Hoesung Lee: ‘Climate change is a global problem, so individuals should encourage their governments to take action’ | |
Hoesung Lee, chair of the Intergovernmental Panel on Climate Change (IPCC), is up next, talking to Juliett. | |
What is your current assessment of how the world is dealing with climate change? | |
We are continuing to emit greenhouse gases and if unabated this will cause further warming and changes to the climate system. This increases the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. Substantial and sustained reduction in emissions are needed to limit climate change.” | |
What is the best action concerned citizens can take? | |
Individuals can do many things, depending on their local and personal circumstances. One example is improving energy efficiency. Ultimately [though] tackling climate change is a global problem, so individuals should encourage their governments to take action. | |
What is your message to President Donald Trump? | |
I’d like to congratulate Mr Trump on his forthcoming inauguration as President of the United States. We look forward to continuing to work with the new administration, and with American scientists and institutions, on improving our understanding of climate change and how to tackle its impacts and risks, as we have done for nearly 30 years, since the inception of the IPCC.” | |

Mark Campanale: Fossil fuel investors ‘will be left holding the baby whilst the world has moved on’ | |
Mark Campanale, founder of the Carbon Tracker Initiative thinktank and who conceived the idea that many fossil fuel reserves will be unburnable if the world beats climate change, talks to Damian now: | |
What is your current assessment of how the world is dealing with climate change? | |
There is no doubt now that we’re in the middle of a major technological revolution in the transportation and power sectors. Electrification of the transport fleet and the rise of cheap solar isn’t going to be reversed, actually it will accelerate. | |
The real question right now is whether technological leaps and cost reductions in renewables can accelerate adoption rates fast enough. The scale of the challenge is enormous – not helped by new investments in fossil fuels exceeding tens of trillions of dollars over the next few decades. | |
For that reason, we may not be seeing the reductions in fossil fuel power generation capacity that we need. Instead of investors looking at fossil fuel companies as ‘ex growth’ stocks, they are too many that take a ‘business as usual’ growth approach to their investment. Time will tell, but our expectation is that investors [anticipating ‘business as usual’ growth from fossil fuel stocks] will be left holding the baby whilst the world has moved on. The real risk is that the precious years we’ve got to make the difference we need to the future will have been tied up trying to defend the past. | |
What is your message to President Donald Trump? | |
If you’re interested in quality, high paying and skilled jobs for the American middle classes, then renewable energy has to absolutely be the place to look. It’s a sector with more employees now than in the US coal industry and with a long way to grow. | |
What is the best action concerned citizens can take? | |
Switch to a clean energy supplier like Good Energy, or maybe a community utility and project developer like Mongoose Energy. | |

May Boeve: ‘The climate movement is more important than ever’ | |
May Boeve, head of climate campaign group 350.org, is next up: | |
What is your current assessment of how the world is dealing with climate change? | |
I think we’ve entered into a new chapter in the climate fight. Renewables have become cheap and widespread enough to represent a real threat to the fossil fuel industry, so they’re beginning to fight back. If we can make it beyond the political barriers coming up worldwide and elect governments who take climate change seriously, we have all the technology we need to make rapid progress and succeed in keeping global warming as close to 1.5C as possible. But it’s going to be a real fight. The work of the climate movement is more important than ever. | |
What is the best action concerned citizens can take? | |
Organize. We can’t solve climate change alone. Get together with people and change your community, your country, and the world. | |
What is your message to President Donald Trump? | |
Quit. But if you have to stick around, realise that the clean energy economy is the greatest, biggest job creator in history. | |

Ed Davey: ‘To fight Isis and make America great again, invest in solar’ | |
Former climate secretary and Liberal Democrat MP now talks to Juliette Jowit | |
What is your current assessment of how the world is dealing with climate change? | |
The Paris agreement surpassed my expectations about what’s possible - although it’s still not enough, given where we are. We have had president Obama’s leadership, Xi Jinping’s (China’s) leadership, and president Modi’s (India’s) leadership. Then we had technological break-throughs, particularly solar.” | |
What is your message to President Donald Trump? | |
To fight Isis and make America great again, invest in solar. Where does Isis’ power come from? They are funded by oil and gas, particularly oil.” | |

It would be wrong to think that Donald Trump’s views on climate change reflect those of the American people. While the incoming president is dismissive of the overwhelming scientific consensus that global warming is real, serious and driven by human activity, the US population is not. A survey in November for the Yale program on Climate Change Communication found that 70% of Americans think climate change is real, and just over half, 55%, believe humans are mostly to blame. | |
The figures are encouraging. But they make clear that the US public, like those in other countries, lags far behind the scientific opinion. The fact is that many people still don’t accept that climate change is driven by human activities, and that it is serious enough to warrant action. | |
In the Guardian’s Science Weekly podcast today, we explore why climate change risks can be hard for us to take on board. Debika Shome at the TCC Group co-authored a report for Columbia University on the psychology of climate change communication. She explains how the perception that global warming is a problem for people who live far away and far in the future, combines with scientific jargon and the inherent uncertainty around climate predictions to make climate change messages an exceptionally tough sell. But here, another field of science can help. Understand human psychology better, and the messages can be made to hit home, she says. | |
During the US presidential re-election campaign in 2012, Matthew McGregor, now at Precision Strategies in New York, ran Barack Obama’s digital rapid response team. Matthew is not an expert on climate change, but he does know how to mobilise people to take action. We asked him how he would make people care more about climate change. Facts, he says, are not enough. | |
Also lending advice is Tima Bansal, professor of sustainability at Ivey Business School in Ontario. The climate change problem cannot be solved without help - and sometimes radical changes in behaviour - from businesses, large and small. But with little incentive to change their ways, what can we as consumers do to force corporations to act in the world’s best interests? As Bansal explains, it could be easier than you think. | |

Ben van Beurden: ‘We don’t have to sacrifice economic growth’ | |
Ben van Beurden, CEO of Royal Dutch Shell plc, now: | |
It’s good news for all of us that [the Paris climate agreement] came into force. The scenarios that we and others have done clearly show that a future of net-zero emissions is technically feasible near the end of the century. And not only can the world achieve it technically, but it also makes economic sense in a societal way. In other words, we don’t have to sacrifice economic growth. That’s the good part. | |
The remaining challenge is: can it be done commercially? Economically is about the way society can bear it, commercially is about how to make sure the main actors – consumers and companies – can, and will, do the right thing. And if society, through government, doesn’t ensure it makes commercial sense to move to a net-zero emissions energy system, nobody will make the next step. | |
The good thing is that the Paris agreement raised the bar for everyone. Everybody feels the obligation to act. So in that sense I’m actually very optimistic. | |
The nature of the challenge of climate change is that it will require unprecedented levels of co-operation between government, industry and society. What often tends to happen in our industry is that you have either isolated advocacy, or people have a very adversarial approach: I’m for, you’re against. In the end this doesn’t resolve anything. It just creates noise for policymakers. We have to move beyond that and start real collective planning for how we are going to achieve the kind of energy transition the world needs. | |

Craig Bennett: This is ‘decade zero’ | |
Craig Bennett, head of Friends of the Earth England, Wales and Northern Ireland, talks to Damian ... | |
What is your current assessment of how the world is dealing with climate change? | |
The climate impacts of global temperature rises of just 1C have already triggered melting ice-caps, unleashed killer storms and droughts, bleached the world’s coral reefs, choked our cities with pollution and displaced people from their homes. The case for urgent action is now universally accepted by governments, scientists, business and ordinary citizens around the world. | |
Whilst trillions of dollars are being invested in the renewable energy sector and building a low carbon economy, this is still too little and too slow. This is ‘decade zero’: The decisions we make now on meeting our energy needs, producing our food and protecting our forests will determine if we can keep temperature rises well below 2C and prevent catastrophic climate change. We’re sitting in the last chance saloon but governments still seem unable to break their addiction to dirty energy – unless people power can make them. | |
What is your message to President Donald Trump? | |
Renewable energy and the low carbon economy is the world’s greatest job creator. Be smart, and lead from the front. Clean energy, owned by American citizens, acting in the interests of American citizens will not only make ‘America Great Again’, it will save lives and protect your nation too. | |
What is the best action concerned citizens can take? | |
Be part of the movement to ‘keep fossil fuels in the ground’. It’s as simple as that. Divest your money from banks that fund it, switch energy suppliers to green energy, support communities saying no to fracking, demand our politicians act now before it’s too late. And join an environmental organisation like Friends of the Earth. | |

Professor Dame Julia King: ‘Trump needs to build an economy for 2050, not 1950’ | |
Prof Dame Julia King, an eminent engineer and one of the UK government’s official advisers at the Committee on Climate Change is next up, talking to Damian Carrington. | |
What is your current assessment of how the world is dealing with climate change? | |
To have a good chance of keeping global temperature rise to below 2C the world will need to reverse the rise in greenhouse gas emissions and reduce carbon dioxide emissions to zero within the next 50 years or so. This involves switching to clean forms of electricity, transport, cooling and heating, and finding ways to avoid – or mop up – emissions from industry, agriculture, shipping and air travel. We are not currently on track to achieve this, but global momentum is building quickly. What is encouraging is that many companies, cities and citizens are now taking a leading role, alongside pledges and action from governments around the world. | |
What is your message to President Donald Trump? | |
If President Trump wants to deliver greater job security for Americans, he should focus on clean and sustainable industries where the US has a competitive advantage. Those are the sectors that are set to prosper. He needs to build an economy for 2050, not one for 1950! | |
What is the best action concerned citizens can take? | |
The Committee on Climate Change recently looked at how to reduce UK emissions over the next 15 years. We found that some of the best things people can do to reduce their household-level carbon footprint are: | |
Save money, by making your home energy efficient, and making choices on food and travel that lower costs and emissions. | |
Take advantage of new technologies – if you drive, switch to a fully electric vehicle and look at a smart home energy system. | |
Make your voice heard, by, for example, continuing to talk to your local politician and others to urge them to act, find out what companies your pension fund invests in and write to the trustees to encourage them to switch to ‘low carbon’ investments. | |

Michael Liebrich: ‘Wind and solar now the cheapest new power sources in much of the world’ | |
Now it’s Michael Liebrich, founder of analyst firm Bloomberg New Energy Finance and who has advised the UN and World Economic Forum on energy, speaking to Damian Carrington. | |
What is your current assessment of how the world is dealing with climate change? | |
The past decade gives us enormous cause for optimism. Relentless growth in global CO2 emissions has been brought to a halt much earlier than anyone thought possible. Wind and solar power have become the cheapest new power sources in much of the world; natural gas is outcompeting carbon-intensive coal; LEDs and other energy efficiency solutions are being installed at scale; and electric vehicles are starting to fly out of showrooms. | |
But it’s not enough to stabilise emissions: to stay within a 2C carbon budget we have to see emissions cut dramatically and quickly, which remains a staggering challenge. The Paris agreement set out ambitious long-term aspirations, but its near-term commitments don’t add up to much. In particular, if Asian countries build all the coal-fired power stations currently in their plans, then kiss goodbye to the 2C warming target. | |
What is your message to President Donald Trump? | |
If I had one minute with president elect Trump my message would be that the best way to ‘Make America Great Again’ is by owning the clean energy, transportation and infrastructure technologies of the future. Not only will this create countless well-paid, fulfilling jobs for Americans, but will also lock in the US’s geopolitical leadership for another generation. | |
What is the best action concerned citizens can take? | |
Focus on a few big things. If you are renovating, insist on lots of insulation, good windows, a good boiler and efficient appliances. You can cut your fuel bills by 75% – I know because I’ve done it. If you live in a city, get rid of your car: join a car club, walk or cycle more, use cabs and public transport. Again, I know because I haven’t owned a car in London for 22 years. And don’t fly short-haul, use trains – you’ll get there quicker too. | |

John Schellnhuber: ‘We are now at a watershed in history’ | |
Prof John Schellnhuber, at the Potsdam Institute for Climate Impact Research in Germany, and who has advised Angela Merkel, the Pope and the EU, now speaks to Damian Carrington. | |
We are now at a watershed in history I think, because the traditional industrialised countries – US, UK, parts of Europe, Australia – are now more or less giving up being pioneers for climate action and it is emerging economies [like China and India] that are doing the bold steps. The world is upside down really. The old developed world has more or less lost faith in saving the planet and it is the new economies who seem to take the lead. This is the hope we have. | |
Politicians can’t do it on their own. The political process is so slow and dysfunctional almost everywhere. There are two factors that can accelerate our transition to sustainability. One is clearly technological progress, which is often much faster than anybody expects. The other is civil society, you have to put pressure on your politicians. You have to raise the moral bar much higher. You have ask them ‘do we want to save this planet for our descendents or not? | |
On the actions concerned individuals can take, Schellnhuber said three things stick out: | |
Try to avoid using airplanes. Whenever you do a carbon balance sheet, you see flying is just the worst thing you can do regarding your carbon footprint and often it is more convenient to take a train these days. Second is to reduce your meat consumption, if you eat any, and that is also good for your health. | |
The third one is follow the money: the fossil fuel divestment movement. Tell your bank manager you would like your money be invested into renewables instead of coal, oil and gas industry. At least become a pain in the neck. What companies fear like hell is loss of reputation, as that can break even the big companies’ necks. | |

Nicholas Stern: ‘Destruction of the environment would reverse economic growth’ | |
Leading climate change economist Lord Nicholas Stern, at the London School of Economics, has also spoken to Damian Carrington for this blog. | |
Stern said global action on climate change has made substantial progress, with the Paris agreement and the UN’s sustainable development goals creating a global agenda for the first time since the end of the second world war. | |
It was agreed by everybody and applies to everybody. That is extremely important and quite extraordinary when you think how difficult it is to put together a global agenda with 196 countries. | |
But he said it was openly acknowledged that the Paris deal leaves a big gap between the current plans and what is needed to avoid 2C of global warming - the danger limit agreed by the world’s nations. | |
The next very big question is how do we ramp up those ambitions. China, the biggest emitter, is ahead of the game. It said it would peak [its carbon emissions] by 2030, but my guess is it will peak not very long after 2020. That is the key example. I have been working in China for 30 years and the change over the last six to seven is quite remarkable. | |
India is starting to get much more committed too. So if you look at the two countries with the biggest populations, you do see changes. But the US and Europe will matter greatly to this. It is very important Europe raises its game. | |
Stern said Donald Trump needs to back the green economy to take advantage of the growing global demand for clean energy, which is being driven by the worldwide commitment to tackling global warming. | |
If you want to make America great again, building modern, clean and smart infrastructure makes tremendous commercial and national sense, In the longer term, the low carbon growth story is the only growth story on offer. There is no long-term, high-carbon growth story, because destruction of the environment would reverse growth. | |
Stern said concerned individuals should put pressure on governments and businesses: | |
Demand explicitly and directly strong action from the politicians, particularly in cities where we know action can be extremely rapid. Do your shopping at firms that are responsible. It does need political, business and civil society push. The reason is that the urgency and scale is not sufficiently understood. We will double the world economy in the next 20 years or so. If we build this new world economy anything like the old one, then we are not going to get down to the [emissions] we have to be. There has to be radical change. | |

There are very positive actions and signals from all areas of society post-Paris [climate agreement] including from governments and cities to business, investors and citizens. But the reality is also that greenhouse gas emissions in the atmosphere continue to rise and thus national and international ambition needs to rise even more. The world needs to peak global emissions urgently and trigger a steady but significant de-carbonisation of the global economy so that year on year and decade on decade the total achievement is in line with the science. We are on the way towards a better, climate-secure world, but it will be a long journey and only a sense of urgency will get us to the ‘well below 2C target’. | There are very positive actions and signals from all areas of society post-Paris [climate agreement] including from governments and cities to business, investors and citizens.

Low. Although you are right that those ice caps are very vulnerable to global warming, it takes a long time to melt such big chunks of ice. But in coming centuries, the risk is very real. The last time the Earth had CO2 levels as high as this, sea level was many metres above what it is today. That would wipe out many of the world’s biggest cities. | Low.
