The pledges to reduce polluting gases proposed by 147 countries for the global agreement to combat climate change, which would be adopted at the Paris Climate Summit, will mean an increase in planetary temperature of 2.7 degrees Celsius, a higher figure at the 2 degrees set by science.
This was stated this Wednesday by the secretary of the United Nations Convention on Climate Change (UNFCCC), Christiana Figueres, who is preparing the publication of the report that gives an account of the implications of the promises presented by the countries.
When the future Paris agreement begins to apply from 2020, there will have to be a reduction in emissions of four gigatons annually, as calculated by the UNFCCC. Assuming that countries do not raise their current climate goals before that year, which cover until 2030, and that the four gigatons remain until the end of the century, "the planet's temperature will be 2.7 degrees higher than that of the pre-industrial era in 2100 "said Figueres.
But the Secretary of the Convention assured that it is not enough. Science calls for keeping the planet below two degrees so that the impacts of climate change are not catastrophic. However, the official highlighted the "quantity and rigor" of the reduction commitments received: 147 to date proposed by the UN (October 1), and 155 today, in which all industrialized countries and more are located. than 100 from developing countries.
The commitments cover countries that account for more than 90 percent of global emissions, "and without them we would have headed for a temperature increase of four or five degrees, compared to pre-industrial levels," he said.
Is Paris the last hope to save the climate?
At the Paris Climate Summit, to be held in December, the objective will be "to reach an agreement that allows us to build a successful path that takes us below two degrees with future commitments," he remarked. For this reason, in the agreement it will be important to "build a mechanism for review and continuous improvement", as well as "a strong financial and technological support package so that developing countries can grow without a carbon footprint."
Figueres recalled that "it will be the last opportunity to forge an emissions reduction path that allows adaptation to the impacts of climate change at a manageable cost."
In order to give political impetus to the Paris Summit, the Secretary announced that both the President of the United States, Barak Obama, as well as those of China and India will attend the opening of the meeting on November 30.
