Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century, and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C , with about two-thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels. These findings are recognized by the national science academies of all major industrialized nations.
