The Global Context: Major Forces Shaping Our World

Lors de la Conférence des Parties à la Convention-cadre des Nations unies sur les changements climatiques (CCNUCC) qui s'est tenue à Paris en 2015, les gouvernements se sont engagés à limiter l'augmentation de la température mondiale à un niveau bien inférieur à 2°C par rapport aux niveaux préindustriels. Ils se sont également engagés à atteindre, dès que possible, un pic de leurs émissions et à parvenir à la neutralité carbone au cours de la seconde moitié du siècle. Pour autant, m ...

During the 2015 Paris Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), governments pledged to limit the global temperature increase to well below 2°C above pre- industrial levels, to peak emissions as soon as possible, and to achieve carbon neutrality in the second half of the century. Yet, even assuming full implementation of the commitments made by governments in Paris, the global concentration of greenhouse-gas (GHG) emissions will ...

This paper estimates the economic impacts of climate change over the Brazilian regions until the end of the century. We estimate the direct and indirect impact of the projected changes in climate on the yield of the country’s main crops. The results point to a broad spatial heterogeneity of impacts across the country. Using the extreme scenarios created by the Intergovernmental Panel on Climate Change (IPCC) (RCP 2.6 and 8.5), our predictions indicate that the average annual losses ...

For science fiction writers, the universe has no limits. They imagine spacecraft conquering the unknown, the mining of asteroids, access to solar power and room for colonization by earthlings tempted by new frontiers billions of miles and dreams away. Or worlds to conquer barred by radioactive fields, devilish storms, metallic dust, unbearable darkness leading towards black holes and hell in space, and the sun, radiating up to 15 million degrees Celsius, which suggests nothing less ...

In an effort to spur economic growth, industrial parks were created to combine industrial activities with infrastructure, service, and commercial activities. These parks involve a collection of businesses, utilizing a combination of heavy and light manufacturing, that are located in a dedicated zone for industrial use to boost efficiency, minimize operational costs, and maximize output. Though industrial parks can contribute to economic growth and social development in a region, the ...

En multipliant par deux son cours durant les trois premiers mois de l'année 2021, puis en le divisant pratiquement par deux, en quelques jours du mois d'avril 2021, le Bitcoin interroge, nous interroge. Ce Policy Brief lui est consacré, rappelant son histoire qui commence en 2009, en en faisant un enfant de la crise financière de 2008. Il insiste, aussi, sur le recours à la cryptographie dont s'inspire le Bitcoin, utilisant ses supports à travers la Blockchain et le Minage pour sécu ...
