weather is an important part in farming and changes in temperature will strongly affect crop growth.

For the UK，temperature rises are likely to mean the crops normally growing in the south of the country will be able to be grown further north.The UN believes there will be a shift northwards of between 200 and 300 kilometers for every degree of warming.This would be similar to the south of England in 2060，having the kind of weather the Loire Valley，in France，experiences now.

However，if farming practices do change in this country，procedures will have to be put in place beforehand as introducing something new of farmland involves a lot of preparation.Also，irrigation systems may need to be improved so rain from winter can be stored for the summer as it is hotter.

Researchers are finding that pests，such as aphids，are starting to hatch(孵化) earlier in the year.In the last 10－15 years they’ve been arriving in springtime and the population of aphids appears to be growing too.
