Is our Sun falling silent? Prepare for an impending Ice Age

GlobalIntelHub Planet Prepping

GIH: Climate change is now apparent for every person living on planet earth - it's no longer just anomalous events, but a complete different climate.  But we have only been keeping records for a short period, historically speaking.  It's possible that what we are experiencing now is a common cycle, but because of the short record span, there is not enough data to make a valid assessment  of a pattern.  Or, we could be living in an age of abrupt change that is unique to the history of our planet.  Regardless of the cause, we must be aware about it, and adapt accordingly.  Climate change will impact our lives in many ways, the economy, our health, and most importantly, our infrastructure.  If we did live in a period of a moderate climate, we have poorly designed and planned our infrastructure, that may not survive severe change.  Ice storms knock out power grids, solar events can cause a natural EMP that can knock out electronic infrastructure, and a rising sea can cause a problem for 90% of the world population that lives close to the sea (cities such as New York, London, Miami, Tokyo, Los Angeles, and many others, are all in low lying areas on the coast).  Checkout the following data from what gives us life and seasons, the Sun:

"I've been a solar physicist for 30 years, and I've never seen anything quite like this," says Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.

He shows me recent footage captured by spacecraft that have their sights trained on our star. The Sun is revealed in exquisite detail, but its face is strangely featureless.

"If you want to go back to see when the Sun was this inactive... you've got to go back about 100 years," he says.

This solar lull is baffling scientists, because right now the Sun should be awash with activity.

It has reached its solar maximum, the point in its 11-year cycle where activity is at a peak.

This giant ball of plasma should be peppered with sunspots, exploding with flares and spewing out huge clouds of charged particles into space in the form of coronal mass ejections.

But apart from the odd event, like some recent solar flares, it has been very quiet. And this damp squib of a maximum follows a solar minimum - the period when the Sun's activity troughs - that was longer and lower than scientists expected.

"It's completely taken me and many other solar scientists by surprise," says Dr Lucie Green, from University College London's Mullard Space Science Laboratory.

The drop off in activity is happening surprisingly quickly, and scientists are now watching closely to see if it will continue to plummet.

"It could mean a very, very inactive star, it would feel like the Sun is asleep... a very dormant ball of gas at the centre of our Solar System," explains Dr Green.

This, though, would certainly not be the first time this has happened.

During the latter half of the 17th Century, the Sun went through an extremely quiet phase - a period called the Maunder Minimum.

Historical records reveal that sunspots virtually disappeared during this time.

Dr Green says: "There is a very strong hint that the Sun is acting in the same way now as it did in the run-up to the Maunder Minimum."

Mike Lockwood, professor of space environment physics, from the University of Reading, thinks there is a significant chance that the Sun could become increasingly quiet.

An analysis of ice-cores, which hold a long-term record of solar activity, suggests the decline in activity is the fastest that has been seen in 10,000 years.

"It's an unusually rapid decline," explains Prof Lockwood.

"We estimate that within about 40 years or so there is a 10% to 20% - nearer 20% - probability that we'll be back in Maunder Minimum conditions."

The era of solar inactivity in the 17th Century coincided with a period of bitterly cold winters in Europe.

Cold, snowy winters could become the norm for Europe

And Prof Lockwood believes that this regional effect could have been in part driven by the dearth of activity on the Sun, and may happen again if our star continues to wane.

"It's a very active research topic at the present time, but we do think there is a mechanism in Europe where we should expect more cold winters when solar activity is low," he says.

He believes this local effect happens because the amount of ultraviolet light radiating from the Sun dips when solar activity is low.

This means that less UV radiation hits the stratosphere - the layer of air that sits high above the Earth. And this in turn feeds into the jet stream - the fast-flowing air current in the upper atmosphere that can drive the weather.

The results of this are dominantly felt above Europe, says Prof Lockwood.

"These are large meanders in the jet stream, and they're called blocking events because they block off the normal moist, mild winds we get from the Atlantic, and instead we get cold air being dragged down from the Arctic and from Russia," he says.

"These are what we call a cold snap... a series of three or four cold snaps in a row adds up to a cold winter. And that's quite likely what we'll see as solar activity declines."

So could this regional change in Europe have a knock-on effect on for the rest of the world's climate? And what are the implications for global warming?

Comment: The implications for global warming are: THAT IT'S OVER!Solar activity is so low that we may indeed be facing an ice age in the not too distant future:

Falling temperatures are giving climate alarmists chills

In a recent report by the UN's climate panel, scientists concluded that they were 95% certain that humans were the "dominant cause" of global warming since the 1950s, and if greenhouse gases continue to rise at their current rate, then the global mean temperature could rise by as much as 4.8C.

And while some have argued that ebbs and flows in the Sun's activity are driving the climate - overriding the effect of greenhouse gas emissions, the Intergovernmental Panel on Climate Change concludes that solar variation only makes a small contribution to the Earth's climate.

Prof Lockwood says that while UV light varies with solar activity, other forms of radiation from the Sun that penetrate the troposphere (the lower layer of air that sits above the Earth) do not change that much.

He explains: "If we take all the science that we know relating to how the Sun emits heat and light and how that heat and light powers our climate system, and we look at the climate system globally, the difference that it makes even going back into Maunder Minimum conditions is very small.

"I've done a number of studies that show at the very most it might buy you about five years before you reach a certain global average temperature level. But that's not to say, on a more regional basis there aren't changes to the patterns of our weather that we'll have to get used to."

But this weather would not be the only consequence of a drawn out period of inactivity, says Dr Green.

Polar lights - one manifestation of solar activity in the Earth's magnetosphere - may dim

"If the Sun were to get very quiet, one of the few things that would happen is that we'd have very few displays of the northern lights. They are driven by solar activity, and we'd miss out on this beautiful natural phenomenon," she explains.

However, there could be positive effects too.

"Solar activity drives a whole range of space weather, and these are ultimately effects on the electricity networks, on satellites, on radio communications and GPS on your sat-nav," she explains.

And while scientists cannot discount that the random bursts of activity may still occur, calmer periods of space weather would help to maintain the technological infrastructure that we rely so heavily on.

While the full consequences of a quietening Sun are not fully understood, one thing scientists are certain about is that our star is unpredictable, and anything could happen next.

"This feels like a period where it's very strange... but also it stresses that we don't really understand the star that we live with." says Prof Harrison.

"Because it's complicated - it's a complex beast."

Comment: Not complicated enough, if one is to spend time educating oneself on this topic.Here's what is known to us so far: The surface of the planet was, for a period of time (as reported in numerous stories back some 5/6 years ago) actually warming. There were reports of many hot-spots in various places, in some cases, hot enough to ignite. This is now being countered by surface cooling due to other factors, like global dimming/induction of colder air, etc. This heating of the lithosphere is probably due to the slowing of rotation which generates internal heat between the lithosphere and the mantle, and leads to increased volcanic eruptionsearthquakes,sinkholes, etc, and is probably also responsible for many of the strange sounds.

It is the upper atmosphere - the stratosphere - that is cooling and that is the reason for sun pillars, rings around the sun, double/triple/quadruple images of the sun, contrails, etc.

Volcanic dust does not heat the upper atmosphere by "trapping heat" in the stratosphere. That the stratosphere is colder and has dropped lower has been reported by scientists, though that information gets sidelined. The AGW folks would LOVE people to believe that nonsense.

Then, there is the comet dust/smoke in the upper atmosphere that further contributes to the cooling as you can see from the dramatic increase in noctilucent clouds.

At the same time that is going on, the quiescent sun and the earth's weakened magnetic field allow more cosmic radiation to reach thetroposphere where it forms cloud nuclei and increases precipitation from the increased evaporation from the oceans caused by the increasing heat within the earth caused by the slowing of rotation.

These are all the conditions for the initiation of an ICE AGE: heat at the lower levels, troposphere where "weather" takes place, extreme cold at the upper levels of the atmosphere, which can then create interesting effects including polar vortices.
