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.

Due to an increase in drought and heat waves，the types of crops grown in the UK will have to change，which doesn't have to be a bad thing for us.Products which haven't been farmed over here before，such as sweet corn，sunflowers，and maize for cereals，could all provide new business for farmers-certainly in the south east.

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.

Aphids are a real problem as they can cause so much damage to crops and if they're arriving earlier in the year they can get the produce when it's very fragile-causing more damage than they used to.
