Minerology on Mars points to a cold and icy ancient climate

The climate throughout Mars' early history has long been debated -- was the Red Planet warm and wet, or cold and icy? New research...

Land rising above the sea 2.4 billion years ago changed planet...

Chemical signatures in shale, the Earth's most common sedimentary rock, point to a rapid rise of land above the ocean 2.4 billion years ago...

Scientists find new evidences of the megaflood that ended the Messinian...

A study conducted by an international team of scientists has found new evidence supporting the hypothesis of a mega-flood occurring during the Zanclean period,...

Mountain erosion may add CO2 to the atmosphere

Scientists have long known that steep mountain ranges can draw carbon dioxide (CO2) out of the atmosphere -- as erosion exposes new rock, it...

New source of global nitrogen discovered

For centuries, the prevailing science has indicated that all of the nitrogen on Earth available to plants comes from the atmosphere. But a study...

Sinking land will exacerbate flooding from sea level rise in Bay...

Hazard maps use estimated sea level rise due to climate change to determine flooding risk for today's shoreline, but don't take into account that...

Desertification and monsoon climate change linked to shifts in ice volume...

The East Asian summer monsoon and desertification in Eurasia is driven by fluctuating Northern Hemisphere ice volume and global sea level during the Ice...

New Method Unearths Climate Data from Ancient Soils

In Scientific Reports today, UConn researchers report a novel approach to reconstructing ancient climates using analyses of organic compounds in sediments and soils. This method...

Storm waves can move boulders we thought only tsunamis had the...

It's not just tsunamis that can change the landscape: storms shifted giant boulders four times the size of a house on the coast of...

Hidden ‘rock moisture’ could be key to understanding forest response to...

Research conducted by The University of Texas at Austin and University of California, Berkeley has found that a little-studied, underground layer of rock can...

Life under extreme drought conditions

The core region of the Atacama Desert in South America is one of the most arid places on earth. Sometimes it is raining only...

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...
