Tiny new air samplers could aid in climate research

By - April 11, 2012 1 Picture
The monitoring of air quality can be a tricky business. Gases may be blown into the sampling site from another area, they may leak out of an air sample before it can be analyzed, or the sampling container itself may introduce compounds, emitted through off-gassing. If samples are being gathered in remote areas, it can also be difficult getting bulky equipment to and from the sampling site. Now, scientists from Sandia National Laboratories have announced a tiny new type of air sampler, that addresses these and other challenges. Read More

Putting 1 million tonnes of CO2 a mile under Illinois

By - February 23, 2012 3 Pictures
A bold undertaking to store one million metric tonnes (1.1 million short tons) of carbon dioxide in a sandstone reservoir 1.3 miles (2.1 km) below Decatur, Illinois, is well under way. The project began last November, and has so far injected more than 75,000 tons of carbon dioxide, almost one tenth of the target. The University of Illinois, which is leading the Illinois Basin - Decatur Project (IBDP), hopes that the scheme will demonstrate the safety and effectiveness of carbon sequestration, as well as raise public awareness of the process's potential environmental benefits.

Student scheme to protect Future-Manhattan from rising sea levels

By - February 15, 2012 9 Pictures
A pair of students at the University of Pennsylvania have an audacious suggestion should rising sea levels make their presence felt in Manhattan, New York. Their scheme would see the installation of waterproof canopies to the lower stories of skyscrapers. Tingwei Xu and Xie Zhang say their idea has an "irreducible integrity," thanks to the canopies' various functions which, the students say, are each of equal importance. So in addition to keeping water out, these canopies provide additional structural support against lateral forces, provide green or agricultural space, and, judging by the visualizations, provide living and working areas in their own right.

Study finds sunshade geoengineering could improve crop yields

By - January 26, 2012 1 Picture
In the face of potentially catastrophic effects on global food production, some have proposed drastic solutions to counteract climate change such as reflecting sunlight away from the Earth. A new study from the Carnegie Institution for Science examining the effects of sunshade geoengineering has concluded that such an approach would be more likely to improve food security than threaten it.

Newly discovered molecule has potential to offset climate change and cool the planet

By - January 16, 2012 2 Pictures
Researchers claim a newly discovered molecule found in the Earth’s atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.

New material shown to remove CO2 from smokestack effluent and other sources

By - January 5, 2012 1 Picture
In recent years, worries over global climate change caused by excess atmospheric carbon dioxide have led to a number of technologies all aimed at the same thing – capturing human-generated CO2 at the source. These have included the use of things such as edible sponges, molten salts and bacteria, to name just a few. Now, a group of scientists are claiming success with a process that has achieved “some of the highest carbon dioxide removal rates ever reported for humid air” ... and it uses a common and inexpensive polymer.

Construction of USA’s first large-scale industrial carbon capture and storage facility begins

By - August 29, 2011 1 Picture
While some see carbon capture and storage as akin to sweeping CO2 emissions under the carpet, others believe it is a necessary short-term solution in the transition to a clean energy future. Last week, ground was broken on construction of the U.S.'s first large-scale industrial carbon capture and storage (ICCS) facility that aims to demonstrate that CO2 emissions can be stored permanently in deep underground rock formations.

New study highlights the environmental benefits of lab-grown meat

By - July 18, 2011 1 Picture
As a meat lover, it's been hard not to notice the rise in the price of meat at my local supermarket over the last few years. But it’s not just the cost to consumers that is a major concern; it’s the major role that livestock production plays on climate change. While cultured meat, also known as in vitro meat, lab-grown meat and even Frankenmeat, might not sound that appetizing to many meat lovers, a new study carried out by scientists from Oxford University and the University of Amsterdam says that cultured meat would provide substantial environmental benefits.
