Surprising insights into climate change

The tropopause, the shifting layer between the troposphere and stratosphere, has increased by about 200 meters over the past two decades, primarily due to greenhouse gases and ozone

Climate researchers from the USA, Germany and Great Britain present model calculations in Science that shed new light on the climatic changes caused by the earth’s inhabitants. Whereas previously the focus was on the temperature rise on Earth or in the stratosphere, scientists are now looking at the tropopause as a marker for unpredictable climatic changes. The calculation is based on satellite data for the period from 1979 to 1999. Using information on greenhouse gases, aerosols, ozone, solar energy and volcanic activity, scientists simulate the conditions for the 20th century. Century. According to their time series analyses, the temperature has been changing rapidly over the last 20 to 30 years: in the troposphere it is rising by about 0.07 degrees Celsius per decade, while in the stratosphere there is a cooling of the same order of magnitude.

Is solar power still worthwhile??

Yes, but with the solar tax plans of the German government it can become difficult

In 2014, the photovoltaic industry will continue to grow by 20% worldwide, as it did in 2013. The German Solar Industry Association (BSW Solar) is counting on this. The reasons are the growing interest in climate change, lower costs for PV modules and the increasing competitiveness of solar power.

Especially in China, Japan, South Korea, Taiwan and California, PV has taken off like it did in Germany a short time ago. But in this country, the grand coalition is in the process of destroying this successful industry of the future. Even in foggy Great Britain, far more was added in 2014 than here: 1100 megawatts of PV line have been installed on the island so far this year, compared with just 460 in Germany over the same period.


The “fight against the right” has failed

The fight against the right is the modern form of medieval exorcism and is also conducted with magical rituals

In Saxony, the NPD is about as strong as the SPD, and the brown comrades are the second strongest force among first-time voters. Time to draw a conclusion: The fight against the right has failed. The motto "Youth for Tolerance and Democracy" has not been successful. This is indisputable, or someone would cynically claim that without the demand programs like Civitas – initiativ gegen Rechtsextremismus in den neuen Bundesladern everything would be much worse and a quarter of all eligible voters would vote for neo-Nazis today.

It is also indisputable that no one will admit that it is the governmental "Antifa", initiated after the media hype against right-wing extremism five years ago, is all about hot air and worried attitudes in permanence. The "Fight against the right" was a moral-theological meta-discourse, flanked by the appropriate hysterical reports, which, like the "Fight against drugs", has nothing at all to do with reality and therefore had to fail already in the beginning.

"Best times were never in the cards" – Criticism grows louder

The World Athletics Championships have come to an end in Doha. Somehow the spectacle in Qatar, one of the richest countries in the world, didn’t create the right atmosphere. Collapsed athletes, empty ranges in the capital arena, lazily faded out conditions on the construction sites around, and everywhere traceable: The absolute disparity between a rich high snobiety and more than two million underprivileged people. Of the statistically recorded 2.7 million inhabitants of Qatar, about 2.3 million are migrant workers from Asia and Arab countries.


Corona: provision female, dying male

Corona: precaution female, dying male

Significantly more males die from covid-19 than females. This is partly due to genetics, but on the other hand to the "unmanly" image of health care and role stereotypes

The Corona pandemic is – also – a gender ie, because far more men than women die in connection with Covid-19, while more suspected cases of severe side effects of vaccines occur in women. Both of these reflect findings from gender-based health research. solutions were gender-sensitive health education for boys and men and greater consideration of female biology in the development of drugs and vaccines.

In principle, Covid-19 is and remains a viral disease, sometimes serious, and it is not the fault of anyone to suffer – or even to die – from it. In this respect, it is not about clarifying the question of guilt, but about a better understanding of the effects of the pandemic, including those on subjective health and infection prophylaxis. In this regard, the greater involvement of men among those officially registered as having died in connection with Covid-19 is striking. According to the RKI are considered "deceased in connection with Covid-19", who tested positive for Sars-Cov-2 by PCR test.

Debate about land consumption and new construction of single-family homes seems to come at an inopportune time, but shows that concepts for more quality of life in the city and the countryside are lacking

No, neither the head of the Grunen parliamentary group in the Bundestag, Anton Hofreiter, nor the outgoing head of the Left Party, Bernd Riexinger, have come out in favor of a ban on the construction of new single-family homes. But after just under a year of Corona decreases, it was clumsy of Hofreiter, at least from an election campaign point of view, to problematize this form of housing – not only because of the single-family home owners, but also because at the moment, according to surveys, a great many people are considering whether they can somehow afford it after all.


Artificial power plant in the micro-mab

Plants receive and store light energy very effectively – in a way that researchers from Switzerland and Germany have been able to imitate artificially for the first time

Man, as proud as he is of his constructions visible even from space (often they are walls), nevertheless uses again and again astonishingly ineffective basic principles. For example, the controversial Three Gorges Dam impounds over 1000 square kilometers of water to generate a full 18 gigawatts of power. Energy, that is the basic principle, is obtained from the fact that the water is so unevenly distributed between the reservoir and the outflow.

Biological systems work in a similar but much more effective way, for example during and after photosynthesis. There, too, it is a matter of first capturing energy and using these means to accumulate something – only on a much smaller scale. Nature uses a suitable process to concentrate ions or protons on one side of a biological membrane – and when the energy stored in this way needs to be called up, it opens the floodgates.


Technology as a continuation of the body

A conversation with the Australian media artist Stelarc

Australian media artist Stelarc has been exploring the relationship between man and machine for over 20 years. In sensational actions – such as a sculpture sunk in the stomach or a performance with an industrial robot – he has repeatedly stimulated reflection on this interface. In recent years, Stelarc has also experimented with the Internet. The first time, by the way, was in 1995, when the exhibition Telepolis took place in Luxembourg, from which this online magazine emerged.
