| The effects are already apparent. Many species in temperate areas are shifting their distributions, with cold-adapted forms retreating toward the poles, to be replaced by species from warmer climates. Similar shifts in altitude are occurring among mountain species. Arctic species, like polar bears, that are dependent on the ice, are in great difficulty. Coral reefs around the world have bleached and died from unusually high water temperatures. The number of the most intense cyclones (hurricanes) has increased in all oceans over the last 30 years, driven by greater heat energy in tropical ocean waters (IPCC 2005, 01-10).
One effect of global warming is a rise in sea level, due to both, [sic] the thermal expansion of water and the melting of glaciers and ice caps. Sea level rise will flood low-lying areas and islands, including many port cities, creating millions of refugees. The projections for Bangladesh show, a 1.5 meter rise will displace 17 million people from 16 percent of the country's area. If the Greenland ice sheet is destabilised - which now appears to be likely - it will raise the sea level by more than 6 meters. Already some low-lying islands and coastal areas are being abandoned (IPCC 2001). Climate Change on the predicted scale will profoundly affect the environment and human activity in many fundamental ways. Food insecurity will increase and many regions will experience water shortages as rainfall patterns shift and mountain glaciers disappear. Rich countries can probably afford to adapt their agriculture with improved crop varieties and new technology, but all scenarios show a severe decline in food production in developing countries. The greatest human impact of Climate Change will be on the poor, who are especially vulnerable to the predicted increase in extreme weather events such as floods, cyclones and droughts - the latter particularly pertaining [to Africa.] IPCC (Intergovernmental Panel On Climate Change) (2001).

Climate change on the predicted scale will profoundly affect the environment and human activity in many fundamental ways. Food insecurity will increase and many regions will experience water shortages as rainfall patterns shift and mountain glaciers disappear. Rich countries can probably afford to adapt their agriculture with changed crop varieties and new technology, but all scenarios show a severe decline in food production in developing countries. The greatest human impact of climate change will be on the poor, who are especially vulnerable to the predicted increase in extreme weather events such as floods, cyclones, and droughts—the latter particularly pertaining to Africa.

The sources given are not the sources for the almost verbatim use of Dahl 2005. Other than formatting changes and the insertion of two spurious references, the text is identical, except that changed crop varieties becomes improved crop varieties. The text and numbers attributed to IPCC 2001 are not in that document. |
