The current Solar Minimum, the same as the previous one (2008/2009), is very deep -- referred to as 'century-class' minimum. The only year with more spotless days was 1913 with 311. The previous Space Age record for the year with most spotless days was set in 2008 with 168. "Neutron monitors in Oulu are getting results similar to ours," Phillips said, referring to Earth to Sky Calculus cosmic ray measurements. "Oulu data show that cosmic rays have been increasing for the past 5 years and, moreover, are within percentage points of the Space Age record." "This type of radiation, which you can also find in medical X-ray machines and airport security scanners, has increased more than 20% in the stratosphere." Cosmic radiation affects our planet, all life on or near it and electronics, among other things. For the start, people in airplanes at 12 km (39 000 feet) can receive 10 times the cosmic ray dose than people on the sea level. Cosmic rays ionize the nitrogen and oxygen molecules in the atmosphere, which leads to a number of chemical reactions. They are also responsible for the continuous production of a number of unstable isotopes in the Earth's atmosphere, such as carbon-14. It has been postulated that cosmic radiation may have been responsible for major climatic change and mass-extinction in the past. According to Adrian Mellott and Mikhail Medvedev, 62-million-year cycles in biological marine populations correlate with the motion of the Earth relative to the galactic plane and increases in exposure to cosmic rays. The researchers suggest that this and gamma-ray bombardments deriving from local supernovae could have affected cancer and mutation rates, and might be linked to decisive alterations in the Earth's climate, and to the mass-extinctions of the Ordovician. Due to its effect on all biological life, cosmic radiation is one of the most important barriers standing in the way of plans for interplanetary travel by crewed spacecraft. In addition, cosmic rays have sufficient energy to alter the states of circuit components in electronic integrated circuits, causing transient errors to occur (such as corrupt data in memory devices or incorrect performance of CPUs). ... As the current solar cycle ends and the next one begins, cosmic radiation levels around us will stop rising and start falling. Poster Comment: We are entering a period of Global Cooling. During the Maunder Minimum the sun radiated less heat. Wheat prices rose as much as 400% in the UK. In 1709 the price of food in Europe rose 600%. The ground was frozen solid for a depth of one meter (40 inches.) But Dr Valentina Zarkhova has noticed that more significant than the slight global cooling is the reduction of the sun's magnetosphere. This allows more cosmic rays (nuclear particles from distant decaying stars) to strike the earth. The New Madrid fault had a major quake on 12-25-1699 during the Maunder Minimum. During the Dalton Minimum, the New Madrid fault had 4 quakes on 3 days in 1811-1812. Japanese scientists also noted an increase in the number of volcanoes during a Grand Solar Minimum. The likely cause of the increase in both quakes and volcanoes is the increased number of cosmic rays energizing the earth. Post Comment Private Reply Ignore Thread
