The mesosphere (/ ˈ m ɛ s ə s f ɪər, ˈ m ɛ z-, ˈ m iː s ə-,-z ə-/; [1] from Ancient Greek μέσος (mésos) 'middle' and -sphere) is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
As a result, the lower mantle's temperature gradient as a function of depth is approximately adiabatic. [1] Calculation of the geothermal gradient observed a decrease from 0.47 kelvins per kilometre (0.47 °C/km; 1.4 °F/mi) at the uppermost lower mantle to 0.24 kelvins per kilometre (0.24 °C/km; 0.70 °F/mi) at 2,600 kilometres (1,600 mi).

The mesopause is the point of minimum temperature at the boundary between the mesosphere and the thermosphere atmospheric regions. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesosphere is the coldest region on Earth with temperatures as low as -100 °C (-148 °F or 173 K). [1]
Green Day have taken lyrical aim at Elon Musk while performing in his home country of South Africa.. The band’s frontman Billie Joe Armstrong reportedly switched a line in their 2004 hit ...
It varies with the temperature and pressure of the parcel and is often in the range 3.6 to 9.2 °C/km (2 to 5 °F/1000 ft), as obtained from the International Civil Aviation Organization (ICAO). The environmental lapse rate is the decrease in temperature of air with altitude for a specific time and place (see below). It can be highly variable ...
The variation in temperature that occurs from the highs of the day to the cool of nights is called diurnal temperature variation. Temperature ranges can also be based on periods of a month or a year. The size of ground-level atmospheric temperature ranges depends on several factors, such as: Average air temperature; Average humidity
"The Fountain in the Park", also known as "While Strolling Through (or Thru') the Park One Day", is a song by Ed Haley, a member of the vaudeville act the Haley Brothers. [1] Some authors believe the song was written by Robert A. Keiser , to whom Haley dedicated the song.
Billy Bragg covered the song but altered the lyrics to make it a protest song dealing with the issues of 2017. Bragg sang lyrics such as "Accept it that soon you'll be drenched to the bone/For the climate is obviously changing," and "But the man in the White House says no one's to blame/For the times, they are a-changing back."
