PartIV More about the topic: is Earth Overheating?
Evidence shows that over the past 160 000 years there has been a close correlation between global average temperature and the amount of carbon dioxide in the atmosphere.
In 1800,before the Industrial Revolution began to take full effect, the carbon dioxide level was about 280ppm,By the 1890's the carbon dioxide level had risen to perhaps290ppm.Today,according to analyses of air samples,the level is more than 350ppm. 25 per cent higher than the 1800 level.
At the same time, Scientist have noted that the global average temperature is steadily rising.Since the 1980's ,most summers have been unusually hot,in fact,the six warmest year since 1901 have occurred in the past two decades,and 1988 saw the century's highest global average temperature.the 1988 heat wave focused public attention on a possibility that had worried scientists for some time---the possibility of a disastrous rise in Earth's temperature.
Scientists tell us that it is the burning of coal, oil,and other fuels that has increased the amount of carbon dioxide in the atmosphere,Factories account for 29 per cent of the carbon dioxide added by the burning of fuels;electric power plants,28 per cent; motor vehicles,27 per cent; and heating equipment for homes and business,16 per cent.
As Stephen Schneider,a climatologist at the National Center for Atmospheric Research puts it, "it is often said that we do not so much inherit the world from our forebears,but rather we borrow it from your children .it is increasingly urgent that we act to prevent our debt from growing out of control.

Part V Memory test:Weather Forecast
A:Announcer:....and now for the weather forecast.Tomorrow will be another cold day generally in all parts of the country,with maximum temperatures of five degrees above zero.Around London and the southeast of England it will be a dry day,with some sunshine on the southeast coast in the afternoon.In the southeast the morning will be sunny,but during the afternoon it will be cloudy,with some rain on the southeast coast. the north of England and Scotland will be very cold and windy all day.

B:
Newscaster:...and that's the end of the news.Now we'll go over to the weather center for the weather forecast for the whole of the United Kingdom.
Weatherman:Good evening,Due to the depression lying off the north England and the high in the south of England, tomorrow's weather will be variable across the country.Starting ,then,in the southwest,it'll start cool and become warm with long periods of sunshine.Around London and the southeast, the day will be dry but cloudy at times.In the Midlands, it'll be cloudy all day with showers at times.Moving over, then, to Norht Wales,there may be fog patches over the mountains for probably much of the day,while in South Wales it'll be generally windy.In the northest,it'll be cloudy all day, some rain everywhere and it'll be heavy at times.Furhter north in Scotland, we can expect sleet in those areas south of Edinburgh, while in the very north of Scotland and the Hebrides, there'll be snow on high ground.Now in Northern Ireland, there's a possibility of rain, and it'll certainly be very cold.that's the end of the weather forecast.
