carbon dioxide (for example,
by running cars on gasoline) faster than plants can
absorb it, which makes the Earth warmer — and much faster than has happened naturally in the past.

carbon absorbed by the world's tropical forests and the amounts of greenhouse gas emissions created

absorbed by water vapor and
carbon dioxide is shared with all the nitrogen, oxygen and argon, because the latter molecules are always bumping into water vapor and
carbon dioxide as they mix in the atmosphere.

carbon monoxide, methane, and
carbon dioxide.

carbon fiber skeleton covered with a latex membrane that pacifies gusts
by acting as a shock
absorber.
Instead of dissipating into space, the infrared radiation that is
absorbed by atmospheric water vapor or
carbon dioxide produces heating, which in turn makes the earths surface warmer.

carbon dioxide — do
absorb a portion of the infrared heat radiated
by the earth's surface, thereby preventing it from reaching space.

by absorbing more
carbon dioxide are at higher risk of death in multiple ways.
Soot particles, also known as black
carbon aerosols, affect climate
by absorbing sunlight, which warms the surrounding air and limits the amount of solar radiation that reaches the ground.
If it is replaced
by other farmers boosting their yields more than they otherwise would, spurred
by higher prices, you may get a benefit because higher yields
absorb more
carbon (but it comes at some greenhouse gas costs from fertilizer use and the like).
Because
carbon in the air is
absorbed by trees,
carbon - 14 levels in tree rings actually reflect solar activity and unusual solar events in the past.
Acidity may impair movement Previous research has shown that when
carbon dioxide is
absorbed by the ocean and it becomes more acidic, concentrations of calcium carbonate drop, and that hurts shellfish and corals, which use calcium carbonate to build shells and skeletons.
When
carbon dioxide, CO2, from the atmosphere is
absorbed by the ocean, it forms carbonic acid (the same thing that makes soda fizz), making the ocean more acidic and decreasing the ocean's pH. This increase in acidity makes it more difficult for many marine organisms to grow their shells and skeletons, and threatens coral reefs the world over.
