On that core, they counted 2,400 tree rings and estimated the additional age using modeling. According to Science magazine, the tree was estimated to be 5,484 years old.

And the tree ring building is round, to architecturally represent a tree. It felt like a perfect merging of architecture, shape, sound, data, wood material and science.

Subsequent coring and analysis of Methuselah by Tom Harlan at the Laboratory of Tree-Ring Research dated the innermost tree ring to 2491 BCE. Thus, in 2023 Methuselah’s age would be 4,514 years old.

The tree-core samples themselves came from Bighorn Basin, a mountain-encircled plateau region in north-central Wyoming about 500 miles from Boulder. Waddle collected some of the tree cores herself in ...

A look inside a rare, 400-year-old tree found in the Lorneville area of Saint John offers a microscopic glimpse at the ...

Tree rings in the Amazon reveal intensifying rainfall extremes, with wetter wet seasons and drier dry seasons, reshaping ...

The innermost rings on Schulman’s core samples are extremely suppressed and partly eroded, making dating difficult. The oldest extracted ring from Methuselah might be from 2490 or 2555 B.C.E.

Then in 2010, another researcher restarted the project, finding one core that seemed to suggest a still-living tree might be 5,062 years old. But that researcher died before the work was complete ...

In this core sample, a ring of wood from that year never had a chance to grow. A decade of relatively dry years followed. There was little rain in 1579, and the next year even less.

Scientists can, with reasonable certainty, use tree rings to draw conclusions about individual years in the Northern Hemisphere (536 CE was the coldest, for instance, likely because of volcanic ...
