   Sep 6, 2019 · The amount of solar energy that Earth receives has followed the Sun’s natural 11-year cycle of small ups and downs with no net increase since the 1950s. Over the same period, global temperature has risen markedly. It is therefore extremely unlikely that the Sun has caused the observed global temperature warming trend over the past half-century.

   Remote sensing by the Pioneer Venus, Venera-15, and Venus Express spacecraft revealed significant latitudinal variations in the mesospheric temperature and cloud structure (Grassi et al. 2010, Lellouch et al. 1997, Taylor et al. 1980, Tellmann et al. 2009, Zasova et al. 2007). In particular, both the cloud top altitude and aerosol scale height at t...

   Radiation carries not only energy but also entropy. Its flux is proportional to that of the radiative flux divided by the temperature at which energy is deposited or emitted. Since heating by solar radiation and cooling by thermal emission occur at different altitudes and temperatures, planets have non-zero (usually negative) balance of radiative e...

   The planets receive solar energy in the ultraviolet, visible, and near-infrared spectral ranges, in which their atmospheres are relatively transparent. The surface and the lower atmosphere eliminate the absorbed energy by emitting radiation at infrared wavelengths. Strong absorption bands of gases and aerosols trap the heat in the lower atmosphere ...

   Could solar energy be collected from Venus?

   • Venus would also need to be cooled down from the scorching sun using some kind of  sun shade, which has the side effect of collecting solar energy for potential human or robotic use. The sun-observing Solar Orbiter spacecraft makes regular flybys at Venus, taking measurements of the planet's magnetic field as a side project. (Image credit: ESA)

   Why does Venus absorb less solar energy than Earth?

   • The strongly scattering clouds reflect more than 75 % of incoming solar flux back to space, so that Venus absorbs less solar energy than the Earth does, even though it is 30 % closer to the Sun.

   How much solar energy does Venus absorb?

   • Due to its high albedo the planet absorbs only 157 ± 6 W/m 2 on average, less than that deposited on Earth ( ≈ 240 W/m 2), despite the fact that Venus is 30 % closer to the Sun. Both models and observations show that less than 10 % of the total solar energy incident on Venus reaches the surface, and only 2.5 % is absorbed there.

   Why is Venus a special case among terrestrial planets?

   • As noted above, on Venus, most of the solar energy is deposited in the upper cloud ( > 57 km) rather than at the surface. This makes Venus a special case among terrestrial planets because its atmosphere is heated from the top while the atmospheres of Mars and Earth receive most of their solar energy at the surface.

   How does solar radiation affect the climate of Venus?

   • Absorbed solar and thermal radiation internal to the atmosphere play a dominant role in many chemical and dynamical processes that define the climate of Venus. In some cases the radiative effects are pushed to their extremes in ways that make Venus unique among the terrestrial planets in the Solar System.

   What is the reflected solar spectrum of Venus?

   • (From Titov et al. 2007) Observations of the reflected solar spectrum of Venus are summarized in Crisp and Titov (1997), Moroz et al. (1985, 1983). A major fraction of the incoming solar flux is scattered back to space by thick clouds that are mainly composed of sulfuric acid and completely cover the planet.

   When it starts to die, the Sun will expand into a red giant star, becoming so large that it will engulf Mercury and Venus, and possibly Earth as well. Scientists predict the Sun is a little less than halfway through its lifetime and will last another 5 billion years or so before it becomes a white dwarf.
