Global warming: scientists reveal timetable
By Michael McCarthy, Environment Correspondent
03 February 2005
 A detailed timetable of the destruction and distress that global 
warming is likely to cause the world was unveiled yesterday.
It pulls together for the first time the projected impacts on ecosystems 
and wildlife, food production, water resources and economies across the 
earth, for given rises in global temperature expected during the next 
hundred years.
The resultant picture gives the most wide-ranging impression yet of the 
bewildering array of destructive effects that climate change is expected 
to exert on different regions, from the mountains of Europe and the 
rainforests of the Amazon to the coral reefs of the tropics.
Produced through a synthesis of a wide range of recent academic studies, 
it was presented as a paper yesterday to the international conference on 
climate change being held at the UK Met Office headquarters in Exeter by 
the author Bill Hare, of the Potsdam Institute for Climate Impact 
Research, Germany's leading global warming research institute.
The conference has been called personally by Tony Blair as part of 
Britain's attempts to move the climate change issue up the agenda during 
the current UK presidency of the G8 group of rich nations, and the 
European Union. It has already heard disturbing warnings from the latest 
climate research, including the revelation on Tuesday from the British 
Antarctic Survey that the massive West Antarctic ice sheet might be 
disintegrating - an event which, if it happened completely, would raise 
sea levels around the world by 16ft (4.9 metres).
Dr Hare's timetable shows the impacts of climate change multiplying 
rapidly as average global temperature goes up, towards 1C above levels 
before the industrial revolution, then to 2C, and then 3C.
As present world temperatures are already 0.7C above the pre-industrial 
level, the process is well under way. In the near future - the next 25 
years - as the temperature climbs to the 1C mark, some specialised 
ecosystems will start to feel stress, such as the tropical highland 
forests of Queensland, which contain a large number of Australia's 
endemic plant species, and the succulent karoo plant region of South 
Africa. In some developing countries, food production will start to 
decline, water shortage problems will worsen and there will be net 
losses in GDP.
It is when the temperature moves up to 2C above the pre-industrial 
level, expected in the middle of this century - within the lifetime of 
many people alive today - that serious effects start to come thick and 
fast, studies suggest.
Substantial losses of Arctic sea ice will threaten species such as polar 
bears and walruses, while in tropical regions "bleaching" of coral reefs 
will become more frequent - when the animals that live in the coral are 
forced out by high temperatures and the reef may die. Mediterranean 
regions will be hit by more forest fires and insect pests, while in 
regions of the US such as the Rockies, rivers may become too warm for 
trout and salmon.
In South Africa, the Fynbos, the world's most remarkable floral kingdom 
which has more than 8,000 endemic wild flowers, will start to lose its 
species, as will alpine areas from Europe to Australia; the broad-leaved 
forests of China will start to die. The numbers at risk from hunger will 
increase and another billion and a half people will face water 
shortages, and GDP losses in some developing countries will become 
significant.
But when the temperature moves up to the 3C level, expected in the early 
part of the second half of the century, these effects will become 
critical. There is likely to be irreversible damage to the Amazon 
rainforest, leading to its collapse, and the complete destruction of 
coral reefs is likely to be widespread.
The alpine flora of Europe, Australia and New Zealand will probably 
disappear completely, with increasing numbers of extinctions of other 
plant species. There will be severe losses of China's broadleaved 
forests, and in South Africa the flora of the Succulent Karoo will be 
destroyed, and the flora of the Fynbos will be hugely damaged.
There will be a rapid increase in populations exposed to hunger, with up 
to 5.5 billion people living in regions with large losses in crop 
production, while another 3 billion people will have increased risk of 
water shortages.
Above the 3C raised level, which may be after 2070, the effects will be 
catastrophic: the Arctic sea ice will disappear, and species such as 
polar bears and walruses may disappear with it, while the main prey 
species of Arctic carnivores, such as wolves, Arctic foxes and the 
collared lemming, will have gone from 80 per cent of their range, 
critically endangering predators.
In human terms there is likely to be catastrophe too, with water stress 
becoming even worse, and whole regions becoming unsuitable for producing 
food, while there will be substantial impacts on global GDP.

In Rima, addirittura?
Be', prepara l'Ashram, che una volta ti passo a trovare.
Pero' mi raccomando, non farlo in riva al mare...
Guarda dove i wallabi si sentono sicuri - non i wannabe...
