Clouds are important in that they can form precipitation and bring rain to crops and plants. They also shade the earth, affecting the temperature and keeping sunlight from directly hitting plants.
Actually, the clouds don't make it warmer outside; clouds keep it warmer outside.

Sunlight is the source of energy for the earth, and some of that energy is in the form of heat.
