As climate change negotiations kicked off in Dubai, countries reached a historic agreement for a new fund to help developing countries which bear the brunt of climate impacts.

More than $400 million was announced, with the largest pledges coming from Germany and the United Arab Emirates, to kick off the "loss and damage" fund. They are the first pledges since the fund was created at climate negotiations last year.
