Four children from the Jubilee Primary School in Stoke Newington visited Downing Street this week to personally deliver their stunning artworks depicting the causes of climate change in London and the impacts felt in Bangladesh.

A petition of over 2,000 names was also handed to the Prime Minister, ahead of the vital UN climate change talks in Copenhagen this month by eight-year-olds Finlay Johnson-Richards and Ruby Bottolph; nine-year-old Angel Newsome and 11-year-old Rezwana Quyyum.

Artist Jamie Hewlett had visited Char Atra in Bangladesh with Oxfam earlier this year, and created nine watercolours based on his experience there. The exhibition of his work was held at the Truman Brewery of Dray Walk Gallery, Shoreditch which the children has visited and drew inspiration from.

Jubilee Primary teacher, Melissa Davies-Oliveck, said: "It was great for the children to come along here to Downing Street today. They have gone from learning about climate change at school, to visiting the Jamie Hewlett exhibition, to actually handing in their artwork to Number 10.

“It's so important that the children have seen that they can take action and have power to make their voices heard on the need to tackle climate change.”

At Copenhagen, leaders of the richest countries must take a lead in negotiating a deal that prevents dangerous temperature rises and protects the world’s poor, who are already feeling the affects of man-made climate change despite being least responsible.

Oxfam is calling for carbon cuts of 40 per cent by 2020 from rich countries, and a total fund - additional to existing aid budgets - of $200 billion per year to help poor countries mitigate and adapt.

According to science reports presented at an earlier summit, 26 million people have already been displaced due to climate change and 200 million people may be on the move each year by 2050 because of hunger, environmental degradation and loss of land.
