By observing the tree-ring-like growth records present in volcanic crystals, geologists are able to track volcanic activity and reconstruct the steps leading up to eruptions.

Until recently, little was known about how memory functions in trees which experience decades, even centuries, of shifting environmental pressures.
Tree-rings unlock 195 years of past climate in the Gaspésie mountains.
From whale earwax to bird feathers, almost all organisms keep a record of their existence.
On a regional scale, global warming exceeded the Paris agreement’s upper climate target in the northern hemisphere.
Most of us just take it for granted. But bark is one of the most complex parts of a tree and has many different jobs to do.
A longer growing season for trees, due to global warming, does not necessarily lead to an increase in wood production.
Medieval monks recorded hundreds of lunar eclipses. Centuries later, their descriptions are helping scientists unravel the role of volcanoes in historical climate change.
Evidence in Earth’s natural archives, from tree rings to seafloor sediments, points to one trend. Some climate models suggest another.
The findings have repercussions today: it is clear that slow-growing animals will be the most vulnerable to extinction amid shifting climates.
Half a dozen times in the past 10,000 years, enigmatic ‘Miyake events’ have showered Earth with cosmic rays.
Tree rings are ‘nature’s weather stations’ and reveal far more of the Daly River’s history than scientific records can.
Tree rings carry a wealth of information, which can be used to uncover climate data from hundreds of years ago.
Our research found that in 700 years, the 20th century was the wheatbelt’s wettest. This means all our drought predictions are skewed.
Trees may be more resilient to future dry spells than scientists first thought.
Study using tree ring data and climate projections shows that buildup of CO2 will not benefit most northern forests and that growth rates will actually fall.
Multiple times over the centuries, climate issues caused Pueblo farming to collapse, taking the establishment down with it. New research suggests there are parallels with American inequalities today.
In an attempt to better understand hurricanes, researchers recreate hundreds of years of hurricane records with Spanish shipwreck logs and tree ring data.
Forests take longer than expected to rebound from droughts, diminishing their role as global carbon sinks.
After unifying the Mongols, Genghis Khan led his army from Northern Mongolia in 1211 to the Caspian Sea in 1224, forging the largest contiguous land empire in history. For centuries, common wisdom held…
