Answer:
Some of the various things that humans do to the environment is pump CO2 into the air with Fossil Fuels and using Power Plants, Cutting down trees make more CO2 which can make the Earth hotter and cause Global Warming. Some natural things that can tend to affect climate can be changes in Volcanic activity, Solar activity with the sun, and Earth's orbit around the sun.
Explanation:
It may seem crazy how Earth's orbit around the sun make climate change, but how else would 4 seasons exist. The orbit tends to be in an oval shape. The top parts of the oval, would represent winter and fall because of the distance between the sun decreases. The closer sides of the oval however, would represent Summer and spring because those are the warmer months and show that Earth is closer to the sun.
