Global Warming Two thousand years of average temperatures, according to several reconstructions, calculated in local regression decadal, ending in 2004. Global warming is a term used to refer to the alleged phenomenon, as some (see below) – a rise in average temperature of Earth’s atmosphere and oceans, either from 1850-coinciding with the end of the Little -Ice Age either in relation to longer periods . This increase would have been accentuated in recent decades of the twentieth century and the first century. (see op cit). Terms commonly associated are: Climate change, which means any change in climate. Anthropogenic climate change, which consider the influence of human activity and greenhouse effect phenomenon that refers to the retention-by certain atmospheric gases-energy part of the soil emitted as a result of being heated by solar radiation.The UN body responsible for the analysis of relevant scientific data – IPCC (Inter-Governmental Panel on Climate Change or Intergovernmental Panel on Climate Change) – argues that “most of the observed increases in average temperatures since the mid-balloon twentieth century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations. “. This is known as the “anthropogenic theory” and predicts that global warming will continue if they do emissions of greenhouse gases. Any climate change also involves changes in other variables. The complexity of the problem and its multiple interactions cause the only way to assess these changes is through the use of computer models that try to simulate the physics of the atmosphere and ocean and have limited accuracy due to ignorance of the operation of the atmosphere.The Kyoto Protocol, agreement resulted in the Convention United Nations Framework on Climate Change adopted at the United Nations Conference on Environment and Development promotes a reduction of pollutant emissions (mainly CO2). The protocol has been branded as unfair at times, citation needed because the increase in emissions is traditionally associated with economic development, bringing the nations to which most affect the performance of this protocol could be those less developed areas . However, in that Protocol in developing nations (including China and India) are exempt to contain its greenhouse gas emissions. Beyond the general scientific consensus concerning the acceptance of mainly anthropogenic origin of global warming , there is an intense political debate about the reality of scientific evidence of it.For example, some among these politicians think that the alleged climate consensus is a complete fallacy and in January 2009, the Senate Republican minority in the United States drew up a list of more than 700 scientists who dissented from anthropogenic sources of change temperature of the Earth, In 2009 it was discovered the alleged Climagate scandal, which allegedly showed that scientists at the Climate Research Unit at the University of East Anglia have manipulated the data for which matched the warming theories . . However, independent scientific observers questioned that interpretation. Nature says: “What emails do not show, however, is a big conspiracy to make global warming …” and New Scientist notes that “it has been shown that in emails hacked something implies an undermining of any scientific conclusions. .Continuing to examine some of the suggestions from skeptics of anthropogenic global warming, the article shows several examples of lack of fit with the facts and rigor – for example, the presentation of opinion pieces of journalists as “peer-reviewed scientific articles “- and concludes” we let the readers draw their own conclusions about who to trust. ” Some political opponents of the proposal seem to fear thatthe proposals for action to prevent consequences of the phenomenon are politically motivated.For example, the Viscount Christopher Monckton, businessman, politician and British journalist who likes self-described “expert on climate change” despite lacking any scientific qualifications, he argues that the purpose of “treaty” (which in his opinion would inevitably signed in Copenhagen (see Conference on Climate Change UN 2009) is to impose a world government, led by, among others, would be Obama who, in the opinion of Mr. Vicomte, a communist sympathizer.
