  2. Climate engineering - Wikipedia

    en.wikipedia.org/wiki/Climate_engineering

    [4]: 168 [5] Carbon dioxide removal techniques remove carbon dioxide from the atmosphere, and are part of climate change mitigation. Solar radiation modification is the reflection of some sunlight (solar radiation) back to space to cool the earth. [6] Some publications include passive radiative cooling as a climate engineering technology.

  3. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    An alternative to the earth-to-air heat exchanger is the "water" to earth heat exchanger. This is typically similar to a geothermal heat pump tubing embedded horizontally in the soil (or could be a vertical sonde) to a similar depth of the earth-air heat exchanger. It uses approximately double the length of pipe of 35 mm diameter, e.g., around ...

  4. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    Reducing the extremes of temperature change will reduce the incidence of damage to membrane systems. Covering membranes with materials that reflect ultraviolet and infrared radiation will reduce damage caused by UV and heat degradation. White surfaces reflect more than half of the radiation that reaches them, while black surfaces absorb almost all.

  5. Climate change mitigation - Wikipedia

    The global temperature will rise by 2.7 °C by the end of the century with current policies and by 2.9 °C with nationally adopted policies. The temperature will rise by 2.4 °C if countries only implement the pledges for 2030. The rise would be 2.1 °C with the achievement of the long-term targets too.

  6. Solar radiation modification - Wikipedia

    en.wikipedia.org/wiki/Solar_radiation_modification

    SRM aims to increase Earth's albedo by modifying the atmosphere or surface to reflect more sunlight. A 1% increase in planetary albedo could reduce radiative forcing by 2.35 W/m², offsetting most of the warming from current greenhouse gas concentrations. A 2% increase could counteract the warming effect of a doubling of atmospheric carbon dioxide.

  7. Planetary boundary layer - Wikipedia

    en.wikipedia.org/wiki/Planetary_boundary_layer

    Interactions between the carbon (green), water (blue) and heat (red) cycles in the coupled land–ABL system. As the atmospheric boundary layer decreases in height due to subsidence, it experiences an increase in temperature, a reduction in moisture, and a depletion of CO 2. This implies a reaction of the land surface ecosystem that will ...

  8. CO2 fertilization effect - Wikipedia

    en.wikipedia.org/wiki/CO2_fertilization_effect

    Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]

  9. Stratospheric aerosol injection - Wikipedia

    en.wikipedia.org/wiki/Stratospheric_aerosol...

    The effect of major volcanic eruptions on sulfate aerosol concentrations and chemical reactions in the atmosphere. Major volcanic eruptions have an overwhelming effect on sulfate aerosol concentrations in the years when they occur: eruptions ranking 4 or greater on the Volcanic Explosivity Index inject SO 2 and water vapor directly into the stratosphere, where they react to create sulfate ...
