Data availability and temporal resolution make it challenging to unravel the anatomy (duration and temporal phasing) of the Last Glacial abrupt climate changes...

Bern's ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years...

"As a piece of work showing what you can do with poo, this study breaks new ground," said Michael Bird, a researcher in environmental change in the tropics at James Cook University in Queensland, Australia, who was not involved...

Guest “damning with faint praise” by David Middleton Kaufman, Mckay, Routson, et al., 2020 In my previous post, I noted a “funny pattern” in the latest Holocene climate reconstruction (Kaufman,…

Guest “A funny thing happened on the way to the Anthropocene” by David Middleton I’ve been studying a recent Holocene climate reconstruction (Kaufman, D., McKay, N., Routson, C. et al., 2020)……

The plant matter stuff reported in PNAS is obviously true. So Greenland did mostly melt about 1 mya; otherwise those plants could not have existed there then, however briefly. But this ‘climate fact’ ignores two big ‘other...

9300-year old vegetation remnants found under receding glaciers in Northern Sweden show that the trees once grew where tundra exists today, meaning it was warmer.

9300-year old vegetation remnants found under receding glaciers in Northern Sweden show that the trees once grew where tundra exists today, meaning it was warmer.

The long-standing mystery is called the "Holocene temperature conundrum," with some skeptics contending that climate model predictions of future warming must be wrong...

"By combining the sediment analyses with results from our computer simulation, we can now precisely understand the climatic processes at work to explain the drastic changes in North African environments over the past 160,000...

Predictions of future climate change require a clear and nuanced understanding of Earth's past climate. In a study published today in Science Advances, University of Hawai'i (UH) at Mānoa oceanographers fully reconciled...

Scientists have discovered the DNA of some 2,100 kinds of plants and 180 animals — including American horses and woolly mammoths – dating to thousands of years after their supposed extinction.

Previously hidden under a Swiss glacier, a 10,800-year old tree trunk was discovered and tells us the Alps were much warmer in the early Holocene than today.

By Andy May In my last post, it was suggested that Michael Mann’s 2008 reconstruction (Mann, et al., 2008) was similar to Moberg’s 2005 (Moberg, Sonechkin, Holmgren, Datsenko, & Karlen,…

A current study of the University of Bonn (Germany) now sheds light on this: It indicates that the collapse of coastal ecosystems was caused by climatic changes...
