The temperature of the earth has risen. Earth's temperature has increased by 1.4 ° F after many years, and is expected to be increased again from 2 to 11.5 ° C for a hundred years to come. Few minor changes to the average …show more content…
Carbon dioxide can stay in the room for almost a century, until the earth is heated further in the future. The warmer the conditions, the higher the risk to suffer from climate change and the earth system worse. Although it is difficult to predict the exact impact of climate change, what is clear now is that our climate is no longer a reliable guide to predict what will happen in the future.
The intergovernmental panel on climate change was set up in 1988 under the auspices of the World Meteorological Organization (WMO) and UNEP, the Intergovernmental Panel on Climate Charge (IPCC) brings together the majority of the world’s climate change scientists in three working groups which are on climate science, impacts and economics and social dimensions. They have produced assessment reports in 1990n, 1995 and 2001 which are regarded as the authoritative scientific statements on climate change.
The reports are carefully and cautiously drafted with the involvement of government representative and represent consensus view. The fourth assessment report published in February 2007,concluded that warming of the climate system is unequivocal as is now evident from observations on increases in global average air and ocean temperatures, widespread melting of snow and ice rising global sea level (IPCC, 2007)
