The scientists launch a warning without precedent
About this event: 15th Commission on Sustainable Development


The scientists launch a warning without precedent The scientific community launched Friday a warning without precedent on the extent of the climatic change in moment on the human responsibility in the reheating for planet. `' All converges to show the essential share of the man in the reheating of the climate `', underlined Susan Solomon, president of the scientific working group by presenting the 4th report/ratio of the Intergovernmental Group of experts on the evolution of the climate (Giec)' Never this certainty, acquired with 90%, had not been also strong since creation in 1998 by UNO of this vast network of world expertise. The gases are thus directly blamed for purpose of greenhouse (whose CO2, carbon dioxide, is the principal one) envoys in the atmosphere by the companies énergétivores out of oil, gas and coal since the beginning of the industrial era. `' the reheating is from now on unambiguous: all that moves around us testifies some'', increases the French climatologist Jean Jouzel. Alarm sounded in the capitals which, from Brussels, in London or Berlin, called in an urgent renegotiation of the international agreements, whereas the international community must decide future of the protocol of Kyoto of fight against the effect of greenhouse. `' the day approaches oừ the climatic racing will escape has any control: we are with the threshold of irreversible, also has lance the president. French Jacques Chirac, appealing A a revolution of the consciences in opening of its international conference for an ecological governorship, in the tread of Giec. In Washington, president George Bush, restive upon the multilateral engagements, has judge who the report/ratio will contribute has the whole of knowledge that we have to study the best way of answering the challenges of the climatic change. Fruit of the cross studies several thousands of scientists, the forecast book ends has a prospect for +1,8 A + 4ºc by the end of the century compared to the period 1980-1999, a better estimate among six scenarios consider, of most virtuous with more unslings. These values are thus averages, prudently adopted by consensus between the representatives of the States, which do not exclude the racing up to 6,4 degrees in worst from the cases and perhaps even twice more to the poles. The average temperature of the ground is currently established around 14ºC, 15,54ºC for 2007 according to figures' of the British weather. In addition to the rise of theof the level of the oceans could reach nearly 60 cm, while the experts judge very probable that and episode extreme, heatwave heats of strong precipitations continue to become more frequent. However, 40cm in more on the surface of the oceans, they are 20 million people obliged to flee their place of life, insists Jean jouzel, who points out that the climatic change will not affect the only future generations, but the children who are in nursery school and even in primary education. These disordered states are all the more alarming, insists the report/ratio, which they will remain inescapable during more than one millenium. Does essence is from now on that the conclusions of the scientists are translated into real political debate, insists the climatologist of CNRS Herve the TREUT. How long remain before acting? Three hours! Launch it in the forms of joke. The International Energy Agency (IEA) made the point that at the rate/rhythm of the current policies, the world emissions of gas has effect of greenhouse were still going to increase by 50% from here 2030 and more than to double 2050. But if we act now, this model of nondurable and dangerous development perhaps modifies adds it.
