the reality is: we are already living in
weather
in which man has never lived .
wars between states, to lay hands on water, fuels, scarce metals. We will not follow so the percentages established in cutting emissions in the comparison between the economic needs, environmental and international power relations, but we will try persuasion of a conscious reasoning.
Each new report from the climate of each latitude makes us understand that climate change is the most distressing problem with which we have ever faced. It seems such that we are already living in atmospheric conditions in which human beings have never lived before, we are, in fact, entered into an unknown territory climatically. Climate change is proceeding faster than expected: the goal that until yesterday seemed sufficient, a ceiling concentration of CO2 in the atmosphere of 450 parts per million, can not protect us from the risk of catastrophe.
In the study "Climate change and the environment in Antarctica" written by nine scientists (including the Italian Guido Di Prisco), with the help of over 100 researchers, on behalf of the International Scientific Committee for Antarctic Research, it is argued that the seas will rise by at least 1.4 meters. It is not scientists against scientists. The diversity of estimates about the rapid melting of Arctic sea ice than the Antarctic. Paradoxically, Antarctica has remained unchanged over the past decades for the ozone layer affected by industrial emissions, but all this is ending.
"The fear, though fallen into some disrepute moral and psychological, is the responsibility of just how much hope and we must make the case, for fear is now more necessary than at any other time when, animated confidence in the smooth running of human affairs, you could consider it with a sufficiently weak and cowardly neurotic "
Climate change also causes the weakening of the Gulf Stream, much faster of what was thought until now, paradoxically, means that global warming could lead to areas of northern Europe and other areas in the world freeze - even if the trend in the long run, would be to suffer a Rising temperatures.
What is even more alarming is that these and other changes could clearly take place much faster than we think.
I "rollover" climate that lead to very different climatic conditions, seem to have taken place over the last ten years.
In the meantime we are already witnessing a new trend in the climate in which there has been an increase long periods of drought alternating with violent storms, floods - a trend that will only get worse with increasing global temperatures.
Major baskets of the world, such as the American Corn Belt, the Canadian Plains and the Australian wheat belt, suffered major droughts in recent years.
These areas are becoming drier, with a corresponding reduction of the world's food supply. In addition, the resources of the world's major rivers are located in mountain areas such as the Rocky Mountains in the U.S. and Himalayas in Asia.
In spring masses snow and glaciers melt, filling the rivers, however, the rains are increasing and replacing The snow and glaciers are retreating, and this causes a corresponding reduction in the seasonal flow of rivers and the ability of farmers to irrigate their crops.
If this were not enough, rising sea levels is estimated - by the Intergovernmental Panel on Climate Change (IPCC) - that 30% of agricultural land worldwide could be saturated with brackish water and flooding during the destructive storm-surge and the resulting tidal waves.
We must also understand that climate change has repercussions in every aspect of our lives, not only in providing food, but on our health, as the temperate zones will be invaded by vectors and pathogens tropical diseases and, more generally, forms of viral mutants. And the economy will be seriously affected.
We must also consider that even without climate change, we must replace our oil consumption as the world's oil reserves, convenient and accessible, are rapidly being exhausted and it is expected that the production reaches its peak within the next decades . On the other hand, demand is soaring, especially as a result of rapid industrialization of China, India and other countries in Asia.
Given the economic and financial relationship with the United States and, more generally, with the West, prices will be subject to speculation, unparalleled in the reserves and shortages will be commonplace.
What to do?
Clearly the first thing we need to disengage from our oil addiction and learn to make much less. The deficit in oil stocks may cause a serious recession, and a permanent deficit could cause a real economic collapse since the oil is not only a fuel for transport but also the chemical basis of most of the products processed.
This means above all rapidly increase energy efficiency. The real cuts in emissions can be achieved by eliminating waste and inefficiency. The energy renewable energy, especially wind power, now very cheap, should play a role such as solar.
Two regions of Spain, Navarre el'Aragona in ten years came to 70 percent of electricity from clean sources. Why not do the same?
Jeremy Rifkin and hydrogen as fuel economy of a new industrial revolution, and then sent on three-wheel drive: renewable energy, sustainable buildings and smart grids to distribute energy in the form of the web, moving the speculative oligarchs from power of fossil energy to people and then to community participation.
It is not just about oil. The natural world, especially its forests and all other vegetation, wetlands, its land and especially its oceans are able to absorb up to 50% of emissions of carbon dioxide. As we all know, are being destroyed at an unprecedented rate and this can only dramatically reduce their power to absorb the carbon dioxide emissions. The Hadley Centre has considered this in a recent model, which led to the revision of the estimates made dall'IPPC, which said that average temperatures could rise up to land 5.80 Celsius by the end of this century.
In order to save our planet, this destruction must end and end very quickly while the rest of the natural world must be conscientiously protected. A strict conservation, not development, must be on the agenda. For example, you need not longer afford to cut down natural forests and forestry in particular tropical forests.
Other activities involving the destruction of forests, such as the activities of mining and construction of large dams, should be severely reduced, while on the contrary, we must significantly increase the areas of undergrowth. The agriculture industry will have to do without heavy machinery and should reduce their arsenals, full of toxic chemicals that destroy ecosystems rapidly transforming the fertile ground in dust and releasing large amounts of carbon into the atmosphere.
The real problem you should tackle is: how long will it take to secure this necessary transition? The political agenda moves on extensions to the present time is not credible.
The scale of implementation for decades is too long because our destructive activities can transform the natural world into a source of carbon dioxide emissions rather than a physiological absorber, so rising temperatures and if temperatures continue to rise at current speed, this could happen within the next 30 - 50 years and we could find to an uncontrollable point to the inexorable rise in temperatures. For this reason, we must take appropriate action now. There is no time to lose.
Even if we reduce emissions by 60% -80% to prevent the destabilization of climate, surface temperatures continue to rise over the next 150 years, at which time carbon dioxide remains in the atmosphere and for much longer, in the seas and oceans. Consequently, we can only hope that rising temperatures will slow enough to ensure that our planet can remain a livable place, once the weather should stabilize.
Fear can become a political liability. It is the belief of the philosopher Hans Jonas: "The fear, though fallen into some disrepute moral and psychological, is the responsibility of just how much hope and we must make the case, for fear is now more necessary than in any other age in which, inspired by confidence in the smooth running of human affairs, one could regard it with a sufficiently weak and cowardly neurotic "(The principle of responsibility, Einaudi, 2009). We must therefore create a kind of society that minimizes the use of fossil fuels and sustainability in redefining the relationship between culture and nature.
The only type of company that can meet these conditions is a Community company in which economic activities are conducted on a smaller scale, focusing on the interdependence of local and regional markets, with a breath-mediated continental subsidiarity and pluralism identity. Europe has historically been at the forefront of the battle for the defense of biosphere, one more reason to exploit its great potential in a geopolitical vision of the multilateral world destinations.
