According to the data of different international organizations provided and analysed by professors Yolanda Castro Díez and María Jesús Esteban Parra, of the department of Applied Physics of the University of Granada, the average rise in global temperature in the 20th century was 0.6 ºC, a figure that amount to 0.65 ºC when we analyse the period between 1901 and 2005. Five hundredth in five years, which could seem insignificant but we can easily understand its value if we compare it to this other data: in the passing from a glacial to an interglacial period (which could amount to 10,000 years), the rise in temperature is in the region of 0.1 ºC per century.
According to the experts, in studies on climate variability of the UGR, the years which experienced a higher global warming were between 1910 y 1945 (in the ratio of 0.14 ºC per decade) and between 1979 and 2005 (0.17 ºC / decade). Besides, the warmer years were those between 2005 and 1998, and between 2001 and 2005 the planet experienced five of the six warmest years of the last century.
The data provided by the experts of the UGR reveal very interesting aspects, such as that from 1979 the global temperature has risen approximately twice as much than in oceans: 0.25 ºC per decade against 0.13. In addition, the average sea level rose almost 2 millimetres per year in the last 40 years, an amount that goes beyond the 3 millimetres per year if we analyse the last decade.
“Likewise, the data point out the appearance of a series of extremely heavy rain, which will probably be more noticeable in the next years due to global warming”, point out the researchers. Regarding the Arctic ice extension, the data obtained by the satellite since 1978 show this extension has decreased by 2.7 % each decade (annual average), a figure increasing up to 7.4 % each decade in summer months.
Professors Castro and Esteban have developed several research projects connected with the study of variability and climate change financed by the Spanish Ministry of Education and Science.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
