carbon dioxide to cool Earth's warming environment
while releasing much of oxygen we breathe.

while alive, then carry the
carbon they've
absorbed down to the sea bottom when they die.
While this controls the amount of
carbon dioxide they're
absorbing, it has the added outcome of limiting the amount of water released into the air from plants.

carbon dioxide
absorbed by forests will count towards its overall emissions reductions, it is unclear whether they are permitted in its 2020 target.

carbon to
absorb offending odors
while others are scented — the latter may be offensive to cats.

Artist Statement «Trees
absorb carbon dioxide (CO2), removing and storing the
carbon while releasing the oxygen back into the air.
• albedo decreases as ice melts (ice is perhaps 80 % reflective,
while ocean albedo can be as low as 3.5 %) • increased water vapor in a warmer climate • warmer oceans
absorb less
carbon dioxide • warmer soils release
carbon dioxide and methane • plants in a hotter climate are darker
natural decay... and... forest fires... release... 439 gigatonnes of
carbon dioxide every year,
while new growth entirely counteracts this effect,
absorbing 450 gigatonnes per year.»
«For example, the natural decay of organic material in forests and grasslands and the action of forest fires results in the release of about 439 gigatonnes of
carbon dioxide every year,
while new growth entirely counteracts this effect,
absorbing 450 gigatonnes per year.»
It was
while pursuing the cause of ice ages that he discovered that water vapor, methane and
carbon dioxide
absorb infrared radiation.
While the 2030 target is explicit that
carbon dioxide
absorbed by forests will count towards its overall emissions reductions, it is unclear whether they are permitted in its 2020 target.
Alarmists demand that the US and other Western countries unilaterally decrease their
carbon dioxide emissions,
while allowing unlimited increase to China and all other countries, which already emit more than 70 % of
carbon dioxide and almost 100 % of other infrared -
absorbing gases and soot.How could this happen?
As to the absorption of long - wave radiation from the earth's surface,
while it may be true that
carbon dioxide and water together do
absorb certain frequency ranges of that radiation, I don't think that that matters a whole lot because most of the heat from the surface is transported to the top of the troposphere by conduction, convection and latent heat of vaporization of water during the day.
While coral reefs only cover 0.0025 percent of the oceanic floor, they generate half of Earth's oxygen and
absorb nearly one - third of the
carbon dioxide generated from burning fossil fuels.
In this graph, positive values mean that the land is a net
carbon sink (
absorbing CO2),
while negative values mean it is a net
carbon source (releasing CO2).
While methane doesn't stay in the atmosphere as long as
carbon dioxide, it
absorbs 84 times more heat, making it very harmful to the climate.
Because of its molecular structure,
carbon dioxide is a greenhouse gas, which means it allows visible light from the Sun to pass through the atmosphere
while absorbing and reemitting infrared energy, heating the Earth.
While the Indians aggressively pushed for REDD + + in negotiations and the Americans argued for an even broader approach to land use - based emissions including the recognition of
carbon absorbed by all land use change, African negotiators took a softer approach — pushing for REDD, but willing to take a rain check on AFOLU, even as the Common Market for Eastern and Southern Africa (COMESA) was promoting its «BioCarbon» initiative, which explicitly endorses credits from sustainable agriculture and forestry.
