Owl wings may inspire new design for quieting aircrafts
November 19, 2012 01:12 PM - ClickGreen Staff, ClickGreen
Airlines and airports could soon be relying on nature for a unique way to reduce noise pollution after researchers found owl feathers are designed to minimize sound while in flight. Owls have long been known to have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth. Now researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft.
Male motorists are more likely to drive in a more environmentally friendly manner than females, according to the surprising results of a new survey. And more men than women say they will only use a car when cycling, public transport or walking are not an option. The new research, published today, also reveals that the rising cost of car ownership is forcing a new approach to mobility, with almost two-thirds (65 per cent) of UK drivers admitting that they have changed their motoring habits in light of the recession and rising fuel costs, and 30 per cent of motorists now only use their car for essential trips.
New research finds mine waste could provide an effective CO2 trap
November 15, 2012 08:30 AM - ClickGreen staff, ClickGreen
It's time to economically value the greenhouse gas-trapping potential of mine waste and start making money from it, says mining engineer and geologist Michael Hitch of the University of British Columbia (UBC). Hitch studies the value of mine waste rock for its CO2-sequestration potential, or "SP." He says mining companies across Canada will, in future, be able to offset CO2 emissions with so-named "SP rock," and within 25 years could even be selling emissions credits.
Are Greenhouse Gas Emissions Delaying the Start of an Ice Age?
November 13, 2012 07:38 AM - ClickGreen Staff, ClickGreen
Mankind's emissions of fossil carbon and the resulting increase in temperature could prove to be our salvation from the next ice age. According to new research from the University of Gothenburg, Sweden, the current increase in the extent of peatland is having the opposite effect. "We are probably entering a new ice age right now. However, we're not noticing it due to the effects of carbon dioxide", says researcher Professor Lars Franzén. Looking back over the past three million years, the earth has experienced at least 30 periods of ice age, known as ice age pulses. The periods in between are called interglacials.
Growth of Renewables will continue with continued subsidies
November 12, 2012 03:10 PM - ClickGreen Staff, ClickGreen
The International Energy Agency predicts renewables will become the world's second-largest source of power generation by 2015 and close in on coal as the primary source by 2035. But according to the 2012 edition of its flagship publication, the World Energy Outlook, the agency warns this rapid increase is critically dependent on continued subsidies. It says in 2011, these subsidies (including for biofuels) amounted to $88 billion, but over the period to 2035 need to amount to $4.8 trillion; over half of this has already been committed to existing projects or is needed to meet 2020 targets.
Europe is exporting more waste than ever as illegal trade grows
November 8, 2012 08:47 AM - ClickGreen Staff, ClickGreen
As waste is increasingly moving across EU borders for recovery or disposal, the European Environment Agency (EEA) is warning of a big rise in the export of hazardous waste to countries outside of Europe. Increasingly stringent and harmonised waste policies in the EU have led countries to transport more waste material elsewhere, for example if they do not have the facilities to recycle or dispose of particular types of waste.
The risk of flooding and water shortage in 2013 has increased because the Government is too slow in changing the way we manage our water, environmental leaders warn. The authors of the Blueprint for Water report say that after two dry winters, it took Britain’s wettest ever summer to narrowly avert a serious drought. They warn that despite this summer’s flooding, another series of dry winters would put Britain right back under serious risk of drought.
Research reveals why sea levels are rising faster than previously feared
November 5, 2012 08:18 AM - ClickGreen Staff, ClickGreen
Sea levels are rising faster than expected from global warming and new research is said to reveal the reasons why. The last official IPCC report in 2007 projected a global sea level rise between 0.2 and 0.5 meters by the year 2100. But current sea-level rise measurements meet or exceed the high end of that range and suggest a rise of one meter or more by the end of the century.
Have Carbon Emissions Passed an Important Threshold?
November 5, 2012 06:33 AM - ClickGreen Staff, ClickGreen
The annual rate of reduction of carbon emissions per unit of GDP needed to limit global warming to 2ºC, has passed a critical threshold according to new analysis from PwC. And the report's author warn the rate of reduction now required has never been achieved before and add: "This isn't about shock tactics, it's simple maths." The analysis in the PwC Low Carbon Economy Index, measuring developed and emerging economies progress towards reducing emissions linked to economic output. It demonstrates that at current rates of emissions growth at least 6C degrees of warming could be possible by the end of the century.
Iskander Malaysia: World's First "Smart Metropolis"
November 2, 2012 09:40 AM - Editor, ClickGreen
Malaysia is currently building the world's most advanced low-carbon mega-city comparable in size to the area of Luxembourg, with an expected population of 3 million by 2025. Iskandar Malaysia, the first "smart metropolis" of Southeast Asia founded on principles of social integration as well as low carbon emissions thanks to a green economy and green technologies, is a potential template for urban development in emerging countries with burgeoning populations, international experts say.
