The effect of clouds on Earth's temperature depends on their altitude and type. High, thin clouds like cirrus and cirrostratus primarily transmit incoming solar radiation, allowing most of it to reach Earth's surface. However, these clouds also trap some of the infrared radiation emitted by Earth, re-emitting it back towards the surface, which has a warming effect.
On the other hand, low, thick clouds like stratocumulus and stratus primarily reflect solar radiation back into space, preventing it from reaching Earth's surface. This reflective property, known as cloud albedo, has a cooling effect on the planet.
Therefore, the statement that high clouds primarily reflect solar radiation and cool the surface of the Earth is not entirely accurate. While they do reflect some solar radiation, their overall effect on Earth's temperature is more complex due to their ability to trap infrared radiation.
Low, thick clouds, on the other hand, are the most effective at cooling Earth's surface due to their high albedo. They reflect a significant portion of incoming solar radiation, reducing the amount of energy absorbed by the planet.
In summary, high clouds have a more nuanced effect on Earth's temperature, while low, thick clouds are the most effective at cooling the planet through reflection.
Low, thick clouds primarily reflect solar radiation and cool the surface of the Earth. High, thin clouds primarily transmit incoming solar radiation; at the same time, they trap some of the outgoing infrared radiation emitted by the Earth and radiate it back downward, thereby warming the surface of the Earth. Marine stratus and stratocumulus clouds predominantly cool the Earth. They shade roughly a fifth of the oceans, reflecting 30 to 60 percent of the solar radiation that hits them back into space. In this way, they are reckoned to cut the amount of energy reaching the Earth's surface by between 4 and 7 percent.Clouds are between the Earth's surface and the Sun, and liquid water-droplet clouds are quite reflective of the Sun's short wavelength radiation. High clouds make the world a warmer place. If more high clouds were to form, more heat energy radiating from the surface and lower atmosphere toward space would be trapped in the atmosphere, and Earth's average surface temperature would climb.High clouds make the world a warmer place.

While some types of clouds help to warm the Earth, others help to cool it. Stratus clouds: A thick, low grey blanket, stratus clouds block sunlight from reaching the Earth like an umbrella and thus have a net cooling effect. Cloud albedo depends on the total mass of water, the size and shape of the droplets or particles and their distribution in space. Thick clouds reflect a large amount of incoming solar radiation, translating to a high albedo. High clouds primarily reflect solar radiation and cool the surface of the Earth." This statement is not entirely correct because while high clouds do reflect some of the Sun`s radiation back to space, they also trap some of the Earth`s heat, leading to a warming effect, not a cooling effect. On average, clouds reflect 20% of the incoming solar radiation, but the actual amount of individual clouds can vary. For example, thin clouds have an albedo of 30 to 50%, while thick clouds can have an albedo of up to 90%. So, on average, only 70% of the solar radiation reaches the sea surface.
