Over three days in October, 75 sixth graders from Hendricks Elementary visited the Laboratory of Tree-Ring Research and took a deep dive into the world of dendrochronology, building on their classroom learning about tree rings, climate, and water use.

Analyzing tree-ring samples for spikes of naturally occurring radioactive carbon isotopes, a team led by U of A scientists has pinpointed the date of a massive solar particle eruption event that has long eluded researchers.

Climate change is altering the story that trees are telling. Scientists are having to adjust, coming up with new approaches to interpret the changing signal. And yet, as the scientists are shifting their techniques, it may be possible for them to design methods that get even more precise about the past — and in turn will help us better adapt to the future.

With funding from the Department of Energy, U of A researchers are working to revolutionize our understanding of how soil microbes influence climate change.
