Russian scientists develop method to study reaction of Siberian forests to global warming

TASS · · 437 words

Russian scientists are testing a method to track historical temperature changes in Siberian forests by analyzing the blue light reflected from the annual rings of larch trees. The study aims to provide a simpler, less time-consuming alternative to traditional tree-ring density and width measurements to monitor the impacts of global warming in the Arctic and mountainous regions.
