It would be a fairly simple science to determine how much fossil fuel was produced and sold each year. A look at the last 200 years is enough.
If you consider it possible (there are studies and scientists who speak for and against it, and money and purchase are available on both sides) that the resulting CO2 makes an additional contribution to the existing global warming (
@Pat Hartman Of course not alone and 1:1), then you can draw conclusions from it.
There are many more aspects that could be considered (or denied):
- the role of modern agriculture - humus degradation or creation
- the destruction of peatlands, which are enormous C reservoirs
- the burning of forests in order to generate agricultural land or building land for speculative real estate.
- Sealing of surfaces: A concrete surface becomes hotter than a meadow and radiates more heat. It does not absorb any water and cannot subsequently cool through the evaporation of the water it absorbs.
- Overuse of areas: Where there used to be forests and grassland, today there are often steppes and deserts, man-made.
People change their environment: Egypt, as an ancient advanced civilization, was known as an important grain producer. An advanced culture can only develop and sustain itself if nutrition is not a serious problem. Today Egypt is a large importer of grain for various reasons and, for example, is very affected by the war in Ukraine and a lack of deliveries.
Carthage (modern-day Tunisia) was also a granary for the Roman Empire.
If you look at things like this in fast motion, they can become clearer to some people.
If you look at Earth from space at night, you can see almost all of the coastlines and most of the continents illuminated. This is available for free? How simple do you have to think to believe something like that?
