The humans to have become a big factor in the past few hundred years. The reason for that is that the humans with their activity started to release lot of greenhouse gases into the atmosphere, especially CO2 and methane. That has been changing the composition of the atmosphere, and the temperatures have been rising. The higher the temperatures, the more ice is melting around the poles and on the high mountains, resulting in an increase in the sea levels.
