Who’s afraid of the big, bad virus? Perils from beneath the Arctic ice

The melting of Arctic permafrost is reawakening millennia-buried pathogens. But it’s the release of methane we should be more worried about.

This month, we learned that the melting of permafrost in Arctic regions is giving a new lease of life to hitherto unknown viruses. These have been buried in the ice for thousands of years but rising global temperatures are now thawing some of them out. As the melting continues, who knows what dangerous pathogens might be released?

The response from virologists was generally along the lines of: “Don’t panic.” That’s not quite the right reaction. There is something to worry about here.

The big discovery was the pithovirus, now confirmed as the world’s largest virus. It was last active 30,000 years ago and the French team that reactivated it managed to get the virus to infect amoebae. The researchers claim to have ruled out the possibility of human beings becoming infected with pithovirus but there are reasons to be sceptical.

A few years ago, the same French biologists said they were confident that a previous virus discovery, the mimivirus, could not infect people. But it also infected amoebae – and blood samples taken from one of their lab technicians, who had come down with mild pneumonia, were found to contain mimivirus antibodies. In other words, it seems they were wrong. Just because the researchers haven’t managed to infect human cells with the new virus, that doesn’t mean it couldn’t happen.

However, that’s not what we should be worried about. Neither should we be too concerned that the receding permafrost could bring us into contact with other potentially dangerous viruses. It is possible that the tundra contains deep-frozen organisms that could be harmful to people; plans to drill for oil and gas in those regions could create new threats. Yet you could say the same of exploring the oceans. Every litre of seawater contains roughly ten billion microbes and 100 billion viruses. Most are not in our catalogues.

It is even possible that this is a good thing. We are learning how to harness the peculiar abilities of viruses to deliver gene therapy and even fight cancer. Something called a reovirus, for instance, is being tested against tumours; it attacks cancerous cells but leaves normal cells untouched.

Other viruses are proving effective at smuggling healthy human DNA into diseased organs, enabling us to cure some cases of partial blindness, for example. Having a new set of viruses to play with might prove useful.

What we should be concerned about is far more straightforward. The threat from a newly released virus is nothing compared to the threat from newly released molecules of methane. Atmospheric methane accelerates warming about 25 times faster than carbon dioxide. There is roughly 400 billion tonnes of methane trapped in permafrost. As global temperatures rise, the ground melts and the gas is released.

There have been very few studies into the risks posed by melting permafrost (pdf). Last summer, however, a team of economists and polar science researchers warned that it is an “economic time bomb”. If there is a sudden release of methane – and no one knows if it will be a slow leak or an enormous belch – the effects will include flooding, extreme weather events and, consequently, a huge downturn in agricultural production. Researchers estimate that the economic impact of the tundra melting could be as much as $60trn.

Resurrected monster viruses make great headlines but the creep of unmitigated climate change is far more likely to do the serious damage.

“I begged him to come home”: Breaking the taboo around texting the dead

Many people text dead loved ones to cope with their grief – but trouble arises when they get an unexpected reply. 

A month after Haley Silvestri’s dad died from a heart attack, she texted him begging him to come home. In the middle of the night Silvestri’s 14-year-old sister had found their father, with his lips and mouth blue, lying on the kitchen floor. “There was nothing there anymore, just a dead body,” Silvestri says. “My father had his first heart attack months before and seemed to be doing OK. Then, this happened.”

In the very first episode of CSI Miami’s seventh season, the protagonist – Horatio Caine – fakes his death. For the first 15 minutes of the episode, the viewer believes the character is truly dead, as the camera lingers on Horatio’s body face down on the tarmac.

Silvestri and her father used to enjoy watching the show together. After he had passed and she realised she would never see her “best friend” again, she picked up her phone. “I texted my dad begging him to come home,” she says. “I begged my dad to please be ‘pulling a Horatio’.”

"My heart was broken and I was bawling as I texted her over and over" 

In texting her father after he had died, Silvestri is by no means unusual. No official figures exist for the number of people who use technology to message their deceased loved ones, but Sara Lindsay, a professional counsellor, clinical supervisor, and trainer, says it is “more common than we think”.

“I see it as a modern and contemporary part of the grieving process,” she says. “I think in a way it's very similar to visiting a graveside, in that the bereaved are reaching out, particularly in the early days, because it takes a long time for people to process the reality that this person has now gone.”

Karlie Jensen, 18, texted her friend immediately after she found out she had died in a car accident. “I texted her as soon as I woke up to the news from my mom that she had passed. My heart was broken and I was bawling as I texted her over and over waiting for a text saying it wasn't her, that my mom didn't know all the facts, and maybe she was just hurt.” Jensen also called her friend and begged her to respond. “I did it because I couldn't let go and couldn't accept she was gone from my life forever,” she says. Karlie continued to text her friend while also calling her voicemail in order to hear the sound of her speaking again.

After her first text to her deceased father, Silversti also began texting him once a week. She fell into depression, and on her worst days messaged the number. “I think it helped initially because it felt like I was personally writing a note to him, that I knew he only was gonna see,” she says. “I did it because it was my attempt at pretending he was still here and could text me back.”

Lindsay, who has over a decade’s experience of bereavement counselling, emphasises that this behaviour is in no way unhealthy. “I think on the whole it's a very healthy part of grieving, particularly in the first year where the bereaved faces agonising days without their loved ones,” she says. “There is just so much loss and change in their life that’s out of their control, I see this aspect of texting as a small way of being able to reach out and alleviate that pain. That person is suddenly now not there but how they feel about that person hasn't changed.”

"I was going through my phone and I saw his number – I wanted to delete it, but I hesitated I thought maybe I could send a text"

Despite being normal, however, using technology to talk to the dead is a behaviour we rarely – if ever – hear anything about. If the words “texting the dead” make it into the media, they are usually followed by a far more sensationalist “and then they text back!!!!”. Yet although messaging the deceased is popularly seen as the stuff of horror movies and trashy headlines, in reality it is simply a new, modern way to grieve.

“The first time I texted him I was on my bus on the way to school,” says now-20-year-old Dylan Campbell about his cousin Josh, who passed away from leukaemia. “I didn't have many friends so I had no one to talk to. I was going through my phone and I saw his number – I wanted to delete it, but I hesitated I thought maybe I could send a text and someone would reply or I would get something out of it.”

Campbell continued to send his cousin texts for a few weeks, “kind of like a diary”. He says he did so because he regretted not seeing Josh more up until his death, and “had a lot of things to say” that he’d never had the chance to. Linsday says texting in this way is a very healthy way of completing unfinished business. “There might have been something they've never said to their loved one that they want to be able to say and texting is a very normal place to do that.”

"Begging for a dead person to reply to you hurts since you won't ever get what you want in return"

Nonetheless, Lindsay notes that texting the dead can become unhealthy if grief becomes “stuck”, and the texting replaces normal communication or becomes a long term compulsion. Unlike Silvestri and Campbell, Jensen continued to text her friend in the hopes she would text back. She admits now that she was in denial about her death. “Begging for a dead person to reply to you hurts since you won't ever get what you want in return” she says. “I don't know if it helped trying to contact her or hurt worse because I knew I'd never get a reply. I wanted a reply.”

Quite frequently, however, this reply does come. After a few months – but sometimes in as little as 30 days – phone companies will reallocate a deceased person’s phone number. If someone is texting this number to “talk” to their dead loved one, this can be difficult for everyone involved.

“This story doesn't have a happy ending,” says Campbell. “After a few months someone from that number called me and yelled at me to stop bothering them – it was really heart breaking.” When Silvestri texted her father to wish him a happy birthday (“Saying I hoped he was having a great party up in heaven”) someone replied telling her to never text the number again. “I was pissed off,” she says. “Just block my number if it was that serious. This was a form of therapy I needed and it got taken away because someone couldn’t understand my hurt.”

Indeed, behind the sensationalist tabloid headlines of "texting back" is a more mundane - and cruel - reality of pranksters pretending to be the dead relatives come back to life.

"Visiting a grave is a clear recognition that the person visited does not exist in the normal day-to-day state of life, whereas texting allows for a suspension of that reality"

Silvestri, Jensen, and Campbell have never spoken to anyone else about the fact they texted their dead loved ones. Lindsay says that a fear of seeming “mad” combined with cultural phenomena – like the British stiff upper lip – might make people reluctant to speak about it. There is also a stigma around the way much of our modern technology is used in daily life, let alone in death.

This stigma often arises because of the newness of technology, but Christopher Moreman, a philosophy professor and expert on death and dying, emphasises that texting the dead is simply a modern iteration of many historical grieving practices – such as writing letters to the dead or talking to them at their graves. “I don't think the process of grieving is much changed, even if new modes of grieving come about due to new technologies,” he says. In fact, if anything, the differences between old and new ways of grieving can be positive.

“One important difference is in the sense of proximity,” explains Moreman. “I can text a loved one from anywhere in the world, but I can only visit their grave in one specific location. In another way, texting has the same structure whether I am texting someone who is alive or dead, so a sense of proximity also exists in the experience itself.

“Visiting a grave is a clear recognition that the person visited does not exist in the normal day-to-day state of life, whereas texting allows for a suspension of that reality. Some people may complain that new technologies allow us to ignore the reality of death, but there isn't any evidence that one way of grieving is more or less healthy than another.”
