4 Is there reliable evidence of climate change? If so give an example of a very solid piece of evidence to support that the climate is changing. If not give an example of a very solid piece of evidence to support that the climate is not changing.

5 Is there reliable evidence of anthropogenic global warming? If so give an example of a very solid piece of evidence to support that humans a driving global warming. If not give an example of a very solid piece of evidence to support that the our present warming is a natural variation.
