Lauded and criticised for offering a possible way out of the dangers of man made climate change, UK TV Channel 4's programme "The Great Global Warming Swindle", broadcast in 2007, suggested that global warming is due to a decrease in cosmic rays over the last hundred years.
This would cause a decrease in the production of low clouds allowing more heat from the sun to warm the Earth and cause global warming.
Research published today, Thursday 3 April, in the Institute of Physics' Environmental Research Letters shows how a team from Lancaster and Durham Universities sought a means to prove the correlation between the ionizing cosmic rays and the production of low cloud cover.
Previous research had shown a possible hint of such a correlation, using the results of the International Satellite Cloud Climatology Project, and this had been used to propose that global warming was all down to cosmic rays.
The new research shows that change in cloud cover over the Earth does not correlate to changes in cosmic ray intensity. Neither does it show increases and decreases during the sporadic bursts and decreases in the cosmic ray intensity which occur regularly.
One such very large burst caused the magnetic storm which blacked out the power in Quebec in 1989.
Professors Sloan from Lancaster University and Wolfendale from Durham University write, "No evidence could be found of changes in the low cloud cover from known changes in the cosmic ray ionization rate."

Space observation with radar to secure Germany's space infrastructure

Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
