Human rights of those living in undeveloped countries have contributed least to the problem of climate change, but they are suffering the most due to the fast-increasing problem, former president Mary Robinson has said.

Speaking at the Institute of International & European Affairs in Dublin, Mrs. Robinson said that climate change amounted to a serious threat from developed countries to people living in undeveloped countries.

Explaining the concept of climate justice, she said richer nations should be forced to financially and technically support the underworld countries in adapting to climate change.

Speaking on the topic, she added, "Let us bear in mind that the 50 least developed nations of the world account for less than 1 per cent of greenhouse gas emissions that cause climate change. They are suffering through disruption to weather patterns, changing seasonality and impacts on subsistence agriculture."

She also called for an international agreement to succeed the Kyoto Protocol at the end of 2012, which would legally force developed countries to help poorest countries.

Mrs. Robinson added that it was the threat from climate change to basic human rights, such as the right to water, food, and health, which prompted her to found the Mary Robinson Foundation- Climate Justice.
