A new study published in the journal Science by an international team reveals that historical fluctuations in atmospheric CO2 levels and the subsequent alterations in climate…
A recent study led by Macquarie University earth scientist Dr. Chunfei Chen sheds new light on geological processes from up to three billion years ago…
Over the past 66 million years, two major climate events have shaped the climate system, dividing the period into two distinct climate eras. An analysis…
Paleoclimate evidence indicates that roughly 1.1 million years ago, there was a significant drop in temperature in southern Europe. This climate shift likely led to…
A new study connects seawater chemical shifts to volcanic activity and climate. Sea salt hides a secret: tiny droplets of the seawater from which it…
Recent research reveals that volcanic activity 56 million years ago emitted a higher amount of methane than previously estimated. Approximately 55 million years ago, the…
According to recent findings by Cambridge University researchers, an ancient stalagmite from a Himalayan cave contains evidence of multiple prolonged and severe droughts that may…
Scientists have mapped out oceanic “dead zones” from the Pliocene epoch, when Earth’s temperature was two to three degrees higher than today. This could offer…
A chemical analysis of sediment cores from the North Pacific Ocean reveals a consistent pairing of volcanic ash and hypoxia, a low ocean oxygen interval…
Droughts in the sixth century helped Islam gain ground Extreme dryness aided the collapse of the ancient South Arabian kingdom of Himyar. The journal Science…
Study finds social conditions key to long-term resilience during times of dramatic change. A remote community in Ireland was adaptable enough to persevere through a…
Early Human Habitats Linked to Past Climate Shifts A study published in Nature by an international team of scientists provides clear evidence for a link…
Extreme Heat Led to Episodic Deluges on Hothouse Earth Today, we are experiencing the dramatic impacts that even a small increase in global temperatures can…
A study published in the journal Geology rules out that extreme volcanic episodes had any influence on the massive extinction of species in the late…
A new study led by researchers at Binghamton University, State University of New York found that the Kuroshio Current Extension is sensitive to global climate…
A relatively new way of analyzing tree rings has allowed researchers to reconstruct temperatures in Mongolia since 1269 C.E. The new reconstruction confirms that since…
Researchers observe a “warming bias” over the past 66 million years that may return if ice sheets disappear. It is increasingly clear that the prolonged…
Newly published research from Caltech describes ancient water flows and lakes on Mars, and what this might mean about the ancient climate. We have heard…
