Major Drought in Middle Ages Could Have Parallels to Climate Change Today

The transition from the Medieval Warm Period to the Little Ice Age was apparently accompanied by severe droughts between 1302 and 1307 in Europe; this preceded the wet and cold phase of the 1310s and the resulting great famine of 1315-21.

Volcanic Eruptions Directly Triggered Ocean Acidification During Early Cretaceous

Around 120 million years ago, the earth experienced an extreme environmental disruption that choked oxygen from its oceans.

Climate Change Caused Demise of Central Asia’s River Civilizations, Not Genghis Khan

A new study challenges the long-held view that the destruction of Central Asia's medieval river civilizations was a direct result of the Mongol invasion in the early 13th century AD.

Newly Discovered Fossils Prove ‘Shangri-La’-Like Ecosystem in Central Tibet

Despite decades of investigation, Tibet's ancient topography and its role in climatic and biotic evolution remain speculative due to a paucity of quantitative surface height measurements through time and space, and sparse fossil records.

Cahokia Study Reveals Impacts of Climate Change on Human History

Water and air are highly mutable resources that exist in a myriad of physical states and dimensions, and due to their affectivity, these entities participate in a multitude of interactions capable of sustaining life, transforming environments, and shaping human behavior.

Archipelago in Ancient Doggerland Survived Storegga Tsunami 8,000-Years-Ago

Doggerland, dubbed “Britain’s Atlantis” is a submerged landmass beneath what is now the North Sea, that once connected Britain to continental Europe.

Transition to Feudal Living in 14th Century Impacted Local Ecosystems

The transition from tribal to feudal living, which occurred throughout the 14th century in Lagow, Poland had a significant impact on the local ecosystem, according to a study published in Scientific Reports.

How a Greenhouse Catastrophe Killed Almost All Life

Earth's history knows catastrophes which are unimaginable for humans. For example, around 66 million years ago an asteroid impact marked the end of the dinosaur era.

Past Tropical Forest Changes Drove Megafauna and Hominin Extinctions

Researchers have found that the loss of these grasslands was instrumental in the extinction of many of the region's megafauna, and probably of ancient humans too.

Ice Discharge in North Pacific Set Off Series of Climate Events During Last Ice Age

Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth's climate during the last ice age, new research published online today in Science reveals.

The Testimony of Trees: How Volcanic Eruptions Shaped 2000 Years of World History

Researchers have shown that over the past two thousand years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change.

Sea Ice Triggered the Little Ice Age

A new study finds a trigger for the Little Ice Age that cooled Europe from the 1300s through mid-1800s, and supports surprising model results suggesting that under the right conditions sudden climate changes can occur spontaneously, without external forcing.
