eThe phrase global warming refers to the documented historical warming of the Earth’s surface based upon worldwide temperature records that have been maintained by humans since the 1880s.It is the increase in the average temperature of the Earth’s near-surface air and oceans.In the last 100 years‚ this temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades.According to the exponentss of the concept‚the likely effects of a further
