Haircare ingredients could hold key to reducing CO2 emissions

By - March 24, 2010 1 Picture
New York-based scientists believe that materials closely resembling ingredients found in hair-conditioning shampoos and fabric softeners might be used to “scrub” carbon dioxide (CO2) from coal-burning emissions. These aminosilicones show potential as a less expensive and more efficient alternative to current technologies with tests resulting in removal of up more than 90 percent of CO2 from simulated flue gas.

Brighter, whiter clouds could fight global warming

By - February 22, 2010 1 Picture
Scientists in the US have been cloud-spotting over shipping lanes and have noticed something more interesting than teddy-bear shapes and faces. They have detected that rising steam from passing ships has caused brightening in the clouds which they theorize alters the reflectivity of the cloud and prevents the energy from reaching the Earth. They propose that if this could be achieved artificially via geoengineering it could be an effective defense against global warming. Read More

Computer modeling indicates white roofs may be a cool idea

By - January 28, 2010 1 Picture
Previous studies have indicated that painting the roofs of buildings white could be a low tech way to reduce global warming by reflecting the sun’s rays back into space. Now the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide has added more weight to such a proposal indicating that painting every roof in a city entirely white could cool the world’s cities by an average of about 0.7 degrees Fahrenheit or 0.4 degrees Celsius.

Healing of ozone hole could accelerate global warming

By - January 26, 2010 1 Picture
You'd think the healing of the hole in the ozone layer would be good news, but it seems that although every cloud is said to have a silver lining, they also have a gray one as well. The Antarctic ozone hole was once regarded as one of the biggest environmental threats, but researchers now argue that the ozone hole over Antarctica helped to shield this region from carbon-induced warming over the past two decades and its repair could actually increase warming in the southern hemisphere.

U.S. Trademark Office fast tracking ‘green’ patents

By - December 13, 2009 1 Picture
Recognizing there’s now a sense of urgency in saving the planet, the U.S. Commerce Department’s Patent and Trademark Office (USPTO) will pilot a program to accelerate the examination of certain “green” technology patent applications. According to the USPTO the move is designed to “accelerate development and deployment of green technology, create green jobs, and promote U.S. competitiveness in this vital sector.” Read More

Are EVs risking or saving the planet?

“Electric cars should be rewarded for their energy efficiency, not for moving emissions from exhaust pipes to powerstation chimneys” says the UK's Environmental Transport Association (ETA). In a report titled "How to avoid an electric shock - Electric cars: from hype to reality", the ETA has taken a close look at electric-powered vehicles (EVs) and their associated technologies. In what could be a shock to some commuters – and governments - the report states that EVs could potentially speed climate change, rather than reduce it, and might not be as good for the planet as some of the spin suggests. Simply put, it’s not necessarily the cars themselves that will cause the damage, but the way the electricity is generated to power them and how often we drive them. For instance, EVs powered by “green energy” - wind or solar - are obviously superior, but if the electricity comes from coal, hybrids perform better. Read More

Further doubts atmospheric umbrella will save marine environments

By - June 18, 2009 1 Picture
We recently looked at problems with a last resort solution to counteract global warming by artificially shading the Earth from sunlight by injecting sulphur or small, reflective particles into the upper atmosphere. Now a new study from the Carnegie Institution has thrown further doubt on the effectiveness of such a proposal. Although it may lower the planet’s temperature by a couple of degrees, it would do little to stop the acidification of the world’s oceans that threatens coral reefs and other marine life. Read More

Playing roulette with the climate – everybody loses

By - May 22, 2009 2 Pictures
Research carried out by the MIT's Center for Global Change Science has predicted that global warming will be roughly double previous estimates – and could be even worse than that. While a major 2003 study indicated a median projected increase in earth surface warming of 2.4 degrees Celsius, the new study, which takes into account possible changes in human activities, points to a median probability of surface warming of 5.2 degrees Celsius by 2100 unless drastic action is taken.
