This is, for my money, the best single-source primer on the state of climate change. (New York Magazine) The essential primer on what will be the defining issue of our time, CLIMATE CHANGE: What Everyone Needs to KnowRG is a clear-eyed overview of the science, conflicts, and implications of our warming planet. Questions about climate change addressed in this guide include: DT How will climate change affect day-to-day life in the coming decades? DT What are the implications of owning coastal property in the age of climate change? DT Is retirement to South Florida (or the U.S. Southwest, or even Southern Europe) safe? DT What are the implications of the United States´ withdrawal from the Paris climate treaty? DT What does Donald Trump´s presidency mean for climate action in the United States and around the globe? DT Are efforts to combat climate change making a difference? As the global response to climate change continues to evolve, CLIMATE CHANGE: What Eve
Grasslands are extremely important for forage, biodiversity, and ecosystem services across the globe. Climate change is affecting this biome in ways we are only starting to understand, and this book documents the current state of knowledge, drawing on research from an international team of grassland ecology experts.
In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the signi¿cant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.
A narrative of Indigenous wisdom that provides a road map for the spirit and a compass of compassion for humanity Drawing from ancestral knowledge, as well as her experience as an attorney and activist, Sherri Mitchell addresses some of the most crucial issues of our day, such as environmental protection and human rights. Sharing the gifts she has received from elders around the world, Mitchell urges us to decolonize our language and our stories. For those seeking change, this book offers a set of cultural values that will preserve our collective survival for future generations.
´´Agriculture is rightly blamed as a major culprit of our climate crisis. But in this groundbreaking new book, Eric Toensmeier argues that agriculture--specifically, the subset of practices known as ´´carbon farming´´--can, and should be, a linchpin of a global climate solutions platform´´--
By 1979, we knew all that we know now about the science of climate change - what was happening, why it was happening, and how to stop it. Over the next ten years, we had the very real opportunity to stop it. We failed.
This book presents photocatalysis as a state-of-art technology in energy production and conversion. The ever increasing demand for energy with growing economies has led to a dearth of energy sources. The exhaustive dependability on non-renewable resources of energy has not just depleted them but also lead to the birth of secondary problems such as pollution and climate change. The photoactive processes have opened a new window for the production of green energy and helped in environmental sustainability. The harnessing of renewable sources especially sun and water for fuel production and noxious gases reduction solve both the issues of pollution mitigation and energy crisis.
