“We're running the planet like a subprime loan,” Dr. Johan Rockström of the Stockholm Resilience Centre said. A coordinated response would reduce the risks of both kinds of crises in the future.
Climate change, water and food scarcity, energy security and dangerous pollution are among urgent and accelerating problems across all aspects of the Earth system, the summit of high profile experts from 22 countries confirmed. Convened by the International Geosphere-Biosphere Programme (IGBP) and the Earth System Science Partnership (ESSP), summit participants noted the alarming fact that global carbon emissions have been increasing faster than any of the IPCC's scenarios from just 5 years ago, according to recent measurements.
“The consequences of the financial breakdown threaten the economic system. The consequences of the breakdown of the ecological system will be far worse in just a slightly longer time frame. Now as you're going to fix a short-term problem, take the opportunity to fix these long-term problems,” said Prof. Thomas B Johansson, a Lund University energy expert who is also Co-Chair of the Global Energy Assessment.
New economic agreements can and should heed natural limits and put the global recovery on a less carbon and resource intensive pathway. Recent economic trends were on course to raise global temperature by 4 to 6 degrees by the year 2100, levels considered catastrophic, according to IPCC projections.
Greener societies would lower risks while providing better quality of life, eliminating poverty and enhancing social coherence. In contrast, using the conventional measure of GDP growth as the lead indicator of national policies “has been badly misleading us,” Prof. Robert Costanza, an ecological economist at the University of Vermont, noted here.
New policies must tackle problems using an integrated Earth systems approach, including all human-environment interactions. Dr. Jill Jäger, senior researcher at the Sustainable Europe Research Institute, explained that what is missing are flexible processes that allow both multi-part dialogue and higher rates of learning to link expert knowledge to action effectively.
“The situation requires urgent action, the equivalent of war-time mobilisation. We need to drive solutions together, through best policies from governments, best practices from industry, and best behaviours from consumers,” commented Mr. Anthony Simon, a former senior Unilever executive now active in networks including the World Business Council for Sustainable Development.
The summit, an activity of IGBP’s “The Planet in 2050” research initiative, tasked 4 working groups on energy technology, land-use, culture-development-economy, and interchanges with the Earth system, to define desirable visions of the planet in 2050 and identify pathways, obstacles and opportunities. It will soon publish a public report. “A plan for a sustainable planet is doable,” Prof. Guy Brasseur of the US National Center for Atmospheric Research and one of the meeting's initiators, said. “It requires immediate measures. Long term, it will require different education systems that are conceived around the need to reconcile human beings with the rest of nature.”

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
