2. Polar ice cap - Wikipedia

   en.wikipedia.org/wiki/Polar_ice_cap

   A polar ice cap or polar cap is a high- latitude region of a planet, dwarf planet, or natural satellite that is covered in ice. [1] There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase ...

3. Ice–albedo feedback - Wikipedia

   en.wikipedia.org/wiki/Ice–albedo_feedback

   Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy back to space than open water or any other land cover. [ 1 ] It occurs on Earth, and can also occur on exoplanets.

4. Concentrated solar power - Wikipedia

   en.wikipedia.org/wiki/Concentrated_solar_power

   A solar power tower consists of an array of dual-axis tracking reflectors (heliostats) that concentrate sunlight on a central receiver atop a tower; the receiver contains a heat-transfer fluid, which can consist of water-steam or molten salt. Optically a solar power tower is the same as a circular Fresnel reflector.

5. Polar regions of Earth - Wikipedia

   en.wikipedia.org/wiki/Polar_regions_of_Earth

   Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.

6. Solar radiation modification - Wikipedia

   en.wikipedia.org/wiki/Solar_radiation_modification

   Managing solar radiation using aerosols or cloud cover would involve changing the ratio between direct and indirect solar radiation. This would affect plant life [ 69 ] and solar energy . [ 70 ] Visible light, useful for photosynthesis, is reduced proportionally more than is the infrared portion of the solar spectrum due to the mechanism of Mie ...

7. Ford Expedition - Wikipedia

   en.wikipedia.org/wiki/Ford_Expedition

   The Ford Expedition is a full-size three-row SUV, manufactured and marketed by Ford over four generations since model year 1997, deriving directly from Ford's concurrent generations of its F-150 pickup truck—and marketed since 2007 in regular and extended lengths (the Expedition EL/Max), the latter replacing the Ford Excursion.
