Do you believe humans are responsible for global warming or do you believe this is part of a natural cycle of Earth, like periodic ice ages?

yes I do Just look at how we treat the planet we live on right now.

Explanation:

If I had to choose I think it would be humans fault.

Explanation:

To think that we are the reason for global warming and everything would make the next person a little insulted but when you think about it a long time ago when there was not many technological advancements there was not complains of global warming or anything until recently. Temperatures are starting to rise and more and more pollution is filling our atmosphere. As it could be true that it might not be entirely our fault as humans I think we took a major part in it.

Hope this helps :)
