Geoengineering - the case is not made

Clive Hamilton

14th February 2015

The geoengineering genie should remain firmly stopped up in its bottle until a robust case is made for letting it out, writes Clive Hamilton - and that's something the NRC's new report signally fails to achieve, providing no rationale for deploying the technology, or even experimenting with it. more...

Satellites, mathematics and drones take down Africa's poachers

Thomas Snitch

3rd February 2015

Using new technologies to take on poaching in Africa is reaping big dividends, writes Thomas Snitch. Where drones are deployed as part of an integrated package of measures, poachers quickly give up. The trouble is, they move to other unprotected locations. So we must extend the program to all of Africa's most at-risk areas. more...

Beginning to see the light ... shining the sun's rays into Cairo's dark streets

Patrick Keddie

4th February 2015

Egyptian researchers have come up with a solution to the a lack of sunlight in Cairo's narrow and dingy streets, writes Patrick Keddie: a sine-wave panel that reflects light as soon as the sun rises. Initial tests indicate a potential five-fold increase in light levels. more...

Goodbye oil! Soon all cars will be electric - because they are better

Chris Goodall

10th February 2015

78 records didn't come to an end because the world ran out of shellac, writes Chris Goodall. And today's cars won't be made obsolete by a shortage of oil, or even climate change. The transition will be driven by falling prices, long range, clean air laws, and the superb style, performance and driving experience they offer. more...

Only a mug would bet on carbon storage over renewables

John Quiggin

16th January 2015

From Australia to the UK, governments are pinning their hopes on 'carbon capture' technology stuck onto coal power stations, writes John Quiggin. But their choice carries a high risk of failure - the smart money is on renewables, energy storage and responsive power grids. more...

Information to the people! The coming air quality revolution

Prashant Kumar

15th January 2015

Air quality across the UK is currently monitored by just a few hundred fixed stations, writes Prashant Kumar. That leaves most of us ignorant about the pollution we are breathing. But tiny air quality sensors in our mobile phones could soon create a network of millions of data points - and spur much needed official action to clean our air. more...

New technologies can help poor farmers - just not the ones you're thinking of

Tony Juniper

18th November 2014

Modern technology has a lot to offer small farmers in poor countries, writes Tony Juniper - just not the GMOs and pesticides that are widely touted. But how about film, digital communications and smart phones? These new media can empower farmers and allow them to share knowledge and experience of how to produce more, from less. more...

IPCC: rapid emissions cuts vital to stop worst impacts of climate change

Damian Carrington / The Guardian

3rd November 2014

The IPCC's most important ever assessment of global warming warns that the world must cut its carbon emissions must be cut sharply and soon, writes Damian Carrington - and the cost is affordable. But in fact, emissions are rising at record levels, and the IPCC's strong support for unproven-at-scale CCS technology will leave many mystified. more...

UK faces serious winter blackout risk - National Grid's rosy nuclear forecast fails reality test

Chris Goodall

31st October 2014

The National Grid's forecast for UK power supply this winter relies on overstating the availability of increasingly unreliable nuclear power stations, writes Chris Goodall. Realistic estimates of nuclear, gas and coal power station availability shrink the 'safety margin' to zero. more...

Seaweed problem could provide biofuel solution

Paul Brown

14th March 2015

Biofuels are controversial because they are often produced from food crops or grown on farmland, writes Paul Brown, creating extra pressure on land and forests. But a common algae found in abundance around coastlines and clogging up beaches may be the answer.
