A weather pattern

These days, global weather patterns have changed rapidly compared to the last century and these changed weather patterns have caused many serious natural disasters worldwide. what are the main reasons of these changes?

The Greenhouse effect is one of the key factors of changing global weather patterns. Since the Industrial Revolution, many countries have industrialized and expended industrial zone. Some of these industries inevitably use air pollution- inducing fuels. In addition to this, most people in industrialized countries drive a car almost every day, emitting much carbon dioxide that is one of the main gases responsible for this effect. This causes the "greenhouse" to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter. As a result, the temperature of earth is higher than before, a phenomenon called global warming. Global warming refers to an average increase in the Earth’s temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns and a wide range of impacts on plants. These changes can also result in melting Arctic ice and rising sea levels. Finally, it causes changes of weather patterns throughout the world.
