  3. Solar activity and climate - Wikipedia

    en.wikipedia.org/wiki/Solar_activity_and_climate

    Since 1978, solar irradiance has been directly measured by satellites with very good accuracy. [11]: 6 These measurements indicate that the Sun's total solar irradiance fluctuates by +-0.1% over the ~11 years of the solar cycle, but that its average value has been stable since the measurements started in 1978.

  4. Solar constant - Wikipedia

    en.wikipedia.org/wiki/Solar_constant

    The actual direct solar irradiance at the top of the atmosphere fluctuates by about 6.9% during a year (from 1.412 kW/m 2 in early January to 1.321 kW/m 2 in early July) due to the Earth's varying distance from the Sun, and typically by much less than 0.1% from day to day.

  5. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 122 PW·year = 3,850,000 exajoules (EJ) per year. [12] In 2002 (2019), this was more energy in one hour (one hour and 25 minutes) than the world used in one year. [13] [14] Photosynthesis captures approximately 3,000 EJ per year in biomass. [15]

    Of the 283 misleading X posts that CCDH analyzed, 209, or 74% of the posts, did not show accurate notes to all X users correcting false and misleading claims about the elections, the report said.

  8. Radiative forcing - Wikipedia

    en.wikipedia.org/wiki/Radiative_forcing

    The intensity of solar irradiance including all wavelengths is the Total Solar Irradiance (TSI) and on average is the solar constant. It is equal to about 1361 W m −2 at the distance of Earth's annual-mean orbital radius of one astronomical unit and as measured at the top of the atmosphere. [42]
