This is happening because humans have been producing
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.

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 — do
absorb a portion of the infrared heat radiated

by absorbing more
carbon dioxide are at higher risk of death in multiple ways.
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.
Over the last few centuries, the ocean has
absorbed huge amounts of the
carbon dioxide spewed into the atmosphere
by human activities, such as burning fossil fuels.

absorb carbon dioxide and store or «fix» it in plants, according to the research — a study led
by scientists at the University of Montana and published in the journal Science.
Critics argue that albedo modification and other «geoengineering» schemes are risky and would discourage nations from trying to reduce their emissions of
carbon dioxide, the heat - trapping gas that comes from the burning of fossil fuels and that is causing global warming
by absorbing increasing amounts of energy from sunlight.
One of the many downsides of too much
carbon dioxide in the atmosphere is what happens when some of that CO2 is
absorbed by the oceans.
It destroys the rain forest habitat, fails to alleviate poverty, and contributes to global warming
by eliminating trees that would
absorb and store
carbon dioxide.
(The ocean currently
absorbs roughly half of the greenhouse gases, primarily
carbon dioxide, that are released
by human activity.)
The OCO would have helped scientists monitor global warming
by measuring how much
carbon dioxide was in a given part of the atmosphere and where it was being
absorbed.
Carbon - 14 can combine with oxygen in the atmosphere to create
carbon dioxide, which is then
absorbed by plants and makes its way through the food chain.

absorb carbon dioxide.
Oceans have
absorbed about one - third of the excess

(Note vast areas of the high latitude oceans were covered
by ice, during the coldest period and could hence no longer
absorb carbon dioxide.)
Basically, although the gas is indeed easily
