Photosynthesis
Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar.. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light. However, not all organisms use carbon dioxide as a source of carbon atoms to carry out …
Water and Energy Cycles
Even though the energy cycle on the Earth is an "open system" driven by solar radiation, the amount of water on the Earth does not change on shorter than geological timescales (Oki, 1999; Oki et al., 2004), and the water cycle itself is a "closed system."

Graphic: Temperature vs Solar Activity
The amount of solar energy 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.

Continuous observation of TSI from space started since 1979. The observations reveal that the TSI varies with the 11-year solar cycle. From solar minimum to solar maximum, there is an increase of about 0.1% in the TSI, indicating that solar energy flux is not a true constant, contrary to the use of the term "solar constant".

OverviewObservational historyDefinitionCycle historyPhenomenaPatternsEffectsSolar dynamo
The idea of a cyclical solar cycle was first hypothesized by Christian Horrebow based on his regular observations of sunspots made between 1761 and 1776 from the Rundetaarn observatory in Copenhagen, Denmark. In 1775, Horrebow noted how "it appears that after the course of a certain number of years, the appearance of the Sun repeats itself with respect to the number and size of th…
Climate and Earth''s Energy Budget
On average, 340 watts per square meter of solar energy arrives at the top of the atmosphere. Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). Most solar energy is absorbed at the surface, while most heat is radiated back to space by the atmosphere.
