These lamps are supposedly «more powerful than a forest» when it comes to
removing atmospheric carbon.
But now, new research shows that we may be able to rely - at least in part - on nature alone, which has its own methods for
removing atmospheric carbon.
The Amazon rainforest normally acts as a carbon sink,
removing atmospheric carbon dioxide and storing it.
As for the paper's conclusion that
removing atmospheric carbon is necessary in order to achieve the 2 ˚C target, climate scientist Richard Moss of the Pacific Northwest National Laboratory's Joint Global Change Research Institute in College Park, Maryland, says that's a nearly impossible goal «with what we know about today.»
The ISIS (In - Situ Iron Studies) Consortium is a group of institutions and scientists who are motivated to answer the unknowns regarding the role of iron in regulating the ocean's capacity to
remove atmospheric carbon dioxide.
A second BCDR strategy is forestry - based sequestration, which
removes atmospheric carbon and stores it in forest biomass by increasing forest area and / or carbon density.

Those techniques have led to everything from the development of catalysts that
remove poisonous
carbon monoxide from car exhaust to the understanding of how ice crystals in stratospheric clouds supercharge
atmospheric chlorine's ability to destroy the planet's protective ozone layer.
The living things are such a powerful factor in the Earth's
carbon cycle that they shift, they can
remove and replenish several percentage of the Earth's entire
atmospheric CO2 during the course of this six - month up and downs, six months up and six months down cycle.
The melting of the Greenland ice sheet trigger accelerated sea level rise, a die back of the Amazon rainforest
removes a crucial
atmospheric carbon sink, and an alteration of the ocean conveyor belt shuts down the Atlantic Gulf stream.
Consequently
atmospheric concentrations of
carbon dioxide could become substantially elevated before the ocean is able to
remove this added
carbon dioxide.
Consequently
atmospheric concentrations of
carbon dioxide could become substantially elevated before the ocean is able to
remove this added
carbon dioxide.
There is only one viable way to
remove carbon from the atmosphere (over millenia - scale timeframes), which is to covert
atmospheric CO2 to a stable solid material, such as charcoal or calcium carbonate, and bury it.
Not only are they one of the most important
carbon sinks, storing more
carbon than both the atmosphere and the world's oil reserves, they also constantly
remove carbon from the atmosphere through photosynthesis, which converts
atmospheric carbon to organic matter.
Like other tiny
atmospheric particles called aerosols, black
carbon (BC) has a short lifetime in the atmosphere of about a week because it is
removed by rain or snow.
Thus if it is decided in the future that CO2 must be extracted from the air and
removed from the
carbon cycle (e.g., by storing it underground or in carbonate bricks), the impact on
atmospheric CO2 amount will diminish in time.
Opening with a biographical sketch of Broecker — who, we learn, was born to an Evangelical suburban Chicago family, and initially drifted into his scientific vocation via a summer job in a radiocarbon dating lab — the book explains the currently - accepted Milankovitch theory of Ice Age glaciation; proceeds to an account of the Dr. David Keeling's measurements
atmospheric CO2; continues with a summary of research work on glacial ice cores, sediments, and fossil pollen from around the world showing startlingly abrupt prehistoric climate changes; and moves on to the possible consequences of continued warming, closing with an account of the prospects of
removing carbon dioxide from the atmosphere.
«If a lot of
atmospheric carbon dioxide is absorbed and
removed from the atmosphere by algae and then transported to the deep ocean, then the atmosphere should theoretically stop warming and get cooler.»
This study finds that the recent swift increase in
atmospheric CO2 is due to faster economic growth coupled with a halt in
carbon intensity reductions, in addition to natural sinks
removing a smaller proportion of emissions from the air.
Having retrieved the original article (Canadell et al., 2007, PNAS online) it's written (p. 3) that 65 + / -16 % of... d ² CO2 / dt ² (translation of «increase of
atmospheric CO2 growth rate») is attributed to «the increase in the global economy», the remaining 35 + / -16 % being attributed to «the increase in
carbon intensity in the global economy» and 18 + / -15 % to «the decrease in the efficiency of the lands and ocean sinks in
removing anthropogenic CO2».
