  2. Tipping points in the climate system - Wikipedia

    en.wikipedia.org/wiki/Tipping_points_in_the...

    In climate science, a tipping point is a critical threshold that, when crossed, leads to large, accelerating and often irreversible changes in the climate system. [3] If tipping points are crossed, they are likely to have severe impacts on human society and may accelerate global warming.

  3. Environmental gradient - Wikipedia

    en.wikipedia.org/wiki/Environmental_gradient

    For example, aspects of the landscape such as soil composition, temperature, and precipitation all factor in to an accurate idea of habitable territory a plant species might occupy; information on one of those factors can help form an environmental gradient by which a proximate species distribution may be generated.

  4. Climate risk - Wikipedia

    en.wikipedia.org/wiki/Climate_risk

    Climate risk is the potential for problems for societies or ecosystems from the impacts of climate change. [2] The assessment of climate risk is based on formal analysis of the consequences, likelihoods and responses to these impacts. Societal constraints can also shape adaptation options.

  5. Environmental impact statement - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_statement

    Finding of No Significant Impact (FONSI): Occurs when no significant impacts are identified in an EA. A FONSI typically allows the lead agency to proceed without having to complete an EIS. Environmental Impact Statement. Scoping: The first meetings are held to discuss existing laws, the available information, and the research needed. The tasks ...

  6. Sea level rise - Wikipedia

    A large difference between the two was the addition of SSP1-1.9 to AR6, which represents meeting the best Paris climate agreement goal of 1.5 °C (2.7 °F). In that case, the likely range of sea level rise by 2100 is 28–55 cm (11– 21 + 1 ⁄ 2 in).

  7. Altitudinal zonation - Wikipedia

    en.wikipedia.org/wiki/Altitudinal_zonation

    Montane level: [7] [22] Extends from the mid-elevation forests to the tree line. The exact level of the tree line varies with local climate, but typically the tree line is found where mean monthly soil temperatures never exceed 10.0 degrees C and the mean annual soil temperatures are around 6.7 degrees C.

  8. Effects of high altitude on humans - Wikipedia

    en.wikipedia.org/wiki/Effects_of_high_altitude...

    Sports organizations acknowledge the effects of altitude on performance: for example, the governing body for the sport of athletics, World Athletics, has ruled that performances achieved at an altitude greater than 1,000 metres will be approved for world record purposes, but carry the notation of "A" to denote they were set at altitude.

  9. Height above mean sea level - Wikipedia

    A geoid is needed to convert the 3D position to sea-level elevation. Pressure altimeter measuring atmospheric pressure, which decreases as altitude increases. Since atmospheric pressure varies with the weather, too, a recent local measure of the pressure at a known altitude is needed to calibrate the altimeter. Stereoscopy in aerial photography.
