What Is the Sun''s Role in Climate Change?

The amount of solar energy that Earth receives has followed the Sun''s natural 11-year cycle of small ups and downs with no net increase since the 1950s. this would, at best, slow down (but not reverse) human-caused global warming. There would be a small decline of energy reaching Earth, and just three years of current carbon dioxide

Climate and Earth''s Energy Budget

At Earth''s average distance from the Sun (about 150 million kilometers), the average intensity of solar energy reaching the top of the atmosphere directly facing the Sun is about 1,360 watts per square meter, according to measurements made by the most recent NASA satellite missions. This amount of power is known as the total solar irradiance.

The Sun is generally considered to produce a constant amount of power (although there are small variances in the output energy depending on sunspot cycles) with a surface intensity of 6.33×107Wm2.

Not all of the solar energy that reaches the Earth's atmosphere is absorbed by the Earth. This is due to something known as.

Energy that is absorbed by the Earth is not the same as the energy incident on the Earth's surface. On a perfectly clear or cloudless day, when the Sun is directly overhead (or at the "zenith"), solar irradiation i.The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere1. It takes solar energy an average of 8 ⅓ minutes to reach Earth from the Sun, traveling about 149 million km (93 million miles) through space to reach the top of Earth’s atmosphere2. Just over half of this incoming solar energy ultimately reaches the ground3. The rest is reflected away by low-level, thick, white clouds or ice or gets absorbed by the atmosphere3. At most about 75% of the solar energy actually reaches the earth's surface, as even with a cloudless sky it is partially reflected and absorbed by the atmosphere4.
