Is there any experiment to prove that CO2 with the atmosphere concentration can have greenhouse effect?
Your question about water vapour is quite a common one among people learning about the greenhouse effect. Once you discover the relevant proportions of water vapour and CO2 in the atmosphere, it's ...

Does rain (temporarily) deplete the surrounding atmosphere of carbon dioxide?
Here is the mass-calculation. We will consider a column of the atmosphere with a footprint of 1m × 1m. This column weighs about 10,000 kg (per square metre). In these days of climate change we will ...

How much does overpopulation affect the carbon dioxide concentration in the air in terms of just breathing?
Human and animal respiration has no global warming impacts. The CO2 released by respiration is in balance with the CO2 absorbed by the plants that became the foods that were the source of the CO2 ...

Why is there so much more silicon than carbon in the Earth's crust?
So where did it go?
Carbon was never there (or here) to begin with. You need to look at this from the opposite way. By asking "where did it go" you assuming the Earth was here first, with carbon, and ...

Is there any experiment to prove that CO2 with the atmosphere concentration can have greenhouse effect?
To see why we can't perform an experiment in lab conditions to verify the greenhouse effect, we need to start by considering how the [rather badly named] greenhouse effect operates:

Why is more carbon in the atmosphere good, up to a certain level?
If plants were growing poorly when atmospheric CO2 was 200ppm, it was probably because Earth was in the middle of an ice age and covered with glaciers, not because plants were starved of carbon ...

Is $\ce{CO_2}$ in photosynthesis the only way for carbon to become organic?
The answer is no. One important mechanism that also fixes carbon is chemosynthesis. One good example of this production is around hydrothermal vents in the bottom of the ocean.
Chemosynthesis is the ...

If methane decays to $\small\sf{CO_2}$ in the atmosphere, shouldn't there be much more $\small\sf{CO_2}$?
So what am I missing in this analysis?
The linked data says 2017 CH4 was about 1850 ppb, not 1850 ppm. Dividing parts per billion (ppb) by 1000 results in parts per million (ppm). In other words, ...

Percentage of power plants with carbon capture and sequestration (CCS) technology?

Does organic decay release the same CO2 as burning?

How much net carbon can coral sequester?
Corals usually grow 1cm every year, some as slow as 2mm, some faster.
Coral sand density is about 1.5g /cm2, it's not the best estimate of coral weight. So, a coral organism of 10cm^2 produces 150 ...
