The relation between the two is the “equivalent” in “CO2e”. It does not imply that there is or is no CO2 in a particular GHG (green house gas) but that it allegedly excerpts the same level of energy when released in the atmosphere. It is not a physical product. It is a unit....
What is CO2? The role of CO2 in causing global warming is often discussed, but CO2 also has adverse effects on the human body. If the concentration of CO2 in a room rises too high, it will cause headaches, drowsiness, and fatigue. If it exceeds 6000ppm,
told"CBS Mornings Plus"on Wednesday there is "excellent, solid data going back 75 years, showing that fluoride is both safe and it's extremely effective at decreasing dental decay, that is, cavities, by strengthening the enamel of our teeth." ...
Is Our Number Up - What Does CO2 at 400 ppm Mean?moses seenarine
CO2 is a global warming gas because it causes the atmosphere to retain heat. The concentration of CO2 in recent years has not only been rising but also accelerating at an alarming rate. In 2012, average global CO2 levels exceeded 400 parts per million (ppm) for the first time in recorded...

CO2 currently consists of around 400 ppm of the atmosphere according to scientific studies. 400 ppm equates to 0.04% of the atmosphere but you are representing it as being eight times higher at .33%. How'd you come up with your numbers? I can't find anywhere in science where CO2 ...

print speed can be crucial, depending on your printing needs. if you frequently print large volumes or need quick turnaround times, a printer with high-speed printing capabilities would be beneficial. print speed is usually measured in pages per minute (ppm). however, keep in mind that print...
(δ11B) proxy range from ~600 to 2500 ppm and suggest that CO2was the major driver of long-term climate change during the Cenozoic19,20. The warmest sustained temperatures were reached during the Early Eocene Climatic Optimum (EECO; ~53–50 Ma) (Fig.1), with ocean bottom water ...
