Based on the table below, modern humans (homo sapiens sapiens) have been around for what percentage of Earth's history?What is the percentage of CO2 in the atmosphere and what is the percentage of dissolved CO2 in the oceans?What percentage of the world...
A New Definition of the Virtual Temperature, Valid for the Atmosphere ... In speleological environments, partial pressures of carbon dioxide (co2) are often large enough to affect overall air density. Excluding this gas when defining the gas constant for air, a new definition is proposed for th...

Concerns on rising concentrations of CO2in the atmosphere and global warming have increased in recent years. Numerous environmental studies analyze the trends in CO2emissions and their main drivers. In this paper we focus on the dynamics of the carbonization effect as a driving force for CO2...
Note that the negative values do not represent a negative absolute pressure. A gas having a negative pressure relative to the atmosphere is called vacuum. By definition there are four levels of vacuum, depending on the size of the negative relative pressure: rough vacuum fine vacuum high vacuum...
