[3][4][5][6] These findings are recognized by the national science academies of all major industrialized nations.[7][A] Climate model projections were summarized in the 2007 Fourth Assessment Report (AR4) by the Intergovernmental Panel on Climate Change (IPCC). They indicated that during the 21st century the global surface temperature is likely to rise a further 1.1 to 2.9 °C (2 to 5.2 °F) for their lowest emissions scenario and 2.4 to 6.4 °C (4.3 to 11.5 °F) for their highest.[8] The ranges of these estimates

(about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.” IPCC, 2007: Climate Change 2007: The Physical Science Basis.

comparing these recordings scientists have found that the earth’s annual average temperature has increased by approximately 0.6 degrees Celsius between the years 1861 and 2000, with major increases occurring in two periods: 1910 to 1945, and 1976 to 2000 (IPCC, Climate Change 2001: The Scientific Basis: 2001). It is believed that the climate is changing due to the greenhouse affects. The plant’s surface temperature has increased due to the cause of absorption of radiation by gases in the atmosphere, including

gas then absorbs the light and is remitted back to the Earth's surface and warms it even more. Another cause of Global Warming is the emissions of greenhouse gases due to the increase in technology that humans have developed. One recent study by the IPCC (Intergovernmental Panel on Climate Change) said that unless governments do something to restrict the emissions of greenhouse gases to a lower level, global temperatures could rise 1.6 to 6.3 degrees Fahrenheit by the year 2100. This would represent

is the reason why nowadays a lot of issues are decided or determined at a transnational level, either by states acting collectively (such as G7 and G20) or as rules created by transnational regulatory authorities ( main examples are the WTO and the IPCC). As there is no global government, global governance typically involves a range of actors including states, as well as regional and international organizations. However, a single organization may nominally be given the lead role on an issue, for
