Climate change can also be caused by human activities, such as the burning of fossil fuels and the conversion of land for forestry and agriculture. Since the beginning of the Industrial Revolution, these human influences on the climate system have increased substantially.
As weâve already established, climate change occurs when the factors that influence it changes. Changing climate on a global scale, though, can only occur when the amount of heat in the Earthâs system changes by either being added or released. Warming climates are the result of either an increase in heat entering the Earth or a decrease in heat released from the atmosphere.
