In my world, the sky is getting taller, as it heats up. Climate change: Lowest level of the atmosphere growing ... newscientist.com The lowest level of the atmosphere, called the troposphere, has been growing warmer and gaining thickness at a rate of 53 metres per decade since 2000 By Chen Ly 5 November 2021 The orange-coloured troposphere, the lowest and densest portion of Earth’s atmosphere, ends at the tropopause Ron Garan/NASA The tropopause – a boundary within the atmosphere – is increasing in altitude due to climate change. The lowest layer of the atmosphere where we live and breathe is called the troposphere, and it is separated from the stratosphere above – which is where the protective ozone layer sits – by the tropopause. There is natural variation in the altitude of the tropopause: it lies roughly 18 kilometres above sea level at the equator and around 10 kilometres above sea level at the poles. But Jane Liu at the University of Toronto in Canada and her colleagues have found that its altitude across the northern hemisphere has risen in recent decades. The researchers analysed atmospheric data such as pressure, temperature and humidity collected by weather balloons, and also used data from GPS satellites, to track changes in the tropopause between 1980 and 2020. The team focused specifically on the northern hemisphere, where changes to tropopause height are thought to have been larger than in the southern hemisphere. The team found that the altitude of the tropopause in the northern hemisphere has steadily increased between 1980 and 2020. Between 2001 and 2020, the altitude increased at a rate of around 53.3 metres per decade, which is a slightly higher rate of increase than between 1980 and 2000....
