Question: if carbon dioxide is heavier than “air”, it seems the biggest cause of atmospheric warming is due to dumping tons of carbon dioxide at 37,000 feet by every jet in the air. Ground level Co2 is recycled by plants, but there is no natural way of clearing upper atmosphere co2 emissions. I’m no expert by any stretch and only suggesting the majority of our problems could be from those flights around the world. The other comment I’d like is how we ignore the elephant in the room – energy use. Every traffic light that ignores current traffic flow wastes enormous amounts of energy. We need to figure out how to be far more efficient and stop wasting energy.

No, CO2 is mixed pretty evenly by wind and convection in the atmosphere.
LDoctorKC

A 747 takes off with 400,000 lbs of liquid carbon, 787 maybe half or so. You oxidize that fuel and carbon becomes carbon dioxide (generically speaking). In the upper atmosphere, things are much different, and while I agree ground emissions are bad, imo it doesn’t compare with dumping it in the upper atmosphere.
LDoctorKC
May 4, 2022 at 5:54 pm
@Dave Byrne good point, but short of a volcano, surface airflow is different than above. It does mix, but we’ve seen two cases of weather changes due to flight cancellations. 911 and COVID.

If CO2 is heavier than air than how does it stay suspended in the upper atmosphere? Wouldn’t it just sink down to the troposphere, or all the way to the ground for that matter?

We use the term climate change a one way change and assume it’s “good or bad”. During the pandemic when flights and transportation fell off drastically, it created climate change. As you lower carbon emissions or change the landscape by covering grass with panels, it will change the climate. Remember, most weather events happen in the spring and fall during the change in seasons. The planet is seeking equilibrium, and all change is not confined to one aspect. I do not believe we should be hyper focused on only one aspect.

It’s already too late and global temperature will rise at least 2 degrees. Too many feedbacks are in play… major methane releases in Arctic regions, collapsing ice shelfs, fires causing more carbon release and people avoiding reality because they aren’t hurting enough. The first two problems caused by rising global temperatures are already happening with more outbreaks of diseases and increased storm damage. The third problem will be food shortages caused by crop failures. Flooding of coastal areas including major cities will be last.

I’m so tired of the catchphrase “climate change”. This is just part of the natural planetary cycle that Earth has been through many times. Yes I said NATURAL planetary cycle. Because no matter how awesome and how impactful we believe ourselves to be, the earth produces its own system of checks and balances- even with us trying to f*** everything up. It has been able to overcome past warming through an increase in thriving plant life which absorbs CO2 and produces oxygen as a bonus. All the hottest parts of the Earth’s history were marked massive increases in photosynthesizing plants. These man-made carbon capture factories that are being turned on to pull the carbon dioxide out of the air are just going to exacerbate the problem. The methane coming out of the oceans is producing far more CO2 than anything humans could ever hope to produce. That said, if they keep capturing it out of the atmosphere they’re going to kill plant life in one hemisphere or the other, which will only compound the warming problem and the buildup of greenhouse gases. Let’s just plant trees and other green plants and let them do their thing!

Enormity: The quality of passing all moral bounds; excessive wickedness or outrageousness.
A monstrous offense or evil; an outrage.
Great size; immensity.
Perhaps a different word might be better used to express great size; immensity so that people don’t interpret enormity as excessive wickedness or monstrous offense or evil.

“Computer modeling”. When was the last time any of these models were even remotely close to observed reality? I suppose it doesn’t matter because climate change will wipe us out in like 12 years. Of course they’ve been saying garbage like that since the 90s.

For the first time in history, all of humanity is facing a common external enemy. This enemy is the climate. In the face of planetary danger, it is necessary to unite all people for the future of humanity. Because we are people, and we want to live.
I invite all caring people to a unique event on May 7. International online forum “Global Crisis. We are People. We Want to Live” is a large-scale and unprecedented event, organized thanks to the independent unification of millions of people from 180 countries on the Creative Society platform.

People who go to college in America are the dumbest Americans that exist. And they spend the rest of their lives in debt to their dumb choices. They also spend the rest of their lives limited to doing one thing, the thing they studied in school. This is the most un-organic way to live your life. No one 19 year old can make the decision “what should I do with the rest of my life?” That is a lifelong question that takes many attempts to answer. So you fell for the education scam. Sorry not sorry. I am not paying your student loans.

I think she’s comparing the collapse of the Arctic land with other land closer to the equator being developed for humans or turning into a desert from climate change. It makes sense because the earth is essentially tilling itself throughout the Arctic like at 2:03 without the need of a bulldozer.
