Former President Mary Robinson has said climate change is a serious threat from developed nations to the human rights of people in developing countries.

She said that the world needed to move from the mindset of the developed world - which is concerned with issues such as competitiveness - to one from the poorest counties, which is more people centred and considers the needs of communities in the least-developed countries who are suffering most but have contributed least to the problem.

Speaking in Dublin today, she called for a legally binding international agreement: to compel richer nations to support the poorest counties and help them to adapt to climate change.

She said such an accord should succeed the Kyoto Protocol at the end of next year.

Mrs Robinson said that the 50 least-developed nations of the world are responsible for less than 1% of greenhouse gas emissions.

Yet, she said, they are suffering through disruption to weather patterns, changing seasonality and impacts on subsistence agriculture.

She said nothing brought this home to her more than the recent visit she made to the horn of Africa.

But, she said that the situation in Somalia has not had the degree of response that they would have wished.

She said a recognition of the threat from climate change to such basic human rights - such as the right to water, food, and health that led her to found the Mary Robinson Foundation - Climate Justice.
