"And it's not through tables and graphs. Sometimes it is through art, through music, through poetry, and storytelling and that is increasingly something we have to think about - how we communicate in a more humanist way."
"Scientists have to stay engaged in the communication message. We will have to work at this. We will have to get the message out that this is a profound, deeply serious problem. It is urgent that we, as a science community, work together to advance the science and also to communicate it as effectively as we can so that we get the action that is so badly needed," she said.
Some scientists are already engaging with artists to get the message out, such as the London School of Economics' Grantham Institute on Climate Change, which held a "slam poetry" competition on the subject of climate change in March.
Naomi Hicks, of the Grantham Institute, said: "If we are to draw more of the public, particularly young people, into the debate on how best to manage the risks of climate change, we need to find better ways of communicating to them other than through turgid technical reports."
Meanwhile, Exeter University, the Met Office, the London College of Fashion and the Victoria & Albert Museum have collaborated on the "Climate Dress" - a project looking at how clothing can be used to communicate ideas about global warming, for example by using moving pictures of melting ice-caps and related data projected across the dress.
Dame Julia also called on the public to step up their action to publicise climate change, for example by recording the way it is affecting their immediate environment.
"Climate change is a massive opportunity for citizen science," she said. "For everybody who experiences the natural world, we can use all the social media tools that we have to document what we see happening to the world around us."
