Little Ice Age climatic consequences
Some people believe that the current solar inactivity could bitinajava small ice age that could undo posljediceglobalnog climate warming
The sun has lately fallen nanajniže activity levels that are not recorded in the last 100 years, researchers said.
There are no spots, registered and very few solar bursts, and the results promatranjazbunjuju astronomers have recently gathered at the conference Britanskojastronomskoj.
sun normally goes krozciklus activity that lasts 11 years. When the peak, and it boils njegovaatmosfera ejects bursts super-hot gas that creates naZemlji polar light and possibly problems with električnimsustavima. After that, often spectacular action follows mirnijerazdoblje. | experts last year after a lull očekivalipočetak warming, because the next solar maksimumočekuje already in 2012. year. But instead, the star of our fallen na50-year minimum the effect of solar winds, the 55-year minimum uzračenju and 100-year minimum in sunspot activity.
Professor Louise Hara of the University College London says nijejasno what is happening with the sun or when it will again become active.
There is no indication that this might happen soon. Currently postojeznanstveni works by which we will soon return to normalu.Međutim, other experts argue that we enter into another razdobljedubljeg minimum. This is a great leading scientific debate, objasnilaje prof. Hara.
Scientists particularly concerned about this situation because jepoznato the mid-17th century on Earth occurred slightly ledenodoba a period of 70 years - from the 1645th to 1715th with a series neuobičajenohladnih winters in northern Earths hemisphere, and believes Seda was caused by the so-called. Maunderovim minimum. solar pjegepojavljivale were sporadic during this period and it looked as if sesolarni cycle completely disintegrated.
Some people therefore believe that bisadašnja inactivity of the Sun could be an announcement like ice dobakoje could undo the consequences of climate warming.
However, Professor. Mike Lockwood believes that something will happen. Careful observations show very clearly that the Sun has reached svojmaksimum 1985th and this is continuing today solarnihaktivnosti downward trend that has continued for several decades. Lockwoodobjašnjava to the Sun than the 11-year cycle is probably going ikroz other, more oscillations in which Maunderov predstavljajednu minimum of the lowest points. It is expected that the re-entry uMaunderov minimum needed more than 100 years, he said.
connection with the solar minimum periods of cold and possible fizikalnimehanizmi this phenomenon is still not fully understood. Astronomii meteorologists therefore closely monitor any changes in the Sun and its influence our planet. But now astronomers have snažneteleskope available and which satellites can closely monitor events on the Sun, TESE hope that this enigmatic team could soon be resolved, aeventualna predicted future ice ages on time.
