Interesting Fact:

The sun is the source of energy for the earth's climate system. Although the sun's energy output appears constant from an everyday point of view, small changes over an extended period of time can lead to climate changes. Some scientists suspect that a portion of the warming in the first half of the 20th century was due to an increase in the output of solar energy.
Image of the increases in atmospheric CO2 and temperature are real.

A century of change
