Sorry this was a few mintues late this morning! I completely forgot to schedule it! lol Hope you enjoy ;)
No worries! We are here for your wonderful ability to explain complex geoprocesses. What's a few minutes?
You're grounded!
(see what I did there?)
A few minutes doesn't matter, Rachel.
I'll be waiting for some more😊
Don't worry, Rachel, your videos are always worth the wait🙂.
Back in the day while bicycle touring in the Hawaiian Islands, I remember visiting a beautiful green sand (olivine) Mahana beach on the big island. There were olivine outcrops on each end of the crest beach formed from an eroded cider cone which were weathering to produce the green sand. To think one of the geoengineering solutions to mitigate climate change might be many, many more green sand beaches would be a lot prettier than millions of atmospheric carbon capture machines humming away.
Climate has been changing on earth since time began. It isn’t because of humans.
Yes we are polluting earth. But regular people aren’t changing the climate.
The magnetic poles are currently migrating at an increased rate. They move every 6,000 years.
Other planets poles also shift.
Our climate is also affected by the Sun and what it’s spitting our way.
Climate change is a fear monger way for the more powerful to control people and how they spend money.. (electric? It isn’t better for the earth. Batteries require heavy mining)
Rachel: I truly appreciate your presentation. I also know that it can be controversial in some camps. I place my confidence in you as a highly qualified geoscientist and that all your presentations are based on accurate data and sound scientific interpretation. Thank you for seeking answers to help us understand these complex issues. Keep up the good work!!
Rachel is back with a new video ✨️
Geo Girl rocks! Just like the Earth! ❤🎉😊
"Don't worry about the chemistry..." Famous last words! 😂
So many spheres, so little time. Thanks, Doc. Your vids are welcome whenever they show up. You're always worth waiting for.
i have zero connection with the field of geology but interesting to see how surprisingly (for me) relevant it is. great vid, doc!
Your channel is one of my favorites, you present a lot of material, a person can learn a lot. I like the fast pace, I figure I can listen multiple times to pick it all up if I did not take it all in. One of the best channels I have seen imho. At least as I define "best".
You do such great videos! Keep up the good work!
I love the lecture and I look forward to the next one! You may have heard about this - a few start up companies are experimenting with spreading very fine grains of basalt over farmland to speed up the weathering process and eventually sequester carbon. It’s called “enhanced weathering.” It works, but whether it can be operated at large scale to make any significant difference remains to be seen. Thank you.
Dear Rachel 🍨,
Thank you 🙏 for the informative video 📽️.
👏👏👏👏👏👏👏
New Geo Girl videos always make my day :)
Excellent diplomacy with the skeptics :), love that you take time to focus on the lithosphere where the slow timeframe of regional change can make it seem less involved in Earth cycles to us humans. Keep up the scientific statesmanship!
Of course the "skeptics" are anti-science hustlers who deny climate change for partisan political and crude commercial reasons.
Thank you so much for your videos. Geology is not my field, yet I learn so much from your videos, not the least of which is learning to think scientifically about geologic processes and by extension other processes as well.
Good day and thanks
Love from himalayas❤
Thanks for the info, have a good day
Amazing information ❤
14:55 Animals that can do non-oxygen respiration, also includes goldfish. When ponds ice over for long periods, and the water becomes anoxic, most fish will die. But goldfish will switch to metabolizing their fat anaerobic. This process will give the goldfish a blood alcohol level above the limit for drinking and swimming, and they are at risk of losing their swimming license. Seriously though, this allows goldfish to survive the winters in small ice covered ponds.
Olivine is such a pretty mineral! I actually bought a necklace of it after learning about its carbon mineralization potential. Wollastonite is another good one. Currently I'm doing some home weathering/mineralization experiments with basalt and diabase (not as nice-looking for jewelry)
Another masterpiece in science divulgation
Excellent video!!
Another great video! Cool background as well!
I saw a documentary decades ago on how erosion of the Himalayas was releasing CO2. I started thinking abut how much CO2 is in carbonate rocks. It has to be that most of the CO2 on the planet is in rocks since there is so much limestone. It can be broken down by any acid and it's right out there exposed to rain every day. I hadn't heard anything else about it since then. Geology is slow until it's fast.
Thanks geogirl.
I wish i knew someone like this irl
Liked and subbed
Excellent video 🏆
It is sobering to realize the surface of the earth we depend on is just bathtub scum on a geologic time frame. I've only recently come to appreciate just how large a role life plays in remodeling the planet.
Thank you for continuing the channel after completing your degree.
Can you give examples from the lithosphere or from artificial compounds of calcium carbonate (perhaps magnesium carbonate as well) where the main component is CaCO3 and there are accessory minerals? These accessories/dopants would convey resistance to acid weathering. Basically, if we sequester a huge amount of CO2 in limestone, can we also include small amounts of other substances so that the limestone better resists returning its CO2 to the atmosphere.
Let's assume that simple physical quarantining isn't a reasonable option at this scale, so the sequestered CO2 in limestone will be exposed to dilute carbonic and sulfuric acid.
I'm usually wondering, when are we going to have another volcanic winter? How bad will it get? Don't have to answer, I budget some time to look at what's already available. A VEI of over 6 would be substantial, and inevitable over some time.
great
Well done
Howdy Dr. Rachel. Made pancakes this morning so you being late wasn’t noticed (I make a bunch for later in the week).
Here’s a topic I have wondered about: how does having liquid water at the surface influence plate tectonics.
See you next week
Thank you Dr. I'd love it if you could make a video on the current interstadial (the Holocene) and the 20 or so glaciations that cooled the climate since the start of the Pleistocene. Incredibly, no climate scientist talk about those facts. Where I live (southern Québec) there was about 2km of ice just 25 ky ago!
" Incredibly, no climate scientist talk about those facts. "
Great question! Actually, I have many videos going into that and how the fact that we've been in an ice age for a bit (and general cooling trend for even longer, ~30 mil yrs) makes the current warming trend even more dangerous to the relatively cool-adapted life on modern Earth. But I will certainly try to do a future video specifically deticated to that because I think that is a great idea and also can be misunderstood. Thanks for the idea :)
@Theoriginaldanwhatever
Dude, you don't know what you are talking about. It looks to me that you did not verify what I wrote. I read all the articles on the analysis of the Greenland and Antarctica ice cores. Do your homework and check it for yourself instead of playing the sucker!
@@GEOGIRL Well, we are at this very moment about 12,6 ky into the interstadial named the Holocene. Check the research on Greenland and Antarctica ice cores since they are my references. According to those analysis, we are close to the end of the current interstadial since they last on average from 10 ky to 15 ky. The maximum thermal of the Holocene was about 6000 y ago. Since that time average temperature go down toward the next glacial. There are no reason to think that the next glacial will not happen. So indeed, it means we are close to the beginning of the next glacial cycle. Check the data, the facts please. This is important because the current human induced warming might save us from the next ice age! I am not a climate specialist but I am a senior electrical engineer and I've done my homework as far as the past Earth climate is concerned. Please, we need an unbiased evaluation of ALL the facts.
@@quantumcat7673" There are no reason to think that the next glacial will not happen. " - yes, there is. It's called temperature increase due to disequilibrium. Get a clue and stop pretending to know something.
12:46 'Feedback' has become a euphemism for 'it'll work itself out'.
15:00 let's not lose sight of the forest for the trees, the overriding problem is acidification (not anoxia etc).
16:39 olivine doesn't sound scalable. You'd need something driving a cycle with energy, like the plankton sequestration engine, not infinite mass to add
Does the O reacting with Fe necessarily come from the atmosphere? Could there be a reaction sequence that draws the O from the silicate minerals in the rock?
5x5 Datil NM USA Hello Geo girl,love them comments,you have everyone thinking how to detox the earth with oxides WOW nice work
When the Iron in Iron Ore Rocks reacts with Oxygen to form Iron Oxide, how does it lose that Oxygenation to Reform back into Iron Ore? Or does it do this with only one time around as an Iron Ore? THANK YOU Dr. Rachel.
Beautiful graphics! A pleasure to behold. btw: When you do the presentation on "Urban heat island effect" be sure to mention how that has skewed such a large percent of temperature readings on our weather stations that it gives the false impression that we are undergoing global warming.
I have not read all the comments. Is there a thread about effect and affect?
Cooling the planet by increasing Albedo is very energy efficient, consider exploring that instead of focusing on co2 alone which takes centuries to return to previous levels without any impact on heath
I heard that the generation of the Himalayan moubtain chain, and how quickly it formed was responsible for a global climate cooling. Mostly because it created an area where late accumulations of rain would form because of the height that was not there before, and then also that a large amount of the rock being uplifted had high silica content. And the combination of those two variables in addition to the fact that during that time, which was a fairly warm time in earth history, due to high concentrations of CO2 in the atmosphere lead to a mildly acidic rain that contained CO2+H2O lead to the dissolving of the dissolving of some of the Silica newly present in the Himalayan. I think it’s called Silicate Weathering. Anyway, I just wondered what your take on the rising of the Himalayan mountains leading to a global cooling was. Is there any validity to others’ claims? It seems to be a bit controversial. And seeing as your area of study is geochemistry I figured you’d be a good person to ask. Sorry if you already did a video on this.
"Have you ever wondered..", about absence, empty space that goes on forever and lasts eternally.., going on like it must be absolute Perpetual Motion, ie in e-Pi-i sync-duration connectivity function absolute fact of existence?
So the density-intensity alignment of information In-form-ation substantiation absolutely extends to rocks in the Lithosphere and the wonders of Math-Phys-Chem and Geometrical Compositions of nodal-vibrational emitter-receiver interference positioning resonance bonding holography, Pure-math dimensionality coordination shaping WYSIWYG QM-TIME Completeness.
What is it exactly that makes the symbiotic algae leave their coral hosts when the temperature gets too warm? It's not like it's an unavoidable effect, some species of coral do manage to keep their algae helpers under those circumstances. 🤔
Great question! It just depends on the specific species of coral and algae involved because they differ in their preferred temperature range ;)
Can we release oxygen by desalination (or any other processes) into the atmosphere in order to change the CO2 ratio?
What processes can balance the CO2 and methane ratio in the air?
"Can we release oxygen by desalination (or any other processes) into the atmosphere in order to change the CO2 ratio?" - it's easy to break water into H2 and O, all you need is lots of energy. And the ratio of CO2 in the atmosphere is less important than the total.
Hello madam I am from Pakistan, I am working on Cretaceous anoxic event on eastern Tethys ocean (Indian Plate), especially OAE 2 boranalli event using proxy of biomarker TEX 86 and also use software like GIS, Global mapper, Move, Google earth and Corel draw etc.
Please make a detailed video on biomarkers and how it related to paleoclimate. Hope my request accepted.
I am learned so much of you watching all the videos of you.
Any help regarding software I am available. My CZcams channel is Geology Software.
Increased carbonic acid levels does horrible things to zooplankton that have carbonate exo-shells.
If I remember right, oxygen solidifies to a metal when it is cooled toward absolute zero.
When oxygen is included in a mineral structure, do the oxygen atoms contribute to the weight of the mineral? Does it act as a metal when it is held within the mineral?
Metals are malleable substances that share their electrons freely across the atomic lattice, making them good conductors of heat and electricity. I can't think of any oxides that have those properties at normal temperatures and pressures. Whether an oxide can become conducting or even superconducting at high pressures or low temperatures is a good question.
Minerals rock!
Which current climate trend? Leaving the last ice age?
Human caused global warming since 1950s
Let me guess: you think you know something about climatology though you've never taken a geology class.
The unprecedented warming since 1950's.
The Ice Ages lasted two million years. The present climate catastrophe is happening over a scale of decades. Climate change deniers carefully overlook this fact.
Whoever I hear about all these cycles and interconnected systems, it makes me wonder how things might be on an alien planet.
You should change your title to Dr GEO GIRL.
Hello Rachel it's febuary now are you able to do an interview with me do you still use your University of Texas email?
Are you study geomorphology
Clathrates. More stored carbon than all the oil, and coal, and gas put together possibly. No one really knows it hasn't been studied.
I doubt there is any way for humans to accelerate chemical weathering without expending more energy than it is worth. We just need to cut our fossil fuel emissions,
The carbon cult continues.
Just a heads up....
The more your professor pushes her beliefs on you (as her university bio says she does) about "climate change"/hysteria, the less people will follow you.
I already find myself passing your videos as you start to lean towards full leftist, "climate change" activist.
But goodluck in your endeavors.
Hi there, I am actually the professor in this scenario, and I am teaching a climate change class this semester, which is why my videos are heavily climate related at the moment. But I am not pushing my beliefs on anyone, I am teaching facts and data. It is not fun for us to teach about climate change, believe me, it is quite depressing, but we have to because we need to do something about it. I am sorry that you don't enjoy these videos as much (to be honest, I don't either), but I hope you'll stick around and learn about these topics with me. But if not, that is fine too, I am not going to stop trying to help spread the science so that more people understand what is really going on. :)
@@GEOGIRL" I am sorry that you don't enjoy these videos as much " - if I may plea with you, do not feel the need to apologize to the malicious know-nothings. They strike out at experts because they are angry, and lazy.
Maybe it's just you. Maybe it's because you refuse to learn real science.
@TheOriginalDanEdwards "real" science...?
The kind where beliefs ARE NOT supposed to be part of the process ?
You can't blah blah your way around the fact that higher education and the scientific process are losing credibility faster than than ever BECAUSE of the very issue I'm talking about.
This nonsense where "researchers" bring their own beliefs in to the process is a thing called confirmation bias. It's when you BELIEVE something is true and then seek out only the information that confirms your belief. Which IS NOT "real science".
Become more educated before you engage me, to do otherwise will have your lack of, brought to light.
@TheOriginalDanEdwards or, we question things that make no sense.
A researchers beliefs are not supposed to be part of "real science".
There's a thing called confirmation bias. When someone believes something, their belief will bias the research. Anything that confirms their belief, will be elevated and pushed as fact. Anything that doesn't agree with their belief, will be discarded.
