Published today by the prestigious international journal Proceedings of the National Academy of Science (PNAS), the researchers have coined a new term, ‘tipping elements’, to describe those components of the climate system that are at risk of passing a tipping point.
The term ‘tipping point’ is used to describe a critical threshold at which a small change in human activity can have large, long-term consequences for the Earth’s climate system.
In this new research, lead author Prof Tim Lenton of the University of East Anglia (UEA) and colleagues at the Postdam Institute of Climate Impact Research (PIK), Carnegie Mellon University, Newcastle University and Oxford University have drawn up a shortlist of nine tipping elements relevant to current policy-making and calculated where their tipping points could lie. All of them could be tipped within the next 100 years.
The nine tipping elements and the time it will take them to undergo a major transition are:•Melting of Arctic sea-ice (approx 10 years)
“Society must not be lulled into a false sense of security by smooth projections of global change,” said Prof Lenton.
“Our findings suggest that a variety of tipping elements could reach their critical point within this century under human-induced climate change. The greatest threats are tipping of the Arctic sea-ice and the Greenland ice sheet, and at least five other elements could surprise us by exhibiting a nearby tipping point.”
‘Tipping elements in the Earth’s climate system’ by Tim Lenton (UEA and Tyndall Centre), Hermann Held (PIK), Elmar Kriegler (Carnegie Mellon University and PIK), Jim Hall (Newcastle University and Tyndall Centre), Wolfgang Lucht (PIK), Stefan Rahmstorf (PIK) and Hans Joachim Schellnhuber (PIK, Oxford University and Tyndall Centre) is published by PNAS in the week beginning Monday February 4.
The findings are based on a critical review of the literature, the results of a recent workshop held at the British Embassy in Berlin which brought together 36 international experts in the field, and an elicitation exercise involving a further 52 international experts.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
