Climate Change help!?

Question

Im doing an assignment on Climate Change and one of the questions is

How have humans contributed towards climate change (i believe they are saying in a good / bad way what did humans do to climate change

Answer 1

The Earth's climate has been changing in natural cycles for billions of years. Volcano eruptions have put more ash into the atmosphere, than all of what man has done. The Earth is currently in an ice age, and coming out of it by warming. When the temperature rises, ice melts. Man has no effect on the Earth's climate

The same climate change is happening on Mars

Answer 2

Humans have contributed by polluting the d**n air.. start from there.

They are also cutting down trees. Which not only has an affect on oxygen and carbon dioxide, but on the ecosystem. This could mean less genetic diversity for some species.. which can have an affect on the climate.

Tons of examples.. but those are two that will get your ideas started.
