New research provides a 200-year reconstruction of interannual rainfall in the Amazon basin using oxygen isotopes preserved in tree rings in Ecuador and Bolivia.
Driftwood floats thousands of kilometers from Siberia to Iceland, but it may drift no longer by 2060 due to climate change.
Volcanoes, heat waves, and tree rings – getting the seasonal story straight – a new study finds that volcanic fog lowered summer tree ring density despite the heat.
Tree rings confirm that in northern Australia, the past 40 years have experienced more rain than any similar length of time in the past 600 years.
An international group of researchers may have found a way to better account for carbon storage in forests.
Tree core chemistry can explain what happened before Mount Etna’s 2002 eruption and suggests that trees could play a role in rebuilding past eruptions.
Researchers look to carbon isotopes and cell-level wood anatomy to understand how seismic-induced changes in water availability affect tree growth.
Trees tell of a wetter past along the Brahmaputra River and, combined with climate modeling, suggest heightened future flood risks in one of the world’s most densely populated areas.
Mass spectroscopy of tree ring material indicates a sharp, single-year rise in carbon-14 concentrations consistent with an extreme solar energetic particle event that occurred around 5410 BCE.
