Drastic and immediate cuts in carbon emissions, as advocated by most of the green lobby, are an expe

There is a disturbing tendency among many in the climate debate today to deride as "deniers" anyone who does not advocate making huge and immediate carbon cuts. The framing began nearly a decade ago with discussions about the science of climate change. People who questioned the link between carbon emissions and warming were branded "deniers".

The semantic similarity to Holocaust denial was made overt when several prominent environmental campaigners suggested a need for Nuremberg-style trials for their opponents. Such rhetoric was deeply unfortunate. However, one could at least argue that the resulting fiery debate achieved one positive thing: it played a role in rousing most climate scientists to join together to underscore the message that global warming is largely man-made.

We have long since moved on from any mainstream disagreements about the science of global warming. Now, the crucial conversation is about the economics of our response. Today, the labels "denier" and "sceptic" are hurled at anyone who does not fervently argue for drastic, immediate carbon cuts. There is no possible justification, given that so many climate economists - the specialists in this field - recommend very different policies from those being advocated by the zealous carbon cut lobbyists.

In my book, first published in Danish in 1998, and then in English as The Skeptical Environmentalist in 2001, I wrote that man-made global warming exists. I could not have been clearer; the introduction to the section on climate change states: "This chapter accepts the reality of man-made global warming." My position has not changed. Thus, when I am labelled a "long-time climate sceptic" or "climate change denier" by
bloggers and activists, it is not based on any suggestion I have ever declared that the science of global warming is wrong. Rather, it is the campaigners' heated response to my pointing out that drastic carbon cuts don't make sense and that smarter policy responses should be considered.

It is understandable that emotions run high in such a defining discussion. I can appreciate, even in those who disagree with me, a moral intent to do good for humanity. But I cannot see how responding to empirical economics with slander will ever be helpful. Much worse than that, I believe that ignoring - or, indeed, denying - basic economic reality is a shoddy way of helping the planet.

In July, the G8 agreed to make carbon emission cuts to limit global warming to no more than 2°C above pre-industrial levels. This would be the most costly public policy humanity has ever enacted.

The Copenhagen Consensus Centre recently asked top climate economists to explore the benefits and costs of different responses to global warming, to prompt a discussion about the solutions that would have the biggest impact on climate for the lowest cost. We convened a second stellar group of top economists, including three Nobel laureates, to examine independently all of the research and rank the proposals in order of desirability.

One research author, the prominent climate economist Professor Richard Tol, who has been a contributing, lead, principal and convening author for the IPCC, strikingly showed that grand promises of drastic, immediate carbon cuts are a hugely expensive way of doing very little good. Reducing emissions by 80 per cent by mid-century (to achieve the 2°C goal) would avert much of the expected damage of global warming; based on conventional estimates, it would avoid climate damages of about £1.9trn a year by 2100. However, the cost of this would be a reduction in growth - particularly damaging to the world's poor - to the tune of around £25trn a year. Moreover, the costs would come much sooner than the benefits. Every pound spent on this grand plan would achieve twopence worth of good.

Put starkly: drastic carbon cuts would hurt much more than climate change. Cutting carbon is extremely expensive, especially in the short term, because the alternatives to fossil fuels are few and costly. Without feasible alternatives, we just hurt growth, which would be especially damaging for countries such as Brazil, China and India, dependent on fossil fuels to lift millions out of poverty.

It is important to emphasise that Tol's figures are based on projections from all the major economic energy models of the Stanford Energy Modelling Forum. Around half of the models found it impossible to achieve the target of keeping temperature rises lower than 2°C with carbon cuts. The £25trn price tag is optimistic because it comes only from the models that project the target is even possible.

The cost assumes that politicians everywhere in the world would, throughout the entire century, make the most effective, efficient choices possible to reduce carbon emissions. Dump that far-fetched assumption and the cost could be ten or even 100 times higher.

The Copenhagen Consensus on Climate's expert panel considered Tol's research - along with other proposals for responses to global warming - and concluded that drastic carbon cuts would be the poorest approach. The economic lessons are underpinned by real-world experience. In Rio de Janeiro in 1992, politicians from wealthy countries promised to cut emissions by 2000, but did no such thing. In Kyoto in 1997, leaders promised even stricter reductions by 2010, yet emissions have kept increasing unabated. It is little wonder that politicians are backing away from promising that they will be able to broker a new deal on carbon cuts in Copenhagen this December.

Despite the shambles of the Copenhagen negotiations, many carbon cut campaigners refuse to discuss alternative approaches. By dismissing critics as "deniers" and "sceptics", they commit the planet to the poorest policy choice - and one with very little chance of succeeding in controlling temperature rises. We could and should do better. The expert panel of Nobel laureate economists, working for the Copenhagen Consensus on Climate, revealed smarter solutions.

The panel recommended immediate research into climate engineering technology and a substantial increase in research and development of green energy alternatives. The two approaches complement each other. Climate engineering has the advantage of speed. There is a significant delay between carbon cuts and any temperature drop - even halving global emissions by mid-century would barely be measurable by the end of the century. And making green energy cheap and prevalent will also take a long time. After all, electrification of the global economy is still incomplete after more than a century of effort.

Climate engineering has a lot of potential as a way for us to buy more time - but it does not appear to be a long-term answer. We could gain time to ensure that we can shift sustainably and efficiently away from reliance on fossil fuels, which requires the investment in researching alternatives to these fuels.

Many of us fear climate engineering. But the groundbreaking research paper by Eric Bickel and Lee Lane at the University of Texas - one of the first studies of the costs and benefits of these technologies - offers compelling evidence that a tiny investment in climate engineering might be able to reduce as much of global warming's effects as trillions of pounds spent on carbon emission reductions.

The most attractive technology Bickel and Lane examine appears to be marine cloud whitening, where boats spray seawater drop-lets into clouds at sea to make them whiter and thus reflect more sunlight back into space, so reducing warming. This augments the natural process whereby sea salt from the ocean is whipped up and provides cloud condensation nuclei. Marine cloud whitening would not lead to permanent atmospheric changes, and could be used only when needed.

The researchers conclude, remarkably, that we might be able to cancel out this century's entire global warming with 1,900 unmanned ships spraying seawater mist into the air, at a total cost of about £6bn. When the benefits from averted warming are calculated, this is the equivalent of doing more than £2,000 worth of good with every pound spent.

President Barack Obama's science adviser, John Holdren, has said that climate engineering has "got to be looked at", and many prominent scientists agree. Concerns about the ramifications of this technology are a reason to research now to identify all of the limitations and risks. If it turns out that this is not a feasible or sensible approach, we need to have that information as soon as possible.

Marine cloud whitening would obviously not solve every aspect of global warming. But it would achieve more, much faster, than any plausible carbon cuts could ever do, and at a fraction of the price. If we are concerned with solving global warming, then we have a moral obligation to research what we could achieve with this technology.

But there is no point in using climate engineering to buy more time if we do not use it effectively. Since politicians started negotiating carbon agreements, we have wasted nearly 20 years without making any significant progress in reducing global warming. Focusing primarily on how much carbon to try to cut through taxes, rather than on how to achieve this technologically, puts the cart before the horse.

Global energy demand will double by 2050, according to research by the respected climate change economists Chris Green and Isabel Galiana from McGill University in Montreal. Use of fossil fuels remains vital for our development, prosperity and survival. Alternative sources of energy are unfortunately far from ready for widespread use. Green and Galiana show that, to reduce carbon emissions by three-quarters by 2100 while maintaining reasonable growth (a less ambitious goal than the G8's), non-fossil-fuel-based sources of energy will have to be an astonishing two and a half times greater in 2100 than the total level of global energy consumption in 2000.

If we continue on our current path, technological development will not be anywhere near significant enough to make non-carbon-based energy sources competitive with fossil fuels on price and effectiveness. Green and Galiana examine the state of non-carbon-based energy today - nuclear, wind, solar, geothermal, etc - and find that, taken together, alternative energy sources would get us less than halfway towards a path of stable carbon emissions by 2050, and only a tiny fraction of the way towards stabilisation by 2100. The technology will not be ready in terms of scalability or stability. In many cases, there is still a need for the most basic research and development. We are not even close to getting this revolution started.

Current technology is so inefficient that we would have to blanket most countries with wind turbines to power everybody's needs, and even then we would have the problem of storage when the wind doesn't blow.

Many environmental campaigners lauded China's ambition to create "green cities", powered by huge wind farms. But China plans to build dozens of new coal-fired power plants for these cities, too: otherwise, there will be blackouts every time there is not enough wind. The vast majority of Chinese cities will still rely on electricity from coal.

If governments try to cut carbon through taxes and trading schemes without effective replacements, we will make virtually no difference to climate change in the future, while in the shorter term there will be significant damage to economic growth.

Public funds on research and development also need to increase dramatically. We cannot rely on private enterprise alone. As with medical research, early innovations will not reap significant financial rewards, so there is no strong incentive for private investment today. While many of us assume that green research and development must have increased dramatically over the past decade, the actual numbers from the International Energy Agency show that not only has this spending not risen, but it has actually declined significantly since the early 1980s.

Policymakers should abandon fraught carbon reduction negotiations and instead make agreements to invest in research and development to get this technology to the level it needs to be. Provided that this spending doesn't go into subsidising existing, inefficient technology, but is instead put towards promoting innovation, this would have a far greater chance of tackling climate change - and a far greater chance of political success.

The biggest carbon emitters of the 21st century, including India and China, are understandably unwilling to sign up to tough, costly emission targets. They would be much more likely to embrace a cheaper, smarter and more beneficial path of innovation. Ultimately, we will not succeed politically or economically in tackling climate change by making fossil fuels so expensive that nobody will use them. However, if we forge onwards with dramatically increased research and development, towards the middle of the century we could make green energy so cheap that everyone will use it.

Discussions about solving the planet's problems will always be emotional. But they should also be reasoned. The most reasonable response to global warming is to change our course and focus on an approach that would actually work.

Brothers in blood: how Putin has helped Assad tear Syria apart

The Syrian catastrophe has created the worst humanitarian crisis since the end of the Second World War. And the world watches helplessly as Putin and Assad commit war crimes.

Sometimes we know the names. We know Omran Daqneesh, the five-year-old boy who, covered in mud and dust, was pictured on the back seat of an ambulance in the aftermath of an air attack. We know his name because pictures and a video of him were released on social media and travelled around the world. The outrage that followed was widespread and sincere, the image of the dazed little boy seeming to symbolise the greater plight of the beleaguered residents of Aleppo. But then the moment passed. Few will know that a few days later doctors announced that Omran’s elder brother Ali, who was injured in the same air strike, had died from his injuries. He was ten.

Sometimes we know the names of the babies pulled from the rubble of collapsed buildings – occasionally alive, but often dead; or the names of the children weeping over lost parents; or the women grieving over lost husbands and children; or the elderly simply waiting (and sometimes wanting) to die.

We know Bana Alabed, the seven-year-old girl trapped inside Aleppo whose Twitter account has gone viral in recent weeks. “Hi I’m Bana I’m 7 years old girl in Aleppo [sic],” reads the on-page description. “I & my mom want to tell about the bombing here. Thank you.”

A series of pictures depicts Alabed and her mother, Fatemah, struggling to live as normal a life as possible, one showing the little girl sitting at an MDF desk with a book. Behind her, in the corner, is a doll. “Good afternoon from #Aleppo,” says the caption in English. “I’m reading to forget the war.”

The conflict, however, is never far away. Alabed, whose mother taught her English, has repeatedly tweeted her own fears about dying, followed by stoic messages of defiance whenever the immediate threat of an impending air strike passes. On the morning of 3 October, her words were simply: “Hello world we are still alive.” On 17 October, Fatemah tweeted: “The airstrikes ended in the morning, all the last night was raining bombs.”

But in most cases we never know the names of the victims of air assaults led by Presidents Bashar al-Assad and Vladimir Putin. One of the most haunting images to emerge in recent weeks was that of a mother and child, killed while sleeping in the same bed. The scene had an eerily preserved-in-amber feel to it: a snapshot of snatched lives, frozen in the act of dying. Pictures of ruined buildings and distraught civilians have become routine now, holding our attention briefly – if at all.

As many as 500,000 people are believed to have been killed since the beginning of the Syrian uprising in early 2011. According to a report released in February this year by the Syrian Centre for Policy Research, a further 1.9 million have been wounded. Taken together, those figures alone account for 11.5 per cent of Syria’s pre-revolutionary population. Combine that with the number of Syrians who have been displaced – more than ten million (almost 50 per cent of the population) – and the sheer scale of the disaster becomes apparent.

The conflict has become the worst humanitarian crisis since the Second World War. Today it centres on Aleppo, in north-west Syria, one of the oldest continuously inhabited cities in the world, and a cradle of human civilisation. Various conquerors from the Mongols to the French have fought battles there but none, so it would seem, has been quite as ruthless or committed to the city’s annihilation as Bashar al-Assad.

Aleppo remains the most significant urban centre to have been captured by the anti-Assad rebels, most of whom will (by now) be strongly influenced by an Islamist world-view. Indeed, the most prominent fighting groups on the rebel side are overwhelmingly Islamist in their troop composition and beliefs, a sad marker of Western failures to support secular forces that led the anti-regime resistance in the incipient phases of the uprising.

Yet Aleppo remains too important to fail. Although rebel forces succeeded in capturing only half of the city – the western side remained firmly in the control of the regime – the symbolism of anti-Assad forces holding ground in Syria’s second city (which also served as the country’s economic hub) has buoyed the rebel movement.

Assad is more brazen and bullish than at any other point since eastern Aleppo fell into rebel hands in July 2012. That optimism is born of a strategy that has already worked in other parts of the country where the regime’s troops have slowly encircled rebel-held areas and then sealed them off. Nothing can leave, and nothing can enter. Once the ground forces seal off an area, an aerial campaign of barrel bombs and missile attacks from both Syrian and Russian fighter jets inevitably follows.

To get a sense of just how terrible the aerial campaign has been, consider that the United States accused the Russian air force of potential war crimes when a UN aid convoy was bombed just west of Aleppo last month. It was carrying food and medicines when it was hit. Since then, the UK and France have said that Russia’s bombardment of Aleppo amounts to a war crime.

Putin’s support has come as a boon to Assad ever since Russia formally entered the conflict in September 2015. Despite his administration already using Iranian forces and aligned groups such as the Lebanese Shia militia Hezbollah, rebels had continued to make significant gains throughout the early months of 2015. The most important of these was the capture of Idlib city, 40 miles from Aleppo, which presented Assad with two problems. The first was that it dented the official narrative of revanchist military successes by his forces. The ­second was that it handed the rebels power in a province adjoining Latakia Governorate in the west, where Syria’s Alawites are largely concentrated (Russia has an airbase in an area south-east of the city of Latakia). The Alawites are a heterodox Shia sect to which the Assad family belongs, and which forms the core of their support base.

Keen to reverse these gains – and others made elsewhere – Assad enlisted Putin, given Russia’s long-standing interests in, and ties to, Syria. The Kremlin has long regarded Syria as an important ally, and has served as the country’s main arms supplier for the past decade. There are important assets to preserve, too, such as the Russian naval base in the port city of Tartus on the Mediterranean, which was first established during the Soviet era.

For his part, Putin has felt emboldened by events. The world is changing – not just in the Middle East and North Africa, where the
contours of power continue to be recast, but also closer to home in Ukraine, where the pro-Russian president Viktor Yanukovych was overthrown in 2014.

The West is still haunted by the 2003 invasion of Iraq and has been reluctant to be drawn too deeply into the Syrian War. In 2013, the Assad regime used chemical weapons against its own people. This was a violation of President Barack Obama’s so-called red line against the use of chemical weapons, but no retaliatory action came and there was nothing to prevent the Kremlin from using force to shape events in Syria – as it had done in Ukraine.

All of this has marked a new phase of brutality in a conflict already noted for its barbarism. Civilians who avoid death from combined Russo-Syrian air assaults suffer under Assad’s strategy of “starve or submit”, in which supplies are withheld from besieged areas, slowly choking off those ­inside. It has been used to devastating effect against civilians in towns such as Madaya and in Daraya, on the outskirts of Damascus, both of which fell to government control after being sealed off from the outside world for several years. Such a strategy is not designed to deliver quick victories, however. Consider how the residents of Daraya defied Assad’s forces for four years before capitulating in August 2016.

Assad and his allies (Putin, Iran, Hezbollah) have decided to punish and brutalise, deliberately, civilian populations in rebel-held areas. To invert the famous aphorism attributed to Chairman Mao, they hope to dredge the sea in which the revolutionaries swim. And so, it is the 300,000 residents of eastern Aleppo who must suffer now.




It’s easy to lose track of precisely what is happening in the Syrian War as parcels of land swap hands between rebels and the regime. Assad’s forces first began encircling Aleppo at the start of July this year and succeeded in imposing a siege by the middle of that month, after cutting off the last of two rebel-controlled supply routes into the city. The first was the Castello Road, which leads from the town of Handarat into the north-western part of ­rebel-controlled territory. The second route, via the Ramouseh district (which led into the south-western end of the city), had already been sealed off.

The closure lasted for roughly four to five weeks before the rebels re-established access. Aleppo is too important for them, and the siege has forced various groups to work together in breaking it. The effort was led by Jaish al-Fateh (JaF, the “Army of Conquest”), an umbrella group and command structure for several of the most prominent jihadist and Islamist groups operating in northern Syria. JaF also co-ordinated the Idlib military campaigns. One of its key members is Jabhat Fateh al-Sham (JFS, “the Syrian Conquest Front”), which was previously known as Jabhat al-Nusra (JaN or “the Supporters’ Front”) and was recognised as al-Qaeda’s official chapter in Syria.

Several months before the regime began its assault on Aleppo, rebel groups in the north recognised the deteriorating situation there, stemming principally from Russian air strikes. As a result, al-Qaeda urged the various factions to merge and work together to counteract not just Assad, but also Putin. Even the global leader of al-Qaeda, Ayman al-Zawahiri, issued a speech last May titled “Go Forth to Syria”, in which he called on all fighting groups to unite in order to consolidate their control across the north. This opened the way at the end of July for Jabhat al-Nusra to declare that it was formally severing its links with al-Qaeda. It “rebranded” as Jabhat Fateh al-Sham.

There are two reasons for doing this. The first is to erode partisanship among the Islamist groups, forcing them to set aside differences and narrow their ambitions in favour of the greater goal – in this case, the breaking of the siege of Aleppo, while also deepening rebel control across the north. The second aim of rebranding is to win popular support by portraying themselves as fighting in the service of ordinary civilians.

Groups such as JFS and others are succeeding in both of these goals. Responding to the abandoned and assaulted residents of Aleppo, they have repeatedly demonstrated their commitment to alleviating the humanitarian crisis. Much of their messaging echoes this theme. The group’s English-language spokesman is Mostafa Mahamed, an Egyptian who previously lived in Australia. “[JFS] is deeply embedded in society, made up from the average Syrian people,” he explained on Twitter, after the group decoupled from al-Qaeda. “We will gladly lay down our lives before being forced into a situation that does not serve the people we are fighting for . . . jihad today is bigger than us, bigger than our differences.”

It is indisputable that this ethos of “fighting for the people” has endeared the group to civilians living in besieged areas – even when those civilians don’t necessarily agree with the full spectrum of its religious beliefs or political positions. That goodwill was only reinforced when the group helped break the siege of Aleppo (in which approximately 500 rebels were killed) in August, if only for a few days. Assad reasserted control within a week, and entrapped the residents again in the middle of that month. The rebels are now planning how to break the siege decisively, but have not yet launched a major counteroffensive.




A freelance American journalist and film-maker, Bilal Abdul Kareem, who has reported on rebel movements inside Syria more intimately than most, has found himself among those trapped inside eastern Aleppo since the siege was restored seven weeks ago. “We came here expecting a two- or three-day trip,” he told me during an interview over Skype.

Life inside is becoming insufferable for civilians, Abdul Kareem said; every building is potted and scarred by shrapnel damage. Those whose homes remain standing are the lucky ones. “Your day consists of nothing,” he said. “There’s no work, there’s no fuel, no industrial zone, no food to sell. ­People sit around and chit-chat, drink tea, and that’s all they do.”

Food supplies are already running low, with most people limiting themselves to basics of chickpeas and groats – crushed grains such as oats or wheat. Sealed off from the rest of the world, those inside preoccupy themselves with survival and wait for the next wave of attacks.

It is tempting to ask why the inhabitants of Aleppo did not flee when they had the chance. Indeed, the Assad regime routinely accuses the rebels of preventing civilians from leaving besieged areas, though there is no evidence to support this view. On 17 October Russia and the Syrian regime said they would halt their bombardment for eight hours on 20 October to allow rebels and civilians to evacuate the city.

In truth, what choice do the civilians have? Most do not trust Assad and they are therefore unwilling to move into regime-administered areas. The alternative is to become refugees, with all the uncertainties and trials associated with that. For instance, refugees have found themselves subject to sectarian violence in Lebanon, and they have few opportunities to find employment in Lebanon, Turkey or Jordan, the three countries where most of the fleeing Syrians have found shelter.

For them, merely to exist in rebel territory is an act of defiance, which is precisely why Assad’s forces make no effort to distinguish between combatants and civilians in rebel areas. To be present is a crime.

The effects of this have been devastating. A spokesman for the Syrian American Medical Society told Middle East Eye, an online news portal, that in July, Syrian and Russian jets had hit medical facilities in rebel-held territory every 17 hours.

Only a few hospitals and medical staff remain. The physical conditions are primitive and perilous. Doctors work in makeshift facilities – a former flat, a commercial garage – which makes them unable to provide anything beyond basic emergency care. In-patient facilities are non-existent, not just because of high demand from those newly injured in fresh attacks, but also from fear that the facility itself will be targeted. “People are literally shuffled out of the hospital with IV [intravenous drips] in their arms,” Abdul Kareem says.

The West’s indifference to all this – coupled with its occasional pious pronouncements and diplomatic dithering – has squandered any goodwill Washington might once have had among Syria’s beleaguered civilians. When Sergey Lavrov, Russia’s foreign minister, and John Kerry, the US secretary of state, agreed a ceasefire in September it lasted barely two days because they overlooked the fears of those trapped inside eastern Aleppo.

The deal had stated that no party would try to capture any new territory. That might seem reasonable enough but given that the ceasefire came into effect just days after Assad re-established the siege of Aleppo, those on the inside were being asked, in effect, to acquiesce to their own starvation.

Deprived of food and medication, no one trusted Assad to negotiate access in good faith, especially after he thwarted UN efforts to deliver aid. “People saw it as a conspiracy,” Abdul Kareem told me. Moreover, there were no significant groups inside eastern Aleppo that claimed to have accepted the terms of the ceasefire in the first place. Kerry had negotiated on their behalf without approval and without securing any humanitarian concessions.

“What planet are these people on?” Abdul Kareem asked. “[Do] they think people will turn on their protectors, for people who didn’t do them any good? They look to JFS and Ahrar [Ahrar al-Sham is one of the Islamist groups fighting in JAF]. Western intervention is pie in the sky.”

The rise of these reactionary rebels is a direct result of liberal elements not being strongly supported at any stage in the conflict. Left to fend for themselves, many have deserted their cause. Those who have persisted not only risk the constant threat of being killed by Russo-Syrian bombs, but are also at threat from jihadist elements operating in rebel areas. That much was clear when remnants of the secular opposition protested against the leader of JFS, Abu Mohammed al-Golani, in the southern Idlib town of Maarat al-Nouman earlier this year. Many of those who did were arrested by jihadists and intimidated into silence.

Whereas liberals are fragmented and frayed, the Islamist rebels continue to coalesce into an ever more coherent unit. The overwhelming might of Russian airpower has convinced them of the need to form a united front in order to pool their resources and co-ordinate their efforts. That is one of the reasons why a jihadist group called Jund al-Aqsa (“Soldiers of al-Aqsa”) announced early this month that it was disbanding and being absorbed into JFS.

Herein lies the real story of how Aleppo – and, indeed, Syria itself – has been delivered to the jihadists. A conspiracy of all the external parties has forged a menacing millenarian movement that is embedded in civil society and communities across the north. Whether Aleppo falls or not, the jihadists will endure.
