Fukushima: More radioactive xenon than Chernobyl

Biggest burden immediately after the earthquake - before the tsunami Read out An international team of researchers from Norway, Austria, Spain and the USA came to the conclusion that the super-GAU in Fukushima released 2.5 times as much radioactive noble gas xenon-133 as Chernobyl. According to the study, there are also "strong indications" that the release started on 11 March 2011 as a result of the earthquake already around 15 o'clock in Japan and thus before the arrival of the tsunami

China: Construction boom increases CO2 emissions

Researchers register reversal of a long-term trend Read out The construction of buildings, power plants and roads is the reason for the significant increase in Chinese CO2 emissions, according to a new study in the journal Environmental Science and Technology . The fast-growing investment in the infrastructure sector has led to an expansion of the construction sector and its energy- and CO2-intensive supply chain, such as the steel and cement industries, say researchers

Future greenhouse gas scenarios extended to 2300

Forecasts should also serve as the basis for the next IPCC report Read out Researchers have developed four new scenarios for future climate change that are intended to provide key common points of reference for researchers worldwide. For the first time, these scenarios include one that calculates the effects of ambitious emissions reductions, the researchers report in a special issue of the journal "Climatic Change"

Promoting technology can make climate protection cheaper

Computer simulation confirms the importance of targeted support measures Read out In order to achieve cost-effective climate protection, in addition to emissions trading, the promotion of new technologies is needed. This is what scientists from the Potsdam Institute for Climate Impact Research (PIK) have found in a new study

CCS carbon dioxide storage: less risk than expected?

Researchers use deaths from volcanic CO2 sources as a benchmark Vattenfall CCS pilot plant Schwarze Pumpe in Brandenburg © CC-by-sa 3.0 Read out The health hazards caused by the technical storage of carbon dioxide in the ground may be lower than many feared. This is now suggested by a study by British researchers in the journal Proceedings of the National Academy of Sciences.

Renewable energies: investments at record high

Leading developing countries in 2010 Read out Investments in clean energy are in the trend worldwide: In 2010, a total of 211 billion US dollars were spent on new renewable power generation plants - almost a third more than the year before. This is shown by the latest report of the United Nations Environment Program (UNEP)

China's sulfur emissions slowed climate change

Researchers find explanation for puzzling "break" in global warming Read out China, the emerging nation, has temporarily not fueled the global climate, despite its high greenhouse gas emissions, but even cooled it. Climatologists have found that the country's sulfur emissions from burning coal are responsible for a hitherto perturbed 'break' in climate change: between 1998 and 2008, global average temperatures remained nearly the same, although human Greenhouse gas emissions continued to rise during this period

Atomic exit is affordable

Study: Energiewende needs a show of strength Read out The sometimes highly controversial timing of nuclear phase-out has only a small impact on electricity prices for consumers. However, an exit well before 2020 could push up the emission of the greenhouse gas CO2 in Germany in the short term. The sticking point, however, is security of supply

Energy from wind and waves is not infinite

Natural limit of renewable energies at 1, 000 terawatts? Solar energy plant in the desert © Geri Kodey / DOE / NREL Read out For the first time, physicists have used thermodynamics to investigate the natural limits of renewable energies and the possible effects of climate change on their use. The analyzes suggest that the energy from wind and waves could be limited.
