It's a fact that the average temperatures have been rising in the last years, but our planet's temperatures have always been dynamic, so it's difficult to say.

Yes, and I think it's completely natural. Are humans causing it? I don't know. The average temperature has gone up and down quite a lot over the ages. I think it's to be expected.
