1 in 5 land-based species are at risk of extinction due to climate change effects.
Greenpeace welcomes this authoritative report as significant confirmation that wind energy offers the clearest path to a low carbon future that minimises the dangers of climate change and allows us to meet Kyoto and UK carbon emission targets.
World Health Organisation figures indicate that 150,000 people die annually because of climate change impacts.

 On Bjorn Lomborg and extinction By E. O. Wilson Grist Magazine Arts and Minds 12 Dec 2001
Finally, consider that species extinction is increasingly enhanced by pollution, climate change, and the growing flood of invasive species-- hence the foregoing estimates of extinctions based on habitat reduction are, sadly, minimal and modest.
Although not enough species have been studied this way to produce regional or global extinction rate estimates, the high risk evident in the populations that have been examined is consistent with a high ongoing extinction rate.
Estimates for current species extinction rates range from 100 to 10,000 times that, but most hover close to 1,000 times prehuman levels (0.1 percent per year), with the rate projected to rise, and very likely sharply.

 Ostrich: Journal of African Ornithology - Vol. 75, No. 4 (2004)
The predicted changes to birds in Africa — the continent most at risk from climate change — have hardly been explored, yet birds and many other vertebrates face uncertain futures.
Climate change in southern Africa is expected to involve higher temperatures and lower rainfall, with less predictability and a greater frequency of severe storms, fires and El Niño events.
Global climate warming, now conclusively linked to anthropogenically-increased CO levels in the earth's atmosphere, has already had impacts on the earth's biodiversity and is predicted to threaten more than 1 million species with extinction by 2050.

 Species
Many species are being put at risk of extinction on a daily basis.
The change in temperature and climate is affecting species that dwell on land as well as the ocean.
The share of bird, mammal, and fish species that are now in danger of extinction is in double digits—11 percent of all bird species, 25 percent of mammals, and 34 percent of fish.

 BBC NEWS Science/Nature Climate risk 'to million species'
Climate change could drive a million of the world's species to extinction as soon as 2050, a scientific study says.
The study's lead author, Professor Chris Thomas, of the University of Leeds, UK, says: "If the projections can be extrapolated globally, and to other groups of land animals and plants, our analyses suggest that well over a million species could be threatened with extinction."
The authors say in the journal Nature a study of six world regions suggested a quarter of animals and plants living on the land could be forced into oblivion.

 Modeled climate and land-use change threatens plant species
Proteas--plants with large, colorful flowers that are important in the floral trade--are under threat from land-use change and climate change.
A study based on a multispecies modeling effort for over 300 proteas of the Cape Floristic Region of South Africa suggests that the protected range of proteas is expected to decrease by 36 to 60 percent by 2050 as a result of climate change.
The modeling work suggests that the risk of extinction for most protea species is likely to increase.

In the report, the most comprehensive analysis to date of potential species loss from man-made climate change, a team of 19 world scientists predicts that more than 1 million species could disappear, including an Australian tree lizard known as Boyd's forest dragon and a European magpie.
An international study in the journal Nature reports that more than one-third of all species in several regions of the world are at risk of extinction by 2050 if global warming isn't controlled.

 The Future and Geography
Geography is therefore not sitting in an old fashioned dusty corner of the schoolroom, fragmented and ready to be consigned to an academic dustbin but is a modern, unified, challenging discipline whose time has come and whose vision will be ignored at the risk of consigning the human race to the dustbin of extinction.
At the Environmental Education Association of Southern Africa conference held in Maseru, Lesotho in October 2001, a keynote speaker illustrated how interlinked the many environmental problems of Lesotho are, involving soils, climate change, farming systems and poverty.
By its very definition, Geography focuses on a spatial range between the size of the Earth (with its diameter of 12,000 km) down to the distance of a few centimeters, although for explanation, geographers will go outside this range to the subatomic or to the rest of the solar system and even beyond.

 Endangered Species: Cetaceans Introduction
Collisions with ships and entanglement in fishing gear threaten the North Atlantic right whale with extinction, while the critically endangered Western North Pacific gray whale is at serious risk because of intensive oil and gas development in its feeding grounds.
Alarm is also growing over other hazards including toxic contamination, the effects of climate change and habitat degradation.
The organization is also combating risks to whales by lobbying to bring whale hunting under the strict control of the International Whaling Commission, through field research, training and capacity building, conservation education, and by securing improved national and international action and agreements.
