Global warming refers to an increase in average global temperatures, which in turn causes climate change. Climate change refers to changes in seasonal temperature, precipitation, wind, and humidity either globally or regionally. Our atmosphere is made up of gases, such as nitrogen, oxygen, and CO2, and water vapour, which act like a “blanket” draped around the planet. Some of these gases—such as CO2, water vapour, and methane—absorb heat, reducing the amount that escapes to space, and increasing global temperatures. Without this process, the temperature of Earth’s atmosphere would average about 30 degrees Celsius colder than it is today, making it difficult for Earth to sustain life as we know it. However, if this blanket were to become too “ effective” with too many gases trapping too much heat, Earth would be uninhabitable.
