Competition not concentration matters when forming cloud-influencing aerosols

Mon, 2015-04-13 14:08
The amount of secondary organic aerosol (SOA) produced from isoprene released by trees as well as the SOA volatility are more accurately tied to interactions with electron-rich, carbon-based chemicals, known as organic peroxy radicals, that compete with nitrogen oxides in reactions.

Burying the climate change problem

Mon, 2015-04-13 10:26
Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. Now, a team of researchers has reviewed the risk assessments for this technology and suggests a lack of knowledge means we should be cautious of turning to this method rather than finding sustainable ways to reduce emissions at their source.

Greatest mass extinction driven by acidic oceans, study finds

Thu, 2015-04-09 14:30
Changes to the Earth's oceans, caused by extreme volcanic activity, triggered the greatest extinction of all time, a study suggests. The amount of carbon added to the atmosphere that triggered the mass extinction was probably greater than today's fossil fuel reserves, the team says. However, the carbon was released at a rate similar to modern emissions. This fast rate of release was a critical factor driving ocean acidification, researchers say.

How unwanted CDs and DVDs could help cut carbon emissions

Wed, 2015-04-08 11:37
Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled. But soon these discarded discs could take on a different role: Curbing the release of greenhouse gases. Scientists report a way to turn the discs into a material that can capture carbon dioxide, a key greenhouse gas, and other compounds.

Ordinary clay can be used for carbon capture

Wed, 2015-04-08 09:03
Carbon capture will play a central role in helping the nations of the world manage and reduce their greenhouse gas emissions. Many materials are being tested for the purpose of capturing carbon dioxide. New results show that ordinary clay can work just as effectively as more advanced materials.

Anesthetic gases raise Earth's temperature (a little) while you sleep

Tue, 2015-04-07 12:42
The gases used to knock out surgery patients are accumulating in the Earth's atmosphere, where they make a small contribution to climate change, report scientists who have detected the compounds as far afield as Antarctica. Like the well-known climate warmer carbon dioxide, anesthesia gases allow the atmosphere to store more energy from the Sun. But unlike carbon dioxide, the medical gases are extra potent in their greenhouse-gas effects, scientists say.

No Red and Blue Divide When it Comes to Renewable Energy Innovation and CO2 Rules

Mon, 2015-04-06 16:56
Much has been made of deep divisions over global warming science in America, but there’s a lot of agreement on steps that could help cut greenhouse gas emissions.

Climate change, plant roots may accelerate carbon loss from soils

Mon, 2015-04-06 16:55
Soil, long thought to be a semi-permanent storehouse for ancient carbon, may be releasing carbon dioxide to the atmosphere faster than anyone thought. In a new study, researchers showed that chemicals emitted by plant roots act on carbon that is bonded to minerals in the soil, breaking the bonds and exposing previously protected carbon to decomposition by microbes.

New evidence shows carbon's importance to ocean life's survival 252 million years ago

Fri, 2015-04-03 23:37
A new study shows for the first time how carbon offered a mode of survival for some ocean life after one of the greatest mass extinctions in the history of Earth.

[Perspective] Defining the epoch we live in

Thu, 2015-04-02 20:00
Human alterations of Earth's environments are pervasive. Visible changes include the built environment, conversion of forests and grasslands to agriculture, algal blooms, smog, and the siltation of dams and estuaries. Less obvious transformations include increases in ozone, carbon dioxide (CO2), and methane (CH4) in the atmosphere, and ocean acidification. Motivated by the pervasiveness of these alterations, Crutzen and Stoermer argued in 2000 that we live in the “Anthropocene,” a time in which humans have replaced nature as the dominant environmental force on Earth (1). Many of these wide-ranging changes first emerged during the past 200 years and accelerated rapidly in the 20th century (2). Yet, a focus on the most recent changes risks overlooking pervasive human transformations of Earth's surface for thousands of years, with profound effects on the atmosphere, climate, and biodiversity.
