this is a tremendous and inspirential awe inspiring exhibition.Well worth a visit and best of all it was accessable ad free of charge. You must see it. Saw this in London and was bowled over - so pleased it's now in Birmingham so we can see it again and again. a b "Trends in Atmospheric Carbon Dioxide", Global Greenhouse Gas Reference Network, NOAA, 2019 , retrieved 2019-05-31 What a fantastic exhibition! I have been late for sooooo many meetings. Its lovely to have it right there in open view. I even (unusually) brought my teenage daughter into town just to look at it earlier in the year.Inspired use of public space:¬)Dawn

Came across it last night, my journey was suddenly curtailed, loved images and the facts which resonated in so may ways.Didn't do the work justice will take my sons there to see it again, loved the way it was so accessible and no grafitti.Thank you Birds Eye and Birmingham States, Robert J.; Gardner, Chester S.

Taken from all over the planet, the 160 photographs chosen for the exhibition tell a story about our changing planet and the need for sustainable development. A marvelous exhibition. Any images you see on web is no match for the real photos being exhibited. I've seen them in London, but still I can't tell how delighted I am to know that they've come to Birmingham, and immediately send messages to all my friends about the good news, so good it is. No residents of Birmingham should miss it. A real pity they are not going to stay for two years. creation of «Yann Arthus-Bertrand Photo », the official entity dedicated to his photographic work. It also aims to shed light on the part of his work never before revealed, a memoire of the time when photography was considered to be a tool for providing information rather than a true artistic medium.

Main article: Absorption (electromagnetic radiation) Rough plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation, including visible light.

Above this altitude lies the heterosphere, which includes the exosphere and most of the thermosphere. Here, the chemical composition varies with altitude. This is because the distance that particles can move without colliding with one another is large compared with the size of motions that cause mixing. This allows the gases to stratify by molecular weight, with the heavier ones, such as oxygen and nitrogen, present only near the bottom of the heterosphere. The upper part of the heterosphere is composed almost completely of hydrogen, the lightest element. [32]

The exosphere is the outermost layer of Earth's atmosphere (though it is so tenuous that some scientists consider it to be part of interplanetary space rather than part of the atmosphere). It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and interplanetary medium. The altitude of the exobase varies from about 500 kilometres (310mi; 1,600,000ft) to about 1,000 kilometres (620mi) in times of higher incoming solar radiation. [22] is below 100km (62mi; 330,000ft), the Kármán line. By international convention, this marks the beginning of space where human travelers are considered astronauts. Troposphere". Concise Encyclopedia of Science & Technology. McGraw-Hill. 1984. It contains about four-fifths of the mass of the whole atmosphere. The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere by mass. The concentration of water vapor (a greenhouse gas) varies significantly from around 10 ppm by mole fraction in the coldest portions of the atmosphere to as much as 5% by mole fraction in hot, humid air masses, and concentrations of other atmospheric gases are typically quoted in terms of dry air (without water vapor). [11] :8 The remaining gases are often referred to as trace gases, [12] among which are other greenhouse gases, principally carbon dioxide, methane, nitrous oxide, and ozone. Besides argon, already mentioned, other noble gases, neon, helium, krypton, and xenon are also present. Filtered air includes trace amounts of many other chemical compounds. Many substances of natural origin may be present in locally and seasonally variable small amounts as aerosols in an unfiltered air sample, including dust of mineral and organic composition, pollen and spores, sea spray, and volcanic ash. Various industrial pollutants also may be present as gases or aerosols, such as chlorine (elemental or in compounds), fluorine compounds and elemental mercury vapor. Sulfur compounds such as hydrogen sulfide and sulfur dioxide (SO 2) may be derived from natural sources or from industrial air pollution.The planetary boundary layer is the part of the troposphere that is closest to Earth's surface and is directly affected by it, mainly through turbulent diffusion. During the day the planetary boundary layer usually is well-mixed, whereas at night it becomes stably stratified with weak or intermittent mixing. The depth of the planetary boundary layer ranges from as little as about 100 metres (330ft) on clear, calm nights to 3,000m (9,800ft) or more during the afternoon in dry regions.
