The sun may be cold, but wait the Little Ice Age is not worth According to Mike Lockwood, professor of the University of Reading (UK), solar activity decreases very rapidly - more rapidly than in the past 9300 years.

He and his colleagues are now engaged in trying to predict what will happen in the next decade if the first big solar minimum for the last four centuries. The concern is that a normal 11-year solar cycle will stop for a while and the sun is almost completely deprived of spots for several decades. Last summer, the number of sunspots was to achieve the maximum, but it never happened.
Mr. Lockwood believes that there is a 25 percent chance of repeating last big wage - the Maunder minimum that was observed at the end of the XVII century, when the sunspot was as much as 70 years. Two years ago, the same Lockwood estimated the chances of a recurrence of this phenomenon in the region of 10%.
Maunder Minimum coincided in Europe with the most savage winters for all the Little Ice Age - the era of unusually strong cooling for several centuries has engulfed several areas of the Earth. The study of tree rings showed that in the Northern Hemisphere, the average temperature dropped to 0,4 C.
Mr. Lockwood does not think the new high at least bring with it the Little Ice Age. Man-made global warming, he said - a more significant factor in global temperature than the solar cycle. Since 1880 the planet warmed by 0,85 C, and this is clearly not the limit, according to the latest data of the Intergovernmental Panel on Climate Change.
Nevertheless entirely without consequences, of course, will not do. For example, in the UK at the time of reduced solar activity usually stand extreme cold. In addition, it can slow down the jet stream in the atmosphere and thereby cause a series of inter-related extreme weather events like the Russian heat wave of 2010, which was followed by devastating floods in Pakistan.
Over the last 10 thousand years was 24 large solar minimum. The history of these periods can be restored by isotopes - such as carbon-14, which is created by cosmic rays in the atmosphere. Due to increased solar activity solar wind deflecting cosmic rays away from Earth, so the lower solar activity, more powerful cosmic radiation and generates more specific isotopes.
Changing the number of isotopes measured in tree rings, which absorb carbon-14, and ice cores, preferring beryllium-10.
The current decline in solar activity began after the last great moment for the solar maximum in 1956, stressed Mr. Lockwood. The recent decline has accelerated, and the lack of sunspots this summer was the first alarm bell.
How strong solar cycles affect global temperature, remains in question. Perhaps that was the reduction of solar activity to some extent the reason that global warming has slowed.
Mike probably right about the fact that the Sun may return to the level of activity of the Maunder minimum, - says an expert on the physics of the atmosphere Joanna Haigh of Imperial College (UK). - But even under the most optimistic scenario (assuming the minimum global warming and strong solar minimum) cold, which will bring with it a decrease in solar activity, just neutralize the greenhouse effect. So no ice age.
Most likely, the solar minimum is only slightly rein warming, which will return in full force as soon as the active light will begin to increase again to its normal state.
Solar activity continues to free-fall. But wait for the Little Ice Age is still not worth it.
ICE AGE NOW: Monumental Snowfall In Europe - More Flight Disruptions Causes Widespread Chaos!

January 21, 2013 - EUROPE - Hundreds of flights were cancelled and hazardous roads and railways disrupted traffic and caused countless accidents across Europe on Monday as heavy snow and freezing weather gripped the continent. Frankfurt airport, Germany's main air hub, cancelled around 500 departing and arriving flights, representing 40 percent of its daily schedule.
The busiest airport in Europe, London Heathrow, scrapped more than 200 flights. Heathrow said a decision was taken 24 hours in advance to cancel 130 flights due to predicted poor visibility, but problems elsewhere in Europe were having an impact too. "The additional cancellations are because a number of airports elsewhere in Europe are experiencing problems so that has a knock-on effect for us," an airport spokesman said. Heathrow has spent 36 million pounds ($57 million) on upgrading its snow-clearing equipment since 2010, when freezing temperatures and snow almost brought the airport to a halt in the approach to Christmas. Freezing rain and snow also led to treacherous conditions on railways and roads, triggering numerous accidents. In southwestern Germany, police recorded more than 1,000 weather-related accidents and in the northeast, near Berlin, an entire section of motorway was shut to traffic.
In Belgium, three people died and two others were seriously injured when a minibus they were travelling in skidded off the road, overturned and caught fire at a motorway exit near Bruges, local authorities said. One woman died in the southern English coastal town of Deal after collapsing in the snow. Further snowfall was forecast for Frankfurt late Monday, with a spokesman for the city's airport telling AFP that it expected further disruption to flights on Tuesday. When asked how many flights would be affected, the spokesman added: "we can only wait and see what happens tonight." Europe's number three airport, Paris's Charles de Gaulle, was also hit. France's civil aviation authority DGAC said it expected to scrap 40 percent of flights to and from Charles de Gaulle and Paris's other main airport, Orly, as a precautionary measure following heavy snowfall on Sunday. Even Munich, a city usually accustomed to taking snow in its stride, cancelled 161 flights at its airport as it grappled with the exceptional conditions.
