  2. Climate change - Wikipedia

    en.wikipedia.org/wiki/Climate_change

    Many climate change impacts have been observed in the first decades of the 21st century, with 2023 the warmest on record at +1.48 °C (2.66 °F) since regular tracking began in 1850.

  3. Suess effect - Wikipedia

    en.wikipedia.org/wiki/Suess_effect

    The Suess effect is a change in the ratio of the atmospheric concentrations of heavy isotopes of carbon (13 C and 14 C) by the admixture of large amounts of fossil-fuel derived CO 2, which contains no 14 CO 2 and is depleted in 13 CO 2 relative to CO 2 in the atmosphere and carbon in the upper ocean and the terrestrial biosphere .

  4. Geothermal energy - Wikipedia

    en.wikipedia.org/wiki/Geothermal_energy

    Geothermal energy is thermal energy extracted from the Earth's crust.It combines energy from the formation of the planet and from radioactive decay.Geothermal energy has been exploited as a source of heat and/or electric power for millennia.

  5. Geothermal heating - Wikipedia

    en.wikipedia.org/wiki/Geothermal_heating

    Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 20

  6. Avoiding Dangerous Climate Change (2005 conference)

    en.wikipedia.org/wiki/Avoiding_Dangerous_Climate...

    In 2005, an international conference titled Avoiding Dangerous Climate Change: A Scientific Symposium on Stabilisation of Greenhouse Gases examined the link between atmospheric greenhouse gas concentration and global warming and its effects.

  7. Global dimming - Wikipedia

    en.wikipedia.org/wiki/Global_dimming

    Global dimming is a decline in the amount of sunlight reaching the Earth's surface. [2] [3] It is caused by atmospheric particulate matter, predominantly sulfate aerosols, which are components of air pollution. [4]

  8. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    At the atomic scale, a temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side. This is due to charge carrier particles having higher mean velocities (and thus kinetic energy) at higher temperatures, leading them to migrate on average towards the colder side, in the process carrying heat across the material.

  9. Gaia hypothesis - Wikipedia

    en.wikipedia.org/wiki/Gaia_hypothesis

    The Gaia hypothesis (/ ˈ ɡ aɪ. ə /), also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating complex system that helps to maintain and perpetuate the conditions for life on the planet.
