Changes in Earth’s crust caused oxygen to fill the atmosphere

Scientists have long wondered how Earth's atmosphere filled with oxygen. UBC geologist Matthijs Smit and research partner Klaus Mezger may have found the answer...

Early Earth had a hazy, methane-filled atmosphere

More than 2.4 billion years ago, Earth's atmosphere was inhospitable, filled with toxic gases that drove wildly fluctuating surface temperatures. Understanding how today's world...

Study opens new questions on how the atmosphere and oceans formed

A new study led by The Australian National University (ANU) has found seawater cycles throughout Earth's interior down to 2,900km, much deeper than previously...

Fossil fuel formation: Key to atmosphere’s oxygen?

For the development of animals, nothing -- with the exception of DNA -- may be more important than oxygen in the atmosphere. Oxygen enables the...

Earth’s ‘technosphere’ now weighs 30 trillion tons

An international team led by University of Leicester geologists has made the first estimate of the sheer size of the physical structure of the...

Scientists probe underground depths of Earth’s carbon cycle

Understanding how carbon dissolves in water at the molecular level under extreme conditions is critical to understanding the Earth's deep carbon cycle—a process that...

Pollution emitted near equator has biggest impact on global ozone

Since the 1980s, air pollution has increased worldwide, but it has increased at a much faster pace in regions close to the equator. Research...

Megadrought risks in southwest U.S. soar as atmosphere warms

As a consequence of a warming Earth, the risk of a megadrought -- one that lasts more than 35 years -- in the American...

Ice cores reveal a slow decline in atmospheric oxygen over the...

Princeton University researchers have compiled 30 years of data to construct the first ice core-based record of atmospheric oxygen concentrations spanning the past 800,000...

Soil will absorb less atmospheric carbon than expected this century, study...

By adding highly accurate radiocarbon dating of soil to standard Earth system models, environmental scientists from the University of California, Irvine and other institutions...
