Changing energy from the sun has affected the temperature of Earth in the past. However, we have not seen anything strong enough to change our climate.
Any increase in solar energy would make the entire atmosphere of Earth warm, but we can only see warming in the bottom layer.
El Niño Southern Oscillation (ENSO)
ENSO is a pattern of changing water temperatures in the Pacific Ocean. In an 'El Niño' year, the global temperature warms up, and in a 'La Niña' year, it cools down.
These patterns can affect the global temperature for a short amount of time (months or years) but cannot explain the persistent warming that we see today.
This can cause the temperature of Earth to change. However, these cycles take place over tens or hundreds of thousands of years and are unlikely to be causing the changes to the climate that we are seeing today.

The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Forests remove and store carbon dioxide from the atmosphere. Cutting them down means that carbon dioxide builds up quicker since there are no trees to absorb it. Not only that, trees release the carbon they stored when we burn them.
