The graph above shows the recent monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii in the last five years. It is published by the National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory Global Monitoring Division.The last four complete years of the...

Climate change mitigation demands reduced anthropogenic emissions of greenhouse gases (GHGs) and effective removal of excess carbon dioxide (CO2) and methane (CH4) from the atmosphere. Shallow-water coastal ecosystems can absorb and store large amounts of carbon from the atmosphere through vegetation b...
Carbon capture isn't new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature...
2.2.4 Other Non-formaldehyde carbon A number of other carbon sources not specifically mentioned in the categories above have been considered as to potential ilnpact on the system. 'carbon dioxide, being present at concentrations nearly 106 higher than formaldehyde in the a'bnosphere, is naturally...
According to the US Geological Survey (USGS), the world's volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Des...
摘要: Some aspects of the formation, control and dispersion of atmospheric pollution from fossil fuels are considered, especially the variation of concentration in time and space with weather and topographothery, the summation and interaction of many pollutants from various sources, and the large spa...
17confirmed that the increased iron supply would promote the fixation of macronutrients such as nitrogen and phosphorus, so as to increase primary productivity18and decrease carbon dioxide concentration19. Besides, iron is critical to the human body for Fe(II)-bearing haemoglobin in the blood, Fe(...
I’ve usually accepted the premise that increasing atmospheric carbon dioxide concentrations are due to the burning of fossil fuels by humans. After all, human emissions average around twice that which is needed to explain the observed rate of increase in the atmosphere. In other words, mankind ...
