http://www.endseurope.com/12955), McKinsey calculates the potential emission reductions and costs of more than two hundred mitigation actions across ten sectors and 21 regions from now to 2030.
The authors conclude it is technically and economically feasible to cut carbon emissions by 35 per cent by 2030 versus 1990 levels, amounting to a 38-gigatonnes (Gt) reduction. Achieving this would cost E200-300bn annually, below McKinsey's previous predictions and around half of UK economist Nicholas Stern's estimate (EE 30/03/07 http://www.endseurope.com/13290 and EE 30/10/06 http://www.endseurope.com/12571).
McKinsey identifies three priority abatement categories where the cost of action is under E60 per tonne of carbon. First, 14 Gt of carbon could be saved through energy efficiency improvements in vehicles, buildings and industrial equipment, largely at a net profit (EE 14/02/08 http://www.endseurope.com/14701).
Another 12Gt could be saved through the application of low-carbon energy technologies such as wind, nuclear, and hydropower, carbon capture and storage (CCS), and biofuels, the consultants say. These technologies could provide 70 per cent of global electricity in 2030 versus 30 per cent in 2005, they estimate.
Changes in forestry and land-use could save another 12Gt, according to the report. On top of these three main avenues for emission reductions, the authors suggest another 9Gt could be won through behavioural change, albeit at higher cost than E60 per tonne.
But capturing the full potential for emission reductions will be a "major challenge" say the authors (EE 12/11/08 http://www.endseurope.com/17112). It will require global cross-sectoral action and commitment, a strong policy framework, and a start on all this in 2010, they say.Follow-up: McKinsey report http://globalghgcostcurve.bymckinsey.com/ plus reactions from WWF

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
