CAUSES , EFFECTS , AND FUTURE OF GLOBAL WARMING

Overview of Global Warming

In the 100 years ending 2005 , Earth 's surface temperature has increased from 1 .33 to 0 .32 ?F . According to the Intergovernmental Panel on Climate Change (IPCC , such is due to the increase in anthropogenic greenhouse gas concentrations . Thus , the increase in the average measured temperature of the near-surface and oceans of the Earth beginning from the mid-20th century to its certain projected continuation has been referred to as

Global Warming (Harvey , 2000

During the pre-industrial times until 1950s , solar variation in concurrence with volcanoes had showed small warming effect . On the other hand , from 1950s onwards , a small cooling effect had transpired (Rosser and Billington , 2008 ) Academies of science and various scientific societies as well as national academies of science of major industrialized countries have come up with these conclusions although some individual scientists went against them

Based on the climate model projections presented by the IPCC , the average global surface temperature is most likely to increase in the 21st century from 2 .0 to 11 .5 ?F . The values were results of the utilization of models with diverse climate sensitivity and various scenarios of future greenhouse gas emissions (Harvey , 2000 ) Most studies are now focused on the period up to 2100 however , sea level increase and warming are expected to prolong for more than a thousand years regardless if the levels of greenhouse gas are stabilized
