Extinct lakes of the American desert west

The vestiges of lakes long extinct dot the landscape of the American desert west. These fossilized landforms provide clues of how dynamic climate has...

How seafloor weathering drives the slow carbon cycle

A previously unknown connection between geological atmospheric carbon dioxide cycles and the fluctuating capacity of the ocean crust to store carbon dioxide has been...

Global warming – we have lessons to learn from the Pliocene...

Carbon levels around 3 million years ago were similar to those of today and temperatures were even warmer. If something so significant is mirrored...

Primordial oceans had oxygen 250 million years before the atmosphere

Research by a University of Minnesota Duluth (UMD) graduate student Mojtaba Fakhraee and Associate Professor Sergei Katsev has pushed a major milestone in the...

Heat loss from the Earth triggers ice sheet slide towards the...

Greenland's ice sheet is becoming smaller and smaller. The melting takes place with increased strength and at a speed that no models have previously...

World’s oldest known oxygen oasis discovered

In the Earth's early history, several billion years ago, only traces of oxygen existed in the atmosphere and the oceans. Today's air-breathing organisms could...

Oldest ice core ever drilled outside the polar regions

The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age -- more than 600,000 years...

Decline in atmospheric carbon dioxide key to ancient climate transition

A decline in atmospheric carbon dioxide (CO2) levels led to a fundamental shift in the behaviour of the Earth's climate system around one million...

Climate change could increase volcano eruptions

Shrinking glacier cover could lead to increased volcanic activity in Iceland, warn scientists. A new study, led by the University of Leeds, has found that...

A sub-desert savanna spread across Madrid 14 million years ago

The Central Iberian Peninsula was characterised by a very arid savanna during the middle Miocene, according to a study led by the Complutense University...

When continents break it gets warm on Earth

The concentration of carbon dioxide (CO2) in the atmosphere determines whether the Earth is in greenhouse or ice age state. Before humans began to...

Changing climate to bring more landslides on logged land

Washington State University researchers say landslides on logged forests will be more widespread as the Northwest climate changes. In a study modelled on clear-cut lands...

Heat Source Under West Antarctica

A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some...

Dinosaur-killing asteroid impact cooled Earth’s climate more than previously thought

The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought, according to...

Future volcanic eruptions could cause more climate disruption

Major volcanic eruptions in the future have the potential to affect global temperatures and precipitation more dramatically than in the past because of climate...

Late Triassic terrestrial ecosystem changes

The Norian Chinle Formation in the Southwestern United States provides a snapshot into an ancient terrestrial ecosystem with its famous petrified tree trunks and...

The oceans were colder than we thought

A team of researchers has discovered a flaw in the way past ocean temperatures have been estimated up to now. Their findings could mean...

Scientists use seismic waves to measure tornado intensity

Seismic waves generated by tornadoes when they touch down could be used to measure a twister's intensity, according to a new study. The new research...

Yellowstone Spawned Twin Super-Eruptions that Altered Global Climate

A new geological record of the Yellowstone supervolcano's last catastrophic eruption is rewriting the story of what happened 630,000 years ago and how it...

Ice sheets may melt rapidly in response to distant volcanoes

Volcanic eruptions have been known to cool the global climate, but they can also exacerbate the melting of ice sheets, according to a paper...
