Climate change threatens human rights of millions: U.N.

By Laura MacInnis

GENEVA (Reuters) - Climate change threatens the human rights of millions of people who are at risk of losing access to housing, food and clean water unless governments intervene early to counter its effects, experts said on Tuesday.

At a conference on climate change and migration, United Nations officials said rising sea levels and intense storms, droughts and floods could force scores of people from their homes and off their lands -- some permanently.

"Global warming and extreme weather conditions may have calamitous consequences for the human rights of millions of people," said Kyung-wha Kang, the U.N. deputy high commissioner for human rights.

"Ultimately climate change may affect the very right to life of various individuals," she said, pointing to threats of hunger, malnutrition, exposure to disease and lost livelihoods, particularly in poor rural areas dependent on fertile soil.

Kang, a South Korean, said countries had an obligation "to prevent and address some of the direst consequences that climate change may reap on human rights."

This may include providing safe housing, ensuring good sanitation and water-drinking supplies, and making sure citizens have access to information and legal redress, and take part in decision-making, she said.

Environmental disasters and natural resource scarcity have long been seen as contributors to displacement, for instance in Sudan's Darfur region where 2.5 million people have been driven from their homes by conflict rooted in part in access to water.

But the United Nations has not yet expressly tackled climate change as a human right, for instance by enshrining the right to protection from its effects in an international convention.
