We can't stop global warming

Résumé du document

Barack OBAMA, the candidate running for nomination by the Democratic Party said in a speech in April 2006, "All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon, the man-made natural disaster". Global warming is a phenomenon mainly caused by mankind, but stopping it is impossible for several reasons. Firstly, the phenomenon is too engaged to be stopped. Secondly, it is possible that global warming is a natural phenomenon too, even if there is no doubt that mankind is the cause of an acceleration of the process. In that case, stopping global warming would be impossible for humans. And finally, it appears that the policies implemented to control global warming are not sufficient and/or ineffective.

[...] Coal, first source of energy, is extremely polluting and the increase in the standard of living results in a request increasing for car, air- conditioning Today, scientists and observers agree for saying that it is already essential to go beyond the Protocol of Kyoto, i.e. even more severely to limit greenhouse gas emissions. That means for example to consume less coal or oil. However, the energy policy of the government of the United States stresses especially the use at excess of this last source of fossil energy.

[...] That means for example to consume less coal or of oil. However, the energy policy of the government of the United States stresses especially the use at excess of this last source of fossil energy. Policies and measures implemented to protect the environment and in the same time to try to slow down global warming are ineffective and insufficient. Environmental policies are often restrictive measures: protecting the environment is associated with paying taxes and with a lot of prohibitions. I think that it isn't the best way to protect the environment and that we won't be able to slow global warming down if the legislation doesn't change its way of action. [...]

[...] And finally, it appears that the policies implemented to control global warming are not sufficient and/or ineffective. Firstly, it appears that it's impossible to stop global warming because it's too late and because the process is too engaged. Even if greenhouse gases levels became stabilized five years ago, global temperatures would still increase by the end of the century and sea level would rise. Stopping greenhouse gases emissions is not enough to slow down climate change because the ocean responds slowly to perturbations. [...]

[...] So even if humanity stopped burning fossil fuels tomorrow, the planet would continue warming for decades. So far, the greenhouse gases released during two-plus centuries of industrialization have increased global temperatures by about one degree Fahrenheit and raised sea levels by 4 to 7 inches, according to Mark Hertsgaard,a journalist in charge of the ecological questions for the american magazine The Nation. Secondly, to hope to stop global warming, it would suppose that global warming is only caused by human actions and yet it isn't totally the case: we haven't any proves that there isn't a natural cause to global warming and that human actions are the only causes.
