Humble moss helped create our oxygen-rich atmosphere

The evolution of the first land plants including mosses may explain a long-standing mystery of how Earth's atmosphere became enriched with oxygen, according to...

Buried oxygen rose to the occasion as Earth’s early atmosphere formed

Oxygen buried deep underground in minerals may have prompted the churning of Earth's rocky mantle billions of years ago and helped transform the planet's...

Oldest rocks in Australia unlock secrets of the atmosphere

Research into micro-meteorites, meteorites smaller than 2 millimeters, found in Western Australia have shed new light on the make-up of the ancient Earth's atmosphere. The...

Oxygen atmosphere recipe = tectonics + continents + life

Earth scientists from Rice University, Yale University and the University of Tokyo are offering a new answer to the long-standing question of how our...

Study pinpoints timing of oxygen’s first appearance in Earth’s atmosphere

Today, 21 percent of the air we breathe is made up of molecular oxygen. But this gas was not always in such ample, life-sustaining...

Cosmic dust reveals Earth’s ancient atmosphere

Using the oldest fossil micrometeorites -- space dust -- ever found, Monash University-led research has made a surprising discovery about the chemistry of Earth's...

Early Earth’s air weighed less than half of today’s atmosphere

The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles...

Insights into the origins of sodium and other metallic layers in...

Takuo Tsuda, assistant professor, Graduate School of Informatics and Engineering, discusses recent work. The Earth's atmosphere is critical for the existence of mankind. A...

Isotopic memory of atmospheric persistence

Chemical analysis of some of the world's oldest rocks, by an international team led by McGill University researchers, has provided the earliest record yet...

Electromagnetic waves linked to particle fallout in Earth’s atmosphere, new study...

In a new study that sheds light on space weather's impact on Earth, Dartmouth researchers and their colleagues show for the first time that...

Iron toxicity for cyanobacteria delayed oxygen accumulation in early Earth’s atmosphere

Three billion years ago, Earth's atmosphere contained less than 0.0001 percent oxygen. Today's atmosphere has around 20 percent oxygen -- and that is due...

Losing air:New study finds a barrage of small impacts likely erased...

Today's atmosphere likely bears little trace of its primordial self: Geochemical evidence suggests that Earth's atmosphere may have been completely obliterated at least twice...

Modeling sulfur in the Archean atmosphere

A new study has revealed details about the composition of Earth's atmosphere during the Archean eon, which lasted from around 4 billion years ago...

New study suggests more and longer atmospheric stagnation events due to...

A new study conducted by researchers at Stanford University has led to findings indicating that much of the world can expect to have more...

Regional weather extremes linked to atmospheric variations

Variations in high-altitude wind patterns expose particular parts of Europe, Asia and the US to different extreme weather conditions, a new study has shown. Changes...

Atmospheric boundary layer exacerbated mega heat waves

The extreme nature of the heat waves of 2003 in Western Europe and of 2010 in Russia and Eastern Europe even surprised scientists at...

The ups and downs of early atmospheric oxygen

A team of biogeochemists at the University of California, Riverside, give us a nontraditional way of thinking about the earliest accumulation of oxygen in...

Seashells provide million-year-old weather report

New research, published in Earth and Planetary Research Letters, led by scientists from the University of Cambridge, used plankton – tiny bugs, whose shells...

Amber provides new insights into the evolution of the Earth’s atmosphere

An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of Earth's atmosphere of the last 220 million years...

Mars had an oxygen-rich atmosphere four billion years ago

Mars had an oxygen-rich atmosphere more than a billion years before the Earth, say scientists. An examination of meteorites and rocks on the planet...
