What is the gas that is most responsible for creating a greenhouse effect on the Earth and Venus?

Answer 1

Carbon dioxide is usually blamed the most, since its more abundant on both Earth and Venus.
But on Earth particularly, methane contributes about 20 times the greenhouse effect of the same amount of CO2.

Answer 2

The greenhouse gas most responsible for global warming here on Earth is H2O. Carbon Dioxide is pretty minor. Humans are responsible for only about 4% - 5% of the total yearly carbon output. Livestock is about 16% - 18% yearly. That means that the Earth puts out about 80% yearly with out our help. Without the mammals, the Earth still makes four times what we create. That means that the Earth has a way of dealing with it. Global Warming is nothing to worry about, because we cant do anything about it. It is a normal process that the Earth goes through.

Answer 3

It is not CO2 as the plants have done there job of recycling our oxygen.
It is not methane. There are 2 major problems of how the environmentalist measured methane in the first place. It looks like faked data. The reason is methane is very light so if u intend to measure it ,u should look at 55 miles up and the methane is not there. so where is it. if there is no green house gas there is no global warming.

Answer 4
