Carbon dioxide is the dominant greenhouse gas that causes global warming. The effects of global warming are uncertain, but they potentially include disruption of global weather patterns and ecosystems, flooding, severe storm, and droughts.
Carbon monoxide, when inhaled, combines with haemoglobin in our blood, impairing the flow of oxygen to our brain and other parts of the body. Carbon monoxide is colorless, odorless, and poisonous even to healthy people (at high levels). It can seriously affect people with heart disease, and can affect the central nervous system. Motor vehicles are the main source of carbon monoxide pollution in many countries.
Sulphur oxides contribute to respiratory illness, particularly in children and the elderly, and aggravate existing heart and lung disease

The Arctic Ice is Thawing
Father Christmas may have to move his"workshop"from the North Pole because global warming is
thawing the ice beneath his feet and his reindeers'feet as well.His"workshop"is in dire straits.The"plat-
form"for the"workshop"is melting,said Stefan Norris of the World Wildlife Fund environmental group's
Arctic Program.
An eight-nation report by 250 scientists published recently predicted the Arctic Ocean could be ice-free
in summer by 2100 because of a build-up of heat-trapping gases in the atmosphere,mainly from burning fossil
fuels in cars or factories.The North Pole is getting more and more uninhabitable to Father Christmas.
__________(46)Young people learn that Father Christmas'"workshop"produces millions of gifts delivered
by him on a flying,reindeer-drawn sleigh.Hollywood movies like"The Polar Express"tried to make viewers
believe that Father Christmas lives at the North Pole._______(47)
The"Fortress of Solitude"is near the North Pole that could be under threat in a warmer world. Alan Boldt,
spokesman of the Danish Ministry of Science,suggested ways to rescue Father Christmas._________(48)
Another alternative,he argued,woald be building some electrical facilities to ensure the ice stays on the North
Pole for him."This should be a subject for the United Nations,"he said."Danmark could build windmills to pro-
vide Father Christmas with power."Denmark says Father Christmas'real home is Greenland,which will help,
Denmark thinks,to strengthen its position in claiming the sovereignty over the Pole.__________(49)
"Doesn't he already speak Danish?"Boldt said frostily when asked if Father Christmas would be forced
to learn Danish if Denmark won international recognition of its claim to the Pole.Last month's Arctic report
said the region is warming twice as fast as the rest of the globe,partly because dark ground or water,once un-
covered,soaks up more heat than ice or snow.Finland has been most favored by Father Christmas and it has
about 500,000 tourists a year to visit its Christmas center in Rovaniemi in Lapland._________(50)
_________(50)
A.However,Nordic nations all reject it by claiming that their countries are his home.
B.Therefore the North Pole is the most attractive place in the world.
C.If Denmark's claim were accepted internationally,it would have the legal right to search for oil and gas at the North Pole.
D.One of them would be building a giant floating ice rink for the workshop if the Pole thaws.
E.Maybe Father Christmas has already moved to Rovaniemi.
F.He may have to move from the North Pole within our children's lifetimes.
