Can artists save the world?

Tracey Emin, Antony Gormley and others respond to climate change

A large, parasite-like form has appeared on the façade of 6 Burlington Gardens, London. It is the installation CO2morrow, by the artists Marcos Lutyens and Alessandro Marianantoni, for the exhibition "Earth: Art of a Changing World", which has just opened at the Royal Academy of Arts. The show presents the creative responses of 35 international artists to the pressing issue of climate change, just days before the big summit in Copenhagen is due to start.

CO2morrow's spectacular shape is the result of a cutting-edge technological innovation from California. It is made from recyclable carbon fibre and is based on a new carbon-scrubbing molecule. Commissioned by the National Trust for this exhibition, it shows, using a light display, fluctuating levels of CO2 in the atmosphere at specific national heritage sites.

"These molecules have the power to capture and retain carbon dioxide," Marianantoni tells me. "They are being produced in tonnes, with the main aim to be positioned on the top of power stations' chimneys. Scientists are currently working on a version for cars."

Like the whole RA exhibition, it raises fundamental questions about the responsibilities of artists in contemporary society and the relationship between art and technology.

"New technology is part of an artist's palette, as oil paints were during the Renaissance," explains Lutyens. "In a world where it is harnessed by corporations and by the military, it is important for artists to harness that same tool and use it for good."

The combination of science and art "helps to draw people's attention", continues the artist, "providing a wider view of what's going on. For example, the hi-tech sensors used in this installation to collect data extend our nervous system into the world around us. Without this kind of access, we would be blinder."

The artists exhibiting in this seminal show are, in the words of the co-curator David Buckland, "going to the edge before us". From Antony Gormley, with his striking crowd of clay figures staring at the viewer, to Mona Hatoum's threatening, cage-like steel globe; from the evocative island project by Antti Laitinen to the poignant journey to the Arctic reported by Sophie Calle, each issues his or her personal warning.

"There is no plan B for failure at Copenhagen, only plan A, and A stands for action," the UN's top climate official, Yvo de Boer, said recently. Six hundred digital clocks hanging on the wall of the RA, hauntingly ticking, help us to internalise the message.

How then to respond to these threats? Some artists have found their answer in a return to emotions. "My message is about love, nature and respect for nature," says Tracey Emin, commenting on her embroidered piece with figures of birds, flowers and insects. "For this work, I was inspired by a story that my father told me. At my father's wedding, my grandfather told his son's bride: 'Draw yourself a cross and in that cross put a volcano, a tidal wave, an avalanche and a hurricane. Now go and throw yourself at anyone.' "

Asked about their hopes for the coming climate conference, some artists are optimistic. But, as Emin remarks, "It is absolutely down to individual people to try to change something. After this show, I'll go home and I'll do stuff -- I'll turn my lights off and so on."

Leaving the Royal Academy, I hope that passers-by will raise their heads and wonder at that strange object nesting on the building's façade. Cycling, I feel I'm doing at least something to join the effort. And echoing in my ears is a line of a song from a video installation in the show: "What if we got it wrong?"

The campaign to keep Britain in Europe must be based on hope, not fear

Together we can show the world a generous, outward-facing Britain we can all be proud of.

Today the Liberal Democrats launched our national campaign to keep Britain in Europe. With the polls showing the outcome of this referendum is on a knife-edge, our party is determined to play a decisive role in this once in a generation fight. This will not be an easy campaign. But it is one we will relish as the UK's most outward-looking and internationalist party. Together in Europe the UK has delivered peace, created the world’s largest free trade area and given the British people the opportunity to live, work and travel freely across the continent. Now is the time to build on these achievements, not throw them all away.

Already we are hearing fear-mongering from both sides in this heated debate. On the one hand, Ukip and the feuding Leave campaigns have shamelessly seized on the events in Cologne at New Year to claim that British women will be at risk if the UK stays in Europe. On the other, David Cameron claims that the refugees he derides as a "bunch of migrants" in Calais will all descend on the other side of the Channel the minute Britain leaves the EU. The British public deserve better than this. Rather than constant mud-slinging and politicising of the world's biggest humanitarian crisis since the Second World War, we need a frank and honest debate about what is really at stake. Most importantly this should be a positive campaign, one that is fought on hope and not on fear. As we have a seen in Scotland, a referendum won through scare tactics alone risks winning the battle but losing the war.

The voice of business and civil society, from scientists and the police to environmental charities, have a crucial role to play in explaining how being in the EU benefits the British economy and enhances people's everyday lives. All those who believe in Britain's EU membership must not be afraid to speak out and make the positive case why being in Europe makes us more prosperous, stable and secure. Because at its heart this debate is not just about facts and figures, it is about what kind of country we want to be.

The Leave campaigns cannot agree what they believe in. Some want the UK to be an offshore, deregulated tax haven, others advocate a protectionist, mean-hearted country that shuts it doors to the world. As with so many populist movements, from Putin to Trump, they are defined not by what they are for but what they are against. Their failure to come up with a credible vision for our country's future is not patriotic, it is irresponsible.

This leaves the field open to put forward a united vision of Britain's place in Europe and the world. Liberal Democrats are clear what we believe in: an open, inclusive and tolerant nation that stands tall in the world and doesn't hide from it. We are not uncritical of the EU's institutions. Indeed as Liberals, we fiercely believe that power must be devolved to the lowest possible level, empowering communities and individuals wherever possible to make decisions for themselves. But we recognise that staying in Europe is the best way to find the solutions to the problems that don't stop at borders, rather than leaving them to our children and grandchildren. We believe Britain must put itself at the heart of our continent's future and shape a more effective and more accountable Europe, focused on responding to major global challenges we face.

Together in Europe we can build a strong and prosperous future, from pioneering research into life-saving new medicines to tackling climate change and fighting international crime. Together we can provide hope for the desperate and spread the peace we now take for granted to the rest of the world. And together we can show the world a generous, outward-facing Britain we can all be proud of. So if you agree then join the Liberal Democrat campaign today, to remain in together, and to stand up for the type of Britain you think we should be.
