#ClimateChange is expanding the #earth's lower atmosphere and it's not a good sign

@marciasekhose A new study shows the #earth’s atmosphere is expanding due to #climatechange. The study revealed that the tropopause which sits on top of the troposphere has been expanding upward at around 164 feet every decade since 1980.

@marciasekhose The findings of the study published in the journal Science Advances detail how #climatechange is causing these changes in the lowest layer of the #earth’s atmosphere.

@marciasekhose The tropopause is defined as the upper limit of the troposphere which is the lowest layer of the atmosphere. It also constitutes the boundary between the troposphere and the stratosphere.

@marciasekhose This is also where most of the atmospheric weather occurs, and the tropopause also expands and shrinks according to changing seasons.

But scientists discovered that this expansion rate is happening at an alarming rate.

@marciasekhose Scientists analysed data from 1980 to 2020 to examine how climate change is affecting tropopause. It analysed atmospheric data such as pressure, temperature and humidity along with GPS data.

@marciasekhose The results showed that due to the increasing quantities of greenhouse gases trapping more heat in the atmosphere, the tropopause is expanding even further.

@marciasekhose Specifically, there was an increase of around 164 feet per decade between 1980 and 200. This later increased to an average of 174 feet between 2001 and 2020. The study also revealed that 80% of the total increase in temperature was due to human activities.

@marciasekhose Although there is an increase in the expansion of the tropopause, there’s no conclusion yet on how exactly this would affect the climate or weather. But the study suggests this could lead to planes flying higher in the atmosphere to avoid turbulence.
