A healthy dose of solar radiation
Our sun is 99% of the total mass of the solar system. It’s this solar energy that heats the Earth.
The balance of Earth’s temperature relies on how much energy enters and leaves the planet’s system.
When incoming energy from the sun is absorbed by the Earth system, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming.
When absorbed energy is released back into space, Earth cools. Natural and human causes can influence Earth’s energy balance
