The battle for the climate has only just begun – The Figaro

Despite the excitement after the Paris agreement, there are voices including that of Laurent Fabius, to remind you that you need to go much faster and be more ambitious in the fight against climate change.

faster and more ambitious. Now that opens for fifteen days the 22nd conference on the climate in Marrakech, under the aegis of the united nations (COP 22), many are those who call for an acceleration of the movement to fight against climate change. This is the case of a report made public on three November by the experts of the Unep (united Nations program for the environment). This is also the message of Laurent Fabius, now the chairman of the constitutional Council but who was the principal architect of the agreement signed last year, at the same time in Paris, in the framework of the COP 21.

of course, the very large majority of specialists continues to congratulate on the huge success that was the adoption of the Paris agreement by the representatives of more than 190 countries. This text provides in particular that the countries undertake to do everything to maintain the temperature increase below 2°C and, if possible, of 1.5°C. All rejoice, also of the speed with which the agreement has been signed and ratified (respectively 185 signatures and 100 ratifications to date).

But if the agreement is based on major objectives to be achieved (reducing temperature, but also finance, adaptation, support of the poorest countries…), it also relies on the commitments of reduction of greenhouse gas emissions individually by the signatory countries. However, all the calculations tend to show that in adding up these commitments it is far from the account.

This is exactly the purpose of the Unep report. “The world must urgently and radically to revise its ambitions upwards to reduce about a quarter of the global emissions of greenhouse gas emissions expected by 2030 and have a chance to minimize the dangerous climate change,” stresses the report. In a small fifteen years, emissions are expected to reach 54 to 56 gigatonnes ( billion tonnes ) of CO2 equivalent. Gold reminds us of the report, It should not exceed 42 Gigatonnes “to have a chance of limiting global warming to 2°C” . Even in the case of a full implementation of the commitments made in Paris, “projected emissions by 2030 will lead to a rise in global temperatures from 2.9 to 3.4°C by the end of the century”, will continue to ensure the UN experts.

to try To make an idea less abstract consequences related to CO2 emissions, researchers who recently published their findings in the journal Science explained “that for every tonne of carbon dioxide emitted into the atmosphere, the warming that results causes the melting of about 3 m2 of arctic ice”. Gold, a tonne of CO2, it is a flight for one passenger between New York and Europe, or even 4000 km by car precise Dirk Not, climatologist at the Max Planck Institute for meteorology in Hamburg (Germany ), one of the co-authors of the study. For scientists, one of the questions is to know when the arctic sea ice will disappear in summer. This year it reached a low of 4.14 million km2, the second lowest amount since 1979, the year that marks the beginning of satellite observations.

“The Paris agreement is an outstanding achievement but this is not enough,” insists, therefore, Laurent Fabius, in an interview with the Sunday Newspaper. “Compared to pre-industrial times, the overall temperature of the planet in 2015 has already increased by 1°C . By incorporating the commitments made in Paris, it is likely to increase by 1.5°C by 2030 and 2°C by 2050. How, therefore, sent to stay under the 2°C in 2100?” is concerned, t-he . It would have zero net CO2 emissions in 2050 (a balance between what is emitted and what can be absorbed particularly by the oceans and forests). However, the green energy have a nice develop very quickly, 82% of the world’s energy is still produced by fossil fuels.

“Jacques Chirac had said as early as 2002 “our house is burning and we look elsewhere.” Today, I would say, “we don’t look more we act in the wake of the Paris agreement, but our home continues to burn and there red alert” launches the former Prime minister who advocates for developing a “global compact for the environment” that would give more rights, such as the “repair damage”.
