A 2-billion-year-old chunk of sea salt provides new evidence for the transformation of Earth's atmosphere into an oxygenated environment capable of supporting life as we know it. A sample of 2-bi…
Marine scientists have uncovered evidence of one of the largest floods in Earth's history in the central Mediterranean seafloor. Artistic interpretation of the flooding of the Mediterranean throu…
Engineers working on Britain’s new high speed railway have discovered an ancient, sub-tropical coastline dating back 56 million years. A depiction of what the area would have looked like during the P…
History can tell us a lot about environmental upheaval, say Princeton University historians John Haldon and Lee Mordechai. What is missing in today's debate about climate change is using what we …
Interest in human evolution has stimulated new geological work in the southern rift valley of Kenya. A new Geological Society of America Bulletin article by Anna K. Behrensmeyer and colleagues prese…
The extreme wet and dry periods Mongolia has experienced in the late 20th and early 21st centuries are rare but not unprecedented and future droughts may be no worse, according to an international re…
It may not rank among the all-time greatest dramas, but the history of ice on Greenland has been a source of scientific controversy for more than a decade. Iceberg off the coast of Greenland [Credit:…

The East Asian summer monsoon and desertification in Eurasia is driven by fluctuating Northern Hemisphere ice volume and global sea level during the Ice Age, as shown in a study published in Nature C…
A new NASA study has, for the first time, cut a clear path through a nettlesome problem: accurately measuring a powerful effect on global sea level that lingers from the last ice age. Glacial isostat…
The simple story says that during the last ice age, temperatures were colder and ice sheets expanded around the planet. That may hold true for most of Europe and North America, but new research from …
New research, published in Scientific Reports , has outlined a new methodology for estimating ancient atmospheric water content based on fossil plant leaf waxes. This is the Calatayud-Daroca Basin in…
Fields, streets and cities, but also forests planted in rank and file, and dead straight rivers: humans shape nature to better suit their purposes, and not only since the onset of industrialization. …
A team led by geochemist Dr. Katharina Pahnke from Oldenburg has discovered important evidence that the rise in atmospheric carbon dioxide levels at the end of the last ice age was triggered by chang…
