Reasons to be careful

Asteroids strikes, radiation and Rio+20.

So, yet another thing to worry about. It might not sound like news, but something big hit earth back in the 770s. Researchers looking at the radioactive carbon traces in tree rings from that period have discovered evidence of a burst of intense radiation between 774 and 775AD. It might seem churlish to worry about something that happened 1,200 years ago, given the problems that the Rio+20 summit this month clearly was not even going to begin to address. Yet warning us of potential danger is part of the scientist’s job description. What we do with that information is up to us.

The source of that 1,200-year-old radiation burst – potentially the harbinger of a much bigger catastrophe than climate change – is a mystery to scientists. A burst of radiation of this sort would normally come from a spectacular solar flare or a supernova. Taking the second option first, the exploding star in question would have been bright enough to be visible in daylight – a second sun that would have been recorded by contemporary historians. It should also have been spotted by today’s astronomers: the explosion would have created what looked like a new star. Stellar explosions recorded in 1006 and 1054 weren’t big enough to cause a spike in radiation but we have spotted the remnants in the sky.

The solar flare explanation has been ruled out, too. A flare occurs when the sun spits out a gob of plasma, a roiling gas of charged subatomic particles. If that is composed largely of protons and fired towards earth, its interaction with particles in Planet Earth’s atmosphere creates a burst of intense radiation. But it also creates the Northern and Southern Lights and, again, a radiation spike of this intensity would have produced a show spectacular enough to be recorded by historians.

On the downside, it would also have wiped out much of the ozone layer, causing biological chaos. The extra radiation and intense ultraviolet light usually absorbed by ozone would have mutated genomes and led to significant extinctions. There is no evidence that this occurred.

Why does it matter? Until we understand the source, we face a significant unknown. If it is somehow a threat from the sun, the threat is far bigger than we have known. Such a spike in radiation could be associated with the kind of solar activity that could melt many of the world’s power grids, sending civilisations howling back to the Stone Age.

We already know that things from space could hurt us badly. There’s about a one-in-five chance that, in the next 100,000 years, an asteroid strike will do as much damage as the one that wiped out the dinosaurs. There is no reason for complacency: it’s highly likely that, in the same time frame, a chunk of space rock roughly 400 metres in diameter will hit earth. The impact will be significant enough to devastate an area the size of France.

Too much in the sun

The tree-ring work, published in the journal Nature this month, suggests that scientists don’t yet have a handle on all the threats to humanity. But it will almost certainly be dismissed as another curiosity, not worth following up.

Maybe that is the right response. The conclusions were a result of interpreting the amounts of radioactive carbon – created by collisions between particles in the upper atmosphere – trapped in the tree rings.

Anyone with responsibility to act over threats to his or her citizens can choose to find weaknesses and uncertainties in the data, the extrapolations and the conclusions and thus justify a non-response. Just as our political leaders (or, rather, their delegations) will do in Rio. l

Rising crime and fewer police show the most damaging impacts of austerity

We need to protect those who protect us.

Today’s revelation that police-recorded crime has risen by 10 per cent across England and Wales shows one of the most damaging impacts of austerity. Behind the cold figures are countless stories of personal misery; 723 homicides, 466,018 crimes with violence resulting in injury, and 205,869 domestic burglaries to take just a few examples.

It is crucial that politicians of all parties seek to address this rising level of violence and offer solutions to halt the increase in violent crime. I challenge any Tory to defend the idea that their constituents are best served by a continued squeeze on police budgets, when the number of officers is already at the lowest level for more than 30 years.

This week saw the launch Chris Bryant's Protect The Protectors Private Member’s Bill, which aims to secure greater protections for emergency service workers. It carries on where my attempts in the last parliament left off, and could not come at a more important time. Cuts to the number of police officers on our streets have not only left our communities less safe, but officers themselves are now more vulnerable as well.

As an MP I work closely with the local neighbourhood policing teams in my constituency of Halifax. There is some outstanding work going on to address the underlying causes of crime, to tackle antisocial behaviour, and to build trust and engagement across communities. I am always amazed that neighbourhood police officers seem to know the name of every kid in their patch. However cuts to West Yorkshire Police, which have totalled more than £160m since 2010, have meant that the number of neighbourhood officers in my district has been cut by half in the last year, as the budget squeeze continues and more resources are drawn into counter-terrorism and other specialisms .

Overall, West Yorkshire Police have seen a loss of around 1,200 officers. West Yorkshire Police Federation chairman Nick Smart is clear about the result: "To say it’s had no effect on frontline policing is just a nonsense.” Yet for years the Conservatives have argued just this, with the Prime Minister recently telling MPs that crime was at a record low, and ministers frequently arguing that the changing nature of crime means that the number of officers is a poor measure of police effectiveness. These figures today completely debunk that myth.

Constituents are also increasingly coming to me with concerns that crimes are not investigated once they are reported. Where the police simply do not have the resources to follow-up and attend or investigate crimes, communities lose faith and the criminals grow in confidence.

A frequently overlooked part of this discussion is that the demands on police have increased hugely, often in some unexpected ways. A clear example of this is that cuts in our mental health services have resulted in police officers having to deal with mental health issues in the custody suite. While on shift with the police last year, I saw how an average night included a series of people detained under the Mental Health Act. Due to a lack of specialist beds, vulnerable patients were held in a police cell, or even in the back of a police car, for their own safety. We should all be concerned that the police are becoming a catch-all for the state’s failures.

While the politically charged campaign to restore police numbers is ongoing, Protect The Protectors is seeking to build cross-party support for measures that would offer greater protections to officers immediately. In February, the Police Federation of England and Wales released the results of its latest welfare survey data which suggest that there were more than two million unarmed physical assaults on officers over a 12-month period, and a further 302,842 assaults using a deadly weapon.

This is partly due to an increase in single crewing, which sees officers sent out on their own into often hostile circumstances. Morale in the police has suffered hugely in recent years and almost every front-line officer will be able to recall a time when they were recently assaulted.

If we want to tackle this undeniable rise in violent crime, then a large part of the solution is protecting those who protect us; strengthening the law to keep them from harm where possible, restoring morale by removing the pay cap, and most importantly, increasing their numbers.

Holly Lynch is the MP for Halifax. The Protect the Protectors bill will get its second reading on the Friday 20th October.
