Global warming was officially stated at 1.1°C in 1991 and 1.06°C in 2022. There is no mechanism that would allow greenhouse gas behavior to cause global warming. The back of the United Nation's IPCC science report states it took its greenhouse gas samples at 20,000 meters altitude where it is common high school level knowledge there is no greenhouse radiant energy. This is typical practice for deceptive marketing to state legal data transparency protecting the perpetrators from fraud prosecution. Earth's greenhouse effect is frequently used as a primary example to high school students of a system always in saturation from the strong greenhouse gas water vapor absorbing all the greenhouse radiant energy from the earth with greenhouse gases within 20 meters of the surface that is all around us everyday and can't have its overall effect changed. There is no further greenhouse radiant energy to interact with greenhouse gases. At 1% average tropospheric water vapor over 99% of earth’s greenhouse effect is from water vapor. Water vapor would hold earth's greenhouse effect in saturation if it were the only greenhouse gas in the atmosphere. Arctic warming is taking place with the proving mechanism being warm Atlantic Ocean waters migrating deeper and more frequently into the Arctic Ocean warming it and the region. That warmer water is causing a few weeks less of reflective snow and ice coverage resulting in more solar heat gain to the Arctic region surface. Atmospheric CO2 levels of 1200 ppm about three times what they are today would greatly invigorate C3 plants the majority of plant life on earth greatly greening the planet. 0.4% of the atmosphere is CO2 and on average 1% is H20 water vapor. (1% H20)/(0.4% CO2) = 25. Water vapor is 25 times more present in the atmosphere on average than CO2. Water vapor has an CO2e of 18, 18 X 25 = 450 CO2e total for water vapor to 1 CO2e for CO2. The Earth’s oceans have 3-1/2 million sea floor volcanic vents warming the water and changing it’s chemistry that have not been systematically accounted for.

Pure Propaganda,.....

As someone with a masters in earth science I will enlighten the crowd about the false info here. First the opening picture shows smoke coming out of nuclear water towers. This is not CO2; it is water vapor. CO2 is invisible & odorless. She neglects to include water vapor which is the most potent ghg by volume & by potency. The range of water vapor is 1-4% on the planet; it has a quicker residence time. CO2 is a distant #2. Vapor exceeds water vapor in power by 97X. It has a longer residence. She also does not tell the audience that the planet has sinks. Only those in meteorology would know this. The sinks are all oceans & seas; all vegetation from plankton to redwoods; & the sediments (limestones). Heat increases lead CO2, not the other way around. This is what I mean by the cultists really neglecting the science. What greenhouse gases do is interact with very specific photons of IR light (thermal portion of sunlight). If a specific photon fits into the molecule, it absorbs it & immediately emits it. The photon can now either bump into another molecule or exit to space. In this respect water vapor has many more windows open to different photons. Furthermore, just as water vapor saturates the air & as you know-it releases the latent heat of condensation via rain, clouds, fog, etc, then CO2 also has a saturation point. Most of the work done by CO2 is accomplished in the first 150 ppm or so. After that the temp incline stabilizes. What it means is under a hypothetical doubling, the IR reradiating off the ground cannot penetrate a denser layer of CO2 to heat the air above. The height is confined to 1/2 each time.

beautifully explained.

helped me a lot.

perfect.

Methane absorbs at 3.3, 7.7, and 12.2 um. Blackbody radiation of the earth is 9.6 to 15 um. Water absorbs radiation at 2 to 15 um, meaning methane absorbs only one useful band which it shares with (massively abundant) water. The "methane is a worse green house gas" is a lie; the impact of methane today is only high because there is so little of it.

Wow. What about water?

👍 ρяσмσѕм

I wish you all the best

Thank you Summer

Thank you it is very helpful

thsnk you but what about bushfire and eruption volcano which scope do they are

Carbon is good for plant life. We're not doing this any more, sorry.

It is helpful..., do more videos on climate. 👌🏼

Thank you so much for sharing this wonderful webinar 🤩🤩🤩

*Put* *that* *cookie* *DOWN!!!!* 🍪

What is the 7th category of GHG? Did I miss it?

Dear, Ma'am /sir team we are (geography students of A. M college) from India please give a opportunities some things to do please🙏🙏🙏🙏🙏🙏(brindabankumar5@gmail.com) Thank you

Given that half of the American population is not capable of reading a book written at the 8th grade level and that one-in-five cannot independently fill out a job application form, it’s understandable why public comprehension of the greenhouse effect (taught in junior high) is limited. Though classroom demonstrations can help overcome this difficulty, shortage of funds and overworked staff can make that difficult. And I’m not sure what would help older adults. Therefore, the use of teaching videos from TH-cam at home could be useful (though these are limited in some ways): samslair.blogspot.com/search?q=Greenhouse+Effect+videos+&m=1

Thanks

Thanks for the good discription

Well hopefully CO2 will stay in the atmosphere forever, otherwise plants and subsequently all life on Earth will die out. Hopefully H2O, the biggest greenhouse gas, will also stay in the atmosphere. Blaming CO2 is like blaming H2O, a complete nonsense: plants love both

Um, please read up on this a little bit. You didn't even MENTION the largest greenhouse gas. H2O. Honestly, greenhouse gasses have very little to do with climate change. (It's mostly the sun, in case you were wondering.) But... if you must regurgitate what you've seen on CNN, please learn to read a teleprompter better. You really suck at it.

Who paid this idiot to perform in this video? Greenhouse effect is a *MYTH* people!!!

Dislike! Video is awfully WRONG! Greenhouse effect doesn't exist because all gases are that same...

Thank you! really useful

Just to clear the haze in understanding - we mean to say even though Carbon di-oxide due to its prevalence ( Volume ) attributes to a higher Green House Gas Effect at the moment, however for same volume of gas Methane ( having a higher GWP ) would account to a higher Green House Gas Effect?
