根据第三段中的All of this extra carbon needs to go somewhere.So far,land plants and the ocean have taken up about 55 percent of it,(所有这些多余的碳都需要去某个地方。到目前为止,陆地植物和海洋已经占据了其中的55%)可知,陆地植物和海洋吸收了55%的多余的碳,由此可以推断出,超过一半的多余的碳被...
However, the mass burning of fossil fuels, and deforestation over the past two centuries has released trillions of tons of CO₂ into the atmosphere. This has caused atmospheric CO₂ levels to climb more than 50 percent above pre-industrial levels. Impacts of high atmospheric greenhouse gas ...
Plants and currents in the ocean absorb large amounts of CO2 from the atmosphere. The sea is estimated to have drawn in about 30 percent of carbon emissions since the Industrial Revolution. But carbon emissions also make oceans more acidic (酸性的). It can hurt coral reefs, which are sensit...

In 2019, about 43.1 billion tons of CO2 from human activities were emitted into the atmosphere. This was an all time high, breaking the previous record from 2018. The emissions could form a giant “CO2 cube” measuring 30 km on each side. CO2-emissions NOT going down Global emissions of...
Carbon dioxide, also known as CO2, exists in the atmosphere at a concentration of 0.033 percent. The chemical reactions that produce CO2 include animal respiration and the combustion of hydrocarbons. Carbon dioxide does not normally exhibit a liquid state; it converts directly from solid form to ...
ranks the largest in southern China. The drainage area of the Pearl River has a sub-tropical climate, with a long summer and a short winter with annual rainfall of 1470 mm. Eighty percent of the river discharge takes place in the wet season from April to September (PRWRC/PRRCC, 1991)....
37 which compares modeled pCO2 estimates using PHREEQC to direct measurements, they conclude that although mole change balance percent errors are high PHREEQC still provides a good estimate of pCO2 using pH, temperature, and alkalinity. So, we have decided to exclude mole change balance percent ...
such a push could achieve an 80 percent or greater reduction in carbon emissions on the 2-3 decade timescale with net negative carbon emissions by mid Century. For cities on the coast, choosing whether or not to support such a set of actions is ultimately an existential one.”–RobertScribb...
