What could be the effects of climate change for life on earth?

It is well known that climate change is endangering the polar bear, but according to the International Union for the Conservation of Nature (IUCN) there are as many as 10,000 species likely to become extinct as a result of climate change in the next 50 years alone. The bleaching of coral reefs and death of plankton caused by rising sea temperatures will seriously affect marine biodiversity and the ocean food chain (and dependent bird species). Amongst many other adverse effects on ecosystems, global warming is causing infestations of tree-killing beetles and playing havoc with the migratory habits of animals and birds.
