Inuit hunters in northern Greenland are treading carefully on increasingly thinning ice, while at the same time the key marine species they depend on -- seals, walrus, narwhals and polar bears -- are moving away from the areas in which they are traditionally hunted, as they in turn respond to changes in local ecosystems. In the high ranges of the Himalaya, Sherpa, Tamang, Kiranti, Dolpali and other indigenous groups are witnessing the melting of glaciers; the same is true in other mountain regions of the world such as the Peruvian Andes, where the indigenous Quechua report that they are worried when they look at the receding glaciers on their mountain peaks.

The threat posed by rising sea levels has been the centrepiece of climate change negotiations, the main issue emphasized by Small Island Developing States, also known as the SIDS. The poorer countries flanked by large bodies of water -- who have contributed the least to global warming, including rapid sea-level rise -- now find themselves at the precarious mercy of the historical polluters.

Despite the fact that Latin America and the Caribbean have the largest freshwater resources per capita, a third of the region's population is cut off from sustained access to drinking water. Up until a few years ago, freshwater problems had been generally characterized as a result of inequitable natural distribution, lack of adequate financing for water infrastructure, poor freshwater governance, or a combination of the three.

How does Africa intend to deal with climate change and how can it help shape a better future for itself in the face of the coming environmental catastrophe? As concerns grow, the continent will for the first time negotiate under one umbrella in Copenhagen.

Loss of habitat is the greatest threat to biological diversity, and 85 per cent of the species on the 2006 Norwegian red list are threatened by changes in habitat. Highly-specialized species appear to be the most vulnerable. The polar bear is one such species, and the extent and sustainability of sea ice is essential for its survival. The global population of polar bears consists of roughly 20,000-25,000 individuals spread between 19 sub-populations.

Every year in the past two decades, more than 200 million people, on average, have been affected by natural hazards. Disasters have caused a massive loss of life and negative long-term social, economic and environmental consequences. Vulnerable societies have been deeply affected, particularly in developing countries with less coping capacity.
