Age: 15

Country: N/A
Date: 2000-2001
Question:
Is it possible that over the years, humans have effected the atmosphere that suurounds us with all of their pollutants and other technology. As a result of this could the atmospheric pressure ever change? Would it change that much that we would be affected by it?

Replies:
Andrew,

Atmospheric pressure varies significantly on the short term with changes in air masses, low and high pressure systems, etc. It is unlikely that man has had any measurable effect on average atmospheric pressure through his activities.
