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...

During the Mid-Holocene sea surface temperatures were also considerably warmer despite CO2 levels only reaching ~265 ppm. Yet at that time sea levels were about 2 or more meters higher than they are today according to an...

In a study published in Nature Communications, the researchers show that an organic molecule often found in high-latitude ocean sediments, known as tetra-unsaturated alkenone (C37:4), is produced by one or more previously...

813 years of annual river discharge at 62 stations, 41 rivers in 16 countries, from 1200 to 2012. That is what researchers at the Singapore University of Technology and Design (SUTD) produced after two years of research in...

Two recently published studies confirm that the climate thousands of years ago was as warm or warmer than today’s – a fact disputed by some believers in the narrative of largely human-caused global warming...

Glaciers in the Ötztal Alps in Austria are currently melting and may be lost within two decades, but this might not be the first time humans have seen this kind of change...

A wealth of new research in glacier and sea ice extent show modern Iceland is 2-4°C colder than all of the last 8000 years except for a slightly colder late 19th century...

Antarctica's next deep ice core, drilling down to ice from 130,000 years ago, will be carried out by a multi-institutional U.S. team at Hercules Dome, a location hundreds of miles from today's coastline and a promising site...

Guest essay by H. Sterling Burnett, originally published on ClimateRealism.com Archaeologists have published a new paper in The Holocene, DOI: 10.1177/0959683620972775 that confirms what previous research has...

Guest “How did they miss this?” by David Middleton PRESS RELEASE / OCTOBER 26, 2020 AUSTRALIAN SCIENTISTS DISCOVER 500 METER TALL CORAL REEF IN THE GREAT BARRIER REEF–FIRST TO BE DISCOVERED IN OVER 120 YEARS...

During the last Ice Age about 20,000 years ago, iron-containing dust acted as a fertilizer for marine phytoplankton in the South Pacific, promoting CO2 sequestration and thus the glacial cooling of the Earth...

Guest “you can’t fix stupid” by David Middleton The sad thing is that this was apparently written by two geoscience professors. The Arctic hasn’t been this warm for 3 million years – and that foreshadows...

Guest “geological perspective” by David Middleton This is sort of a sequel yesterday’s post: Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters...
