Anything lah, humans will always find something to console themselves.
Please, volcanoes eruptions produce enough sulphur dioxide to induce global warming, animals give out enough carbon dioxide to cause global warming, plants planted on certain type of soils will cause global warming, etc etc.
Whatever it is, humans may or may not be the cause. More of, we played just a small part in causing global warming, our Mother Earth caused this because she has mountains, she has soil, she has volcanoes and what nots.
Enough of this bullsh
it.
