Can some only explain this model on greenhouse gases and global warming

I think I could describe it a bit for you. Fossil fuels, labeled where you see the grass, is because fossil fuels are found underground. These fuels are burned in the factory, and large amounts of carbon dioxide are released into the atmosphere. There are many different colored dots in that atmosphere. There is water vapor, infrared radiation, and solar radiation. The infrared and solar radiation is coming from the sun. In most cases, this radiation would eventually radiate out back to space, but in this case the carbon dioxide is filling the air and acting as a blanket, keeping a lot of it in so that the atmosphere is heating up. This is called the Greenhouse Effect. You also see that carbon dioxide absorbs infrared radiation and re emits it. Now, if you are familiar with the process called photosynthesis, you know that plants take in carbon dioxide to make oxygen, so some of the CO2 is being taken in there. You must also know that water, in this case the ocean presumably, takes in a lot of CO2, and the excess in CO2 is causing the oceans to warm.

Concluding Statement:

This would require further research, but I have given you the extent of my knowledge on the subject and really hope that helps.
