These results show significant variations in the CO2 mixing ratio in the atmosphere over the St. Petersburg region. The minimum value of this mixing ratio (373.1 ppm) was observed on April 27, 2011, and its maximum value (420.8 ppm) was observed on February 10, 2010. The typical seasonal ...

The current amount of CO2 present in the atmosphere today is 400 ppm. If CO2 is increasing at the rate of 1.3 ppm/year, how many years will it take for our CO2 concentration to become roughly double its current values? What would happen to regional temperatures ...
For environmental factors, the average and standard deviation during sleep were calculated for Ta [°C], Hc [%], Tr [°C], Tb [°C], CO2 [ppm], and Lx [lx] (see Glossary), with "Ave" and "SD" appended to the symbols, respectively. Typically, physiological metrics during sleep ...
Yep, a 15.27% (51ppm) increase in CO2 since 1979 and absolutely jack $hit warming to show for it. Thats 268 gigatonnes of CO2 all dressed up with nowhere to go. No wonder the “Bimbo for Climate Change” has ducked for cover.
The nominal composition (in weight %) of the alloy is: 6.2 Al, 0.05 C, 7.5 Co, 7.0 Cr, 0.16 Hf, 1.5 Mo, 3.0 Re, 6.5 Ta, 0.02 Ti, 5.0 W, and Ni as the balance. This alloy was melt-desulfurized to below 1 ppm sulfur. The specimen surface was polished prior to coating ...
