The Alarming Science Behind Climate Change’s Increasingly Wild Weather: Ostro And Francis On Video


Earlier this month, Chris Mooney moderated a terrific Climate Desk event featuring top climate researcher Jennifer Francis along with senior Weather Channel meteorologist (and former skeptic) Stu Ostro.

Climate Desk summarizes their findings:

Ostro’s observations suggest that global warming is increasing the atmosphere’s thickness, leading to stronger and more persistent ridges of high pressure, which in turn are a key to temperature, rainfall, and snowfall extremes and topsy-turvy weather patterns like we’ve had in recent years.

Francis’s scientific story is complementary. She sees the rapid warming of the Arctic weakening the northern hemisphere jet stream, and thus, once again, slowing down the weather, leaving a given pattern stuck in place for longer (making any event potentially more disruptive and extreme).

The event is a must-see twin presentation:

As Climate Desk explains:

Stu Ostro is a senior meteorologist at the Weather Channel, and was a longtime climate change skeptic—until the devastating 2005 Atlantic hurricane season, when he started documenting hundreds of cases of extreme and unusual weather and the patterns associated with them, and became convinced that something is very off about the atmosphere.

For more on Ostro’s work and amazing story, see:

Jennifer Francis is “a top climate researcher focused on the Arctic, whose work has drawn dramatic attention in the context of the very warm U.S. winter of 2012 (and attendant droughts and wildfires), the Russian heat wave and Pakistan floods of 2010, and other extreme weather events.”

  1. If you think about it in terms of thermodynamics, more heat is being added to the vessel. Something’s gotta give.

    Burn more fuel in a car, the RPMs increase and it goes faster. Let the pressure cooker sit on the stove too long, the steam builds and it blows its lid. Add heat to the atmosphere, the ice melts, the air takes up more moisture, and the circulation and precipitation pattens change.

    Rather than post problems ad nauseam, why not post some REAL solutions?

  3. mememine69 says:

    Meanwhile, the entire world of SCIENCE, lazy copy and paste news editors and progressivism had allowed bank-funded and corporate-run “CARBON TRADING STOCK MARKETS”(ruled by trustworthy politicians) to trump the UN’s efforts into 3rd world fresh water relief, starvation rescue and 3rd world education for just over 28 years of insane attempts at climate CONTROL.
    Science has never said it will happen, only might happen despite being at the brink of unstoppable warming. Not one single IPCC warning was without “maybes”. Help my planet is on fire maybe? If science just said it will happen, not just might happen or said their crisis was as inevitable as they like to say comet hits are, the debate would end instantly.

    Climate Changed…. We have a situation unfolding here in Calgary

    Here is another must see/hear interview in this vid…

    Canada Calgary Aerial View + Bob Sanford speaks Floods(Climate)

    “climatic conditions are more variable than we thought”

    “we do not have means anymore to protect selves in flood plains”

    Hi Joe,

    mememe…. is a long-time climate troll who contributes nothing useful or worthwhile to discussions. Scientific evidence has even quantified the damage that such trolls do to on-line public discourse.

    As soon as you see this, could you delete the troll-post forthwith?

  7. prokaryotes says:

    Great to see that Stu Ostro was open to accept that he has been wrong in the past. He seems to be a really cool guy too.

  8. Mulga Mumblebrain says:

    Having continued being a denialist until 2005 doesn’t tend to make one assess his understanding of science very highly. Still, better an ex-denialist than a still active one, like 90% plus of the creatures.

    The West Fork fire in Colorado :

    Fire behavior on the West Fork fire was extreme; it made a close to seven-mile run in a northeasterly direction. Eric Norton, fire behavior analyst for the NIMO Team, said, “The fire behavior we saw yesterday was so extreme, it was undocumented and unprecedented.” The fire more than doubled in size going from 12,001 acres to close to 29,000 acres today.

  10. Colorado Bob says:

    The West Fork Complex, including the West Fork, Papoose and Windy Pass fires, is reported at 53,544 acres.

  11. Chris says:

    Wow, that first hour of the video is absolutely riveting. Make sure you watch the entire thing.

    Reality always wins, some people just take longer to lose, ME

  13. colinc says:

    Rage not, Supe’, nature is already ratcheting up the only, “REAL solution.” The melee will be spectacular. ;)

  14. Paul,
    I’ve spent a lot of time in Calgary, walking along the Bow River, eating at the restaurants in the Eau Claire Marketplace and at the River Cafe. The Bow has always been very low when I’ve been there. It’s hard to imagine the flood. Did it reach Fourth Street?

  15. Welcome and good cheer to all who have come to their senses.

  16. prokaryotes says:

    During the talk, Stu mentions the URL for his slides

    Though the slides are 1072 slides as of now (lol) :) Takes a while to load :)

  17. Merrelyn Emery says:

    Indeed, and I anticipate there will be hordes coming aboard pretty soon, ME

  18. Paul Magnus says:

    cant help you there, never been to Calgary.

    The 30 min part with Jennifer Francis

    Arctic Amplification: Jennifer Francis June 6, 2013

  21. Colorado Bob says:

    The straight winds last night reached 90mph in Minn. It was the largest outage in Excell Entergy’s history
    I have thought for years that telephone poles, is the way to measure this new normal. And a way to make lot’s of money.

    The beetles are killing all the trees, and the winds are blowing them down.

    How about we all form an invest trust on Kickstarter ?

  22. Colorado Bob says:

    Most telephone poles in America are over 40 years old.

  23. Colorado Bob says:

    Our side needs money. Period.

  24. Colorado Bob says:

    How about we all form an invest trust on Kickstarter ?

    And we use that , to award a winner that replaces all the 40 year old telephone poles in American ?

  25. Colorado Bob says:

    It has to be cheap, light , strong , and easy to replace.

    That’s our prize.

  26. Colorado Bob says:

    The power into my house comes on poles that are over 50 years old.

  27. Colorado Bob says:

    We make this from that cheap plastic shopping bag , that kills turtles, and lands in my fruit trees.

  28. Colorado Bob says:

    We make this from that cheap plastic shopping bag , that kills turtles, and lands in my fruit trees.

    Buy a gallon of milk , they give you 2 bags of coverage. The sack is engineered to use just one bag. But everyone gets 2 bags. Unless you tell them , “Don’t bag my milk man”. Then you get a 2 inch strip of red tape.

  29. kermit says:

    Yes, scientists have all the evidence and speak with the appropriate level of qualifications; trolls, religious fanatics, and unpaid minions speak with certainty but have no evidence.

  30. I wish their slides were visible – maybe with the speakers in an inset box so we can see things better.

    Excellent video otherwise!
