Astronomers fix the unprecedented decline of sun activity. Information of supervisions throw scientists into confusion. On the nearest to Earth star there are not spots and little flashes are satisfied, and on the whole sun activity is at such low level first
for 100 years. Usually activity of a sun changes during a 11-letnego cycle. On the nosedive of activity the magnetic field of a Sun causes different effects: from the surface of star the clubs of hot gas break forth measuring with a planet, constantly there are flashes. The quiet comes after it
period. It was expected last year, that a sun, passing a quiet period, would begin to be made burning hot. However much it happened: pressure of sun wind appeared minimum for 50 years, radioizluchenie - for 55 years, Vvs.Po passes to the words of professor Louisa Khara from London
University college, neyasno, why it takes place and when a Sun will begin to show large activity. «No signs of change while not evidently», — it declared.
state. Other group of astronomers supposes thus, that he is expected by another «period of calmness»to the .v middle XVII ages alike quiet period in the Sunshine — known as «Minimum Maundera» — lasted 70 years and became reason «small ice-age». It allowed
to assert some scientists, that a similar drop in temperature in our days will become the original answer of a Sun for the change of climate.A professor Mike Lokvud from the university of Sautgemptona considers this approach too simplified. «It would be desirable, certainly, that a Sun came
to us for help, but, unfortunately, information of researches does not allow so to consider», — he said.Professor Lokvud noticed one of the first, that activity of a Sun is unusually small gradually — from 1985 — goes down, while a global rise in temperature grows only
the rates.«If attentively to study information, becomes quite obvious, that krit
Lokvud supposes that except for a 11-godichnogo period a Sun has more protracted cycle of development, plugging in itself centuries. He suggests to consider 1985 year «by a maximal mark» in this long period of change to sun activity, and Minimum Maundera — him
by the lowest index. «We are included in a middle phase», — Lokvud adds. to his opinion, will pass yet no less than 100 years, before a Sun again will go down to the indexes of Minimum Mandera. added that the current small dimming of a Sun did not neutralize a consequence
global rise in temperature, reason of which is the use of nevozobnovlyaemykh types of fuel.From data of the Intergovernmental group on climatic changes, a middle temperature on Earth for the last 70 years grew from the beginning of XX age on 0,7 degrees celsius.
It is expected that the increase of temperature will proceed. Prognosis on an end XXI ages of neuteshitelen: a temperature on the average will grow from 1,8 to 4 degrees. However much nobody can while suppose, how increase and diminishing of activity of a Sun, indexes of which
change during ages, will influence on life of Earth.
