Cause of global warming
Everyone now has recognition to “Global warming”, and it acts because the concern for the environment and it begins to work in the shape that sticks to our life.
Then, what do you cause as for “Global warming”?
Also because “Global warming” paid attention to all over the world is a content exactly related to the human race’s continuing, various discussions are done.
The theory of the main style is the one as the cause of “Global warming” by having exhausted “Heat-trapping gas” along with the industrial activity that has been done so that we human races may develop.
The heat-trapping gas that the human race generated is assumed according to AR4 (the fourth evaluation report) issued by “Intergovernmental Panel on Climate Change” and the probability of cause of “Global warming” is assumed to exceed 90%.
AR4 (the fourth evaluation report) is this consolidating an academic finding of now most, and the report acknowledged worldwide.
Therefore, when the discussion of relating to the cause of “Global warming” is executed, this report is a main axis.
However, meteorological observation data here and there and a huge calculation are needed all over the world for the root cause analysis on Global warming.
The analysis is done by various climate models by the use of data that observes the temperature directly and the temperature presumption data, etc. for the past tens of thousands of years for the calculation.
It is assumed that the influences such as carbon dioxides and methanes that are still a kinds of the heat-trapping gas as the cause of “Global warming” are large as a result of the analysis.
It is presumed by another that there are various causes like human race’s land development and the use of the aerosol, etc.
