Volcanoes: A Forge for Climate Change | Peter Ward | TEDxWilmington

Dr. Peter Langdon Ward worked 27 years as a geophysicist with the United States Geological Survey, being featured on Good Morning America and winning two national awards for explaining science to non-scientists. Nine years ago, while in retirement, he found reliable data suggesting that volcanic eruptions not only cool the earth for a few years, something that is well known, but also can warm the earth substantially. How could this be? Realizing the importance of figuring this out, he set off on a full-time quest trying to understand in detail how volcanism has controlled climate throughout Earth history, throughout the evolution of our species, throughout written history, and why 2015 is the hottest year on record.

Great talk.
The comparison of Pinatubo [causing cooling] and Bardarbunga [causing warming] is a great insight.
It's the 2nd time I see convincing arguments about the warming effects Bardarbunga [the heating of N. Pacific in 2015 was abnormal] but, the connection with the higher solar activity of the 2nd maximum of cycle#24 is not mentioned. This is were the majority of climate studies fail, they don't connect the dots with solar activity properly.
Another point that he missed, in my opinion, is the large amount of SO2 that Bardarbunga emitted, I mean, why it didn't cause cooling. I guess he concentrated in the main points for a few minutes talk.

Wow!! This changes everything! Great talk and very easy to understand. I’d love to see this guy on Joe Rogan ♥️

[mycoffeemyday]

Three cheers for volcanoes! Noticing that politicians never speak about especially the ones currently active!

[BrokenOwen]

Anybody know where the unedited version is? This had 4 or 5 cuts in it and I'm wondering why.

I had heard that CFC's do not interact with ozone in nature because CFC's sink and Ozone foats above normal air. I also heard that DuPont made the "discovery" about CFC's just before their patent ran out and now we are using a different refrigerant that Du Pont has also patented.

[paulmarshall]

wOW. Makes sense! Thank you Dr. Langdon Ward!

Ozone is created by lightning, zero warming potential

Our planet will continue until the Sun dies out.

[ursaltydog]

So could our extreme warming and fires be explained from a drop in explosive but increase in effusive volcanoes?

[jamesprouty]

Global warming and cooling is a complex combination of many factors, and is cyclical. Especially with orbit around the sun. This one factor creates the cycle. All other factors accelerate one or the other, warm or cool.

And now hunga tonga severly depleted the ozone layer by huge amounts of water vapor into the stratosphere even if it's temporary which is the main reason 2023 will be the warmest year on record.

[abrahamgallegos]

Anyone catch what happened at 6:03? ✂️

[DidivsIvlianvs]

Makes more sense than CO2. CO2 has been rising steadily but warming has occurred in spurts.

[stephennielsen]

Has Dr. Ward submitted his overall hypothesis here formally and for review by peers?

[TheGodofReason]

What? Can anybody clear this up for me? He says that ozone is like a blanket that warms the Earth in an early clip (11:20) then later says that its depletion is what warms the Earth?! Then he says that explosive eruptions deplete the ozone, but that they cool the Earth. Which is it? Do they warm the Earth or do they cool it over all? Can it be either? If so, depending on what variables? And if it's either, what determines the relative strength of the ozone depletion compared to the albedo effect? Anyone got an explanation for me?

[garretthinshaw]

You're mistaken on both accounts, we now understand that the hole over the north pole was caused by nuclear activity, or radiation depletion.

15:00 lol guy just chilling with his cow in front of a huge volcano

[normanmacritchie]

volcano in south pole west side volcano 138 active 91 under ice found in 2013

Refreshing. I hope people listen to this instead of the co2 nuts.

I'm confused he has 5 million subs but 8 likes
