Carbon dioxide in 2014 made up 0.04% of the atmosphere. This figure is rising every year.
A:In a natural balance, plants absorb as much carbon dioxide (CO2) as animals exhale, keeping the concentration of atmospheric carbon dioxide at the long-term average of around 260 to 280 parts per million (ppm). Human activities have increased this level to 380 ppm since the beginning of the Industrial Revolution, and rising fat. This itself is evidence that plants simply can not absorb the additional carbon dioxide load in the atmosphere. Moreover, our continuing destruction of forests actually reduces the ability of plants to absorb carbon dioxide, and is one important reason for the rising CO2 levels.
Carbon dioxide is a naturally occurring greenhouse gas. At present concentrations, it helps maintain global temperatures at a level that is comfortable for humans and other animals that have adapted to the present climate. Increasing the amount of carbon dioxide in the atmosphere can result in global warming, by trapping more heat. This occurs when humans burn fossil fuels, manufacture cement of destroy forests.
When greenhouse gases like carbon dioxide increase in the atmosphere then the temperature rises. Greenhouse gases capture heat rising from the surface of the earth and prevent it escaping to space.

The carbon Dioxide levels in the Earth's atmosphere are rising.
Carbon dioxide (CO2) absorbs heat rising from the surface of the earth.
Cause/effect
It will rise. The temperature of the atmosphere is rising already because carbon dioxide is increasing due to human activity.

An ice age will put more carbon into the atmosphere. The increase in carbon captures the Sun's energy and the planet begins to warm.
