Thank you for the lecture

That was a wonderful intro. Who knew.

Your lectures are very helpful,thank you professor!

A very good oceanography tutorial, with vivid and easy to understand explanations. thank!

Cyanobacteria ("blue green algae") are not plants, they are bacteria and predate the evolution of photosythesizing plants because they are what formed a symbiotic relationship with early plants to develop chloroplasts. Cyanobacteria were the first and only group to develop oxygenic photosynthesis. Without them plants and animals would of never existed. And Metazoa (animals) are by definition multi cellular eukaryotes. It's also weird that that documentary reffered to stromatolites (literally "layered rock", sromatos lithos) as organisms, they weren't, they were made excretions by lyers of organisms like cyanobacteria. And essentially the cyanobacteria shit out O2 from H2O so much that they repeatedly knocked themselves almost extinct many many times by increasing the atmosphere and water with their own waste, until this happened so much everything wither adapted or died. This is thought to be the largest extinction event ever, called the Great Oxidation Event.

Very informative lectures. Thank you

Hey man! I don't know if you still reply to anything anymore but I really appreciate these videos, I'm an aspiring meteorologist and these videos are helping me prepare for college!

We are a fulltime sailing / cruising family. We are watching this series as a family as Understanding weather is extreme!y important to our lives at sea.

Thanks Dave. I've just been through this whole series as part of my pilot training. It answers so many questions for me. The most exciting thing is all this learning is a never ending process. Even though my focus is aviation I'll possibly go through your ocean series as this one was such a demonstration of quality.

This needs to be apart of living in Florida. 💯

Phenomenal Finally someone who can provide historical connections

This is awesome, im glad i found this. Been thinking about going back to college and finishing, then going to uni for meteorology degree. Niceee

soooooo much to take in at onceeeee

Thanks !

Excellent lecture. Based out of SW Florida ...we will be seeing a busy hurricane season ..predicting 27 storms 14 hurricanes and 8 major hurricanes ...hope everyone will be safe

Great ! Thanks

Thrilling and great explanations ! Thanks

Thank you!

So if condensation nuclei are particles like dust, salt etc, then there must be a lot of rain after a nuclear explosion.

This is neither a solicitation nor an invitation, this Is the truth. I am and have been completely abstinent for what will be eight years (05-22-2016) (excluding one part of one day now in 2016) here in Philadelphia PA USA almost eight years, and (with the exception of one day in early 2018 not in Pennsylvania), and never left America). My eldest son (who is diagnosed with a disability, but who I am teaching) is still a virgin (to my absolute very, very, very, very, very,very, very, very, very, best knowledge), and my youngest son is married and had a baby girl with his wife a month ago. 05-23-2016 (while I was running for Congress, I spoke with Yvonne Seminario about working as a Financial Advisor). It is now, 03-13-2024 or whenever this stops, nor do we have STI's or STD's, no Cancer, no COVID-19, not LGBTQIA and do not have sex, I do not have a menstrual cycle at all, nor have been sexually active in years, am not cheating not microcheating, not little bit cheating, , not having any affairs, did not sleep with my brother, sister, or children (sexually) just shared a bed, nor my brother in law, nor expose our fathers, not fornicating. I was praying (not playing on September 11, 2001). We mourned.

I have never heard gyre pronounced with a hard G, viz. 'guy're. Is that a regional southern thing?

This is neither a solicitation nor an invitation, this Is the truth. I am and have been completely abstinent for what will be eight years (excluding a few days in 2016) here in Philadelphia PA USA over seven and one half (almost eight) years overall. (with the exception of one day in early 2018 not in Pennsylvania), and never left America). My eldest son (who is diagnosed with a disability, but who I am teaching) is still a virgin (to my absolute very, very, very, very, very,very, very, very, very, best knowledge), and my youngest son is married and expecting a baby girl with his pregnant wife. 05-23-2023 (while I was running for Congress)-01-26-2024 or whenever this mess stops, nor do we have STI's or STD's, no Cancer, no COVID-19, not LGBTQIA and do not have sex, nor have been sexually active in years, and no longer have a menstrual cycle. I was a virgin when I went to college, and was at home praying on September 11th 2001 as well as election days (normally). I have not been paid by my job in 39 weeks. I took no bribes. Definitely never robbed any banks. I am not remarried, nor am I engaged.

What is the best time for snow plows to move snow and melt ice?

If there was more water near the sun (or a water source), would it be less likely to explode?

Did he really not even show the Keeling Curve? Look up the Suess Effect The increase we have seen in atmospheric CO2 has not had the relative proportional increase in the radioactive 14C isotopes that are depleted in fossil fuels but it has increased in 12C. So yeah, we absolutely know that the overall increase is caused by fossil fuels because that radioactive carbon is depleted and the only thing being released into the atmosphere that is old enough for those radioactive isotopes to be depleted are fossil feuls, mainly coal. We absolutely know the increase is anthropogenic. It is absolutely ridiculous to say "potentially even man made global climate change", we absolutely know that there is anthropogenic warming due to human release of GHGs. And the proportion of 12C we are adding can't simply be sequestered into plants to solve the problem, even partially, considering that is a small carbon sink, plants are extremely sensitive to input fluctuations (that can happen over extremely long periods of time but not rapidly), and that we are also causing record deforestation. The plants just aren't going to "get larger and greener". And it will have a different impact on C3, C4 and CAM plants. And maybe you should specify the time durations involved in the Carbon Silicate Cycle and other processes so that students don't mistakenly think that those are short term effects that can assist in combating anthropogenic climate change.

Thank you so much for your lectures.

Thank you for sharing your lectures they are very informative!

Thank You SO Much! I use this for science olympiad. It really helps me, because I am a seventh grader and the chapters aren't the most comprehendable.

Thank you so much for such significant content

There’s your triple point at 45:22 underneath the L! It all makes sense now

Absolutely superb series. I’m soaking up every bit of it and i love the way it’s being explained. Very easy to understand. Thank you so much!

foehn (or föhn) is also german for hair dryer! Thank you for the online lecture, I am very much enjoying learning from you :)

Elements beyond iron cannot be formed by forcing other elements together, no matter how extreme the heat and pressure. Instead the process in supernovae that forms heavy elements is neutron capture. Planetesimals and protoplanets are not the same thing. Planetesimals are what forms directly from the dust of a new star system. Protoplanets form from planetesimals by partial melting and separation into a core and mantle. The mantle is solid rock. It's just that the weight of miles of rock above it is enough to make solid rock flow like soft wax. Also, that applies only to part of the mantle. The lithosphere (i.e. the part on top that doesn't flow like squished wax) includes both the crust and the top part of the mantle.

The best meteorology courses on the internet. Helped me through all my aviation exams . Hats off to you sir and thank you from the bottom of my heart!

First comment on youtube, your course is so helpful Prof. Dave, thanks and greeting from China!

Life saver for my atmo exams; thank you!

So helpful :)

These videos are incredibly helpful thank you thank you so much for such an amazing content. You are an awesome teacher!!

How much is Shell paying you? 🙄
