The Earth’s climate has always been variable, this has been shown through the Earth going through severe stages of dramatic climate. The greatest example of this are the 5 major Ice Ages that have occurred throughout the Earth’s history. Many scientists believe that human influences have had a major impact the temperature of the Earth since the start of the Industrial Era. The main influence is the enhanced greenhouse effect, this has occurred from fossil fuels being released into the atmosphere and deforestation for agriculture, urbanisation and industrialisation. The system that the enhanced greenhouse gases are affecting is the Carbon Cycle, by putting more carbon in the atmosphere, human activity is contributing to the warming of the Earth.
