Aerosols influence Earth’s climate both directly, by scattering and absorbing sunlight, and indirectly, by altering the reflectivity of clouds. (...) Albedo effect Albedo is the ability of a surface to reflect sunlight (solar radiation). Snow and ice have high albedo – much of the sunlight hitting surfaces covered with snow and ice bounces back. (...) Therefore, snow and ice which are covered in soot from pollution no longer reflect sunlight, but absorb it and so melting increases.

Too little Sun impacts our mood and well-being and increases the risk of Vitamin D deficiency. Overexposure to sunlight causes harmful effects on the skin, eyes, and immune system. (...) This influence is seen in seasonal variations of psychiatric phenomena related to exposure to longer and shorter sunlight hours, especially mood and anxiety symptoms, as well as suicide.  Sunlight is also necessary for the production of vitamin D, which helps to regulate the amount of calcium and phosphate in the body, both are needed to keep bones and teeth healthy.

Passive solar techniques include orienting a building to the Sun, selecting materials with favourable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. The solar photovoltaic system consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity. Concentrated Solar Power (CSP) systems concentrate direct sunlight to reach high temperatures. This heat can then be used to power a steam turbine which drives a generator. Solar water heating is the conversion of sunlight into heat for water heating using a solar thermal collector.

“We have seen this in the heatwaves in Europe and China this year when stable high atmospheric conditions, sunlight and low wind speeds were conducive to high pollution levels,” said Prof. (...) The combustion of fossil fuels (a major source of carbon dioxide (CO 2 )) also emits nitrogen oxide (NO), which can react with sunlight to lead to the formation of ozone and nitrate aerosols. (...) High aerosol amounts – and thus poor air quality - can cool the atmosphere by reflecting sunlight back to space, or by absorbing sunlight in the atmosphere so that it never reaches the ground.

The Sun and seasons The tilt of Earth’s axis relative to its orbit around the Sun determines the duration of daylight and the amount of sunlight received at any latitude, ranging from polar to equatorial regions. (...) When it is the summer solstice in the Northern Hemisphere, the areas north of the Arctic circle receive sunlight for a full 24 hours, while areas south of the Antarctic circle have a full day of total darkness. (...) During the summer solstice the Northern Hemisphere of Earth is tilted towards the sun resulting in increased sunlight and warmer temperatures, this results in continuous daylight in far northern countries such as Iceland and Norway.

Wasabi plants must be sheltered from direct sunlight from spring to autumn. To do this, East Asian Alder trees native to the area are planted in wasabi fields to create shade. (...) We need to pay careful attention - particularly in the early stage of the plants – that they are not attacked by pests or damaged by heat and strong sunlight. “ Wasabi farmers have a great respect for the entire ecosystem, recognising that each part, from trees to the area’s biodiversity, plays a role in protecting the wasabi plants. (...) Because of this, I am proud of the rich nature in our area, as well as the clean and good quality water.
