In 1975, Broecker published the article “Climate Change: Are We on the Brink of a Pronounced Global Warming?” in the journal Science, marking the first ever mention of the term “global warming” in a scientific publication.
In this article, he also predicted that the rise in anthropogenic CO2 emissions would weaken the ocean’s ability to withdraw carbon dioxide from the atmosphere, leading to pronounced warming at the start of the 21st century – a prediction that has proved all too true.
The BBVA Foundation Frontiers of Knowledge Awards seek to recognize and encourage world-class research and artistic creation and can be considered second only to the Nobel Prize in their monetary amount, an annual 3.2 million euros, and the breadth of the scientific and artistic areas covered. They are also the only international awards reserving a category for Climate Change.
The awards take in eight categories, carrying a cash prize of 400,000 euros each. The Climate Change award, the first to be decided, is to honor endeavors of a diverse nature – from research through to practical actions and initiatives - in the race against climate change, one of the crucial issues facing 21st century society.
The jury in this inaugural edition singled out the pioneering quality of Broecker’s work, which has opened up new avenues of research vital to our understanding of climate and its evolution. Special mention goes to the laureate’s knowledge contribution with regard to “abrupt changes”; processes which trigger extreme and sudden changes in the climate system. Today’s rapid thawing of the Arctic polar cap threatens to trigger one such abrupt event: the alteration of the main current distributing heat across ocean basins (the thermohaline circulation, also known as the oceanic heat conveyor belt).
In the words of the award certificate, Broecker’s “seminal” research into the oceans’ biological and chemical processes “pioneered the development of Earth System Science as the basis for understanding global climate change, both past and present”. It also highlights “his holistic approach”, which has led him to identify “the mechanisms of abrupt climate change”.
“Prof. Broecker has been an eloquent educator and a forceful champion of efforts to address the risks of greenhouse gas emissions from human activities”, concludes the jury in its resolution.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
