A worst-case scenario of climate change from the possible future release of submerged methane hydrates predicts catastrophic warming in the atmosphere and rising sea level similar to conditions that preceded the last ice age. Renssen et al. simulated the climate response from a massive release of methane from gas hydrates in the oceans, using a three-dimensional model to estimate the changes to the atmosphere-sea ice-ocean system over 2,500 years.
Although the researchers do not speculate on what could initiate the temperature increase, their results indicate that an incremental oceanic warming above a few degrees Celsius [Fahrenheit] could initiate a chain reaction that would raise the water temperatures in the intermediate depths and disturb even more frozen hydrates.
The current study provides the most detailed examination of the potential warming caused by a methane hydrate-fueled enhancement of the greenhouse effect. Title: Modeling the climate response to a massive methane release from gas hydrates

Using ultrashort laser pulses, scientists in Max Planck Institute of Quantum Optics have demonstrated the emission of extreme ultraviolet radiation from thin dielectric films and have investigated the underlying mechanisms.
In 1961, only shortly after the invention of the first laser, scientists exposed silicon dioxide crystals (also known as quartz) to an intense ruby laser to...
The only professorship in Germany to date, one master's programme, one laboratory with worldwide unique equipment and the corresponding research results: The University of Würzburg is leading in the field of biofabrication.
Paul Dalton is presently the only professor of biofabrication in Germany. About a year ago, the Australian researcher relocated to the Würzburg department for...
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
