Save The Climate : solutions for the future, action now
HOW TO (REALLY) REDUCE GREENHOUSE GAS (GHG) EMISSIONS

What we want :

unrestricted consumption of fossil fuels is inducing, via GHG emissions, a global climate change whose foreseeable consequences are daunting. Save The Climate (SLC) seeks to bring a neutral, scientific, Cartesian contribution to the debate. SLC considers that a powerful popular movement is urgently needed that, far from ideological stands, would express the real facts and the consequences that they imply.

  •  A James HANSEN Release

     figure 1 hansen

     July 2019 was the hottest month ever in the GISTEMP analysis, i.e., since 1880 when adequate instrumental data became available. July was +0.93°C relative to 1951-1980 or +1.17°C relative to 1880-1920, which is significantly warmer than prior Julys (left figure above). July was the second consecutive month of a monthly record high (right figure).  The real temperature (not anomaly) exceeded that in August 2016, which had been the warmest month.

  • Climate: Recognizing True from False

    Jean Poitou                                                          Translated by Elisabeth Huffer

    Save the Climate

     

    Foreword

    Although the part played by humans in today's global warming is acknowledged virtually unanimously within the climate science community, a number of individuals are relentlessly working to convince the public and decision makers that this is not so. Some of the climate change deniers doubt in good faith that humans can have any influence on the climate. Others voice such opinions to further their own interests:  the actions that need to be undertaken to reduce, or to adapt to, global warming are disadvantageous to them.

    Some of the arguments presented by those whom we call climate warming skeptics or climate warming deniers are grounded on biased data or on data sets that carefully exclude whatever might contradict their line of argumentation. Other arguments rest on calculations that are not realistic because their authors have a simplistic view of the processes at work in the climate system.

  • The New EU Parliament - A Change of Climate?

    The outcome of the European Parliamentary elections shows that climate warming is now at the heart of European considerations. This is good news. Yet, to what extent are we unanimous on the solutions that should be implemented?

    The French Greens along with the associations they are close to (Greenpeace, WWF (World Wide Fund for Nature), FNE (France Nature Environnement a French federation of associations for the protection of nature) and others), the Syndicat des Énergies Renouvelables (federation of renewable energy industries), the public agency ADEME (French Environment & Energy Management Agency) all remark that France is lagging behind Germany in the development of renewable energies. Indeed, Germany produced 3.8 times more wind electricity and 3.9 times more photovoltaic electricity than France in 2018. However, the per capita CO2 emissions of Germany (8.88 metric tons) are twice those of France (4.38 metric tons). This observation alone shows that resorting to nuclear power for electricity generation is much more efficient in terms of CO2 emissions than resorting to intermittent renewables.

  • What Is to Be Done with Nuclear Waste?

     Hervé NIFENECKER                                                Translation by Elisabeth Huffer

    Summary

    France is in a distinctive position. Almost all of the electricity it produces is carbon-free, thanks to its hydroelectricity and nuclear power. The "Sauvons le Climat"  organization endeavors to put forward the pathways that are best adapted and most efficient to further limit carbon dioxide emissions rapidly, thus mitigating the potentially considerable risks associated to uncontrolled climate warming. It is thus duty-bound to be involved in the recently launched debate on the PNGMDR (Plan National de Gestion des Matières et Déchets Radioactifs - National Plan on Management of Radioactive Materials and Waste).

    "Sauvons le Climat" which was involved in the previous debates on radioactive wastes considers it is essential, in such a complex issue, to review basic data so as to enable our fellow citizens to make an informed judgment on the impact of radioactive waste and materials, as compared to the part played by nuclear science and technology in the struggle against climate change, and also in numerous other fields, such as medicine, industry, energy independence, competitiveness.

  • German Electricity and its Negative Prices

     

    In this study, we discuss the results obtained from a thorough analysis of the electricity production prices displayed by Fraunhofer ISE, an "Institut für Solare Energie-systeme" on its internet site www.energy-charts.de. Our analysis whose title is "Negative Electricity Prices in Germany?"[1] is a comprehensive compilation and tight analysis of the Fraunhofer data covering all of 2017. The study also includes tutorial help for the curious reader in his/her navigation of this very rich site, were he/her to perform a personal verification of the exactitude of this study based on indisputable data provided by a German institute dedicated to the promotion of solar photovoltaics and the Energiewende policy.

  • Carbon Neutrality: Yes, but How?

    Carbon neutrality by 2050 is the new, ambitious, objective set by the French Government, instead of the objective that had previously been set, a division by a factor 4 of our CO2 emissions.

    Carbon neutrality is achieved by a country when the amount of CO2 absorbed in this country, either naturally or via human action, entirely compensates the emissions of that country. In its 5th report in 2013-2014, the IPCC anticipated that the global mean surface temperature increase in 2100 could be limited to 2°C provided carbon neutrality at the global scale could be reached before the end of the 21st century. The IPCC SR15 special report published in autumn 2018 stipulates that carbon neutrality will have to be achieved by 2050 if the global temperature increase is to be limited to 1.5 °C.

  • Is the French Government Turning a Deaf Ear to Youth Demanding Climate Warming Action?

     European Youth are rallying against climate warming.

    While the French government has decided to shutdown two operational nuclear reactors, we observe that it is hesitating to shutdown some coal-fired plants. The nuclear reactors are large capacity installations that produce electricity with no CO2 emissions while the coal-fired plants are, on the contrary, the installations that produce electricity with the largest CO2 emissions. Are we really intent on wanting to fight climate warming?

  • Spontaneous balancing of wind power in Western Europe: origin and limits

    1. H. Flocard[1], translated by Jean-Louis BOBIN

    Abstract

                Grounded on data from six Western European countries, the limits of natural balancing from the sum of wind power productions over several thousand-kilometre distances are investigated. We show that data and the associated balancing are satisfactorily reproduced using simple probabilistic laws. Observations and the subsequent analysis show that the hoped for smoothing of wind power production fluctuations does not happen. Consequently, the foreseen implementation of a high voltage network across national borders is not considered as a valuable contribution to overcome the drawbacks of wind power in the management of the national and European grids.

  • Health Impacts of the Different Energy Sources

    Energy in all its forms is an essential element of life in our societies. However, along with the many benefits it provides, every stage of its implementation has negative repercussions.

    At a time when a growing sensitivity is developing to control and reduce the consequences of human activities that are detrimental to the environment, the production and use of energy are subjected to close scrutiny. Similarly, weighing the various sources of energy involved with regard to their impacts on public health proves to be essential.

     

     

  • Translation of  La stratégie bas carbone de la Suède by Jean Fluchère

    France always puts Germany forward as a model but Germany's "Energiewende" is an obvious failure as even France Stratégie[1] recognizes.

    On the contrary, we have a remarkably successful low carbon strategy example with Sweden and its 10 million residents.

    As early as 1991, Sweden embarked upon what we now call a low carbon strategy.

  • SLC meets the challenge of global warming mitigation to 1.5°C

    During the COP21, the signatory countries asked the GIEC to study the possibility of limiting the increase of the Earth surface temperature to 1.5 rather than 2 degrees Celsius, with respect to the pre-industrial period, circa 1850. Associated with its international collaboration spin-off "Global Initiative for Saving Our Climate (GISOC)", SLC met the challenge by proposing the scenario presneted herunder. It is, in this particular case, the translation of the article displayed in the magazine "International Journal of Global Energy Issues", Int. J. Global Energy Issues, Vol. 40, Nos. 3/4, 2017.

    The possibility of reaching the global warming objective of 1.5 degrees Celsius or below rests on the complementarity of a strong development of nuclear power and renewable energy sources as a total replacement for fossil fuels.

     

  • Save the Climate has written to President Donald Trump through Ms Jane
    Hartley, United States Ambassador to France. In its letter, SLC
    expresses its hope that the United States' removal from the Paris
    Agreement will not be detrimental to the planet as a whole. We also
    attract President Donald Trump's attention to the  great advantage that
    renewed major investments in the nuclear sector for electricity
    production would represent both for the climate and for the United
    States' economy, while making use of the expertise that the United
    States have acquired over the years in this field.

    "Electricité éolienne et solaire, émissions de CO2, et prix de l’électricité pour les ménages en Europe de l’Ouest" 

    Summary

    Over the past 15 years, most European countries have been attempting, to a various degree, to increase the share of intermittent renewable electricity sources (iREL) in their electricity mix, mainly with wind and solar photovoltaic (PV).  The official goal is to significantly reduce the CO2 emissions of these countries and also to improve their energy independence.

    The present study of a set of 15 Western European countries that are similar in their sociology, technology and economy shows that this policy breeds poor results...
