El cambio climático antropogénico, la destrucción de ecosistemas, la creciente extracción de recursos, y el cénit de los combustibles fósiles, pueden colocar al capitalismo global ante retos nunca vistos en pocas décadas. Las sociedades humanas están capacitadas para pasar de estrategias maximizadoras de potencia a estrategias optimizadoras de efic...

The encountering of the subtropical Brazil Current (BC) and the subantarctic Malvinas Current (MC) along the western margin of the Argentine Basin forms the Brazil-Malvinas Confluence (BMC), one of the most intense open-ocean fronts in the world ocean and a site for the formation of intermediate water masses. Here, we provide a comprehensive descri...

A 100% renewable economy would give a lasting solution to the challenges raised by climate change, energy security, sustainability, and pollution. The conversion of the present transport system appears to be one of the most difficult aspects of such renewable transition. This study reviews the technologies and systems that are being proposed or pro...

Worldwide tank spills represent 10% of the average annual input of oil in the sea. When such spills arise from wrecks at depth, neutralisation of environmental impacts is difficult to achieve. Extracting oil from sunken tankers is expensive, and, unfortunately, all of the oil cannot be extracted, as the Prestige case demonstrates. We propose an env...

We use the concept of Energy Return On energy Invested (EROI) to calculate the amount of the available net energy that can be reasonably expected from World oil liquids during the next decades (till 2040). Our results indicate a decline in the available oil liquids net energy from 2015 to 2040. Such net energy evaluation is used as a starting point...

A feasible way to avoid the risk of energy decline and combat climate change is to build a 100% renewable global energy mix. However, a globally electrified economy cannot grow much above 12 electric terawatts without putting pressure on the limits of finite mineral reserves. Here we analyze whether 12 TW of electricity and 1 TW of biomass (final)...

Article
The peak of fossil fuels is probably a matter of decades rather than centuries. Setting-up a new energy mix, initially based on renewable primary energy and electrification of the economy, seems unavoidable and it may start a last expansive cycle, but it also will deplete an important fraction of reserves of several crucial minerals. Soon after it,...

The model of Paillard and Parrenin (Earth Planet Sci Lett 227(3–4):263–271, 2004) has been recently optimized for the last eight glacial cycles, leading to two different relaxation models with model-data correlations between 0.8 and 0.9 (García-Olivares and Herrero (Clim Dyn 1–25, 2012b)). These two models are here used to predict the effect of an...

Using different statistical slowing-down descriptors, such as variance and lag-1 autocorrelation increase, it has been argued that glacial-interglacial changes in the Earth System result from bifurcations in a continuous system. But a quick variation in the state of a system may also result from a “relaxation oscillation” [3] (Fig. 1b). In this stu...

web site http://www.medeas.eu/ MEDEAS project is an European Project funded by H2020 programme that will design a new energy-economy model for the EU transition to a low carbon emissions energy system. This model will take into account the necessary flexibility to deal with different levels and interests of stakeholders at great sectorial and spatial detail and will be based on the open access programming language (Python). PROJECT DESCRIPTION The transition to a low carbon economy needs to satisfy multiple (often competing) objectives including: socio-economic competitiveness, protection of the environment, creation of quality jobs, and social welfare. Policy-makers and other key stakeholders require more holistic tools which do not just focus on the energy sector, but consider the implications of policies on other domains including the economy, society and the environment. Currently, many tools lack sufficient integration of these important areas despite being tightly connected to the energy sector. Furthermore, current modelling tools often lack sufficient documentation, transparency and have been predominately developed for a specialised audience, which makes validation and comparison of results as well as independent review more challenging. The MEDEAS project aims to solve the current challenges of integration and transparency by developing a leading-edge policy-modeling tool. The MEDEAS model will be based on WoLiM, will consider TIMES and LEAP models and will incorporate Input-Output Analysis, which supports the accounting of environmental, social and economic impacts. Transparency will be achieved through an open access freeware distribution of the model based on the open access programming language (Python), providing a detailed user manual, addressed to a wider non-specialist audience, and including free internet courses and learning materials.
