Countries such as El Salvador hit hardest by climate

At the Doha talks, environment organization Germanwatch has presented its climate risk index, showing which countries are most affected by climate change: of course, it's the poorest that are worst hit.

"It rained ten days in a row on one occasion," Antonia Canas Calderon recalls, "and the amount of rain in 2011 was 41 percent higher than the average for the last four decades." As a result of the increase, El Salvador lost over one third of its GDP, says Canas who's at the Doha conference as part of El Salvador's delegation to the climate talks.

It's that rainfall that has put El Salvador fourth in the ranking of the climate risk index.
