Atmospheric CO2 Levels

The cluster discusses rising atmospheric CO2 concentrations, emission trends, absorption by oceans and land, historical comparisons, and debates on its role in global warming versus benefits for plant growth.

Sample Comments

- CO2 is plant food. Indoor growers supplement CO2 levels up to 1500 ppm (after which they say that there is not much return) to enhance growth. There is no reason to remove it from the atmosphere.- Supposedly CO2 is also a green house gas that helps earth trap some heat from the sun. The link between how much heat CO2 captures based on the concentration is very difficult to find, suggesting that the link is not very strong and propaganda driven "climate science" deliberately doesn&

CO2 is still in the atmosphere.

can you provide a link to the CO2 being dumped increasing ?

They were probably releasing too much CO2 into the atmosphere /s

Seems like global warming and higher atmospheric CO2 levels correlates well with the timeframes.

What is causing atmospheric CO2 to increase? What do you think is going to happen if that keeps increasing?

s1artibartfast Oct 27, 2023 View on HN

you are messing up your derivatives. There is:1) atmospheric CO22) how much the atomospheric CO2 changes per year3) Is the yearly CO2 change speeding up or slowing down.This data and the article are about the third factor, which is tied to peak annual emissions. The analogy for a car would be:1) location2) speed (change in location)3) acceleration/deceleration ( Is speed going up or down)Based on the article, it possible that 2023 may be the first year that car isnt

You [1] emit CO2 from the food you eat, so absolute zero CO2 emission is impossible. There are also emission from volcanos.For a somewhat similar scenario, you can read about the Carboniferous period https://en.wikipedia.org/wiki/Carboniferous . Essentially, the plants invented the wood but nobody know how to eat it, so the dead plants accumulated sequestering a lot of CO2. So the

https://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth%27s_at...If you look at a chart like this, and think: hmm, this is probably fine, you've completely lost the plot. Something is going to happen from this, and its probably not going to be fun.
