I asked Chat GPT a few simple questions.

Q: Which countries have oil reserves and how much?

A: Here are the countries with the largest proven oil reserves, listed along with the estimated size of their reserves (in billions of barrels):

1. Venezuela – 303.8 billion barrels
2. Saudi Arabia – 267 billion barrels
3. Canada – 170.5 billion barrels
4. Iran – 155.6 billion barrels
5. Iraq – 145 billion barrels
6. Kuwait – 101.5 billion barrels
7. United Arab Emirates – 97.8 billion barrels
8. Russia – 80 billion barrels
9. Libya – 48.4 billion barrels
10. Nigeria – 37.1 billion barrels
11. Kazakhstan – 30 billion barrels
12. United States – 35 billion barrels
13. China – 25.6 billion barrels
14. Brazil – 13 billion barrels
15. Qatar – 25.2 billion barrels
16. Mexico – 7.7 billion barrels
17. Angola – 8.4 billion barrels
18. Algeria – 12.2 billion barrels
19. Ecuador – 8.3 billion barrels
20. Norway – 8.1 billion barrels

These figures can vary based on new discoveries and changes in technology and economics affecting the viability of extraction.

Q: If all the oil in the world is burned, what amount of CO₂ is released from that ?

A: To estimate the amount of CO₂ released from burning all the world’s oil reserves, we can follow these steps:

1. Determine the total amount of oil reserves: Sum the proven oil reserves from the provided data.
2. Calculate the amount of CO₂ produced per barrel of oil: Use the average emission factor for crude oil combustion.

Step 1: Total Oil Reserves

The total proven oil reserves from the list provided sum up to:

303.8 + 267 + 170.5 + 155.6 + 145 + 101.5 + 97.8 + 80 + 48.4 + 37.1 + 30 + 35 + 25.6 + 13 + 25.2 + 7.7 + 8.4 + 12.2 + 8.3 + 8.1 = 1,581.2 billion barrels

Step 2: CO₂ Emission Factor

The average emission factor for crude oil combustion is about 0.43 metric tons of CO₂ per barrel of oil.

Calculation:

Total CO₂ emissions = Total oil reserves times x CO₂ emission factor

Total CO₂ emissions = 1,581.2 billion barrels x 0.43 metric tons of CO₂/barrel

Total CO₂ emissions = 680.916 billion metric tons of CO₂

Therefore, burning all the proven oil reserves in the world would release approximately 680.92 billion metric tons of CO₂ into the atmosphere.

Q: How much estimated Oxygen is present in the earth atmosphere?

A: The Earth’s atmosphere has an estimated total mass of about 5.15 × 10^18 kg. Oxygen makes up approximately 21% of the atmosphere by volume, which translates to about 23% by mass because oxygen molecules (O₂) are heavier than the average air molecule.

To find the total mass of oxygen in the atmosphere:

Total mass of the atmosphere = 5.15 x 10¹⁸ Kg
Percentage of oxygen by mass = 23% = 0.23

Mass of oxygen in the atmosphere = 0.23 x 5.15 x 10¹⁸ Kg

Mass of oxygen in the atmosphere approx 1.185 x 10¹⁸ Kg

Therefore, the estimated mass of oxygen present in the Earth’s atmosphere is approximately 1.185 × 10^18 kg.

Q: 680.92 billion metric tons of CO2 is what percentage of 1.185 × 10^18 kg ?

A: 680.92 billion metric tons of CO₂ is approximately 0.0574% of the total estimated mass of oxygen in the Earth’s atmosphere.

---

So 0.0574% change in the percentage of oxygen it seems is very bad for our planet and environment.

Very interesting!
