Your Postcards from the Frontlines will be arriving at the UN in New York today, as this important week for climate change draws to a close. With each individual contribution consisting of a highly personal and entirely unique photograph and message, Postcards from the Frontlines has been a campaign unlike any other.

In the last ten days we have received new research on the amount of people displaced by extreme weather last year, seen hundreds of thousands of people across the world marching for action on climate change, and watched world leaders make pledges to reduce emissions. Your Postcards are arriving at a unique time in which climate change – and the need for urgent action – is on many peoples' minds.

We'd like to take this opportunity to thank you all for putting so much time, thought and care into creating your postcards in support of climate refugees.
