Climate Impacts On Extreme Weather

As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.

Climate Change and Extreme Events uses a multidisciplinary approach to discuss the relationship between climate change-related weather extremes and their impact on human lives. Topics discussed are grouped into four major sections: weather parameters, hydrological responses, mitigation and adaptation, and governance and policies, with each addressed with regard to past, present and future perspectives. Sections give an overview of weather parameters and hydrological responses, presenting current knowledge and a future outlook on air and stream temperatures, precipitation, storms and hurricanes, flooding, and ecosystem responses to these extremes. Other sections cover extreme weather events and discuss the role of the state in policymaking. This book provides a valuable interdisciplinary resource to climate scientists and meteorologists, environmental researchers, and social scientists interested in extreme weather. Provides an integrated interdisciplinary approach to how climate change impacts the hydrological system Addresses significant knowledge gaps in our understanding of climate change and extreme events Discusses the societal impacts of climate change-related weather extremes, including multilevel governance and adaptation policy

Long before the "germ theory" of disease was described, late in the nineteenth century, humans knew that climatic conditions influence the appearance and spread of epidemic diseases. Ancient notions about the effects of weather and climate on disease remain embedded in our collective consciousness-through expressions such as "cold" for rhinovirus infections; "malaria," derived from the Latin for "bad air;" and the common complaint of feeling "under the weather." Today, evidence is mounting that earth's climate is changing at a faster rate than previously appreciated, leading researchers to view the longstanding relationships between climate and disease with new urgency and from a global perspective. On December 4 and 5, 2007, the Forum on Microbial Threats hosted a public workshop in Washington, DC to consider the possible infectious disease impacts of global climate change and extreme weather events on human, animal, and plant health, as well as their expected implications for global and national security.

From leading climate scientist Dr. Friederike Otto, this gripping book reveals the revolutionary science that definitively links extreme weather events—including deadly heat waves, forest fires, floods, and hurricanes—to climate change. “Meet the forensic scientists of climate change; if you like CSI, you’ll be equally enthralled with the skill and speed these folks exhibit. But the stakes are infinitely higher!” —Bill McKibben, author of Falter and The End of Nature Tied with Hurricane Katrina as the costliest cyclone on record, Hurricane Harvey caused catastrophic flooding and over a hundred deaths in 2017. Angry Weather tells the compelling, day-by-day story of the World Weather Attribution unit—a team of scientists that studies extreme weather events while they’re happening—and their race to track the connection between the hurricane and climate change. As the hurricane unfolds, Otto reveals how attribution science works in real time, and determines that Harvey’s terrifying floods were three times more likely to occur due to human-induced climate change. At the forefront of cutting-edge climate science, Friederike Otto uncovers how the new ability to determine climate change’s role in extreme weather events can dramatically transform how we view the climate crisis: from how it will affect those of us who are most vulnerable, to the corporations and governments that may find themselves held accountable in the courts. The research laid out in Angry Weather will have profound impacts, both today and for the future of humankind. Published in Partnership with the David Suzuki Institute.

With contributions from experts across the globe, the book utilizes methods, case studies, modeling, and analysis to present valuable, up-to-date knowledge about the interaction of climate change, weather and the many implications of the changing environment. Offers comprehensive, up-to-date coverage of climate research related to extremes Includes both regional and global case studies for applying research to practice, providing a deeper understanding of the science Presents both observed and projected findings using primary research and models

This book provides an authoritative insight on the Loss and Damage discourse by highlighting state-of-the-art research and policy linked to this discourse and articulating its multiple concepts, principles and methods. Written by leading researchers and practitioners, it identifies practical and evidence-based policy options to inform the discourse and climate negotiations. With climate-related risks on the rise and impacts being felt around the globe has come the recognition that climate mitigation and adaptation may not be enough to manage the effects from anthropogenic climate change. This recognition led to the creation of the Warsaw International Mechanism on Loss and Damage in 2013, a climate policy mechanism dedicated to dealing with climate-related effects in highly vulnerable countries that face severe constraints and limits to adaptation. Endorsed in 2015 by the Paris Agreement and effectively considered a third pillar of international climate policy, debate and research on Loss and Damage continues to gain enormous traction. Yet, concepts, methods and tools as well as directions for policy and implementation have remained contested and vague. Suitable for researchers, policy-advisors, practitioners and the interested public, the book furthermore: • discusses the political, legal, economic and institutional dimensions of the issue• highlights normative questions central to the discourse • provides a focus on climate risks and climate risk management. • presents salient case studies from around the world.

This edited book assesses the impacts of various extreme weather events on human health and development from a global perspective, and includes several case studies in various geographical regions around the globe. Covering all continents, it describes the impact of extreme weather conditions such as flash floods, heatwaves, cold waves, droughts, forest fires, strong winds and storms in both developing and developed countries. The contributing authors also investigate the spread of diseases and the risk to food security caused by drought and flooding. Further, the book discusses the economic damage resulting from natural disasters including hurricanes. It has been estimated that in 2017 natural disasters and climate change resulted in economic losses of 309 billion US dollars. Scientists also predict that if nothing is done to curb the effects of climate change, in Europe the death toll due to weather disasters could rise 50-fold by the end of the 21st century, with extreme heat alone causing more than 150,000 deaths a year, as the report on global warming of 1.5°C warns that China, Russia and Canada’s current climate policies would steer the world above a catastrophic 5°C of warming by the end of 2100. As such, the book highlights how the wellbeing of different populations is threatened by extreme events now and in the foreseeable future.

Climate Change: Evidence and Causes is a jointly produced publication of The US National Academy of Sciences and The Royal Society. Written by a UK-US team of leading climate scientists and reviewed by climate scientists and others, the publication is intended as a brief, readable reference document for decision makers, policy makers, educators, and other individuals seeking authoritative information on the some of the questions that continue to be asked. Climate Change makes clear what is well-established and where understanding is still developing. It echoes and builds upon the long history of climate-related work from both national academies, as well as on the newest climate-change assessment from the United Nations' Intergovernmental Panel on Climate Change. It touches on current areas of active debate and ongoing research, such as the link between ocean heat content and the rate of warming.
