Polar bears and seals are a good example of animals that will be affected by climate change, they will have to find new land for hunting and living, if the ice in the Arctic melts, but the fact is more real that these species could become extinct. Climate changes will affect everyone, ...
Reducing the Effects of Climate Change Mark Rowe reports on the increasingly ambitious geo-engineering projects being explored by scientists A Such is our dependence on fossil fuels, and such is the…
Faster Ice melting:Anthropogenic climate change will have effects on global sea ice. The IPCC Special Report on the Oceans and Cryosphere has shown how these trends are likely going to continue into the future. The impact of climate change on the Arctic is more linear than in the...
The destabilizing effects of climate change will worsen risks to national security, especially as countries around the world continue haggling over who bears responsibility for reining in emissions, according to a seminal new assessment released Thursday by the Office of the Director of National Intelli...

Polar bears are not the only animals to change their migratory patterns. Walrus, whales, and seals are changing their migrating habits also. This is making it increasing difficult for the natives of the land to hunt and find suitable food. The melting of the ice caps is harming the natives...
Climate change and ice breeding pinnipeds Potential effects of arctic warming on marine mammals have been discussed in terms of decreased areal extent of the ice, but the most immediate effects may result from more subtle changes in the distribution of ice and snow that ... BP Kelly - Springe...
