Everything we've published on Paleoclimate: articles, news, opinion and video.
Three researchers have used chemical traces of algae buried in Arctic seabed mud to judge which climate models to trust on winter sea ice, and report that doing so narrows the uncertainty around the…
A drought, in the usual telling, arrives with heat. The reservoirs fall, the air bakes, and the two feed each other. Tree rings from slow-growing pines high in the southern Colorado Rockies now say…
A study from Lanzhou University reports that whether land has grown wetter or drier since the coldest point of the last ice age has depended on latitude, and projects that continued warming is likely…
About 2,000 billion metric tons of snow settle on the Antarctic ice sheet in an average year, and nothing else adds to it. Everything else that happens to the ice sheet takes mass away. So when the…
A team led by researchers at Université Paris-Saclay has dated the iron-rich crusts that cap a plateau in northern Malawi, finding a continuous span of mineral ages running from 397 million years…
Researchers at the Chinese Academy of Sciences have put a long-term number on something geological carbon budgets usually leave out: how much carbon dioxide the world's dry lands pull from the air as…
Two companion papers published in Nature on Sept. 9, 2026, describe fossils, stone tools and animal bones from Bianfu Cave in Yunnan Province, southwestern China. The authors attribute the material…
Sunlight-driven chemistry in the top few meters of exposed Antarctic ice appears to change the greenhouse gases trapped inside it, Giyoon Lee and Jinho Ahn of Seoul National University and colleagues…
Coral skeletons from a Marshall Islands atoll have yielded a monthly-resolution temperature record spanning three windows of the past 1,500 years, and the comparison suggests that Central Pacific El…
The Hengduan Mountains run north to south along the eastern edge of Tibet, a corrugation of steep ridges and deep river gorges that packs alpine meadow, conifer forest and subtropical valley within a…
On the satellite maps that glaciologists have relied on for four decades, the ice streams of West Antarctica look fixed. Rivers of ice hundreds of kilometers long slide toward the Ross Sea between…
Coral skeletons from the Galápagos Islands carry a record of ocean temperature stretching back 1,000 years. Their chemistry shows a large recent increase in year-to-year temperature swings in the…
