3 April. Scientists using data from the expedition of the nineteenth century, determined that the temperature in the surface layer waters of the oceans over the last 135 years has increased by 0.6 degrees, according to the Internet portal LiveScience citing a study published in the journal Nature Climate Change.
A study conducted by researchers from the University of California San Diego with the support of the American administration, oceanic and atmospheric research (NOAA) showed that the global «warming» the ocean was already more than 100 years ago. Comparing the data of the Read more [...]
Scientists have calculated that the damage to the ecology of the planet can be 65% less if you manage to keep greenhouse gas emissions and the resulting global warming within stipulated by the UN Climate Conference, according to a study published in the journal Nature Climate Change. UN conference on climate change held in December 2012 in Doha (Qatar). It was decided that the human race needs to take urgent measures to keep average temperatures on the planet within two degrees Celsius over the period to 2100. Thus one of the main mechanisms must be tightly controlled, reducing greenhouse gas Read more [...]
5 June, the world watched astronomical event - the transit of Venus across the solar disk. Perhaps someone from the readers lucky enough to watch. I, alas, no. And everything seems to be fine, but ... there are some issues.First, let's look at the charts astronomically calculated trajectory passage of Venus.Now compare that calculated the experts and, in reality, was Venus.
Simple overlay photos and diagrams immediately reveals a strong deviation. Also, if you draw a line through the center points of Venus in the picture, then the trajectory will curve.We also offer a witness Read more [...]
Effective period - The period of time during which the activity of the body, caused by being hit by radioactive substances is reduced by half. The decrease is due to the radioactivity of the physical decay of a radioactive substance (see radioactivity) and biological excretion from the body. Radioactive substances are not fixed in any organs selectively, for example radioactive sodium, are rapidly eliminated from the body, causing a short effective period, calculated days. For deposition in the body of long-lived radioactive substances effective duration period is calculated in years. For Read more [...]
The most popular definition of risk is the probability that something undesirable happens due to accidental or intentional exposure to high-risk factors [58, 59]. When a scientific definition of risk  implementation risk is a random phenomenon, having probabilistic in nature, there is a risk - frequency implementation risks specific class or another - the probability of the event B when the event A (dimensionless quantity between 0 and 1).
Despite the fact that the concept of risk includes not only objective, but also subjective component, it operates with numbers, not emotions, and so it is Read more [...]
