Global Warming

Wind farms can cause change in local temperatures (Photo: Gizmag)

The benefits of wind farms in terms of global climate change are well recognized but according to researchers at the University of Illinois they can also affect local climates as well. The researchers observed that the area immediately surrounding a wind farm is slightly warmer at night and slightly cooler during the day compared to the rest of the region. The discovery could allow for strategies to mitigate those effects in areas where they are undesirable, or take advantage of them in others.  Read More

A new report suggests that international efforts to halt the destruction of the ozone layer have been successful. Launched on the UN International Day for Preservation of the Ozone Layer, the report by 300 scientists also provides new information about the net effects on Earth's climate, and also the effects of climate change on the ozone later moving forward.  Read More

Dry water has been found to have several potential environmentally-friendly uses

You know, I’m pretty sure I remember a Far Side cartoon or something, where someone was selling powdered water – “Just add water!” Well, dry water isn’t quite the same thing. It’s 95 percent liquid water, but that water takes the form of tiny droplets each encased in a tiny globe of silica. The resultant substance is dry and granular. It first came to light in 1968, and was used in cosmetics. More recently, a University of Liverpool research team has been looking into other potential uses for the substance. They have found several, but most interesting is its ability to store gases such as carbon dioxide.  Read More

Colorado Integrated Solar Project

The world's first hybrid solar/coal power plant has been built near Palisade in Colorado. Xcel Energy and Abengoa Solar are partnering on the demonstration project which uses solar parabolic trough technology to supplement the use of coal. Initially, it's expected to reduce the emissions generated by the Cameo Station's Unit 2 plant by three to five percent, but it's thought that this could increase to up to ten percent.  Read More

If our politicians continue contributing to global warming through spouting hot air, German industrial designer Mario Pitsch's concept for the Nomad - a sustainable "cross-country RV for the far future" - may need to become a reality sooner rather than later.  Read More

Chemist Robert Perry checks a flask containing an ingredient similar to those found in sha...

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.  Read More

Dr Philip Rasch is Pacific Northwest National Laboratory's first Chief Scientist for Clima...

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

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.  Read More

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.  Read More

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
