What causes an ice age to end?

New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth's axis...

Study points to one cause for several mysteries linked to breathable...

Earth's breathable atmosphere is key for life, and a new study suggests that the first burst of oxygen was added by a spate of...

New Earth mission will track rising oceans into 2030

Earth's climate is changing, and the study of oceans is vital to understanding the effects of those changes on our future. For the first...

How sulfur helped make Earth habitable before the rise of oxygen

Mapping the bonds and vibrational modes of molecules containing sulfur isotopes is helping to shed light on the chemical reactions that took place in...

A new study shows the evolution and changes of the vegetation...

"Mauritia flexuosa" is the most widespread plant in the Orinoco Delta, in north-western Venezuela. This has not always been the case in the past....

Underwater glacial melting is occurring at higher rates than modeling predicts

Researchers have developed a new method to allow for the first direct measurement of the submarine melt rate of a tidewater glacier, and, in...

Plankton as a climate driver instead of the sun?

Fluctuations in the orbital parameters of the Earth are considered to be the trigger for long-term climatic fluctuations such as ice ages. This includes...

Earliest life may have arisen in ponds, not oceans

Primitive ponds may have provided a suitable environment for brewing up Earth's first life forms, more so than oceans, a new MIT study finds. Researchers...

More CO2 than ever before in 3 million years, shows unprecedented...

CO2 greenhouse gas amounts in the atmosphere are likely higher today than ever before in the past 3 million years. For the first time,...

Study Looks to Iron from Microbes for Climate Help

Distributing iron particles produced by bacteria could "fertilize" microscopic ocean plants and ultimately lower atmospheric carbon levels, according to a new paper in Frontiers. "It...

Large volcanic eruptions can alter hurricane strength and frequency

A new study led by Lamont-Doherty Earth Observatory researcher Suzana Camargo and Université du Québec à Montréal's Francesco Pausata provides deeper insight into how...

Tectonics in the tropics trigger Earth’s ice ages

Over the last 540 million years, the Earth has weathered three major ice ages -- periods during which global temperatures plummeted, producing extensive ice...

Rescuing geologic and climate records

Scattered throughout the Philippines are many caves containing precious geological formations that hold key information about past climate. But due to local quarrying, some...

The deep Southern Ocean is key to more intense ice ages

Over the last million years, ice ages have intensified and lengthened. According to a study led by the University of Bern, this previously unexplained...

As sea level rises, wetlands crank up their carbon storage

Some wetlands perform better under pressure. A new study revealed that when faced with sea-level rise, coastal wetlands respond by burying even more carbon...

Alaska forest fires over past 450 years

In a recent study, University of Montana researchers explored the ways forest succession and climate variability interacted and influenced fires in Alaska's boreal forests...

Unusual microbes hold clues to early life

A new study has revealed how a group of deep-sea microbes provides clues to the evolution of life on Earth, according to a recent...

Researchers help define Southern Ocean’s geological features

New data collected by University of Wyoming researchers and others point to a newly defined mantle domain in a remote part of the Southern...

Researchers unearth an ice age in the African desert

A field trip to Namibia to study volcanic rocks led to an unexpected discovery by West Virginia University geologists Graham Andrews and Sarah Brown. While...

Fault lines are no barrier to safe storage of CO2 below...

Carbon dioxide emissions can be captured and securely stored in underground rocks, even if geological faults are present, research has confirmed. There is minimal possibility...
