surveyed expressed similar views. There is also strong support for the creation of a bike lane that is physically separated from motorised traffic.

The Marine Regions Forum 2023, held last November in Dar es Salaam, Tanzania, highlighted ways to work together towards a common goal of improved ocean governance at national, regional, and global levels. It brought together ocean actors and experts from the Western Indian Ocean region and from other parts of the world to exchange on pressing ocean issues and explore ways forward. The organisers have now released two publications that offer insights into the discussions and present a set of key messages.

Tipping elements of the Earth system should be considered global commons, researchers argue in a new paper published in the renowned journal Proceedings of the National Academy of Sciences (PNAS). Global commons cannot - as they currently do - only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.

Even if the global community were to double down in its efforts to protect the climate, it would not be able to give the Arctic Ocean back its ice. But, in a symbolic act, Hamburg-based conceptual artist Swaantje Güntzel has done just that: on 18 November, at Båtsfjord in the far north of Norway, she produced ice cubes from meltwater taken from the North Pole and let them slip into the sea. This artistic intervention is part of Güntzel's year-long fellowship at the Research Institute for Sustainability - Helmholtz Centre Potsdam (RIFS).

The transport sector is a major contributor to environmental degradation, including air and noise pollution, damage to ecosystems and human health. To monitor air and noise pollution and generate data that will aid in assessing their health impacts related to it, the new research project Net4Cities will develop research infrastructure in eleven European cities in ten countries. This research and infrastructure will support efforts to implement the Zero Pollution Action Plan as part of the European Green Deal. The project is coordinated by the Research Institute for Sustainability (RIFS) in Potsdam.

Hosted in the Western Indian Ocean (WIO) region by the United Republic of Tanzania and the Republic of Seychelles, the Marine Regions Forum 2023 convened under the theme, “Navigating ocean sustainability in the WIO and beyond.” The three-day conference was co-hosted by the United Republic of Tanzania and the Republic of Seychelles and brought together experts from the WIO and other marine regions to strengthen cooperation and coordination for marine governance in the WIO region and beyond by sharing knowledge and best practices.

The ocean will play a key role in efforts to tackle the climate crisis, according to scientists and the Intergovernmental Panel on Climate Change (IPCC). The use of so-called “negative emissions technologies” to enhance carbon sequestration and storage in the ocean is increasingly being discussed. In a study published in the scientific journal "Frontiers”, RIFS researchers Lina Röschel and Barbara Neumann describe the challenges that these technologies present for both the marine environment and society, and identify cornerstones for their responsible use.

The International Seabed Authority (ISA) has convened in Jamaica for its annual meeting, which will include crunch talks on proposals to allow deep-seabed mining following the expiry of a two-year deadline to finalize regulations governing the removal of minerals from the international seafloor. RIFS researcher Pradeep Singh examines the legal context of this turning point in the history of the ISA in a new discussion paper – “A ‘deadline’ expires: Quo vadis, International Seabed Authority?” – presented to delegates in Kingston.

Cities in the Global South are particularly vulnerable to the impacts of global warming. Rising temperatures are worsening the effects of ozone pollution, for example. Like many other cities in the Global South, Santiago de Chile is highly segregated along socio-economic lines. RIFS scientist Tabish Ansari and a team of researchers have examined and compared the effects of heatwaves and ozone episodes in different areas of the city.

More inclusive, equal and just ways in which Arctic research is conducted and research programs and funding processes are conceived, these are some of the main goals of the Roadmap to Decolonial Arctic Research. On 19 June 2023, a group of non-Indigenous and Indigenous rights holders and engaged scholars, from RIFS and several other organisations across Europe and the Arctic, presented the Roadmap to Decolonial Arctic Research to the public. The publication addresses the greatest challenges, needs and potentials of Decolonial Arctic Research over the next ten years.
