Carbon dioxide is removed from the atmosphere primarily throughphotosynthesisand enters theterrestrial and oceanic biospheres. Carbon dioxide alsodissolvesdirectly from the atmosphere into bodies of water (ocean, lakes, etc.), as well as dissolves inprecipitationas raindrops fall through the atmosphere. ...
Plant respiration represents approximately half (60 PgC/year) of the CO that is returned to the atmosphere in the 2 terrestrial portion of the carbon cycle. Litterfall: In addition to the death of whole plants, living plants also shed some portion of their leaves, roots and branches each ...
We always emit carbon through our activities. Our goal is that for each gram of carbon we emit into the atmosphere, we make sure we extract the most value from it as possible.Being carbon-efficient means to minimize the amount of carbon emitted per unit of work....
The news is also ___ by the latest data from the Amazon rainforest. This, one of the world’s largest woodlands, has acted ___ as an absorbing sponge (海绵)for CO2 by removing it from the atmosphere through photo-synthesis. Researchers at Brazil’s National Institute for Space Research...
Covering 71 percent of Earth's surface, the oceans play an essential role in maintaining the conditions for human existence on land, moderatingtemperature by the absorption of heat and carbon dioxide, and giving pure water back to the atmosphere through evaporation. ...
In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping. According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is...
During the inland water carbon transport processes, about 0.020 ± 0.010 PgC yr−1 of carbon is buried in aquatic sediments, and 0.062 ± 0.030 PgC yr−1 is returned to the atmosphere, and the remainder of 0.038 ± 0.019 PgC yr−1 is ...
Net bioaccumulation depends upon the balance of CO2 fixed from the atmosphere by phototrophs and CO2 returned to the atmosphere by respiration, and is influenced by a wide range of physical and biogeochemical processes. Recent work on the Greenland Ice Sheet suggests that carbon fixation exceeds ...
The initial–final mass relation (IFMR) links the birth mass of a star to the mass of the compact remnant left at its death. While the relevance of the IFMR across astrophysics is universally acknowledged, not all of its fine details have yet been resolved. A new analysis of a few car...
(Fig.5b). Similar to the period from years 1–140, the injected energy is partially transferred to the deep ocean and partially returned to the TOA. With higherγvalues, more energy is transferred to the deep ocean, resulting in lower efficiency in driving changes in theΔT(Eqs.2and3and...
