Why is it so hard to admit the truth?

I was reading an article on National Geographic published in 2000. It is called "The New Cold War - Stalking Arctic Climate Change by Submarine", it was written by Glenn Hodges and talks about a science project to study the arctic so that we can know more about the relationship between global warming and Arctic iceburg melting down. It is an very old article published nearlly 7 years ago, you really don't expect to learn anything new there, it turns out otherwise.

Here I quote one paragraph from the article:

"Given that the Poles are widely seen as bellwethers of global climate change, this all looks very damatic. But it may be just another imagined monster lurking in the blank spots of our knowledge. Perhaps the water regularly warms and cools and the ice regularly thins and thickens as atmospheric pressures and water currents oscillate. There's evidence to suggest that, but it's not conclusice. ......So the questions remain: Will currents and temperatures revert to more familiar patterns? Or is the Arctic showing signs of global warming?"  "(Drew Rothrock, University of Washington reserch scientist.)I don't think you'd find many Arctic scientists willing to say, 'Yes, it's all melting up there, and in another decade we won't have any sea ice.'".

So how do scientists think about the issue now? Arctic Speciallist Mark Serreze said

"If you asked me a couple of years ago when the Arctic could lose all of its ice then I would have said 2100, or 2070 maybe. But now I think that 2030 is a reasonable estimate." 

A 2004 essay by Naomi Oreskes in the journal Science reported a survey of 928 abstracts of peer-reviewed papers related to global climate change in the ISI database.^[18] Oreskes stated that "Remarkably, none of the papers disagreed with the consensus position. ... This analysis shows that scientists publishing in the peer-reviewed literature agree with IPCC, the National Academy of Sciences, and the public statements of their professional societies." (Wikipedia)

Do you see how far we have come through in the last years? If you think you can still put out some argument againest this, then please let the data and facts talk themselves:

But are we really admiting the truth? Well, you wish! I just saw this piece of news CNN weatherman considers Gore's An Inconvenient Truth fiction. Or you can watch the video bellow:

I know that there are some debate about the exaggeration of data and fact in Al Gore's movie, but you know what? I believe "矫枉必过正", which means: If you want to correct something, normally you need to act excessively to achive so. When Rob Marciano or other critics talks about flaws in the movie, they may not intend to overthrow the whole movie and the global warming fact, but with the aid and inappropriate propganda of mass media, our mass audiences will get the impression that "Al Gore is wrong!" and eventually "Global warming isn't happening!"

With the obstructions of the bureaucracy, it is natural that government will not actively involved in the fighting againest global warming! So this is what you are seeing: the public NGOs are taking the centre stage while those big government leaders are spitting at others and taking photos.

To be honest, I am very pessimistic about global warming! I really don't think we have a chance to make things right, because we have already run out of time! Hopefully I am wrong!
