We say 'weather' when we talk about how the weather is today. In some places the weather is the same all day. In other places there are several kinds of weather in one day. We use 'climate' when we talk about the usual weather and temperature of a place. We must record the weather every day for a long time. Then we know the climate of a place.
The climate is very cold in winter and warm in summer. In winter the animals and birds are white. In summer they change their colour to brown and grey. The winter is very long (8-9 months). In winter we cannot see any plants. There is a short summer (about 3 months). It is very beautiful. There are a lot of flowers and grass. There are no trees.
