Both policymakers and the technology industry need to do more to combat the ever-growing demand for data and its associated energy impacts. In this study, based on novel corporate data, expert interviews, focus groups with members of the public, extensive site visits across Greenland, Iceland and Norway and a literature review, we look at the energy and climate impacts of existing and proposed datacenters, both quantitatively and in terms of stakeholder and public perceptions.

The latest IPCC report on Ocean and Cryosphere in a Changing Climate, which builds upon previous IPCC’s reports, established a causal link between anthropogenic impacts and ocean acidification, by noting a significant decrease in the Ocean’s uptake of CO2, with consequent damage to Earth’s ecosystems, which in turn has traceable repercussions on the Arctic Ocean and then from the Arctic to the Planet Earth.

In July 2020, the European External Action Service of the European Commission launched a public consultation on the way forward for the European Union’s Arctic policy. The consultation was held to re-examine the role of the EU in Arctic affairs, to revise the priorities of the current Joint Communication on an integrated European Union policy for the Arctic and the actions thereunder, and to identify possible new policy areas to be developed.

At LANDMARC, we are developing methods and instruments that non-researchers can use to reliably estimate how different land-use practices contribute to climate change mitigation. In our view, this can only be done by bringing in local knowledge at every stage of the research process. Here’s why.

Rather than trying to plant as many trees as possible, research coming out of the LANDMARC project suggests that it might be better to focus on planting fewer trees and managing them well, in a way that’s good for the underlying soil.

Air pollution is a growing concern that continues to strongly affects cities worldwide, posing significant threats to both human health and the environment. Nature based solutions is an innovative approach that harness the power of nature and its inherent ability to filter, absorb and mitigate pollutants. In the frame of the Upsurge project, different NBS are being implemented to study their benefits with a focus on air quality and climate remediation.

This article gives an overview of the recent advances on the interactive modelling of ice sheet dynamics in Earth System Models, and the implications for reducing the uncertainty of sea-level rise projections, especially when considering multi-centennial timescales of changes or low-likelihood high-impact scenarios.

The understanding of nature-based negative emission solutions often focuses on their mitigation potential, thus as means for reaching carbon neutrality by 2050. However, this is only one small part of the whole picture; these techniques represent a more sustainable model that brings many environmental benefits in the long term.

In this article, we provide an overview of current understanding of the land-to-ocean carbon fluxes. We describe the new conceptual model of the land-to-ocean aquatic continuum (proposed by Regnier et al, 2022, Nature), as well as ongoing work to include this new knowledge in Earth System Models.
