Forest emissions, wildfires explain why ancient Earth was so hot
The release of volatile organic compounds from Earth's forests and smoke from wildfires 3 million years ago had a far greater impact on global warming than ancient atmospheric levels of carbon dioxide, according to a new study by researchers at the Yale School of Forestry & Environmental Studies. The research provides evidence that dynamic atmospheric chemistry played an important role in past warm climates, underscoring the complexity of climate change and the relevance of natural components.

Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from the atmosphere. The results are now published in Biogeosciences, an open-access journal of the European Geosciences Union. (2014-01-23)

Acid raid, ozone depletion contributed to ancient extinction
Around 250 million years ago, at the end of the Permian period, there was a mass extinction so severe that it remains the most traumatic known species die-off in Earth's history. Some researchers have suggested that this extinction was triggered by contemporaneous volcanic eruptions in Siberia. New results show that the atmospheric effects of these eruptions could have been devastating. (2013-11-22)

Pre-industrial rise in greenhouse gases had natural and anthropogenic causes
For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere -- from about 5,000 years ago to the start of the industrial revolution -- were triggered by natural causes or human activities. A new study, published Friday in the journal Science, suggests the increase in methane likely was caused by both. (2013-11-21)

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 the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins. The results suggest that atmospheric oxygen was considerably lower in the Earth's geological past than previously assumed. This new study questions some of the current theories about the evolution of climate and life, including the causes for the gigantism of dinosaurs. (2013-11-18)

How pigeons may smell their way home
Homing pigeons are extraordinary navigators, but how they find their way home is still debated. To navigate, birds require a 'map' (to tell them home is south, for example) and a 'compass' (to tell them where south is), with the sun and Earth's magnetic field being the preferred compass systems. A new paper shows that the information pigeons use as a map is available in the atmosphere: odors and winds help them find home. (2013-11-05)

Alternative to antibiotics
As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universit├Ąt. Cold atmospheric-pressure plasmas attack the prokaryote's cell envelope, proteins and DNA. (2013-10-01)

Climate change: Fast out of the gate, slow to the finish the gate
Research has focused on the amount of global warming resulting from increased greenhouse gas concentrations. But there has been relatively little study of the pace of the change following these increases. A new study concludes that about half of the warming occurs within the first 10 years after an instantaneous step increase in atmospheric CO2 concentration, but about one-quarter of the warming occurs more than a century after the step increase.

First-time measurements in Greenland snowpack show a drop in atmospheric co since 1950s
A first-ever study of air trapped in the deep snowpack of Greenland shows that atmospheric levels of carbon monoxide (CO) in the 1950s were actually slightly higher than what we have today, not lower as has been predicted by computer models. And improved combustion technology has been linked to the lower CO levels. (2013-09-17)

Probing methane's secrets: From diamonds to Neptune
Hydrocarbons from the Earth make up the oil and gas that heat our homes and fuel our cars. The study of the various phases of molecules formed from carbon and hydrogen under high pressures and temperatures, like those found in the Earth's interior, helps scientists understand the chemical processes occurring deep within planets, including Earth. New research hones in on the hydrocarbon methane (CH4), because its behavior under the conditions found in planetary interiors is poorly understood. (2013-09-12)
