In the 1500s, South American fishermen said that the sea became warmer every few years. They gave this special event a Spanish name ’El Nino’, meaning ’the baby’. It is called ’the baby’ because it arrives around Christmas.
El Nino is a huge area of warm water in the middle of cold water in the Pacific Ocean. It happens every two to seven years. It moves around the ocean and becomes bigger and smaller at different times. This warm water affects the weather. It is always raining over El Nino. El Nino contains a lot of energy. Scientists think this energy is formed when wind comes from the northern half of the world. The winds blow across warm sea water in the south. When the strong wind hits the warm water, violent weather happens. Scientists think that El Nino existed for many thousands of years.
El Nino affects every person in the world because it affects the entire world’s weather. It can bring the rain that farmers need. It can bring storms that destroy homes. It can mean that fishermen cannot catch fish, and it can bring floods. There is nothing we can do about El Nino. It is an event of nature. We can help the world’s weather by trying to stop the greenhouse effect and air pollution. The most important job for scientists is to learn how to predict when El Nino is going to bring dangerous weather. Then, people can try to prepare for storms, floods and droughts. New technology like satellite pictures and temperature measuring equipment can help. Still, it is very hard to say when or where El Nino will cause damage.

Dear Estelle, Saturday, 5th June
I hope you’ re well and not working too hard! I’ ve been revising for my exams now for the last two weeks. That’ s why I haven’ t written for such a long time.
Since the beginning of this year we’ ve been doing a project called ’ World Class’. Have you heard of it.’? Not everyone in the class could take part, but luckily I could. The school chooses a ’twin school’ (姊妹学校) in a different area of the world. Our head teacher chose a school in Uganda. They gave us someone to write to from that school. For three months, I’ve written to a girl called Louisa, who is the same age as me.
It’ s been more interesting to hear about her life. She’ s told me all about her school and described her daily (日常的) life. I can’ t believe that her School doesn’ t. have any electricity. She goes to ’school from eight o’ clock in the morning until six. O’clock. in the evening. I can’ t believe how lucky we are here! She’ s also told me that she often can’ t go to school because she has to look after her baby brother and sister. She’s tried to teach me some of her language and it’ s really difficult.
I love it because it’ s the first time I’ ve thought about what life must be like somewhere else. I can’ t believe people miss classes here when everything is so easy for us. I think more people should help out with projects like this. At the weekend we’ re going to have a sports day to help raise money to send to the school. Perhaps one day I’ll be able to go to Uganda and meet Louisa myself--who knows?
Lots of 1ove,
Suzanne
