Humans create greenhouse gases by burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2). Cattle rearing and rice paddy fields release methane (CH4), another greenhouse gas.
Natural causes of greenhouse gases are volcano eruptions, and the rotting of any organic matter (trees, plants and animals).
No, there is a natural greenhouse effect which has kept the earth warm for millions of years. By burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, humans are causing the enhanced (or accelerated) greenhouse effect which is causing global warming.
The difference is the same as in other contexts.* "Artificial" means that something was created by humans. * "Natural" means that it was NOT created by humans.
Yes ! Since the industrial revolution - we have been pumping billions of tonnes of pollutants into the atmosphere. Atmospheric pollution disrupts the Earth's natural heating & cooling cycle,
We don't want to stop the natural greenhouse effect, which keeps the earth warm enough for life. We can stop the enhanced (or accelerated) greenhouse effect which is causing global warming. But we have to act now and seriously, to move to renewable energy, stop burning fossil fuels (coal, oil and natural gas), and replant billions of trees.
We can't stop the natural greenhouse effect, and we don't want to! Without the natural greenhouse effect, temperatures on the Earth's surface would be far too cold for humans to survive.However, the enhanced (or accelerated) greenhouse effect which is causing global warming can only be stopped by changing to renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, and biofuel) and stopping burning fossil fuels (coal, oil and natural gas).
Changes that happen without no help from humans they happen completely natural.

Tornadoes are a natural phenomenon. They cannot be created by humans.
Erm..they r and there not coz some r natural and sum r coz of humans
The Greenhouse effect started long before humans were on Earth. The Greenhouse effect is only intensified by the presence of humans.
I Belive that humans were created in the form of apes.

The greenhouse effect is the natural process by which greenhouse gases keep the earth's temperature at a comfortable level suitable for human existence. The enhanced greenhouse effect is the increase in greenhouse gases that is leading to global warming. The term "enhanced greenhouse effect" is also referred to as the "anthropogenic greenhouse effect" and is the idea that humans may have an effect on global climate. It is also referred to as the "runaway greenhouse effect".
It is created by nature, not by humans.
