Arctic Amplification Connections to Extreme Weather Events – Complexities Abound: 2 of 2

Paul Beckwith

One of the obvious consequences of abrupt climate system change is the large increase we have experienced in the frequency, severity, and duration of extreme weather events. In addition, these events are happening in regions where they did not happen before, for example, we have had large, previously unheard of snowfalls in some of the driest deserts in the world.

The top down, elevator pitch that I have used for many years is based on the fundamental physics of why the Jet Stream exists in the first place, which is due to the cold Arctic – warmer lower latitudes temperature difference creating a pressure difference driving the high altitude winds (jet streams) along with the Coriolis force effects deflecting winds to the right in the Northern Hemisphere. As the Arctic warms at much greater rates than lower latitudes, the lower temperature gradient (thus pressure gradient) means the jet streams must slow, and thus they become much wavier in the North-South direction. Under the ridges of the Jet stream waves (Rossby Waves) there is high pressure and heat that has moved northward, while in the troughs of the waves cold dry air spills southward. If the wave locations are persistent (blocked) we can get long duration anomalously hot conditions under the ridges, and long duration storms, torrential rainfall, and flooding in the troughs.

This explains why the tremendously rapid Arctic warming is leading to increases in the frequency, severity, and duration of extreme weather events, from a top-down viewpoint.

Bottom-up is more difficult, and the devil is always in the details. In the latter section of my Part 1 video, and in all of my Part 2 video, I discuss a new peer reviewed scientific paper called “How do intermittency and simultaneous processes obfuscate the Arctic influence on midlatitude winter extreme weather events?”.

Since extreme weather events are presently affecting billions of people around the planet, getting at the details is vitally important, in fact it was mentioned that there were 146 recent papers looking into the details of these connections. There is a lot of complexity and confusion, and the connections vary critically depending on the season, for example late fall/early winter the lack of Arctic sea ice in the Barent-Kara Sea, the Chuckhi-Beaufort Sea, and Baffin Bay have been connected to extreme winter cold and snowfall in Eurasia, extreme weather conditions in North America, etc… In late winter, the Stratospheric Polar Vortex often radically undergoes Sudden Stratospheric Warming, leading to large outbreaks of cold Arctic air infiltrating into much lower latitudes in North America and Eurasia.

Clearly, we still have a lot to learn, but it seems impossible to me that rapid Arctic changes can occur without having profound effects on lower latitude weather extremes. I think these connections will become more obvious and resolved as we get closer and closer to complete loss of Arctic sea ice within the next few years.

In Kenya, pregnant women are among those who have been greatly impacted by the COVID-19 pandemic. A recent health ministry report suggests that a section of pregnant women, afraid of contracting COVID-19 in hospitals or unable to access health facilities due to movement restrictions, opted to deliver their babies at home. The government has rolled out measures to ensure pregnant women deliver in health facilities where complications can be tackled should they arise. CGTN’s Wilkister Nyabwa reports.

How climate change affects Florida

CGTN America

Published on Apr 18, 2021

Florida could be considered ‘ground zero’ for climate change ​in the United States.

With its 2,000 kilometers of coastline, rising sea levels are an existential threat to the state.

Flooding in low-lying areas like Miami is already a problem, and that’s spurring a new trend in real estate development that often at the expense of lower-income residents. It’s called ‘climate gentrification.’

CGTN’s Nitza Soledad Perez reports.

The Overview Effect: Space Exploration and Human Evolution: Frank White

Discusses the psychological effect of space exploration, examines the impact of living in space, and shares the personal observations of cosmonauts and astronauts

The Overview Effect: Space Exploration and Human Evolution, Second Edition (Library of Flight): Frank White

Using interviews with and writings by 29 astronauts and cosmonauts, Frank White shows how experiences such as circling the Earth every 90 minutes and viewing it from the moon have profoundly affected our space travelers’ perceptions of themselves, their world, and the future. He shows how the rest of us, who have participated imaginatively in these great adventures, have also been affected psychologically by them. He provides a powerful rationale for space exploration and settlement, describing them as the inevitable next steps in the evolution of human society and human consciousness, as the activities most likely to bring a new perspective to the problems of life on Earth.

White goes on to consider the possible consequences of a human presence in space, both for the pioneers who settle there and for those who remain on Earth. He imagines how having a permanent perspective from outer space will affect our politics, our religion, our social relations, our psychology, our economics, and our hard sciences. He confronts the possibility of rebellion by a space colony and of contact with extraterrestrial beings. And, finally, he makes it clear that our fate is in our own hands, that we will shape our future in space effectively only by fashioning a new human space program, free of excessive nationalism and dedicated to the peaceful exploration of the space frontier.

About the Author

Frank White is a senior associate of the Space Studies Institute in Princeton, New Jersey. He testified before the National Commission on Space and assisted in writing its report.

Midday Science Cafe- Adapting to Change: The Future of California’s Water- E nergy Nexus

Berkeley Lab – Apr 17, 2021

Water and energy, two intricately connected systems, are critical to California’s future as we face increasing urbanization and climate change. In this Midday Science Cafe, we’ll hear from two researchers studying the connection between water and energy, or the “water-energy nexus”. We’ll learn from Julia Szinai about the implications of climate change and climate change solutions on the water-energy nexus and how California’s water and electricity resources may be impacted by the end of the century. Dr. Jennifer Stokes-Draut will illustrate how energy is used in California’s water systems and describe energy-efficient innovations for the future.
