This report briefly summarises the status and outlook for hydrogen in each G7 member, including analyses of technology, costs, strategy and stated policy support for each country, and presents recommendations for accelerating global hydrogen trade.
Pandemics, massive earthquakes, war, and other catastrophes inspire immediate action because their casualties and destruction are immediately visible. Climate change is an unyielding problem because its long-range dangers are hidden, and thus it is a global risk unlike anything in human experience The federal government recently announced aggressive climate targets for Canada. We have committed to producing net-zero greenhouse gas emissions by 2050, which will require major changes for our economy and way of life. Canadian citizens need to understand why our most distinguished climate scientists and our senior political leaders think that we must meet this target. Canada and Climate Change explains the importance of policies that will ensure we meet the net-zero emissions target. William Leiss provides a firm grasp on what climate change is and how scientists have described shifts in the earth’s climate as they have occurred over hundreds of millions of years and as they are likely to occur in the near future, especially by the end of this century. Leiss argues that citizens have a right to place their trust in what climate scientists tell us. Canada and Climate Change is an essential primer on where we stand on the issue of climate change in Canada and what will unfold in the years ahead.Mostra libro
Not long ago, the Solar System was the only example of a planetary system—a star and the bodies orbiting it—that we knew. Now, we know thousands of planetary systems, and have even been able to observe planetary systems at the moment of their birth. This Very Short Introduction explores this new frontier, incorporating the latest research. The book takes the listener on a journey through the grand sweep of time, from the moment galaxies begin to form after the Big Bang to trillions of years in the future when the Universe will be a dilute soup of dim galaxies populated mostly by red dwarf stars. Throughout, Raymond T. Pierrehumbert introduces the latest insights gained from a new generation of telescopes that catch planetary systems at the moment of formation, and to the theoretical advances that attempt to make sense of these observations. He explains how the elements that make up life and the planets on which life can live are forged in the interiors of dying stars, and make their way into rocky planets. He also explores the vast array of newly discovered planets orbiting stars other than our own, and explains the factors that determine their climates. Finally, he reveals what determines how long planetary systems can live, and what happens in their end-times.Mostra libro
The universe is vast, filled with mysteries that challenge our understanding of reality. Among these, dark matter stands out as one of the most elusive and significant components of the cosmos. It is an invisible force that cannot be seen directly, yet it exerts a profound influence on the structure and behavior of galaxies, stars, and the universe as a whole. This chapter delves into the concept of dark matter, exploring its nature, how it was first theorized, and why it remains one of the most intriguing puzzles in modern physics and astronomy. Dark matter was first proposed as a solution to an anomaly in the way galaxies rotate. In the 1930s, astronomer Fritz Zwicky observed that galaxies in the Coma Cluster were moving much faster than expected, based on the visible matter in those galaxies. He suggested the existence of an unseen mass, which he called "dark matter," to account for the gravitational pull that would explain these high speeds. This groundbreaking idea, however, was met with skepticism at the time. Over the decades that followed, evidence continued to accumulate, pointing to the presence of dark matter in the universe. Dark matter is not something we can detect with traditional instruments because it does not emit, absorb, or reflect light. It is essentially invisible to electromagnetic radiation, which makes it very different from the ordinary matter that makes up stars, planets, and everything we can see in the universe. Despite its invisibility, dark matter’s presence is inferred through its gravitational effects on visible matter. For example, when we observe the rotation of galaxies, the stars at the outer edges are moving faster than they should, based on the amount of visible matter in the galaxy. This suggests that there is additional mass, unseen but detectable through its gravitational pull, holding these galaxies together.Mostra libro

The speed of technological development, from cell phones to artificial intelligence, opens up exciting new opportunities for promoting human flourishing. It also raises grave risks, threatening not only personal privacy and dignity but also our collective survival. Technologies of Human Rights Representation brings together three fields of research critical to securing our future: changing technologies, human rights, and representation. For each of these fields, this book asks key questions: How can we open the black box of technological advances so that we can more fully understand their effects upon our lives? What can we do to make sure that these effects align with the values of human rights? And how does the way we talk about technology and rights—from military reports and corporate marketing to human rights reports and poetry—amplify or diminish our capacity both to understand and to control what happens next? Contributors from anthropology, communications, criminology, global studies, law, literary and cultural studies, and women and gender studies bring diverse methodological approaches to these crucial questions.Mostra libro
Henri Bergson’s highly influential book, ‘Creative Evolution’ (‘Evolution Creatrice’, 1907) established a theory of evolution - called ‘Creative Evolution Theory’ - which gained a considerable following in the first half of the 20th Century. It also helped the author to win the Nobel Prize in 1927 for his work investigating the origins of biological information and divergence in the evolutionary process. In this work, Bergson seeks an alternative explanation as to how new forms of life emerge compared to those prevailing at the time. This included both the ‘mechanistic’ or deterministic explanations of biological science on the one hand, and on the other the ‘finalist’ or strictly teleological explanation of those who believed in the hand of a ‘Creator’ or God, coordinating life in a divine plan. Creative Evolution proposes a third explanation in what Bergson calls élan vital’ or ‘vital impetus’, a force that infuses all matter and drives it forward into an ever-changing and infinite variety of living forms. This appears as a vital impetus that can also be related to humanity’s own creative life force. Bergson’s book builds on his ‘Theory of Time’ as set forth in works such as ‘Matter and Memory’ and ‘Time and Free Will’. In these works, and in the present volume, Bergson sees continuous ‘duration’ as real time, as opposed to the way in which time is divided up into measured units by the ‘organising’ mind of science. Life, as we really experience it, is subject to constant change and our tendency to explain evolutionary change by looking only at ‘ends’ achieved rather than the processes by which they emerge, divorces us from the life force itself. Instead, Bergson feels we need to reengage with our instincts as well as with our intelligence in order to understand the evolutionary process, as both co-exist to some extent within us, all forms of life having a common origin in that instinctual, innate knowledge of simpler life forms. Though these may be unconscious or semi-conscious, they are, in Bergson’s view, much more in touch with the ever-changing nature of real time than the analytical and rational knowledge of our species As he writes: “Our thought, in its purely logical form, is incapable of presenting the true nature of life, the full meaning of the evolutionary movement. Created by life, in definite circumstances, to act on definite things, how can it embrace life, of which it is only an emanation or an aspect?” It is to attempt an answer to this question that ‘Creative Evolution’ directs its attention.Mostra libro
