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…

Trump: Record Cold Disproves Global Warming!

CO2 emissions from fossil fuel burning caused the Arctic to warm at least twice as fast as the rest of globe, resulting in the disappearance of Arctic sea ice – which in turn weakens the polar vortex, which in turn favors cold air intrusion into lower latitudes, and vise-versa.

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…

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…

The California drought and climate disruption

ClimateProgress covered the jet stream connection on Monday: It will be unseasonably chilly in the eastern part of the United States this week, due to a peculiar weather pattern that’s causing deep waves in the jet stream. One of those big waves is bringing cool air down from the northeast Pacific and the Arctic. This…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

Jason Box explains the unprecedented Winter 2014 (Northern Hemisphere)

ClimateCrocks: Dr. Jason Box, Chief Scientist of the Dark Snow Project, and a researcher formerly of the Byrd Polar Center at Ohio State, now with the Geological Survey of Denmark and Greenland – has spent the last week in Svalbard, a group of Islands high in the arctic, controlled by Norway. I asked him to chat by…

Dr. Richard Rood on Atmospheric Cycles

ClimateCrocks: Dr. Richard  Rood is a Veteran NASA Atmospheric Scientist, currently teaching at theUniversity of Michigan’s College of Atmopheric, Oceanic, and Space Sciences. Dr. Rood also posts regularly on Dr. Jeff Master’s Weather Underground. I sat down with Dr. Rood not long ago to talk about developments in climate science. This is a small, but significant…

BBC: Wavier Jet Stream ‘May Drive Weather Shift’

BBC: New research suggests that the main system that helps determine the weather over Northern Europe and North America may be changing. The study shows that the so-called jet stream has increasingly taken a longer, meandering path. This has resulted in weather remaining the same for more prolonged periods. The work was presented at the…
