It's hard for people to know and understand that 93,4% of global warming goes into the ocean, and only 2,3% goes into warming the troposphere... It should be said and explained more often. But if I tell you where to look it up, this comment would be deleted even if it's one of the very official interthingie organization. I really appreciate your work Dr. GeoGirl, but youtube is a rotten org... ☮

[@genghisgalahad8465]

15 minutes is the max threshold to be considered "short," according to...so it's JUST over that, but if it was 20-30 minutes, it would still be phenomenally presented and concisely and visually engaging! I don't think many scientists get to highlight nature and beautiful blue as their relevant background unless it's spectrums of the Sun or galaxies... but earth nature wins them all. 🌌 🏞 🌎 🌏 🌐🏝💧☁️🧭

Loved the video, once again! The weakening of the Atlantic Meridional Overturning Circulation is certainly very concerning! A return to widespread ocean anoxia would be a terrifying prospect. Continent-dwelling humans don't always fully appreciate the importance of our oceans' health. Keep up the good work, Geo Girl!

Really nice presentation Rachel! You have the innate ability to synthesize and present data in a very time efficient and enjoyable format. You have mastered this! On a side note pertaining to olivine….while doing field work in the Delong Mountains of the western Brooks Range our party stumbled upon a massive mountain composed predominantly of dunite and layers of chromite (leopard ore). It was stunning…envision a mountain of olivine! One of those geologic wonders that I have never forgotten.

Very well done! As a lifelong surfer I’ve had the opportunity to travel around this planet’s oceans and beaches witnessing first hand the rise of sea level and the loss of beaches. It’s amazing how much they have changed in just one person’s lifetime. I wish I had a plan to stop the effects we humans have had on our environment, but so far everyone I have come up with results in the reduction of humanity and/or the education of the world’s population and nations that are systematically working to prevent global climate collapse. I wish I had more hope for our planet, but knowing humans we are relegated to climate catastrophe in the near future.

Ocean alkalinity enhancement (Enhanced weathering in general) is a climate solution that really deserves more support and funding

[@ubermachtthemechanic007]

I hear comments help the algo... so here is some support! So sad to see after so many years of warnings we have barely moved the needle toward meaningful changes. What's sadder and more infuriating is the massive bulk of needed change is at the hands of the greedy few who knowingly chose profit over the literal future of our planet.

[@jimthain8777]

While the planet itself will most definitely survive and some kind of life, human civilization is another matter entirely. I don't know about others here but I won't survive long without civilization.

[@harveytheparaglidingchaser7039]

Great video, so much information.

[@Alex_Plante]

I've looked into coastal flooding due to sea-level rise. The areas at greatest risk with very large populations are the low-lying alluvial river valleys and plains of southern and eastern Asia, especially the lower Ganges/Brahmaputra, the North China Plain, the lower Yangtze, the lower Mekong, the lower Irrawaddy and lower Chao Phraya. One thing to consider is the intrusion of salt water into the ground water, making it brackish. Around a billion people live in these low-lying parts of Asia, and they are also the most productive rice-growing areas of the planet, and contain many huge cities such as Calcutta, Dacca, Bangkok, Ho Chi Minh City, Shanghai, Jakarta, just to name a few.

[@jimthain8777]

Parts of Europe, and Eastern North America are definitely threatened as well. These areas are often heavily populated (by humans) and when dealing with the oceans you only really have one option. MOVE! With few exceptions I don't see much movement yet in some of these places. When the water rises, you don't get an option, you move whether you like it, or not.

[@nicholasmaude6906]

8:50 - Anoxic zones in oceans, Rachel, can also lead to anaerobic bacterial blooms which produce large quantities of H2S which is acutely toxic.

[@neleig]

Exceptional presentation! Thank you.

[@danielmalinen6337]

This video clarifies and sum up this well because there is conflicting information in circulation, when some saying that plate tectonics has an effect while some are saying that because the continental plates move too slowly, they have no any effect on the seas and ocean currents. I personally have found the claim that continental plates would have no effect strange and I have doubted it for a long time because it doesn't make sense when you think about it more closely. However, this natural effect is still slower than that caused by us humans

[@bimmjim]

Overfishing has been the biggest destroyer of the global ocean.

You really have endless energy after giving such an inspiring webinar at I telescope 😊. This tutorial is also very informative. Question: Yes- Olivine weathering can remove CO2 from the atmosphere, There are some concerns: What are the effects on marine ecosystems and biodiversity - and also large scale mining of olivine at the scale needed for significant impact?

[@jimthain8777]

This was excellent, and I look forward to the next one. First off, I personally, don't find this depressing, i find it makes me want to do MORE to combat this climate change stuff. Second, I saw a video recently that was shot on a beach on the Yucatan peninsula. It showed a crazy amount of seaweed washed up on the shore. This led me to the idea that maybe it isn't just the algae that are growing in different ways thanks to more nutrients in the seas. Third, Is more, and especially more intense rain likely to cause more weathering which will wash even more nutrients into the seas?

Humanity"s response to earth warming is not only sad, but perplexing.

[@elinope4745]

It's a response to gaslighting. We recycled but secretly the recycle companies weren't recycling as much as they let on. We cut electric consumption, water consumption and had fewer children. People put real effort into ineffective responses devised by bad leaders.

[@curtisblake261]

The perplexing part is the failure to look ahead. If it's still snowing in Illinois, how can there be a problem?

@@anthonyproffitt5341 We went from using glass bottles to plastic bottles for the environment, because the plastic used less energy to recycle. Ends up that recycling glass is actually much better for the environment all along. We have been gaslit with stuff like that for the last 30 years. Many people don't trust what any official has to say because of how many officials have said the exact opposite of the truth.

[@shadeen3604]

Excellent DR GEO GIRL thanks

[@chrismullin9437]

Thank you for addressing and clarifying this topic. It is discouraging but very important. I liked your discussion of olivine weathering, but how would we do that, and is it feasible at scale? Also, I've been particularly troubled by the jump in ocean surface temperature just in the last year. I hope you will cover it and perhaps emphasize that, as the skeptics sometimes argue, we don't know everything, but that it's quite possible that things will be WORSE than we currently project (like your discussion of the number of people displaced by sea level rise).

[@lavaphile]

Hi Rachel, can you speak to where sufficient quantities of olivine would come from? The picture looked like it came from the green sand beach in Hawaii, however olivine beaches are extremely rare. Isn't olivine abundant only in the upper mantle and lower crust?

[@francoislacombe9071]

Is there that much olivine available to make that approach viable? I though olivine was a rock from Earth's mantle, and was rare in its crust.🤔

[@GEOGIRL]

Well weathering pretty much any silicate mineral will help! The reaction should still produce bicarbonate, taking up C and increasing the ocean's alkalinity, it's just that Ca and Mg silicates will help to also promote subsequent CaCO3 formation. So when thinking in terms of silicates, yes there are plenty! It's just a matter of whether it is economically and physically viable and 'worth it' for us to spend our time and money smashing up silicates and spreading them along coasts. I don't have an answer for that, I guess it would depend on how and where it is being done. Great question though! Hope this at least partially answers it ;)

[@joecanales9631]

Thanks, important information. Sea level rise has been a tough prediction and I think too many people discount its significance because they don’t see it. By the time it’s obvious, its impact will have been disastrous. Your home is looking homey, btw.

[@curtisblake261]

Can we revisit some of this more slowly for us mere mortals? Olivine can't be a magic bullet or we'd already be using it.

[@nicholasmaude6906]

In regards to a new video topic, Rachel, what about doing one about the various carbon sequestration projects going on? IMO I think the method Iceland is using is very interesting and promising.

We aren’t the first organisms to negatively effect the earth’s climate. I’ve known that for awhile now but I’ve never really thought about it like that.

[@GEOGIRL]

Yea, and I mean the term 'negatively' is also relative, because even organisms that caused major climate change and mass extinctions (like the first photosynthesizers that caused the great oxidation event or 'catastrophe') typically led to greater biodiversity after the fact, so in a lot of ways, the long-term changes were 'positive' or beneficial for life on Earth, but of course at the expense of other groups.

Ocean anoxia cycles linked to Milankovitch/ice age cycles on Earth? Mars dry ocean beds could also show anoxic conditions which would be an important biosignature. Much easier to detect since ocean sediments there would start only a few meters below the surface and the northern half of mars is entirely a dry ocean bed.

I have a sump pump pit that is basically a well, we have ground water in my neighborhood for some reason. I wonder what is going on under ground, not just in major aquifers, but even in neighborhoods, everywhere, how it moves around, where it accumulates and why. You probably will not see this, the video is a week old, so I probably will request this again.

Ocean fertilization could also reduce atmospheric CO2, but we need to study the effects of the algal blooms. They may be beneficial only in certain areas and at certain times of year.

Dear Geogirl, you're knowledgeable. But the art of geology is a tad more complex than sometimes you suggest. Generally, I agree with your explanations which are above what's found in the Net about geosciences. However, your ideas on Climate Change are somehow simplistic. You should have a look on Morner's work in 2015 (he's dead alas). In the 80s he was right against the so-called scientific consensus on worldwide ocean level cycles. He was right against 90% of geoscientist of that time. Whatever, I like your enthusiasm. P.S. I'm an old geoscientists from the times when plate tectonics was a hypothesis. I'm Le Pichon's student.
