Data has been measured at Mauna Loa Observatory, Hawaii as it constitutes the longest record of direct carbon dioxide measurements in the atmosphere. CO₂ expressed as a mole fraction in dry air, micromol/mol, abbreviated as ppm. Open this statistic in... Spanish Citation formats Citation...
Aleurites montana exhibits a strongly CO2-dependent photosynthesis which partially explains the observed stimulatory effect of 700 ppm CO2 on growth of the plant. In control plants grown in normal air, photorespiration measured simultaneously with photosynthesis via the uptake of l80 2 in the light, ...
Correlations between rising CO2 levels, rising ocean temperature and the biological responses of reefs are therefore known in detail, providing a particularly well-grounded basis for future prediction. The more recently recognised effects of atmospheric CO2 on ocean acidification will have even more ...
Today, ppm is an essential tool in many scientific disciplines. It allows researchers to quantify the concentration of substances in a solution or a mixture with great precision. Whether it’s monitoring pollutants in the air, analyzing water samples for causes and effects of water pollution, or...

These could be the highest CO2 levels in our atmosphere in more than 3 million years Another climate record was set in May of this year. Carbon dioxide levels in the atmosphere reached a new maximum, topping out at their highest concentration seen in all ...
I have defined an air inlet (velocity inlet), a human CO2 emission rate (mass flow inlet) and an extractor (pressure outlet). I have created a passive scalar (COtwo) and defined a passive scalar value of 1 in the human boundary and a value of 0 in the air inlet. In Regions I ...
Although capture technologies show promise, pulling CO2 out of the air is unlikely to reduce greenhouse gas concentrations soon
These days, some parents and teachers discuss if they need to install(安装)this kind of machine in classrooms. They think it's more important for students to get fresh air. Kids get sick easily because of the air pollution. (2)___"Our school bought air cleaners last...
