 As you know, since the beginning of the 80s, the science has demonstrated that the human activities, what we call anthropogenicism, have led to unprecedented concentration of emission into atmosphere, and in particular six gases, but in particular the CO2, the dioxide of carbon, and the matter. And therefore it has been proven that these emissions are at the origin of what we are witnessing, major climate extreme events, drought, floodings, rays of sea level, and so on and so forth. So therefore in the 80s, the international community has agreed that time has come to join forces in order to stabilize the emission of CO2, in order to limit the growth of temperature on the atmosphere. And they have adopted, in Rio in 1992, a framework convention based on the fact that those who have emitted the most, mainly at that time, the developed countries, the industrialist countries, should take the lead and reduce their emission. The other, if they can, and if they receive money and technology, transfer of technologies, they can have. But it was not mandatory. But meanwhile, since 1992, the world has changed and the science has confirmed that if we don't do nothing, the rays of the temperature may lead to more than five degrees, which will have tremendous impact on the capacity of the planet to continue our sustaining life. So therefore, in Copenhagen in 2009, the international community started to attempt to adopt an agreement with the participation of all, and especially the new emitter of CO2 and greenhouse gases. It was not possible. Two years after, in Durban, an agreement has been reached that, yes, we have to do it and we have to limit the growth of temperature to no more than two degrees. And these imply the participation of all. So in 2011, a committee has been established to prepare a legally binding document with universal participation. No one left behind with the view of limiting the growth of temperature of no more than two degrees. And they have agreed that this should be done in December 2015, and meanwhile Paris, France, has hosted. So therefore it was agreed that by 2015, in December, the world will adopt a new universal agreement with the participation of all, with the view of limiting the rays of temperature to no more than two degrees. And two cultures have been appointed at the beginning, Norway and India, they changed with Germany and Trinidad. And Dan and I had the immense privilege to be appointed in December. So therefore, to lead the process when the plan, the Boeing or the Airbus was landing, was about to land in Burge, where the conference will be held in December.
