Model and photographer Helena Christensen returned to her Peruvian roots and her mother's native country to document the dramatic effects that climate change is having on people today.

Following the trip, Helena said:

"The impacts of the climate change are extremely severe in the areas we visited. The farmers we met and talked to are already living very hard lives, and are now being forced to adapt to salvage the effects of the rapidly changing climate.

"One of the women I spoke to, Elizabeth Ayma, told me that because rainfalls are less frequent now and impossible to predict due to the climate changes, this is having a huge effect on crop production. As a result, her family has less food to eat and less produce to sell, resulting in her not being able to afford her children's school fees. The lack of nutritional vegetables also affects her family's health."

Helena went to Peru with Oxfam on this journey and her photographs will be exhibited in New York, Washington, London and at the UN Conference on Climate Change in Copenhagen in December. A short film of the expedition, captured by award-winning Director Richard Bullock, will also be shown.

Helena said:

"We are at a critical tipping point. We need to put pressure on our governments in order for them to take the necessary, radical steps that are needed to lower CO2 emissions. There's no time left, it is absolutely imperative to act now. Hopefully the only benefit of this UN conference won't be just a boost to Danish tourism."

Frank Boeren, Oxfam International's co-ordinator in Peru said,

"Climate change in Peru is already devastating and we welcome Helena's commitment to show this to the rest of the world. Peru is on the frontline of climate change, along with other developing countries, which have played little part in causing the problem.

"It is crucial that rich leaders do the right thing at Copenhagen so that we can begin to stop run away climate change and protect vulnerable people around the world".
