Analysis of Tree-Ring Records Suggests Current Climate is Warmer than Medieval Period
An analysis of tree-ring records from Fennoscandia, a region in northern Europe, spanning the past 1,170 years, reveals that the current climate may be substantially warmer than during the medieval period. This contradicts previous research and highlights the large uncertainties that persist in climate models and proxies at regional scales, especially prior to AD 1400.
Tree-Rings as Indicators of Climate Change
Tree-rings serve as valuable indicators of climate change over long periods of time and can track the amplitude of climate extremes. However, there is currently a discrepancy between tree-ring data and climate models when it comes to the medieval climate. While models suggest that the medieval period was cooler compared to the present, tree-ring data often suggest the opposite.
Precise Record of Past Climate in Fennoscandia
To address this discrepancy and provide a more precise record of the past climate in Fennoscandia between AD 850 and 2019, researchers conducted an analysis of 1,170 years of tree ring data. This analysis was based on approximately 50 million wood cell measurements from 188 living and dead Scots pine trees.
By focusing on individual wood cells, known as tracheid cells, the researchers were able to collect more accurate data compared to conventional tree-ring data. The findings of this study indicate that the Fennoscandian climate is significantly warmer today than during the medieval period.
Implications for Sustainable Development Goals
This research has important implications for the Sustainable Development Goals (SDGs), particularly SDG 13: Climate Action. The findings support the argument that anthropogenic climate change is contributing to increased temperatures in the Fennoscandia region.

- SDG 15: Life on Land
Conclusion
The analysis of tree-ring records from Fennoscandia provides valuable insights into the climate of the medieval period and its comparison to the present. The discrepancy between tree-ring data and climate models highlights the need for further research and improved modeling techniques. This study contributes to our understanding of climate change and its impact on specific regions, supporting the global efforts towards achieving the Sustainable Development Goals.
SDGs, Targets, and Indicators
-
SDG 13: Climate Action
- Target 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters
- Target 13.2: Integrate climate change measures into national policies, strategies, and planning
- Target 13.3: Improve education, awareness-raising, and human and institutional capacity on climate change mitigation, adaptation, impact reduction, and early warning
- Target 13.a: Implement the commitment undertaken by developed-country parties to the United Nations Framework Convention on Climate Change to a goal of mobilizing jointly $100 billion annually by 2020 from all sources to address the needs of developing countries in the context of meaningful mitigation actions and transparency on implementation and fully operationalize the Green Climate Fund through its capitalization as soon as possible
- Target 13.b: Promote mechanisms for raising capacity for effective climate change-related planning and management in least developed countries and small island developing States, including focusing on women, youth, and local and marginalized communities
The article discusses the current climate being substantially warmer than during the medieval period, which is directly related to climate change. This aligns with SDG 13, which aims to take urgent action to combat climate change and its impacts.
