How is the greenhouse effect produced?

Answer 1

Technically ANY and all human activity causes the production of CO2. When you breathe you produce this gas. The MAJOR producers of greenhouse gas (of which man's total production is small) include the heating and cooling of homes and buildings partly through the generation of electricity (roughly 50% of our production), then Transportation (roughly 30%). The remaining 20% is spread around pretty wide. From the creation of food and medicine to using the internet.

Any combustion of fossil fuels (coal, oil and natural gas) releases additional carbon dioxide into the atmosphere, contributing to the enhanced greenhouse effect. Some greenhouse activities are driving cars and industry. Although there are many, many more.

Answer 2

Carbon dioxide (CO2) is produced mainly in the burning of fossil fuels such as coal, oil and gas in industry, in electricity generation, in transport and for heating purposes. In the incineration of waste, a great deal of carbon dioxide is released as well. Methane (CH4) is released mainly in cattle farming (digestive processes and manure), in waste treatment (fermentation on landfills), through leaks in the distribution of natural gas and in combustion processes. Laughing gas or nitrous oxide (N2O) is released especially in the burning of fossil fuels (mainly in traffic), in a number of processes in the chemical industry and in agriculture. CFCs and similar substances, and their substitute products (HCFCs and PFC's) are used chiefly as refrigerants, as propellants in aerosols and in the production of foam plastic.

Answer 3

The popular view is that the atmosphere has some sort of layer of carbon dioxide "up there" that reflects heat back down to Earth rather than letting it escape to space. That would be like the glass on a greenhouse trapping warm air in while letting the sunlight through to increase the heat. In a greenhouse the sunlight warms the benches and floor, he warm objects heat the air, the air is trapped by the double layer of insulating glass.

It does not happen that way.

Sunlight comes in and warms the Earth's surface. It warms the gases in the air too, at least some of them with a bond size that gets excited by sunlight. These special gases are greenhouse gases (carbon dioxide, methane, water vapour and a few others). They are mixed evenly through all of the atmosphere (not in layer). When the gases are warm they share their heat with all their gas molecule neighbour and heat the atmosphere generally.

The effect i more like wet sand in a microwave. Microwaves do not heat sand. They do heat water. When you microwave wet sand, the water heats up - might even turn to steam. The hot water warms the sand.
