You are right, the changes are small and usually hard to see directly.

But we also have to remember that warming is not uniform across the planet, where I live the Berkeley Earth site [1] shows an average 2.5 C warming since the 1850s.

It is especially visible if your regular winter temperatures go below 0 C, but not much. Even 1-2 C warming may be seen as a much smaller snow coverage than before.
