Upward trend of temperatures in the Iberian Peninsula

26.02.2007
Matthias Staudt has carried out an exhaustive work to homogenize temperature records of the Iberian Peninsula in the last hundred and thirty years.

The curious thing is the rise in minimum temperatures. Tablelands are the most representative area from a climatic point of view; if we take them as a reference, according to Staudt´s systematized data, Spanish minimum temperatures have risen about a degree from the first thirty years of the XX century to the last three decades.

The rise in maximum temperatures is lower and more irregular than that of the minimums, which have risen in all the regions of the national climate map, especially in the Valleys of the River Ebro and Guadalquivir, a degree and a half. Minimums of cities like Sevilla have risen 2 centigrade degrees in the last years. If we correct the so-called urban effect, typical of big and medium cities, the rise is of 1.6 degrees. In the Mediterranean and Cantabrian coast, warming is lower.

According to experts´ data, the average temperature of the planet raised considerably in the last century. Specifically, from 1880 to 2000, an average of 0.7 centigrade degrees. “The trend found in the Iberian Peninsula agrees with the global one (at a planetary level) and can be observed above all in the last thirty years”, points out María Jesús Esteban Parra, director of the thesis together with Yolanda Castro Díez. To come to this conclusion, the scientists of the research group Atmosphere Physics of the UGR (Universidad de Granada [http://www.ugr.es]) have systematized the quality of the data of the Natioanl Institute of Meteorology, since the 1970s.

After an introduction to the climatic variability of the Peninsula, forty-five Spanish original time series have been catalogued monthly averaged. It is not an easy job. “Sometimes, weather stations which take temperatures move or measures get affected by different non-meteorological factors, like urbanization. If these changes are not taken into account and corrected, data can not be compared to the previous ones”, explains doctor Staudt.

Therefore, “this work is essential because if we do not homogenize the data, we can not come to any conclusion about climate change”, concludes Professor Castro. To go deeply into climatology, they do research into variables like sunny hours, cloudiness and their connection with temperatures. The typical global difference in the behaviour of maximum and minimum temperatures has disappeared since 1970. Thus, in the last thirty years, both groups clearly rise whereas cloudiness decreases, which may mean an increase of the subtropical nature of the peninsular climate.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

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...
