Scientists: Global warming could lead to mass human extinction

I'm an independent thinker as well, but that doesn't mean that I ignore scientific fact. 

The group to which you belong is global warming deniers, who like Holocaust deniers or people who claim moon landings to have been staged are aggressively denying reality, in your case with disastrous effects on the world.

I do not expect you to go away. I expect to help people see through your kind.

On the issue of global warming skeptics There is no simple answer to complex problems and this is also true for global warming and consequent climate change. Science is not and can not be based on faith and belief statements. Scientific knowledge evolves over time, as new discoveries, improved methodologies, analytical tools and mathematical models increasingly detailed and complex. The scientific knowledge on global warming and climate change has, over the past 10 years, becoming increasingly consistent precisely because this process of knowledge development. There are skeptical views on the climate, but they are isolated and with large differences in concepts and methods of research and scientific documentation. Studies of the IPCC, with the active participation of over 2,500 scientists and more than 600 institutions (universities and research centers) use mathematical models with nearly a thousand variables and factors analysis. Moreover, in the last five years, published over 500 scientific papers, effectively documented with results, methods and instrumental peer reviewed. The mathematical models are constantly evolving, incorporating new data and analysis factors. It is an excellent demonstration of knowledge in construction. So we're talking about a huge scientifically demonstrable and certified consistent result. The warming skeptics are few published works and, in general, without peer review (peer review, refereeing, in English). Furthermore, using isolated factors or a few variables, which concentrates the results toward the desired focus. Recent interviews published in major media vehicles, express opinions in global warming, but do not present any argument can be questioned or discussed based on research or scientific studies actually documented. Opinions are based on 'may be', nothing more than that. I suggest you access the tags mentioned below are available on the Portal EcoDebate and with a little research could have a small idea of the amount of available studies and widely accepted in relation to global warming. Respect the right of opinion and the right to question global warming but, in my opinion, deny from isolated events or factors, not present studies and research with the volume, density and coverage relatively proportional to that presented by the international scientific community is a rudeness and a disregard for science and for society. Denying global warming is easy, it is difficult to document and demonstrate scientifically the foundations of the negative.Henrique Cortez, environmentalist and coordinator of the <a href="www.ecodebate.com.br/">Portal EcoDebate</a>.<a href="www.ecodebate.com.br/tag/pesquisa/">Pesquisa</a><a href="www.ecodebate.com.br/tag/aquecimento-global/">Aquecimento  Global</a><a href="www.ecodebate.com.br/tag/mudancas-climaticas/">Mudanças  Climáticas</a>
