Thousands of studies conducted by researchers around the world have documented increases in temperature at Earth’s surface, as well as in the atmosphere and oceans. Many other aspects of global climate are changing as well. Human activities, especially emissions of heat-trapping greenhouse gases from fossil fuel combustion, deforestation, and land-use change, are the primary driver of the climate changes observed in the industrial era.

Issues related to climate change

• global warming- increase in temperatures in the Earth's surface, oceans and atmosphere
• deforestation

• land use change
• impact to society - human health, agriculture and  food security , water supply, transportation, energy, ecosystems
