The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
Human's greenhouse gas emissions have disrupted the Earth's energy budget. Due to elevated atmospheric greenhouse gas concentrations, the net difference between the amount of sunlight absorbed by the Earth and the amount of energy radiated back to space has risen from 1.7 W/m 2 in 1980, to 3.1 W/m 2 in 2019.

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. The media tends to also use climate engineering for other technologies such as glacier stabilization, ocean liming, and iron fertilization ...
Refrigeration and air conditioning account for about 10% of global CO 2 emissions caused by fossil fuel-based energy production and the use of fluorinated gases. Alternative cooling systems, such as passive cooling building design and passive daytime radiative cooling surfaces, can reduce air conditioning use. Suburbs and cities in hot and arid ...
[9] [failed verification] Deflecting a small amount of the sun's energy from the Earth's atmosphere would reduce the amount of energy entering the ecosystem of the Earth. Some proposals for the development of space mirrors also focus on the ability to change localized lighting conditions on the surface of the Earth by shading certain sections ...

Earth's energy budget (or Earth's energy balance) is the balance between the energy that Earth receives from the Sun and the energy the Earth loses back into outer space. Smaller energy sources, such as Earth's internal heat, are taken into consideration, but make a tiny contribution compared to solar energy.
Air travel is one of the most emission-intensive modes of transportation. [43] The current most effective way to reduce personal emissions from air travel is to fly less. [44] [45] New technologies are being developed to allow for more efficient fuel consumption and planes powered by electricity. [45]
