World Weather Extremes

Consists of a worldwide map of weather extremes and a separate map for the U.S. and Canada, with comments on the reliability of the records shown. Included are highest and lowest temperatures, greatest snowfalls, highest wind speeds, high dew point, and much more. Records are taken from official sources, and all are documented. 2 maps.

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.

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.

Author Tom Streissguth provides an enthralling look into extreme weather. He examines issues from a variety of expert perspectives, highlighting key future challenges, and addressing the pros and cons of potential solutions. Readers will explore the relationship between global climate change and extreme weather, including air and water chemistry, solar radiation, hurricanes, and tropical cyclones, and heat waves. They will learn about other potential future warming and drought. They will examine the experience and impact from the Dust Bowl of the 1930s to the current water crisis in California.
