1) how have human factors contributed to climate change, and what evidence supports these factors?

2) how have nonhuman factors contributed to climate change, and what evidence supports these factors?

3) what can we do to reduce the human impact on climate change? develop at least three practical strategies.

Human factors contributed to climate change through the usage of CFC's common in sprays, aerosols, refrigerant in air conditioners and other manufacturing industries that thins out the ozone layer thereby lessenign the protection from the sun rays. CO2 charged form The non-human factors are volcanic eruptions, solar output and heat generating natural processes. ways to reduce human impact are (1) reduce the use of sprays, aerosols esp. with CFCs; (2) become energy efficient and (3) reducing your wastes.
