Tiny extremophiles give the salty lakes their rosy hue, but over-mining and climate change are threatening their existence.

They used radiocarbon dating, counted tree rings, and measured the width of each ring in the subfossils to investigate how these trees grew in the past. These remains tell a striking story.

By studying the tree rings in the Sainte-Anne River basin, the researchers say they observed a climate-change linked decline in extreme spring river flows and snowpack levels since 1937.

Quebec tree rings dating back nearly 200 years indicate snowpack in the Gaspésie mountains has declined considerably in recent decades, Concordia University researchers suggest.

Trees are natural timekeepers, silently recording the passage of years in their rings, growth patterns, and changing foliage. Their annual rings, visible in cross-sections of trunks, tell stories ...

IDEAS The rings inside trees are beginning to tell a different story If you cut down a tree, you can read in the wood an environmental record. Now climate change is complicating the narrative.

New data on over 1,500 trees across nearly 1,000 sites shows that an existing theory of how individuals within a species will respond to a changing climate might not be true.

Tree rings suggest the Northern Hemisphere summer of 2023 was the hottest in 2,000 years, with temperatures exceeding those of the coldest summer in the same period by 7 degrees Fahrenheit (3.9 ...

Bryan Black discovered that he could build timelines and learn about the climate studying the rings in the bones of fish.

The study part of an emerging field of tree-ring science found the West’s two-decade drought is inextricably linked to rising temperatures ...

What the rings tell us Counting the rings on the sample can tell us the trees' age, but it can also tell us what weather patterns were like each year.
