Hurricane Florence Stalling connected to Jet Stream

Amy Goodman from Democracy Now interviews Mike Mann on Hurricane Florence, and the connection to climate change. How the weaker jet stream comes in. My colleagues have shown the weakening over the past decades here in Science https://twitter.com/rahmstorf/status/1039618555128557569 Watch the full interview https://www.youtube.com/watch?v=9OuVTEfBatY

Experts Discuss Recent Heat Waves and Atmospheric Changes

The impacts of global warming are now ‘playing out in real-time’. Mike Mann (Penn State), Jennifer Francis (Rutgers), and Noah Diffenbaugh (Stanford), discuss the recent heat waves around the globe, and how it connects with the jet stream pattern, moderated by Markeya Thomas of Climate Signals.

Jet Stream Stalled over Sweden Climate Weather Connection Explained

This heatwave across much of the northern hemisphere could continue for weeks, and possibly even months. And accelerated warming in the Arctic compared to the rest of the planet could be a key contributor. https://www.newscientist.com/article/2174889-warming-arctic-could-be-behind-heatwave-sweeping-northern-hemisphere/ Jennifer Francis (Rutgers University), speaks March 2018 about weather changes. And how are those related to climate change? Full talk…

The New Record Low Arctic Sea Ice and Our Weather

Arctic sea ice decline has long been projected to occur. 2018 and 2017 are the two lowest winter time Arctic sea ice records observed. Disappearing sea ice and moisture transport into the Arctic are believed to cause something called Arctic amplification, which in turn has been linked to two effects (weaker westerly winds, and intensified…

Scientist Reveals 7% More Water Vapor Fuels Storms Today

Jennifer Francis, Ph.D., Research Professor I, Department of Marine and Coastal Sciences, Rutgers University, speaks about extreme weather changes. And how are those related to climate change? In this presentation, Dr. Francis will explain new research that links increasing extreme weather events with the rapidly warming and melting Arctic during recent decades. Evidence suggests that…

Francis: A Trigger for Rapid Arctic Warming

Jennifer Francis from Rutgers University speaks about our atmosphere with a scope on the Arctic response to climate change and the connection to weather. This video is part of a panel presentation published by Earth Institute November 2017, with already improved sound quality (reduced humming sound).

Vanishing Arctic Ice and Amplification

While heat waves and more intense storms have been directly linked to a warming Earth, new research is exploring possible impacts of an Arctic that is warming at twice the pace of the rise in global temperatures. Jennifer Francis, Rutgers University, discusses new research and efforts to understand this controversial aspect of climate change in…

AGU 2015: Jennifer Francis recent studies on Weather Blocking Patterns

Recent Changes in Blocking Characteristics Assessed Using Self-Organizing Maps Speaker: Jennifer Ann Francis Blocking anticyclones are known to be associated with persistent weather patterns that often lead to extreme weather events. An outstanding question, however, is whether the frequency and/or intensity of these dynamical features are changing in response to human-caused climate change, and in…

Why is the Weather in the Northern Hemisphere so unusual mild? #JetStream #ElNino #PolarVortex

Here we look at the current weather configuration in the Northern Hemisphere, with the scope on the mild 2015 winter weather in what seems to affect many regions in northern latitudes this winter. The atmosphere in many northern regions like Canada (Northern America) or Europe is currently dominated by westerly jet stream winds. This configuration has…
