Det ligger til rette for tidenens metanutslipp i Arktis
Mens debatten ruller mellom frontene om vi skal tro på dette eller ikke, går naturen sin egen vei. Det er tøft å ta det inn over seg – men rullgardinen bør nå gå opp hos politikere og menigmann. Les ivertfall dette innlegget, og gjør et grønt valg 9. september:
This commentary does not dwell on “doomsday” rhetoric. But humanity is teetering much closer to oblivion than what has been “getting through” in the shallow coverage offered by mass media, and there is a moral imperative to issue a warning. Mass extinction – especially self-imposed – is not a “pretty” concept and the use of a few graphic images is necessary to both convey a reality that may be forcing itself upon us and to penetrate the shield of denial. The voices of scientists pressing on this front deserve to be amplified. Their observations and concerns are presented to the reader, who is invited to evaluate whether any “alarm” is justified. Humanity is standing on the very edge of a cliff, and if we fall off it will be a one way ticket to Hell.
Despite the looming shadow cast by this danger, it has yet to make its way into public consciousness. Even the world-wide environmental movement has continued to focus on human-generated emission of global warming gases and has not grasped the dire implications of the accelerated catastrophe which could ensue if nature’s own stockpile becomes activated – an immense storehouse containing far more carbon than humans have generated since the onset of the industrial age. Though the sweeping scale of this existential threat combined with its potential irreversibility – once triggered – may be leading to psychological denial, the reality of the danger compels humanity to take all precaution and spare no expense in both understanding and reducing it. Yet the response so far points to an unspeakably tragic moral collapse. Every single segment of our society that should be either sounding the alarm or taking definitive action to prevent this global catastrophe is presently looking the other way. This commentary examines such failure in Part Two, but first explores the nature and magnitude of the danger itself.
Geological Record Points to the Destructive Power of Methane -
Although carbon dioxide persists much longer in the atmosphere, the Intergovernmental Panel on Climate Change (IPCC) states that methane is a full 72 times more powerful during its first 20 years. It is the prevailing view of the scientific community that earlier major releases of this gas resulted in the most catastrophic wipe-outs of life in planetary history. Two critically important British documentaries explore the scientific inquiry linking methane to both the Permian  and PETM  mass extinction events. Les hele innlegget på Arctic news her.
