No Comments on Atmospheric Carbon Dioxide Reached the Highest Levels in 800,000 years To limit global warming to 1.5-2 °C by 2100 (relative to pre-industrial temperatures), we'd need an urgent and rapid reduction in global greenhouse gas emissions. Image: PX Here According...

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...
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...
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...
(Fig.2), but the information content decreases within the first five to ten mantissa bits for most variables, such that many trailing mantissa bits do not contain real information. Exceptions occur for variables like carbon dioxide (CO2) with mixing ratios varying in a very limited range of 0...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
Two in particular, carbon dioxide and ozone, can have a large impact on atmospheric processes. Another gas, water vapour, also exists in small amounts. It varies in concentration from being almost non-existent over desert regions to about 4% over the oceans. Water vapour is important to ...
It consists of a telescope with diameter of 210 mm as transmitter and receiver, a 35 W Deuterium lamp as light source and a spectro- graph. Calibration of the DOAS system was performed individually by inserting a cell with quartz glass windows into the optical path between the light ...
[17] If the EDC CO2 record is representative of atmo- spheric pCO2, the fact that the iron flux change precedes the CO2 change indicates that this parameter may contribute to the glacial/interglacial carbon dioxide changes. It is also evident that the subsequent sharp increase in CO2 levels ...
