In my opinion, this is a question of the time scale considered: the variations from year to year are obviously dominated by weather, and also decadal variations — such as the warming (probably the increase of the flow) from 1990 to the middle of the 2000s and the subsequent cooling (slowdown of the flow)-- are likely to be mainly natural variations.

We can easily perceive a change in the weather, and if we have some reason to pay attention we can perceive the variation from year to year, but we can not perceive a one - way, decades - long shift in the range of yearly variation that is climate.

Put simply, a «climate variation» is a change in the average weather for a particular time of year; for example, winters becoming warmer.
