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…

Global Warming Speed Bump? The Answer May Be Blowing in the Wind!

By Michael E. Mann via HuffingtonPost: An interesting new paper by Matthew England and colleagues just published in the journal Nature Climate Change tosses another hat in the ring when it comes to explanations of the so-called “hiatus” or “pause” (I prefer “speed bump”) in global warming. As I have discussed previously, the fact that global surface temperatures have not increased…

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…

UK Floods 2014 Could Last for Months + 1.6M Homes at Risk for Flooding

Andy McKenzie, a groundwater scientist at the British Geological Survey, told Sky News that even if the rain stopped today, so much water is soaking through the soil that levels are likely to keep rising for another two months. The risk of flooding could remain high until May, he said. According to the data from the…

UK Flooding and the Science of Climate Change

Climate change is the ultimate challenge but as a matter of fact most governments and the media are still sleepwalking and are in denial for the most part. In the video below “Influence of Arctic sea ice on European summer precipitation (2013)”, Dr James Screen explains the impacts of climate change on farming  and flooding.…

If There’s Global Warming … Why Is It So Cold?

It’s that time of year, the perennial “It’s snowing so it can’t be warming” season – or, as scientists call it, “winter”. Depends on where you’re standing, actually — I stood on a frozen lake with Dr. Jeff Masters to discuss the current planetary changes, but at the same time, in Alaska, historic warm temperatures…

NASA’s AIRS Sees Polar Vortex Behind U.S. Big Chill


Published January 2014: The chilling weather phenomenon that hit much of the U.S. in January is explained by scientist Eric Fetzer using data from NASA’s AIRS instrument.

Climate Matters: Weather Systems Stalling


“It seems like the weather, increasingly, is getting stuck.” Meteorologist Paul Douglas explains this weather pattern that seems to be stuck in a rut. Swells, drought and a polar vortex! Learn how it is impacting everywhere from Hawaii/Alaska all the way to Europe. The Winter Olympics may feel more like the Summer Olympics!

White House: The Polar Vortex Explained in 2 Minutes

by Becky Fried | January 08, 2014  | Release URL Here at the White House, while we’re beginning to thaw from this week’s bone-chilling deep freeze, our discussions about the science of weather extremes are heating up. We know that no single weather episode proves or disproves climate change. Climate refers to the patterns observed in the weather…

Yale: Climate, Jetstream and Polar Vortex


Blanket 24/7 media coverage of the short but frigid ‘Polar Vortex’ temperatures — climate change? global warming? — provides a cornucopia of material for this month’s ‘This is Not Cool’ video.

The Science of the Polar Vortex and Jet Stream

At least since around 2001 we have study papers connecting the polar vortex / jet stream behavior to anomalies, such as cold weather outbreaks or precipitation changes. The polar vortex phenomenon was described as early as 1853. In recent years studies linked changes in the cryosphere to the polar vortex. Feel free to suggest further study papers in the comments.…

Polar Vortex, Jet Stream and Climate Change

Current coverage of polar vortex intrusion. ‘Polar vortex’ could send wind chill to 65 below zero in Midwest More realtime coverage Carson Walker: Temperature records will likely be broken during the short, yet forceful deep freeze that will begin in many places on Sunday and extend into early next week. That’s thanks to a perfect…

US Midwest – Jet Stream delivers Dangerous Flash Floods – “A Water World” (August 2013)

August 8 2013: Mangled Jet Stream Delivers Four Months Worth of Rain in One Week to Missouri; Central, Eastern US to Remain Under Severe Flood Threat ABC News last night, in the below video, aptly described the hardest-hit areas as turning into ‘a water world.’ The coverage shows storm shocked residents staring in awe at…
