Question

give reason man is partly responsible for global warming

Answer 1

The consensus opinion of climate scientists is that humans are "substantially" responsible for global warming. This is a cautious and responsible view that does allow the possibility, not yet demonstrated, that natural forces play a significant role in current warming. Certainly the last ten years have been the warmest globally since instrumental temperatures began in 1850, and the temperature trend is rising faster than in any previous natural period of temperature change.

Answer 2

1 industries which cause global warming are also set up by humans
2 automobiles causes global warming
3 CFCs also cause global warming
