7. Anthropogenically-Driven Atmopheric Greenhouse Gas (Percentage by Gas Species) Change, 2019 to 2030

The anthropogenic contribution to greenhouse gases, including water vapor, is primarily indirect. Below is the breakdown of human-caused changes in greenhouse gases from 2019 to 2030:

1. Carbon Dioxide (CO₂ :

2019: ~38 gigatons of CO₂

2030 (projected): ~39 gigatons of CO₂

Percentage Increase:

The anthropogenic contribution to CO₂ emissions is direct, largely from burning fossil fuels, deforestation, and industrial processes.


2. Methane (CH₄ :

2019: ~9.5 gigatons of CO₂-equivalent (CH₄

2030 (projected): ~10.5 gigatons of CO₂-equivalent (CH₄

Percentage Increase:

Human activities such as agriculture (especially livestock), fossil fuel extraction, and waste management are the major contributors to methane emissions.


3. Nitrous Oxide (N₂O):

2019: ~3 gigatons of CO₂-equivalent (N₂O)

2030 (projected): ~3.5 gigatons of CO₂-equivalent (N₂O)

Percentage Increase:

Nitrous oxide emissions come from agricultural practices, particularly the use of synthetic fertilizers, as well as some industrial processes.


4. Fluorinated Gases:

2019: ~1.5 gigatons of CO₂-equivalent (Fluorinated gases)

2030 (projected): ~2 gigatons of CO₂-equivalent (Fluorinated gases)

Percentage Increase:

Fluorinated gases are synthetic gases used in refrigeration, air conditioning, and industrial processes. These gases have a high global warming potential, and their emissions are entirely anthropogenic.


5. Water Vapor (Indirect Contribution from Anthropogenic Activities):

Water vapor in the atmosphere is indirectly influenced by human activities through the warming of the planet caused by greenhouse gas emissions. As the atmosphere warms, it can hold more moisture.

2019: ~12,900 gigatons (baseline)

2030: ~13,803 gigatons (with a 1°C temperature rise)

Percentage Increase (due to anthropogenic warming):

The increase in water vapor is entirely a feedback mechanism, driven by higher temperatures from anthropogenic greenhouse gas emissions.



---

Summary of Anthropogenic Contributions (2019–2030):

Carbon Dioxide (CO₂ : ~2.6% increase

Methane (CH₄ : ~10.5% increase

Nitrous Oxide (N₂O): ~16.7% increase

Fluorinated Gases: ~33.3% increase

Water Vapor (Indirect feedback due to warming): ~7% increase


These figures reflect the human impact on each greenhouse gas, either directly through emissions (CO₂, CH₄, N₂O, fluorinated gases) or indirectly through the feedback effect of warming (water vapor).
