Is it true that the Earth’s climate systems are driven by the electromagnetic radition from the sun, as well as its reflection, absorption, storage, and redistribution amoung the sphere?

Totally. Earth's climate systems are driven by the electromagnetic radiation that comes from the Sun. The incoming radiation that comes from the Sun is reflected by the clouds, passes through Earth's surface, or is even absorbed by the planet's atmosphere. The atmosphere warms thanks to the chemical reactions of larger aerosol particles in the atmosphere absorbing this radiation.
