Democracy, with all its problems, also has its paradoxes. Regular elections lead to short government life-time. This seems to result in more emphasis on short term goals and safer issues that appeal to populist issues.
As a result, anthropogenic global warming has recently become a major concern for humanity. Such concerns are supported worldwide by the wide majority of climatologists.
Global warming is an increase in temperature in addition to the natural greenhouse effect. The greenhouse effect interacts with other planet-wide influences such as the Milankovitch cycles in order to produce long-term climate movements.
Many gases contribute to the greenhouse effect, some of the most important being water vapor, methane and carbon dioxide. The ability of these gases to act as greenhouse gases can be shown in a laboratory. The increase in temperature has been caused by the increase in greenhouse gases.
Note that the statement that The increase in global temperature correlates with the increases of greenhouse gases is only true on a very broad timescale: GHGs have increased roughly exponentially but the temperature signal is far noisier, and displays almost no correlation with GHG changes on an annual basis, as expected.
This is due to a variety of factors, from intrinsic noise in the climate system to the existence of other important forcing factors most notably sulphate aerosols and global dimming, which are cooling factors.
Also note that while water vapour is correctly listed as a GHG, the human emissions of water vapor are not important in forcing climate change; water vapour is best thought Global warming hype or reality as a response to temperature change rather than a cause, because its atmospheric lifetime is very short about 10 daysunlike other gases such as CO2.
The International Energy Agency suggests that the window to prevent this from occurring will close by a view shared by the OECD. CO2 emissions have been stabilizing but methane emissions have risen dramatically during the past ten years for unknown reasons. This undermines efforts to combat global warming and there is a risk of an uncontrollable run away greenhouse effect.
The error bars, particularly on the negative components, are currently the focus of much climate research in order to improve predictive climate models.

A scientific consensus is reached when the vast majority of the scientists involved in a discipline broadly agree on the interpretation of the evidence pertaining to a specific scientific question. When this occurs the case can be considered to have been demonstrated and the burden of proof then falls on those who would dispute the consensus.
The following national and international organizations are part of the consensus that global warming is a real phenomenon for which humans are responsible: Though some have taken non-committal stances, the vast majority of scientific bodies are convinced by the evidence.
Anyone who, even after the occurrence of extreme weather events that seem to intensify yearly, does not see the validity of decades of scientific documentation that catalogues the existence of global warming, is a lost cause. Simply put, time is of the essence. Ongoing experiments aim at obtaining the CO2 from clean coal plants equipped with carbon capture technology.
Although the technology itself seems to work  it is not clear how sequestering coal CO2 to help produce more oil will affect atmospheric CO2. Scrubbing atmospheric CO2[ edit ] Air capture technology to collect CO2 is routinely used in spacecraft and submarines. However, it requires energy to operate and a study estimated that processing the whole atmosphere would not be cost-effective.
One of the authors noted that planting vegetation is more feasible but would require a significant amount of land. One good example of plants that consume plenty of CO2 are pine trees used in farming. Though they tend to use the nutrients in the ground, in theory they can be replenished from biosolids refined animal feces.
Decomposing plants release CH4, an even worse greenhouse gas than CO2 and there is simply not enough storage on earth for all the wood forests of the needed magnitude would produce. However, we could bury the resulting biomass underground, in effect recreating the origin of the fossil fuels that got us into this mess in the first place.In this week’s eSkeptic, Donald R.
