Climate change is a long-term change in a region's climate. This includes the entire Earth changing from what is considered normal. These changes can include temperature, wind patterns, or precipitation (rain and snow) levels. Climate change takes place naturally over time because of many different factors, like the distance from the Earth to the Sun, the intensity of sunlight, and the amount of particulate matter in the air reflecting sunlight back into space. Today, scientists agree that natural processes can be sped-up by human activities, like burning fossil fuels and land-use activities. This causes a higher rate of change compared to what happens naturally.
