Has global warming really stopped?

Mark Lynas responds to a controversial article on newstatesman.com which argued global warming has s

On 19 December the New Statesman website published an article which, judging by the 633 comments (and counting) received so far, must go down in history as possibly the most controversial ever. Not surprising really – it covered one of the most talked-about issues of our time: climate change. Penned by science writer David Whitehouse, it was guaranteed to get a big response: the article claimed that global warming has ‘stopped’.

As the New Statesman’s environmental correspondent, I have since been deluged with queries asking if this represents a change of heart by the magazine, which has to date published many editorials steadfastly supporting urgent action to reduce carbon emissions. Why bother doing that if global warming has ‘stopped’, and therefore might have little or nothing to do with greenhouse gas emissions, which are clearly rising?

I’ll deal with this editorial question later. First let’s ask whether Whitehouse is wholly or partially correct in his analysis. To quote:

"The fact is that the global temperature of 2007 is statistically the same as 2006 as well as every year since 2001. Global warming has, temporarily or permanently, ceased. Temperatures across the world are not increasing as they should according to the fundamental theory behind global warming – the greenhouse effect. Something else is happening and it is vital that we find out what or else we may spend hundreds of billions of pounds needlessly."

I’ll be blunt. Whitehouse got it wrong – completely wrong. The article is based on a very elementary error: a confusion between year-on-year variability and the long-term average. Although CO2 levels in the atmosphere are increasing each year, no-one ever argued that temperatures would do likewise. Why? Because the planet’s atmosphere is a chaotic system, which expresses a great deal of interannual variability due to the interplay of many complex and interconnected variables. Some years are warmer and cooler than others. 1998, for example, was a very warm year because an El Nino event in the Pacific released a lot of heat from the ocean. 2001, by contrast, was somewhat cooler, though still a long way above the long-term average. 1992 was particularly cool, because of the eruption of a large volcano in the Philippines called Mount Pinatubo.

‘Climate’ is defined by averaging out all this variability over a longer term period. So you won’t, by definition, see climate change from one year to the next - or even necessarily from one decade to the next. But look at the change in the average over the long term, and the trend is undeniable: the planet is getting hotter.

Look at the graph below, showing global temperatures over the last 25 years. These are NASA figures, using a global-mean temperature dataset known as GISSTEMP. (Other datasets are available, for example from the UK Met Office. These fluctuate slightly due to varying assumptions and methodology, but show nearly identical trends.) Now imagine you were setting out to write Whitehouse’s article at some point in the past. You could plausibly have written that global warming had ‘stopped’ between 1983 and 1985, between 1990 and 1995, and, if you take the anomalously warm 1998 as the base year, between 1998 and 2004. Note, however, the general direction of the red line over this quarter-century period. Average it out and the trend is clear: up.

Note also the blue lines, scattered like matchsticks across the graph. These, helpfully added by the scientists at RealClimate.org (from where this graph is copied), partly in response to the Whitehouse article, show 8-year trend lines – what the temperature trend is for every 8-year period covered in the graph.

You’ll notice that some of the lines, particularly in the earlier part of the period, point downwards. These are the periods when global warming ‘stopped’ for a whole 8 years (on average), in the flawed Whitehouse definition – although, as astute readers will have quickly spotted, the crucial thing is what year you start with. Start with a relatively warm year, and the average of the succeeding eight might trend downwards. In scientific parlance, this is called ‘cherry picking’, and explains how Whitehouse can assert that "since [1998] the global temperature has been flat" – although he is even wrong on this point of fact, because as the graph above shows, 2005 was warmer.

Note also how none of the 8-year trend lines point downwards in the last decade or so. This illustrates clearly how, far from having ‘stopped’, global warming has actually accelerated in more recent times. Hence the announcement by the World Meteorological Organisation on 13 December, as the Bali climate change meeting was underway, that the decade of 1998-2007 was the “warmest on record”. Whitehouse, and his fellow contrarians, are going to have to do a lot better than this if they want to disprove (or even dispute) the accepted theory of greenhouse warming.

The New Statesman’s position on climate change

Every qualified scientific body in the world, from the American Association for the Advancement of Science to the Royal Society, agrees unequivocally that global warming is both a reality, and caused by man-made greenhouse gas emissions. But this doesn’t make them right, of course. Science, in the best Popperian definition, is only tentatively correct, until someone comes along who can disprove the prevailing theory. This leads to a frequent source of confusion, one which is repeated in the Whitehouse article – that because we don’t know everything, therefore we know nothing, and therefore we should do nothing. Using that logic we would close down every hospital in the land. Yes, every scientific fact is falsifiable – but that doesn’t make it wrong. On the contrary, the fact that it can be challenged (and hasn’t been successfully) is what makes it right.

Bearing all this in mind, what should a magazine like the New Statesman do in its coverage of the climate change issue? Newspapers and magazines have a difficult job of trying, often with limited time and information, to sort out truth from fiction on a daily basis, and communicating this to the public – quite an awesome responsibility when you think about it. Sometimes even a viewpoint which is highly likely to be wrong gets published anyway, because it sparks a lively debate and is therefore interesting. A publication that kept to a monotonous party line on all of the day’s most controversial issues would be very boring indeed.

However, readers of my column will know that I give contrarians, or sceptics, or deniers (call them what you will) short shrift, and as a close follower of the scientific debate on this subject I can state without doubt that there is no dispute whatsoever within the expert community as to the reality or causes of manmade global warming. But even then, just because all the experts agree doesn’t make them right – it just makes them extremely unlikely to be wrong. That in turn means that if someone begs to disagree, they need to have some very strong grounds for doing so – not misreading a basic graph or advancing silly conspiracy theories about IPCC scientists receiving paycheques from the New World Order, as some of Whitehouse’s respondents do.

So, a mistaken article reached a flawed conclusion. Intentionally or not, readers were misled, and the good name of the New Statesman has been used all over the internet by climate contrarians seeking to support their entrenched positions. This is regrettable. Good journalism should never exclude legitimate voices from a debate of public interest, but it also needs to distinguish between carefully-checked fact and distorted misrepresentations in complex and divisive areas like this. The magazine’s editorial policy is unchanged: we want to see aggressive action to reduce carbon emissions, and support global calls for planetary temperatures to be stabilised at under two degrees above pre-industrial levels.

Yes, scientific uncertainties remain in every area of the debate. But consider how high the stakes are here. If the 99% of experts who support the mainstream position are right, then we have to take urgent action to reduce emissions or face some pretty catastrophic consequences. If the 99% are wrong, and the 1% right, we will be making some unnecessary efforts to shift away from fossil fuels, which in any case have lots of other drawbacks and will soon run out. I’d hate to offend anyone here, but that’s what I’d call a no-brainer.

Mark Lynas has is an environmental activist and a climate change specialist. His books on the subject include High Tide: News from a warming world and Six Degree: Our future on a hotter planet.

They know where you live

Imagine your house being raided by armed police. That’s what happened to Mumsnet’s Justine Roberts after she fell victim to an internet hoaxer.

At around midnight on Tuesday 11 August 2015, a man dialled 999 to report a murder. A woman had been killed in her London home, he said, before hanging up without offering his name. A second call followed. This time, the man claimed to be the killer. He told the operator that he had now taken the woman’s children hostage at the Islington address. They were locked with him inside a room in the house, he said. The police responded with reassuring speed. Fifteen minutes later, eight officers, five of them armed with automatic weapons, accompanied by saliva-flecked dogs, arrived at the scene and took up position in neighbouring front gardens. When one officer banged on the front door of the house, the team was greeted, moments later, not by a masked murderer but by a blinking and bewildered au pair.

Justine Roberts, the woman whom the caller claimed to have killed, was in fact nearly 2,000 kilometres away – in Italy, holidaying with her husband and children. After explaining this to the police, the au pair called Roberts, who assumed that the incident was an unfortunate misunderstanding, one that could be unpicked after the vacation. It was no mistake. Roberts had been the victim of “swatting”, the term given to a false emergency call designed to bait an armed unit of police officers to storm someone’s home. It wasn’t until a few days later, as the family was preparing to return to London, that Roberts discovered that she had been the target of a planned and sustained attack, not only on her household, but also on her business.

Roberts is the founder of Mumsnet, the popular British internet discussion forum on which parents share advice and information. A few days before the swatting incident, members of 8chan, a chat room that prides itself on being an open, anonymous platform for free speech, no matter how distasteful, had registered accounts on Mums­net with the aim of trolling people there. When legitimate Mumsnet users identified and then ridiculed the trolls, some retreated to 8chan to plot more serious vengeance in a thread that the police later discovered. Roberts wasn’t involved in the online skirmish but, as the public face of the site, she was chosen as the first target.

After the initial armed response, Roberts’s perception was that the police were unconcerned about the swatting attack. “We were told that there was no victim, so there was not much that could be done,” she told me. The hoax caller, however, was not finished. In the days after the incident, there was chatter on Mumsnet and Twitter about what had happened. A Mumsnet user whom I will call Jo Scott – she requested anonymity for her own safety – exchanged heated messages with a hacker who claimed responsibility for the 999 call.

“It descended into jokes and silliness, like many things do,” Scott said. “I didn’t take it seriously when the hacker said he had big surprises in store.” She doesn’t believe that what happened next was personal. “I think I was just easy to find.”

A few days after police were called to Roberts’s home, Scott was in her bedroom while her husband was sitting downstairs playing video games. At 11pm, she heard a noise outside. “I looked out of the window and saw blue flashing lights in the street,” she recalled. “I could hear shouting but I didn’t pay it much notice.” Then she heard her husband open the front door. Police rushed into the house. An armed officer shouted upstairs, asking Scott if she was hurt. When she replied that she was fine, he told her to fetch her two young children: he needed to see them. Scott shook her sons awake, explaining, so as not to alarm them, that the police had come to show the boys their cars. As the three of them went downstairs, the officers swept up through the house, repeatedly asking if there were any weapons on the property.

“I was beyond confused by this point,” Scott said. “Everyone was carrying a gun. They had little cutaway bits so you could see the bullets. My eldest asked one of the officers if he could have a go on his gun and went to touch it.”

As Scott sat with an officer downstairs, she asked what had happened to her husband. “I later found out that the noises I’d heard were the police calling for him to come outside,” she said. “He dropped the PlayStation controller as he left the room. It was only later that we realised it’s a good job he did: in the dark, the controller might have looked like a weapon.”

Outside, Scott’s husband had been surrounded and arrested. Other police ­officers were on the lookout in the front gardens of nearby properties, having warned the couple’s neighbours to stay indoors, away from their windows. “One of the officers said it was beginning to look like a hoax,” Scott said. “Then he mentioned swatting. As soon as he said that word, I twigged that I’d seen the term that day on Twitter in relation to the Mumsnet hack.”

The term “swatting” has been used by the FBI since 2008. “Swat” is an acronym of “Special Weapons and Tactics”, the American police squads routinely called to intervene in hostage situations. It is, in a sense, a weaponised version of a phoney order of pizza, delivered as a prank to a friend’s home, albeit one that carries the possibility of grave injury at the hands of police. For perpetrators, the appeal is the ease with which the hoax can be set in motion and the severity of the results. With a single, possibly untraceable phone call, dialled from anywhere in the world, it is possible to send an armed unit to any address, be it the home of a high-profile actor whom you want to prank or that of someone you want to scare.

In America, where swatting originated, the practice has become so widespread – targets have included Tom Cruise, Taylor Swift, Clint Eastwood and the Californian congressman Ted Lieu – that it is now classed as an act of domestic terrorism. In the UK, where Justine Roberts’s was one of the first recorded cases, swatting is classed as harassment, though that may change if these and other forms of internet vigilante attacks, such as doxxing, become increasingly commonplace.

Doxxing involves the publication of someone’s personal details – usually their home address, phone numbers, bank details and, in some cases, email address – on the internet. It is often the prelude to swatting: after all, the perpetrator of a hoax cannot direct the police to the target’s home address until this is known. (During the week of the Mumsnet attacks, one of the perpetrators attempted to locate another target using their computer’s IP address, which can identify where a person is connected to the internet, often with alarming precision. Their calculation, however, was slightly out; police were called to a neighbour’s address.)

Though doxxing has a less dramatic outcome than swatting, the psychological effects can be just as severe. For victims – usually people who are active on the internet and who have outspoken opinions or who, in the eyes of an internet mob, have committed some kind of transgression – the mere threat of having their personal information made available on the web can cause lasting trauma. A Canadian software developer whose home address, bank details, social security number and email history were published online in 2014 told me that he now keeps an axe by his front door. “I still don’t feel safe here,” he said. “It’s terrifying.”

Christos Reid, a social media manager for a software company, was doxxed last year. Reid’s information came from a website he had registered seven years earlier. “I woke up one morning to find a tweet announcing my personal details,” he told me. When he asked the Twitter account holder to take down the address, he was told to commit suicide. Reid said he was “OK for about half an hour”; but then, after he went out, he broke down in the street. “I’ve become more paranoid,” he said. He no longer gives out business cards with personal information.

Reid lives in London, but at the time of the doxx he was attending an event in Nottingham, home to the British police’s largest cybercrime division. He was impressed with the police response, even though they told him that they had not heard of the term “doxxing” before. “I was interviewed by two separate people about my experiences who then compiled everything into a case file and transferred it to the Met. When I arrived home, an officer visited me to discuss what happened and my options.”

The policeman explained harassment law to Reid, and offered advice on how to improve security at his flat and what to do if someone hostile turned up at the address. Reid shouldered the repercussions of what had happened alone; no suspects were identified. A spokesperson for the Metropolitan Police similarly said that although detectives from Islington CID have investigated the swatting attacks made on Roberts and Scott, no suspects have been identified “at this time”, even as “inquiries continue”.

Doxxing may seem to be a mild form of harassment but it carries with it an implicit threat of impending violence; the worrying message is: “We know where you live.” Unlike swatting, which is always malicious, doxxing is sometimes viewed by its perpetrators as virtuous. In November 2014, hackers claiming to be aligned with the internet group Anonymous published personal information allegedly belonging to a Ku Klux Klan member from Missouri. The hackers said that their action was a response to the KKK’s threat to use lethal force against demonstrators in the city of Ferguson, Missouri, protesting against the killing of the unarmed black teenager Michael Brown by a white police officer. In January 2015 hackers claiming to be from Isis took over US Central Command’s Twitter account and posted information about senior military officers, including phone numbers and email addresses. In each case, those carrying out the doxxing believed, however mistakenly, in the virtue of their actions and hoped that the information could be used to bring punishment or ruin to the subject.

The term “doxxing” may be new but the practice is an old one. The Hollywood blacklist revealed the political beliefs and associations of actors and directors in the late 1940s as a way to invite shame, deny employment and dissuade others from following their example. “But it has become a lot easier to find people’s private details with the help of the internet,” Jeroen Vader told me. Vader owns Pastebin, a website that allows users to upload and distribute text documents, and where much of the personal data is anonymously uploaded and shared. “People post their private information on social networks,” he said. “A lot of people aren’t aware that their information is so easily available to others.”

In Justine Roberts’s case, the perpetrator may not even have needed to look at social networks to mine her personal information. “If you’re on the electoral roll, you’re easy to find,” she said. “There’s not much you can do to stop people getting hold of your data one way or another, whether it’s for nefarious reasons or simply to better advertise to you. We live in a world that is constantly trying to gather more information about us.”

Jeroen Vader said he has noticed an “upward trend” in the number of doxxing posts uploaded to Pastebin in recent months, but insisted that when someone uses the site’s abuse report system these offending posts are removed immediately.

Across social media companies, action is more often reactive than proactive. Victoria Taylor, a former director at Reddit, one of the largest community-driven websites in the world, said that the rule against publishing other users’ personal information has been “consistently one of the site’s most basic policies” and that “any violation of this rule is taken extremely seriously by the team and community”. Still, she was only able to recommend that victims of doxxing send a message to the site’s administrators. Similarly, when asked what a person can do to remove personal details that have been published without permission, a Twitter spokesperson said: “Use our help form.”

The spokesperson added: “There has def­initely been an overall increase in doxxing since 2006, both on Twitter and on the internet more generally.” She attributed this rise to the emergence of search engines such as Intelius and Spokeo, services designed to locate personal information.

The surge in the number of dox­xing and swatting attacks is in part a result of the current lack of legal protection for victims. Confusion regarding the law on doxxing is pervasive; the term is even not mentioned in either US or European law. In a tutorial posted on Facebook in 2013, the writer claims: “Doxxing isn’t illegal as all the information you have obtained is public,” and adds: “But posting of the doxx might get you in a little trouble.”

Phil Lee, a partner in the privacy, security and information department of Fieldfisher based at the law firm’s office in Silicon Valley, said that differing privacy laws around the world were part of the problem. “Various countries have laws that cover illegal or unauthorised obtaining of data. Likewise, some of the consequences of releasing that data, such as defamation or stalking, cover elements of what we now term doxxing. But there is no global law covering what is a global phenomenon.” Indeed, Roberts believes that her London address was targeted from America – the 999 call was routed through a US proxy number.

One challenge to creating a law on doxxing is that the sharing of personal information without permission has already become so widespread in the digital age. “If a law was to state something like, ‘You must not post personal information about another person online without their consent,’ it wouldn’t reflect how people use the internet,” Lee said. “People post information about what their friends and family members have been doing all the time without their consent.

“Such a law could have a potentially detrimental effect on freedom of speech.”

Lee believes that a specific law is unnecessary, because its potentially harmful effects are already covered by three discrete pieces of legislation dealing with instances where a person’s private information is obtained illegally, when that information is used to carry out illegal acts and when the publication of the information is accompanied by a threat to incite hatred. However, this does not adequately account for cases in which the information is obtained legally, and then used to harass the individual in a more legally ambiguous manner, either with prank phone calls or with uninvited orders of pizza.

Susan Basko, an independent lawyer who practises in California and who has been doxxed in the course of her frequent clashes with internet trolls, believes that the onus should be on the law, rather than the public. She points out that in the US it is a crime to publicise information about a government employee such as their home address, their home and cellphone numbers, or their social security number, even if the information is already online. “This law should apply to protect all people, not just federal employees,” she said. “And websites, website-hosting companies and other ISPs should be required to uphold this law.”

Basko said that doxxing will continue to increase while police have inadequate resources to follow up cases. For now, it is up to individuals to take preventative measures. Zoë Quinn, an American game designer and public speaker who was doxxed in 2014, has launched Crash Override, a support network and assistance group for targets of online harassment, “composed entirely of experienced survivors”.

Quinn, who spoke about the problem at a congressional hearing in Washington, DC in April last year, recently posted a guide on how to reduce the likelihood of being doxxed. “If you are worried you might some day be targeted,” she wrote, “consider taking an evening to stalk yourself online, deleting and opting out of anything you’re not comfortable with.”

Both Scott and Roberts have changed their privacy habits following the attacks. Scott is more careful about interacting with strangers online, while Roberts uses scrambler software, which ensures that she never uses the same password for more than one online site or service.

For both women’s families, the effects of their encounters with armed police have also lingered. When one day recently Roberts’s husband returned home early from work, the au pair called the police, believing it was an intruder. And Scott is haunted by what happened.

“What if my husband had made a sudden move or resisted in some way? What if my eldest had grabbed the gun instead of gently reaching for it? What if people locally believed that my husband did actually have guns in the house?” she asks. “I don’t think the people making these sorts of hoax calls realise the impact.”
