Misato NotoThe term climate change refers to a significant long-term variation in the regional or global average of weather conditions. These include temperature, humidity and rainfall patterns. It also refers to the effects of Earth’s warming, such as rising sea levels, loss of polar ice and mountain glaciers, and changes in vegetation blooming times.
Changes in Earth’s climate have been caused by two factors. The first is natural climatic variability, which has taken place over hundreds and thousands of years. They appear in volcanic eruptions, ocean currents, orbital changes and variation in solar radiation, for example. The second is human action. Particularly, the burning of fossil fuels intensifies the greenhouse effect and contributes to raising the planet’s temperature.
