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).
When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4. [14] The average albedo of Earth is about 0.3. [15] This is far higher than for the ocean primarily because of the contribution of clouds.
Solar radiation modification (SRM) (or solar radiation management or sunlight reflection methods [1] or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.
The exhaust from ships already causes more and brighter clouds above the oceans. Marine cloud brightening also known as marine cloud seeding and marine cloud engineering is a proposed solar radiation management technique that would make clouds brighter, reflecting a small fraction of incoming sunlight back into space in order to offset global warming.
Cloud albedo strongly influences the Earth's energy budget, accounting for approximately half of Earth's albedo. [1] [2] Cloud albedo is influenced by the conditions of cloud formation and variations in cloud albedo depend on the total mass of water, the size and shape of the droplets or particles and their distribution in space.

On regular hot summer days, the average air temperature dropped by 0.2 °C to 1.2 °C, while surface temperatures were lower by 2.6 °C to 4.9 °C. [21] Results suggest that cool pavements can enhance comfort for pedestrians, with mean radiant temperature reductions between 0.9 °C and 1.3 °C, and physiologically equivalent temperature ...

This happened because of major improvements in the understanding of cloud behaviour over the subtropical oceans. As the result, there was high confidence that the overall cloud feedback is positive (contributes to warming). [7]: 95 The AR6 value for cloud feedback is +0.42 [–0.10 to 0.94] W m–2 per every 1 °C (1.8 °F) in warming. This ...
