Been toying with the idea of using Augmented Reality in your classroom or library? Here's your chance to use the latest in AR to excite your students and get them looking at environmental issues through a new lens, then lens of their smart phone, iPad or tablet. If you are looking for a super #edtech way to engage your students, I have just the thing for you this World Environment Day - June 5. How about  a 700 x 1156 pixel poster which when scanned with the Augmented Reality (AR) app Layar will display rich  media elements.

Consumers could save up to 10 per cent on power bills thanks to a new energy saving solution designed by two PhD students at the University of Sydney. The MyPower Energy Platform allows users to monitor the power consumption of individual appliances and determines the best times to use them.

But how much can wind farms and solar panels contribute to a solution? Are they really the best option for Australia's energy future? And what part does the media play in the communication of all of this? The Science behind the headlines event (22 May 2012) held by RiAus attempted to answer these questions by combining a panel of scientists with experienced journalists - led by RiAus Programs Co-ordinator James Byrne. Each of the participants' knowledge of their specific field made for a varied and vibrant discussion that covered a wide range of topics. Is the public really aware of alternative energy options?

There are emerging radical technologies that have the potential to change the way we live. This video on Zero Emission Cities is third summary of a series of conversations had at the NETS Annual Foresighting Event on Three Technologies that Will Change the Way We Live. The video is made by RiAUS.

BONN, Germany, May 24 (Reuters) - Greenhouse gas emissions in 2020 could rise to nine billion tonnes above what is needed to limit global warming as some countries look set to miss their emissions cut targets, a report by three climate research groups said on Wednesday.

Coastal seagrass can store more heat-trapping carbon per square kilometre than forests can, which means these coastal plants could be part of the solution to climate change. Even though seagrasses occupy less than 0.2 per cent of the world's oceans, they can hold up to 83,000 tonne of carbon per square kilometre, a global team of researchers reported in the journal Nature Geoscience.

Investment in renewable energy infrastructure is outstripping that for fossil fuels. Investment was equal in 2008, but the balance has swung since. During 2011, globally, $40 billion was invested in fossil fuels. $260 billion was invested in renewables.  In the past year the price of photo voltaic cells has dropped by 50%. Peter Newman describes the growth of investment in renewable as exponential. He says we are living through one of the most dramatic periods in history as fossil fuels are being phased out.

One of the world's most complex experiments on the impact of rising levels of carbon dioxide is taking shape in eastern Australia, where giant steel frames nine stories high have been built on native woodland.  The project near Sydney will mimic future climatic conditions by simulating higher atmospheric concentrations of carbon dioxide. Carbon dioxide is pumped into an environmental "time machine" on the outskirts of Sydney, aiming to predict how vegetation will react to future climate change.

At the Mauna Loa Observatory in Hawaii, the latest on-site measurements of carbon dioxide in the atmosphere by the Scripps Institute of Oceanography reveal that global atmospheric carbon-dioxide (CO2) concentrations reached 391.3 parts per million (ppm) in 2011, up from 388.56 ppm in 2010 and from 280 ppm from pre-industrial times. According to the Intergovernmental Panel on Climate Change (IPCC), in order to have a 90-percent chance of avoiding dangerous changes in climate, greenhouse-gases (GHGs) concentrations need to be stabilized at 450 ppm, which would roughly translate into an average temperature increase of 2° Celsius. This means that to stabilize GHG concentrations at 450 ppm, global GHG emissions will need to peak before 2015 and be reduced to 50 percent of their 2000 level by 2050.

"A new report released by the United Nations calls on world governments to change the way they do business, end fossil fuel subsidies and factor in social and environmental costs into the measurement of economic activity. It notes that the standard method of calculating economic growth through measures such as GDP ignores the impacts on the planet and food and water resources."

Welcome to the Anthropocene is a website which is designed to improve our collective understanding of the Earth system. The site aims to inspire, educate and engage people about humanity's impact on Earth. Its unique combination of high-level scientific data and powerful imagery will help people visualize and better understand humanity's geographic imprint in recent time. Watch a 3-minute journey through the last 250 years of our history, from the start of the Industrial Revolution to the Rio+20 Summit. The film charts the growth of humanity into a global force on an equivalent scale to major geological processes.

Planet Under Pressure 2012 was the largest gathering of global change scientists leading up to the United Nations Conference on Sustainable Development (Rio+20) with a total of 3,018 delegates at the conference venue and over 3,500 that attended virtually via live webstreaming. The Plenary sessions and the Daily Planet news show continue to draw audiences world wide as they are available On Demand.

"By Giles Parkinson on 20 April 2012 California-based Sungevity is set to become the first solar company in Australia to offer zero-cost rooftop solar, teaming up with local company Nickel Energy to offer pay-as-you-go leasing deals that have proved enormously popular in the US."

A clear change in salinity has been detected in the world's oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle. In a paper published today in the journal Science, Australian scientists from the CSIRO and the Lawrence Livermore National Laboratory, California, reported changing patterns of salinity in the global ocean during the past 50 years, marking a clear fingerprint of climate change.

At MyGarbology, you'll find an interactive online game that teaches about Garbology and answers the question, "Where should my waste go?" You'll also find lessons and activities to extend your Garbology experience, from how to pack a waste-less lunch to getting the dirt on composting. Plus, read our Trash Talk blog for stories of Garbology in practice. In the classroom or at home, you can make Garbology a part of your everyday life.

Dr Tom Chalko has built an off-grid Eco-house at Mount Best in South Gippsland. This is the website associated with the house in which Chalko writes about the Eco-friendly aspects of the house including the use of a modified chest fridge

TWO brands of olive oil, one from Australia, the other shipped 16,000 kilometres from Italy, sit on a supermarket shelf. Most eco-friendly shoppers would reach for the Australian oil. But despite burning less fossil fuel to get here, it may not be better for the planet. Contrary to popular belief, ''food miles'', or the distance food has travelled before we buy it, is a poor indicator of our food's total greenhouse gas emissions, or ''carbon footprint''. Advertisement: Story continues below More important is the way our food is farmed and produced, and how far we drive to buy it. CSIRO studies are expected to show how emissions from farming and food production eclipse those from food freight.

"The official data comes from the Office of the Renewable Energy Regulator. It shows that while inner-city suburbs often have some of the lowest rates of solar installation, those in regional areas and lower-income suburbs, retirement belts and some coastal regions have embraced solar in the highest numbers.
