Come back to us when you've got some LEDs

The lobbyists certainly earned their fees. The case for easing energy costs for UK manufacturers was made so effectively ahead of last month's budget that Chancellor George Osborne froze a tax he had introduced just two years before, seemingly forgot the tax was a replacement source of revenue to compensate for corporation tax cuts he had previously handed industry, and found yet more cash to round his energy cost compensation package up to £7bn. Add the windfall those industrial firms that have been hording EU emissions allowances will now enjoy as the carbon price continues its modest recovery and it has been a pretty fantastic few months for UK manufacturers - just so long as they are willing to turn a blind eye to the negative impact Osborne's reforms are likely to have on the decarbonisation efforts they are, for the most part, signed up to.

The reason manufacturers' lobbying proved so effective was that they had a genuinely compelling case to present. The UK may not be the only country in Europe with relatively high energy costs, but the upward trajectory of the carbon price floor would have led to escalating competitiveness issues over the course of the decade. Moreover, Germany provides a model for how compensation packages for manufacturers can address competitiveness concerns without necessarily undermining decarbonisation policies, even if it means more of the short term costs have to be shouldered by consumers.

However, the key question for Osborne should not have been 'how do I compensate manufacturers', but 'how do I tackle competitiveness concerns while continuing to accelerate decarbonisation?'

I've already argued the £7bn compensation package should have been accompanied by a comprehensive green industrial strategy backed by the kind of serious R&D spend required to deliver the next generation technologies we need to decarbonise heavy industry. But there is another step Osborne could and should still take that would actually help cut emissions, improve manufacturers' competitiveness, and drive investment. He should make the government's significant compensatory largesse dependent on manufacturers taking proactive steps to invest in energy efficiency and cut their emissions. If the government is providing a £7bn package on top of corporation tax cuts, and if there is now talk amongst manufacturers about the UK being so competitive re-shoring is a distinct possibility (which it is), then where is the quid pro quo?

There are actually some schemes, such as the Climate Change Agreements, that seek to incentivise emission reduction measures using the carrot of lower taxes, even if they are widely criticised for not demanding particularly ambitious decarbonisation measures of the companies that qualify for tax breaks. Meanwhile, Osborne actually took a modest additional step towards this approach in the Budget, making an exemption from the carbon price floor available to manufacturers operating ultra-efficient combined heat and power plants. But the fact is he could have been much more ambitious in linking compensation payments to carbon efficiency improvements.

The suggestion that financial support should be made dependent on action to enhance efficiency has been knocking around for some time, but it has been quietly opposed by much of the manufacturing lobby on two grounds - that it would be too bureaucratic to administer and it would be unnecessary on the grounds that high energy costs already provide manufacturers with every incentive they need to embrace efficiency.

However, do either of these objections really stack up?

For good or ill there is already a lot of bureaucracy (or progressive legislation, depending on your point of view) governing manufacturers' carbon emissions and energy use. It should not be beyond the wit of government minister to take the information obtained from the climate change levy, emissions reporting rules, or health and safety inspections and attach a clause to all compensation measures that allows the government to claw back some of the money at a later date if companies either fail to reduce their carbon intensity or fail to demonstrate that they have deployed energy efficiency measures.

The second objection, that manufacturers are already optimised from an energy efficiency perspective, should have more validity - and for some best in class firms it no doubt does. But is it really the case that every manufacturer benefitting from the new compensation package has LED lighting throughout their facility, electric cars on site, comprehensive insulation, and processes in place for checking compressed air systems are leak free? I'm guessing not.

If the Treasury was really committed to decarbonisation and manufacturers were really committed to optimising their long term competitiveness neither would have any problem with a sliding scale of compensation that rewards those who invest some of the money they receive in cutting their emissions.

The counter to this argument is that manufacturers can't afford it. Despite the often relatively rapid returns on investment offered by energy efficiency measures, many companies are unwilling or unable to find the capital they need to install LED lights or roll out the latest automated, optimised production line.

But this problem is just further evidence of a separate market and policy failure - namely the inability of the finance community to provide the targeted loans that would overcome the barriers to investment in energy efficiency measures. The banking sector had taken a well-deserved kicking over the last seven years, but to its litany of scandals must be added the utter failure to harness the power of responsible finance to drive mass investment in relatively low risk energy efficiency measures. Lord Adair Turner was right when he said much of banking had become "socially useless" - green finance should be the route to rediscovering the sector's social purpose.

There are a number of public and private energy efficiency financing options available for manufacturers, but a Treasury that was committed, in George Osborne's words, to becoming "a green ally, not a foe" would be looking to expand these offerings significantly, ideally by allowing the Green Investment Bank to borrow at ultra-low rates. It could then make energy cost compensation commensurate on energy efficiency improvements that would cost manufacturers nothing up front and would deliver net financial savings over time. Those who had already genuinely embraced green best practices should be allowed to pocket their compensation, and perhaps encouraged to start thinking about whether investment in renewable energy and decarbonisation R&D makes sense.

This corporate tribute to the Green Deal and pole-axed consequential improvements rule would cut manufacturers' energy costs, enhance their efficiency, and cut carbon emissions. Those manufacturers who continue to complain about energy costs should be politely but firmly told to come back when they have installed LEDs. Only those that have done precisely that should be rewarded with access to the Treasury's full compensation package.

IPCC Report: And now, for some good news

14 Apr 2014


It is always gratifying to have your assumptions confirmed, particularly when confirmation comes via one of the most comprehensive and in-depth academic exercises in history.

Yesterday's publication of the latest Intergovernmental Panel on Climate Change (IPCC) report on climate mitigation measures takes the microscope to virtually every assumption that supporters of the green economy hold dear - we can still keep climate change below 2ºC, clean technologies are plummeting in cost, decarbonisation can be delivered without damaging living standards, major technological transformations are needed across energy, industry, agriculture, transport and buildings, we risk stoking up a "carbon bubble" by continuing to invest in high carbon assets - and finds that not one of them is wanting. This satisfaction must be what climate sceptics feel like when they scour IPCC reports and find the one line in thousands that appears to agree with their flawed analysis, except in this case virtually every line agrees with new environmentalists' central assertion: a low carbon economy is feasible, affordable, and desirable.

What the latest IPCC report does so effectively is take the disgracefully under-reported clean tech revolution of the past decade and attempt to tell the world what has really happened.

A decade ago green business leaders and campaigners had to make their case using vague reassurances that a decarbonised global economy could be built through the mass deployment of clean technologies, which at that stage were often expensive and unreliable. But now, as the IPCC report demonstrates, we know that the cost of renewables has fallen drastically and that well-located wind and solar power can compete with fossil fuels, even when you pull the intellectually dishonest trick of not making fossil fuel energy pay for its climate impact. We know that zero emission vehicles are technically feasible and financially attractive. We know (as we always knew) that energy efficiency improvements to buildings deliver substantial savings over their lifetime. We know that making wider use of existing best practices and technologies can cut industrial emissions by a quarter. We know that nuclear and carbon capture and storage technologies can deliver utility scale energy capacity, even if some concerns remain about costs. We know gas can cut emissions by replacing coal, just as we also know that it is a short term fix at best and that a long term switch from coal to gas would be like a dieter switching from doughnuts to chocolate.

The IPCC captures these facts and confirms what we have also always known: the revolutionary improvements in clean technologies in recent years mean decarbonisation can be delivered at negligible cost to the economy.

In fact, the report even attempts to put a value on that negligible cost and comes up with 0.06 of a percentage point annually throughout the rest of the century. The cost is minute, barely a rounding error - but a penny lost in economic growth will be too much for some fossil fuel apologists who wrap themselves in the cloak of anti-poverty campaigning to defend their own financial self-interest. As such it is vital to note that the report's economic analysis does not include many of the benefits associated with decarbonisation. Add in the enormous, but difficult to quantify, benefits associated with clean technologies, such as improved air quality and energy security, and the ability of decarbonisation to deliver an economic boost alongside much-needed risk mitigation becomes obvious.

The report is basically the academic equivalent of that famous cartoon that lists the numerous upsides associated with a green economy and asks "What if climate change is a big hoax and we build a whole better world for nothing?" Except, as the preceding IPCC reports made plain, climate change is anything but a big hoax.

Critics of the green economy have argued the previous two IPCC reports' confirmation of spiralling carbon emissions and worsening climate risks proves the current approach to climate change is not working - an analysis that they then bizarrely use to argue for an end to any meaningful effort to tackle emissions. They are sadly right that climate policies have failed in their primary goal of cutting global emissions. But the IPCC's report and all the recent trends in clean tech deployment indicate that they have helped make renewables and other clean technologies technically and economically feasible. We need clean tech cost curves to continue to fall and we need to correct those areas of climate policy that remain flawed, but the potential is clearly there for green policies to still deliver on their ultimate goal of avoiding dangerous levels of climate change.

Inevitably, the report is not all (energy generating) sunshine and zephyrs. The shadow of the terrifying IPCC reports on climate science and adaptation loom large, particularly when the report notes that emissions have continued to climb rapidly over the past decade. The scale of a clean tech revolution that requires steep cuts in fossil fuel investments and drastic increases in clean energy spending is as daunting as ever.

Worst of all is the extent to which so much of the analysis does not reckon with the political, social, ideological, and financial inertia that characterises all economic interactions. Our continued failure to deliver proven cost-saving energy efficiency measures demonstrates that our economies are not set up to deliver perfectly rationale outcomes, even when certain clean technologies and business models are demonstrably better than their alternatives.

This inertia is evident in virtually every challenge the green economy faces, be it in the reports suggesting certain governments wanted sections of the IPCC report on the inefficiency of fossil fuel subsidies scratched out or the dismissive stance fossil fuel incumbents have struck towards the clean technologies that threaten their very existence (against this backdrop it was fascinating that the "carbon bubble" hypothesis and its warning that fossil fuel assets could very quickly become overvalued as the low carbon transition gathers pace, made it into the report). It is only through the continued development of ever more competitive clean technologies and the use of effective policies that recognise the huge risks inherent with the carbon intensive status quo that this inertia can be overcome.

However, while the challenge remains as daunting as ever, the report is shot through with compelling evidence that the world has already begun an historic transition towards a cleaner and more sustainable economy. This evidence is clear, not just throughout the latest IPCC report, but also throughout the expanding library of academic and investment research on the green economy. It takes a particular type of short-sighted, self-interested, small c conservatism to look at the latest IPCC report, look at the falling cost curves for renewable energy, look at the technical feasibility of nuclear and CCS, look at the projected increases in green investment that run to hundreds of billions of dollars, and not think that something exciting and significant is afoot.

It is utterly bemusing that certain newspapers can read the IPCC report and conclude that the big story is that there could be some role for gas as a "bridging fuel". It is akin to reporting on Neil Armstrong's moon walk by leading on the details of one of the rocket fuels that was considered - it's interesting, but it is hardly the main event. Equally, it is bemusing that certain multinationals and investors can continue to nonchalantly fund high carbon infrastructure without even acknowledging the technological transformations and shifting risk profiles that are obvious to anyone willing to look. It is not a new point, but they look ever more like typewriter manufacturers circa 1979.

At the very least governments and businesses looking at the implications from the IPCC report should be hedging their bets and reducing their exposure to fossil fuels while increasing their interest in clean technologies. However, entrepreneurs and true business leaders never settle for the very least, and as such they are already looking at the clean tech transition that is under way and working out how to seize the immense opportunities it offers.

The implications of the IPCC report for green business leaders are clear: a low carbon economy is feasible, affordable, and desirable, and that means it will also be investible, marketable, and profitable for those businesses willing to lead the clean tech revolution. After two reports of unremitting and justified climate doom and gloom, that is the good news.

The green home market is poised for take-off, clean tech firms need to crank up the heat

09 Apr 2014


There are few more effective ways to get someone to glaze over than to strike up a conversation about boilers. Although, in fairness, a discussion about insulation or double glazing may run it close. But the inherent challenge faced by those seeking to drive consumer demand for the various domestic energy efficiency measures now on offer need to be overcome, not least because some exciting developments are underway in the world of boilers.

Today has seen the long-awaited launch of the domestic element of the Renewable Heat Incentive (RHI) scheme, which will now offer households the opportunity to secure quarterly payments based on how much renewable heat they generate. There has been plenty of grumbling about the lengthy gestation for the scheme, while concerns remain about how effective the initiative will prove at ferreting out any rogue traders who seek to take advantage of increased demand for renewable heat systems. Others have highlighted the relatively high cost of carbon savings delivered by renewable heat systems compared to alternative technologies. But despite these reservations the scheme represents a significant boost to the green economy and could deliver a major breakthrough for the emerging green home market.

The merits of the scheme are two-fold. Firstly, as a world-first mechanism for driving adoption of renewable heat technologies it provides a boost to a much neglected clean tech area that will need to expand rapidly if the UK and other industrialised economies are to meet their long term carbon targets. Over 80 per cent of UK heating is provided by fossil fuels and in 2009 around 32 per cent of all greenhouse gas (GHG) emissions in the UK resulted from heat related activities. We already know how to decarbonise electricity supplies and the technologies required to do so are falling in price all the time. But there has been less progress in the development and adoption of renewable heat technologies, making the emergence of lower cost renewable heat systems a national priority.

The introduction of the RHI for both businesses and households promises to drive the market for heat pumps, biomass boilers, and solar thermal systems, fuelling technology innovation and driving down costs through economies of scale. The resulting emissions savings may be initially costly, but there is the potential for the UK to build a world-leading, potentially export-led, new clean tech market.

Secondly, the Domestic RHI forms the final piece in the puzzle, the final piece of lagging in the loft if you will, of the government's wider green homes strategy. Again, Ministers have faced plenty of justified criticism about the various delays and technical difficulties this strategy has endured through the controversial changes to the microgeneration feed-in tariff scheme, the cuts to the Energy Company Obligation (ECO) efficiency scheme, the watering down of green building standards, and the decidedly lukewarm reception for the Green Deal energy efficiency financing scheme. But the fact that each of these policies could and should be improved does not detract from the fact the UK now has a comprehensive and attractive package of measures to drive the transition towards greener and warmer homes.

The RHI means it makes financial sense for virtually everyone operating off-grid oil-fuelled heating to switch to renewable alternatives. The feed-in tariff and Domestic RHI means it makes financial sense for virtually everyone with south facing roofs or suitably located gardens to install solar PV, solar thermal, or micro-wind systems. The ECO and Green Deal means it makes sense for everyone to assess the energy efficiency of their home and undertake upgrades where appropriate. All of the policies means that it makes sense for anyone worried about rising energy costs or carbon emissions to see if their home is suitable for onsite power or heat generation.

There are valid questions about whether these schemes will disproportionately benefit the wealthy and middle class given the money and time needed to undertake such improvements. But the combination of grant funding and clever financing promises to deliver upgrades at no upfront cost across all social classes. Moreover, the scaling up of the green home market will benefit everyone in the long term as it cuts emissions, enhances energy security, and helps to bring down the costs of clean technologies to the point at which they come as standard in every home.

However, if the long-running travails of an insulation and energy efficiency sector that has always offered a product that makes financial sense are anything to go by, it is clear that being on the right side of return on investment calculations does not on its own create a market. The onus has to now be on the thousands of green businesses that provide Green Deal upgrades, heat pumps, solar panels, and biomass boilers to get out there and drive demand for the exciting technologies and services they offer. The introduction of the coalition government's last major green home policy means there is no longer any excuse.

To drive this market the clean tech sector needs to take a leaf out of the playbook of those industries that have created mass market demand for high value products - the auto sector, the IT and home entertainment industries, even the travel industry. They need to make their products attractive, effective, and, if possible, desirable. They need to target the early adopters and influencers who can create the initial market and force it into the mainstream (in short, and I know this may seem self-serving, they need to target the BusinessGreen audience). They need to use intelligent and proven advertising and marketing techniques to reach their target market. And then they need to deliver an exemplary product and service that quickly rides any cowboys out of the town and creates strong word of mouth demand.

Can this be done with energy efficient boilers and triple glazed windows? It is fair to say that even Don Draper would struggle to make them appear sexy. But as with any new product successful marketing is all about positioning. A modern, high tech, sustainable and warm home is better than a dated, functional, unsustainable and cold home. The studies showing how "contagious" solar panels spread through a neighbourhood prove there is huge pent up demand for clean technologies - clean technologies that polling reveals huge public support for. Even the dullest clean technology can be made exciting with the right messaging.

The UK's green businesses have an array of attractive, effective and desirable green products to offer, and the introduction of the RHI, feed-in tariff, and Green Deal means that in many cases they are now just as financially viable as they are technically viable. The green economy continues to face far more challenges and uncertainties than it should, and Ministers should be doing much more to drive the investment and business models we urgently need. But for the green home and office sector the policies are in place, the technologies are in place, the demand is there to be created - it is time to engage the consumer and start selling.

Cameron's proposed wind farm ban is costly, statist, and probably unworkable?

07 Apr 2014


Take a train journey pretty much anywhere in the UK and two things become quickly apparent: this is indeed a green and pleasant land, and significant parts of it are neither.

Around many of our cities, motorways, rail lines, out of town shopping centres, power stations, ports, and factories there is often found acre after acre of brownfield, semi-rural or semi-industrial land that is underutilised and underpopulated. I would never display the lack of manners characteristic of Tory peers and dismiss this land as "desolate", but even if beauty is always in the eye of the beholder you would be hard pressed to find many people willing to defend these areas' aesthetic appeal.

If you take a similar journey in many parts of Europe you will find these areas are used to great effect to generate clean energy through the deployment of small scale and often community-owned wind farms, but in the UK such installations remain about as rare as an MP's apology. This presents a huge opportunity to utilise semi-industrial and semi-rural areas to harness the UK's broadly excellent wind resources, generating clean energy, jobs, and investment in the process. However, it is an opportunity that a Prime Minister who is nominally committed to localism, tackling climate change, and cutting energy bills is about to dismiss out of hand.

According to various reports, David Cameron is highly likely to include a commitment to effectively "ban" new wind farm developments post-2020 in a desperate attempt to keep restive anti-wind backbenchers happy. It remains unclear how this ban will be imposed, but the most likely option seems to be a cap on the amount of power onshore wind farms can generate.

Perversely, this could be spun as something of a victory for the renewables sector, on the grounds the proposed "compromise" with those Tory MPs who want an immediate moratorium on onshore wind would allow the 8.2GW of wind farms currently in the planning system to continue to move forward. Meanwhile, green Tories appear to have secured a commitment from the Prime Minister for continued support for other forms of renewables, such as offshore wind and solar, post-2020 even if they cannot get him to agree to a decarbonisation target for the power sector. But if this is a victory it threatens to be a particularly hollow one, as the proposed ban will only serve to push up the cost of the clean energy transition while also undermining increasingly successful efforts by the industry to work with communities to tap into the consistently high levels of public support renewables projects receive.

In addition, it begs the question as to why a Conservative Prime Minister who rode into office on the promise of a greener government and increased localism is pursuing such a statist means of crushing a popular clean technology that typically commands over 60 per cent public support?

The answer is that the combination of improved wind turbine technology, staggering inconsistency at the heart of Conservative energy policy, and the Prime Minister's desperate attempts to appease the right of his own party have boxed him into a corner. He has evidently decided the UK should restrict the development of onshore wind farms to keep Conservative Party members happy, only to find that the tools for doing so are strangely limited.

Cameron could, of course, seek to cut subsidies for onshore wind farms in an attempt to undermine the financial case for onshore wind development. But here's the thing - cuts are already happening. Subsidy levels were reduced last year as the cost of wind energy fell and the government is now planning to move to a system of auctioning support contracts that will reduce subsidy levels further. In fact, if the experience in Brazil and other countries that have used auctioning is anything to go by, this approach could lead to increased wind farm investment as it only serves to highlight how well-located onshore wind farms are one of the most cost-effective forms of renewables - so much so that they can sometimes even undercut gas power on cost. You could, of course, deny onshore wind farms any form of subsidy, but that would deal a major blow to the government's entire electricity market reform programme, spark all kinds of legal repercussions, and torch what remains of the Prime Minister's green credentials.

Alternatively, Cameron could use the planning system to make it even harder to develop wind farms. But again, this is already being done. Local communities have numerous courses of action available when trying to block wind farm developments and UK planning rules are among the most robust in the world, rightly requiring planning committees to take account of everything from wildlife impact to aesthetic considerations. Any attempt to tighten planning laws still further for onshore wind farms alone would invite very awkward questions as to why the government is singling onshore wind farms out for special treatment at a time when it is planning to tear up subterranean property rights for householders in order to make life easier for fracking developers. Why should the concerns of someone worried about a turbine on the horizon be more important than someone worried about the solidity of their own home's foundations?

That leaves Cameron with some form of a moratorium as the only available tool should he want to bring an end to onshore wind farm development. But even here, it is not as simple as banning or capping new developments. You could seek to cap the amount of power that will be subsidised each year, but how do you set the cap when wind power output varies each year? And what do you do if falling onshore wind energy costs and rising fossil fuel costs make projects viable even if subsidy payments are capped three quarters of the way through the year? Alternatively you could just bluntly cap the amount of onshore wind power taken onto the grid each year. But why would a country that is trying to decarbonise turn off clean energy assets or block their future development? Does the cap only cover new projects or would it also apply to upgrades at existing sites as next generation wind turbines promise to deliver more power?

All these questions would need to be answered, and that is before you even get onto the wider point, raised by former Lib Dem Energy and Climate Change Secretary Chris Huhne this morning, around how the Tories can justify arbitrarily blocking the development of one of the cheapest forms of renewables, while simultaneously cutting support for energy efficiency and promising more support for much more costly offshore wind?

Of course, the Prime Minister is right on one thing: there will come a point when the public will say "enough is enough" when it comes to onshore wind farm development. There will come a point at which either all sites that are suitable from both a technical and aesthetic perspective have been developed or public support for onshore wind weakens so much that it becomes democratically unacceptable for development to continue (although, if coal, fracking, and nuclear is anything to go by, this public support threshold is remarkably low). But Cameron does not have a crystal ball - he cannot know when this point will come. If he did have such powers of prophecy then he could propose a ban for that point, at the same time as quietly reshuffling those ministers who will one day embarrass him with their innumerate inability to understand how expenses work.

But currently he cannot know whether the UK will need more or less onshore wind energy in the 2020s. The rollout of several more gigawatts of capacity over the next six years may make onshore wind farms as unpopular as coal power is now. But equally the success of community-owned projects, an oil price shock, or a nuclear disaster may make wind farms more popular than ever. Cameron understands the need to keep energy options open perfectly when he is praising the potential of fracking and carbon capture and storage, and yet for some reason the same rationale cannot be applied to onshore wind.

Instead he is apparently pursuing plans for a blanket ban that would be statist, costly, and very likely unworkable. But most of all he is trying to solve a problem that does not exist. We already have a policy framework that will drive down subsidies and impose strict planning requirements on developers. Why not just let it do its job? Let auctions ensure that only the best located and most efficient new projects are financially viable and let planning committees decide whether new projects are in the wider interests of the communities in which they are located. Let those projects that have secured sizable community support proceed in the same way that you let fracking, nuclear or new road projects proceed, and block those projects that are genuinely inappropriate, precisely as already happens.

Don't let a vocal minority completely derail a decarbonisation strategy that is in everyone's interests. And don't let backbench dinosaurs turn a Prime Minister who once promised to deliver a new era of environmentalism and localism into a hypocrite.

Climate adaptation lobby is reckless, dangerous, and (partly) right

01 Apr 2014


George Monbiot has a necessarily angry and hard-hitting column in today's Guardian analysing the staggeringly reckless response to yesterday's IPCC report from those who think it highlights humanity's ability to adapt to climate impacts.

As the Telegraph yesterday ran an editorial seeking to downplay the IPCC's projections and suggest that "instead of continued doom-mongering... thought needs to be given to how mankind might adapt to the climatic realities", Monbiot challenged the growing network of columnists who seem to think the global economy can and should simply adapt to climate change to identify which bit of the world they are prepared to lose.

"When our environment secretary, Owen Paterson, assures us that climate change 'is something we can adapt to over time' or Simon Jenkins, in the Guardian today, says that we should move towards 'thinking intelligently about how the world should adapt to what is already happening', what do they envisage?" he asks. "Cities relocated to higher ground? Roads and railways shifted inland? Rivers diverted? Arable land abandoned? Regions depopulated? Have they any clue about what this would cost? Of what the impacts would be on the people breezily being told to live with it?"

Monbiot is entirely right to ask these questions, not least because those who suggest the response to climate change should shift in its entirety from mitigation to adaptation so rarely want to answer them in any meaningful way. Although, coincidentally, one of the cheerleaders of the adaptation-only paradigm, economist and Telegraph contributor Andrew Lilico, did hint at a potential response to these questions yesterday afternoon. In the wake of the IPCC report's publication, I found myself in a Twitter exchange with Lilico in which I challenged his assertion that the report reinforced his argument that climate mitigation efforts should be killed off in favour of adaptation. "Any thoughts on how Tropics adapt to 4C world?" I asked. "I imagine Tropics adapt to 4C world by being wastelands with few folk living in them," Lilico responded. "Why's that not an option?"

And to think, those advocating an end to efforts to tackle greenhouse gas emissions get upset if you accuse them of callous recklessness.

However, while I am tempted to join Monbiot in "lashing out at the entire town" over this latest strand of climate scepticism (and while not all of those proposing an adapt-only approach to climate change are sceptical about climate science there are plenty who have a long track record of dismissing scientists warnings on this topic), I'd argue the increased focus on adaptation actually provides some cause for optimism for those of us who want to see much more ambitious action on climate change across the board.

Firstly, in calling for more focus on climate adaptation the Telegraph and its supporters have created a perverse consensus on climate change. If they want more investment in adaptation measures part of the response from green businesses and NGOs should be, "great, let's get on with it". Environmentalists should call what I suspect is a bluff from an adaptation lobby that in large part still refuses to accept the warnings presented by the IPCC and demand its support for the campaign to increase spending on flood defences and deliver improved supply chain resilience. Green campaigners should ask, "if you want adaptation why aren't you criticising inadequate adaptation budgets? If you think we can effectively adapt, where are your proposals for ensuring agricultural yields don't collapse? If you think the abandonment of certain areas is likely, how do you propose to maintain global security during such a transition?

As the IPCC report makes painfully plain, the adaptation-only argument is seriously flawed, but it could have the silver lining of making concerted action to enhance climate resilience more likely.

Secondly, the emergence of this adaptation argument highlights the extent to which the climate sceptic community has fragmented in recent years into those who cling to the idea that manmade climate change is not happening, those who think it is happening but won't be that bad, and those who think it is happening, it will probably be bad, but we can adapt to it. Significantly, the more influential commentators and politicians who are sympathetic to climate sceptic arguments tend to be found in the third of these cohorts, which in some ways is fortunate, because it is an argument that is so self-evidently weak that it is highly unlikely that it will gain serious traction with either policy makers or the public.

The "climate change isn't happening" or "it won't be that serious" hypotheses are collapsing under the weight of scientific certainty and, more importantly, real world evidence. It is hard to credibly maintain there isn't a problem when the evidence of both historic climate records and peoples' own eyes tells them that there is. But the adaptation-only argument similarly fails this "seeing is believing" test. It begs Monbiot's question: "If a small, rich, well-organised nation cannot protect its people from a winter of exceptional rainfall - which might have been caused by less than one degree of global warming - what hope do other nations have, when faced with four degrees or more?"

It also rests on a dodgy rationale that similarly invites public rejection. "Climate change is happening and is probably extremely serious" acknowledge advocates of a 100 per cent adaptation approach, "so let's do nothing about it besides building a few more sea walls". In accepting the scientific terms of the debate, often for the first time, those who say they want nothing more than adaptation acknowledge the gravity of the risks we face and then run straight into the scientific warnings that adaptation alone will not be enough. They also highlight the paucity of their ideas for dealing with related environmental challenges such as air pollution, ocean acidification, energy insecurity, and biodiversity loss - how do you get vulnerable species to fit into your adaptation strategy? Answer, you don't.

Those who want us to focus solely on adaptation invite incredulity from political leaders, business executives, and a public who increasingly accept the need and attractiveness of decarbonisation, as well as the economic growth on offer, and are doubtful that adaptation at the necessary scale is even possible, let alone desirable. The adaptation school of thought could prove hugely damaging to action on climate change if too widely adopted, but I'd argue it is unlikely to gain too much traction in a world where the two largest clean tech markets are the US and China, and many of the world's most powerful multinationals want more ambitious efforts to cut emissions.

Moreover, it also opens up an opportunity for dialogue between environmentalists and some of their more influential detractors that has not been there in the past. The one thing the likes of Lilico and Times columnist Tim Montgomerie can agree on with most green campaigners is that current efforts to sharply reduce global greenhouse gas emissions have not yet proved successful. We may disagree on what to do about this, but it is a much shorter journey from "let's focus on adaptation" to "let's also focus on new ways to cut emissions", than it is from "climate change isn't happening".

They won't admit it, but those who want climate change strategy to be boiled down to a focus on adaptation are edging towards the green consensus on the urgent need to tackle escalating climate risks. In challenging them to tell us precisely how they plan to deliver such adaptation we might just convince some of the cheerleaders for this reckless strategy to acknowledge that we probably should continue to pursue mitigation measures as well, just to be on the safe side.
