Notre avenir va se jouer, dans une grande mesure, au sommet de Copenhague sur le climat.
L’impressionnant film «Home», réalisé par Yann Arthus-Bertrand, semble-t-il, aura fait réfléchir tous ceux qui l’ont vu. La prise de conscience est palpable mais c’est dans la quotidienneté de notre vie que nous sommes appelés à jouer pleinement notre rôle.
Nous devons nous mobiliser et faire pression sur nos gouvernements pour que ce rendez-vous majeur, vital, ne soit pas un rendez-vous manqué. Je vous y invite.
Le président américain, Barack Obama, avait initialement prévu d'aller à la conférence le 10 décembre, en récupérant au passage son prix Nobel de la Paix, en Norvège. Cependant, il a changé d’avis et sera dans la capitale danoise le 18 décembre, dernier jour de la conférence. La Maison Blanche met ce changement de plan sur le compte «des progrès réalisés dans le sens d’un accord significatif de Copenhague».
Lors de la conférence de Bali sur le changement climatique, en 2007, les États-Unis s’étaient opposés à plusieurs propositions. A présent, l'offre des États-Unis pour réduire de quelque 17%, les émissions de carbone. La Chine et l'Inde sont invitées à agir dans le même sens.
Ainsi les propositions de compromis de certains pays ont incité d'autres à suivre l’exemple.
Obama assure que les États-Unis sont prêts à s'engager à réduire ses émissions de carbone «dans une fourchette de 17% d'ici 2020». Effet boule de neige, voilà qu’à son tour, la Chine et l'Inde se sont engagées à réduire leur «intensité en carbone», tout en continuant à se développer économiquement. Et l'Union européenne parle d'augmenter sa promesse de réduire les émissions de 20% à 30% d'ici 2020. Le Japon affirme également qu'il peut réduire ses émissions de 25%. Assistons-nous à un sursaut des dirigeants de ce monde, ou simplement l’éveil d’une conscience écologique mondiale…
Mais il ne faut pas être naïfs. S’il y a une volonté écologique, c’est aussi parce que les grandes puissances ont réalisé que la planète s’essouffle et paie le prix de la course au développement.
Certaines nations en développement estiment, pour leur part, qu’elles ne devraient pas avoir à payer pour les péchés des nations déjà industrialisées, comme l’Amérique le symbole de la réussite ou encore l’Angleterre et d’autres pays qui ont bénéficié de la grande révolution industrielle du 19ème siècle. Ces nations estiment qu'elles ont besoin de continuer à faire croître leurs économies pour sortir leur population de la pauvreté.
Ainsi, Copenhague s’annonce déterminant. Espérons un accord dont l’objectif sera la survie de la Terre. L’enjeu est de taille… | |

| Starbright | | | Every breath you take is a prelude to expelling carbon dioxide, which of course proves once again global warming is human caused. Population is out of control, especially in the third world countries, including Mauritius.Another natural cause is that the earth goes through a cycle of climate change and this climate change usually last about 40.000 years.. Man-made causes probably more damages and the major cause is the overpopulation. More people means more food, and more methods of transportation, right?We breathe out CO2 which accelerate global warming.All the trees that convert on CO2 to Oxygen are being demolished because we are using that we cut the trees down for our homes and buildings.The trees are not being replaced, so we are constantly taking advantage of our natural resources and giving nothing back in return. | | | Emiliano Z | | | Give the Earth back to cockroaches; they'll do a better job with it. | | | Mr X | | | ... and temperatures will go up and down then back up then back down and we'll be long gone before the earth really starts caring ! | | | From: GLACIERS | | | From : GLACIERS.
International cooperation remains key for dealing successfully with global environmental challenges.
Copenhague s’annonce déterminant. Espérons un accord dont l’objectif sera la survie de la Terre. L’enjeu est de taille…/ Climate is just one of at least nine critical biophysical parameters that are essential for Earth to maintain its capacity for self-regulation, and for humans to remain within these limits will require the very best international cooperation we can muster. Substantial progress this December will give us a blueprint for dealing with climate and for dealing with each of the other biophysical limits we are going to bump up against in coming decades. Conference in Denmark nurturing positive expectations at a time when policymakers and negotiators should be redoubling their efforts to craft a comprehensive and effective treaty. Scientists are attempting to take a holistic look at planetary systems and how human demands on these systems are putting stress on the entire planet, states an article, titled "A Safe Operating Space for Humanity." The Earth-system processes and associated thresholds which, if crossed, could generate unacceptable environmental change. They found nine processes for which it is necessary to define planetary boundaries: climate change rate of biodiversity loss (terrestrial and marine) interference with the nitrogen and phosphorus cycles stratospheric ozone depletion ocean acidification global freshwater use change in land use chemical pollution and atmospheric aerosol loading. Climate change, rate of biodiversity loss, and human interference with the nitrogen cycle — have already been overstepped with unknown consequences for the environment and human society, warn the scientists. Holocene and Anthropocene: For the past 10,000 years, Earth's environment has remained remarkably stable, with regular temperatures, freshwater availability, and biogeochemical flows fluctuating within narrow ranges. This period, known as the Holocene, has now been replaced by the Anthropocene, during which human activities have become primary sources of global environmental change. A rapidly growing reliance on fossil fuels and industrialized forms of agriculture, human activities have reached a level that could damage the systems that keep Earth in the desirable Holocene state. The result could be irreversible and, in some cases, cause abrupt environmental change, leading to a state less conducive to human development. The danger, of course, is that in our eagerness to grow our economies and exploit Earth's bounty, we will push our planet beyond these thresholds — compromising the life quality of our children and grandchildren. So far we have taken the big payouts, leaving the losses to future generations. The rich countries cannot do it alone, even if they cut their emissions by 80 percent by midcentury. The world would fall short of its target unless the developing countries pitched in. There is no doubt that this is what we are observing in our world today. Concern for the health of the natural world grows daily and we are seeing increasing signs that our over consumption of resources, excessive use of fossil fuels and our system of use and discard is leaving the poor facing further hardship, the vulnerable more easily exploited, species heading for extinction and a world that is facing ecological collapse. It is easy to forget that the earth is not a problem but a source of wonder and joy. Surrounded by the despair and depression that accompanies any reporting on the state of the earth, it is understandable that people feel a sense of foreboding about the future. Direct experience of the natural world is part of embodying celebration into our lives. As part of a long term plan we encourage all to celebrate local beauty, diversity, challenges and connections. This can be done throughout the year so that seasonal changes are celebrated. These experiences could take the form of a nature walk through a local beauty spot with a guide, experiencing the dawn, arranging a visit to see the spectacles of nature in the local area and many other ideas. This is particularly important as we enter 2010, the UN International Year of Biodiversity. We can contribute to protecting other life on earth through celebrating and protecting our local places and by supporting organisations that are striving to protect them. Education that focuses solely on the elements of science and technology cannot offer a framework of moral values to guide the daily decisions of living. We need an education that helps liberate people from enslavement to a way of life that values consumption, convenience, wealth, status and economic growth above all else, an education that begins to give them freedom to make different choices…True education involves a genuine conversion in the way we think and behave. Belief in global climate change is not a matter of faith. The evidence that the planet is undergoing rapid climate change is factual and beyond scientific dispute. In terms of causation, for almost all the world’s atmospheric scientists, the debate about the human contribution to climate change is now over. It is urgent that tackling the greatest challenge facing humanity this century be confronted by all sectors of society. Climate change is not a distant threat. It is a daily reality and the people that are being hit the hardest are the poorest in the world. We have 2020 targets and even 2050 targets, but it's necessary to act now to reduce the vulnerability of the poorest. Put a human face on climate change. Beyond the statistics, there are people living with the effects of climate change already. It's necessary and urgent to get a bold and ambitious treaty in Copenhagen. One Guatemala tourist while on a visit to US said, local communities are very much affected by the climate crisis, but they are also very resilient. But resilience erodes when scarce energy resources "go to meet the demands that come from the elites, either in or out of the country. He urged people to adopt an austerity toward natural resources. He said his morning shower at a New York hotel dumped a surprising amount of water on him. "It was not only incredible, but unfair- reflecting on the irregular availability of potable water in his country. "We need to encourage a social system where to be is more important than to have,"

Small islands in the Pacific are running short of fresh water as sea water have reached the reservoirs. Look at the beaches of Mauritius owners of "campements" 10 metres from the sea used to proudly brag how easy it is to go to the sea today , the sea comes to them. no further comments, I'm thinking of my grand children. | | | Burn-it | | | Hassan is totaly right.
