Russian scientists have developed a novel method to study how Siberian forests, particularly larch trees, respond to global warming by analyzing the reflected blue light from their annual rings. This technique allows for accurate tracking of temperature changes in remote Arctic regions, where climate change is occurring at an unprecedented rate.
- 01The new method utilizes changes in reflected blue light from tree rings to assess temperature variations.
- 02The research focuses on three main larch species across six regions in Siberia, from the Urals to Yakutia.
- 03The study found that the intensity of reflected blue light varies significantly based on summer temperatures.
- 04Traditional methods of measuring tree ring density and width are time-consuming and require specialized equipment.
- 05The research aims to better understand the impact of climate change on tree growth in the rapidly warming Siberian Arctic.

Russian scientists have introduced an innovative technique to assess how Siberian forests react to global warming by analyzing the reflected blue light from tree annual rings. This method, developed over the past decade, aims to provide a more efficient alternative to traditional methods that measure tree ring density and width. Alberto Arsak, head of the Laboratory for Integrated Studies of Eurasian Forest Dynamics at Siberian Federal University in Krasnoyarsk, emphasized the method's potential for accuracy and applicability across various tree types and large areas. The Russian Arctic is experiencing climate change at a rate much faster than other regions, prompting the need for effective monitoring of tree species' responses to temperature fluctuations. The research team collected wood samples from three larch species in six Siberian regions, measuring annual ring widths and their interaction with blue light. Their findings revealed that the intensity of reflected blue light varies significantly with summer temperatures. This approach allows scientists to track average summer temperature changes and understand the broader impacts of climate change on tree growth in Siberia and the Arctic.
