Which most likely was persia’s most valuable asset?

Oil is the main resource that Persia (Iran) has and until 2006 it was estimated that it was the fourth largest producer of oil in the world.

Taking into account that the world is still very dependent on this fossil fuel, it makes this resource of great importance for this region in its relationship with neighboring countries.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
