Global Warming

Australian climate and ocean scientists are studying some of the planet's most remote areas using a multi-million dollar array of high-tech underwater equipment that provides data vital for the monitoring of almost one-third of the world's oceans. The kit of technology includes sensor floats and autonomous underwater vehicles, which combine with sensor tagged animals, moored scientific stations and satellite remote sensing to form the Integrated Marine Observing System (IMOS). All data collected is made available online, which represents a big step forward in climate science. Gizmag's Grant Banks takes a closer look at what makes IMOS tick.  Read More

Scientists are using a Scan Eagle UAV and image recognition software to track seals on the...

The Arctic region is currently experiencing a warming trend which is seeing the ice cap break apart, and may even ultimately result in the total absence of ice in the summer months. Many scientists attribute this trend to man made global warming, but whatever the cause, it’s not good news for the seals that breed, rest, and escape marine predators on the ice. In an effort to understand the full scope of the situation, scientists have turned to the Boeing-designed Scan Eagle – an unmanned aerial vehicle more often used for military reconnaissance.  Read More

Indian researchers have found that eggshells could be used for carbon capture and sequestr...

Carbon capture and sequestration (CCS) is a hot area of research in the effort to fight global warming through the process of removing carbon from the atmosphere and ferreting it away within carbon soaking materials, a team from the University of Calcutta has found an unexpected (or should that be uneggspected) material that could trap carbon from the atmosphere in the form of eggshells. The team has demonstrated that the membrane that lines an eggshell can absorb almost seven times its own weight of carbon dioxide from the atmosphere, allowing the gas to be stored until environmentally friendly methods of disposing, or even using it, can be found.  Read More

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

The Nomad is a concept for a futuristic cross-country RV and biosphere designed to cope wi...

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
