Is our Sun falling silent?

Comment: Though not as crudely corporatised as the US media, the BBC is similarly compromised when it comes to objective reporting. It is an arm of the Establishment as we have seen with the Jimmy Savile debacle and endless human-influenced global warming bias. Here, they really need to get up to speed on the idea of climate change as a cyclic phenomenon including both global warming and global cooling periods. 

It's only "baffling scientists.." if they happen to have bought into the theory of anthropocentric global warming.

In 2007, William Livingston and Matthew Penn were talking about all this in their paper "Sunspots may vanish by 2015".  The potential effects on climate were also discussed in: " The Chilling Stars: A New Theory of Climate Change", by Henrik Svensmark and Nigel Calder. Yet the  BBC still have their mandate to push the highly flawed and politicised "scientific consensus" of the minor effects of man-made CO2 emissions...

Anyway, at least the BBC has decided to acknowledge that the Sun can affect the climate. I suppose that's something...

The Sun's activity may be falling faster than at any time in 10,000 years

"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.


The Sun should be at the peak of its activity - bursting with flares and 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.
