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 ...

Oscillations in the Keeling curve?

Photosynthesis increase in the northern hemisphere spring, especially in the Siberian Taiga, and carbon dioxide decrease in atmosphere. During autumn and winter, decomposition of plant material and ...

Are there pockets of liquid carbon dioxide in Earth's oceans?

Yes, according to this paper in the Proceedings of the National Academy of Sciences. But they also say that this "lake" of liquid CO2 is covered by CO2 clathrate, so it's not quite your average brine ...

Is there any experiment to prove that CO2 with the atmosphere concentration can have greenhouse effect?

Experiments don't necessarily prove things, per se; and in particular, a single experiment tends not to prove anything - at the very least, replication of the experiment is required. Experiments ...

Can I use diamonds as fossil fuel?

Diamonds are expensive. Really expensive. Even "cheap" synthetic diamonds are orders of magnitude more expensive than conventional fossil fuel. By using them as fuel, you will increase ...

Why has CO2 decreased in the history of the Earth?

The short answer is that most of the Earth's original allotment of CO2 got locked up in various carbonate minerals, largely calcite (limestone, marble, and chalk). According to this article there is ...

Time relativity relating to Carbon dating?

Earth travels along its orbit at about 30km/s. If you plug that number into a time dilation calculator, you'll find that one second on Earth passes every 1.0000000050069 seconds in a Sun-centric ...

What is the difference between a carbon sink and a carbon reservoir?

The difference is that a carbon sink accumulates carbon, whereas a carbon reservoir has accumulated carbon. That is to say: A carbon sink is an ongoing process which is increasing the amount of ...

Is there any experiment to prove that CO2 with the atmosphere concentration can have greenhouse effect?

The short answer to your question really is just this: Yes, CO2 causes global warming. There are many resources out there on the internet that explain this in about as much detail as you can tolerate,...

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: The Earth is in (...

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 ...

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, ...

Does organic decay release the same CO2 as burning?

I can't quantify the answer, but intuitively, nearly all of a burning tree's carbon is converted to $\small\mathsf{CO_2}$ - assuming the fire is hot enough. You are correct in assuming that termites ...

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

If you accept GE's estimate of the number of global fossil fuel power plants ( 17,500 ) and compare it to the number of CCS projects out there ( 22 ), you get roughly 0.1 %. The Global CCS Institute ...

In an Earth-like planet with no history of carbon-based life forms, would there be limestone?

I'd have to say, yes. Once life evolved in the world's oceans, the vast majority of limestone formation has been through the organic process. However, before life did evolve, limestone formed through ...

What is the difference between a carbon sink and a carbon reservoir?

A carbon reservoir is measured by the amount of carbon it contains, for example kilograms of carbon [kg C]. A carbon source or sink is measured by the amount that comes out or into the reservoir from ...

Are there pockets of liquid carbon dioxide in Earth's oceans?

There are several reasons why the ocean floor is not a pool of liquid $\ce{CO_2}$: Solubility of gaseous $\ce{CO_2}$ in brine is low. Mass transfer of gaseous $\ce{CO_2}$ from the atmosphere is ...

Why has CO2 decreased in the history of the Earth?

No, it is not due to lush vegetation (that was not around until just hundreds of millions of years ago). The period around 2.5 billion years ago is known as the Great Oxygenation period. No one ...

Does organic decay release the same CO2 as burning?

The key word in your query is the word "essentially". Termites and bacteria die too. So whatever carbon was initially converted from the tree into termites or bacteria ends up mostly going to $\small\...
