Climate and weather

1) Earth is unique among the planets in the solar system. One of the most unique features of Earth is the presence of a stable atmosphere. The various gases that surround a planet make up its atmosphere. Earth's atmosphere shapes our weather, climate, and vegetation patterns and makes life as we know it possible. Without air there would be no day-to-day weather changes. It would be extremely hot during the day and very cold at night. And, there would be no oxygen and no carbon dioxide to support human and plant life.

2) A great "ocean" of gases surrounding the earth for thousands of miles forms the earth's atmosphere, usually known simply as the air. More than 98 per cent of the gases that make up the atmosphere, however, are found within 26 km of the earth's surface. Farther above the earth, the gases – and the air – gradually thin out. Air in its natural state is a colorless, odorless, tasteless mixture of gases. Nitrogen makes up 78 per cent of dry air, oxygen makes up 21 per cent, and other gases such as carbon dioxide, helium, and ozone make up the remaining 1 per cent.

3) Along with gases, air nearly always contains small amounts of water vapor, dust, soot, pollen, seeds, and other particles. Winds, forest fires, and volcanic eruptions sweep many of these particles into the air naturally. Other particles, release from chimneys, smokestacks, automobiles, and other polluters. Together, these particles create polluted air, such as the haze and smog that hangs over many cities today.

4) Weather is the condition of the atmosphere for a short period of time at a specific location. The average of daily weather conditions over a long period of time is known as climate. Certain location and place factors influence the distribution of climates over the earth's surface. These factors, known as climatic controls, are latitude, altitude, and proximity to land and water.

5) Climate has relationships to all other parts of the earth – its land, its water, and its atmosphere. These relationships work in two ways. Land, water, and the changes that take place in the air play their parts in shaping climate. At the same time, climate plays its part in helping to shape landforms and soils. Climate helps to keep the water cycle working. The relationships among land, water, air, and climate go even further. They have a direct influence on the kinds of plants and animals that live in a region. Climate also places limits on people's choices about how they will use the land, the water, and the forms of life found in a region.

6) Today scientists know some things about climate changes in the past. There were periods when climates in the middle and high latitudes were warmer than they are today. There were other periods when climates outside the tropics were much cooler than they are today. These cooler periods usually resulted in the buildup of ice on the earth. Packs of ice covered large parts of the world's oceans and lakes. But always, the glacial periods were followed by warmer periods. This cycle of warming, cooling, and warming again has repeated itself several times in the past. The earth's last glacial period gave way to a warming period about 11,000 years ago.
