This work represents a significant advance for climatology. It is the first summary of what scientists have been able to reconstruct about climate sensitivity based on data from the past 65 million years and the assumptions that were behind the data. It also demonstrates that the climate forecasts in the IPCC reports agreed with the estimates of how nature has reacted to changes in the climate through the course of the earth’s history.
The research team has not, however, achieved one of its goals. “We had hoped to limit the range of current assumptions about climate sensitivity. In its last report, the IPCC summarised that the global temperature would rise 2.1 to 4.4 degrees C if the atmospheric carbon dioxide level rises to double the pre-industrial values. As it turns out, our climate sensitivity values are currently within this same range” says Dr Köhler.

KAIST researchers published an article on the development of a novel technique to precisely track the 3-D positions of optically-trapped particles having complicated geometry in high speed in the April 2015 issue of Optica.
Daejeon, Republic of Korea, April 23, 2015--Optical tweezers have been used as an invaluable tool for exerting micro-scale force on microscopic particles and...

Ever since computers have been small enough to be fixtures on desks and laps, their central processing has functioned something like an atomic Etch A Sketch, with electromagnetic fields pushing data bits into place to encode data.
Unfortunately, the same drawbacks and perils of the mechanical sketch board have been just as pervasive in computing: making a change often requires starting...
How is lightning initiated in thunderclouds? This is difficult to answer - how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. This surprising finding is published in Physical Review Letters on April 24th. The measurements were performed with the LOFAR radio telescope located in the Netherlands.

Max Planck researcher Buhalqem Mamtimin determines how much nitrogen oxide is released into the atmosphere from agriculturally used oases.
In order to make statements about current and future air pollution, scientists use models which simulate the Earth’s atmosphere. A lot of information such as...
