If the Earth's atmosphere is warming it has to expand. Can we measure an increasing thickness of the troposphere?

  • $\begingroup$ A great question. I think the answer is yes, but I am not familiar enough with the research. $\endgroup$ Dec 16, 2021 at 7:47
  • $\begingroup$ Has some interesting overlap to this other question posed this week: Is Global Mean Surface Atmosphere Pressure changed long-term by global warming? $\endgroup$ Dec 16, 2021 at 7:48

    $\begingroup$ As the troposphere height significantly increases from poles to the equator, why it should not have the mean increase with raising global mean temperature ? $\endgroup$

  • $\begingroup$ Doesn't the troposphere expand in summer and retract in winter? I guess that the troposphere's height mostly depends on your local sea level temperature. So yes, if it's warmer it should be higher. Perhaps one might rephrase the question to "how high is the troposphere at which temperature". $\endgroup$

    $\begingroup$ @Giovanni it is only summer on half the planet at any given time so only the average temperature comes into play here i think. $\endgroup$ Dec 17, 2021 at 6:56
