Droughts in California have become more common over the past few decades

Explanation:

Normally people get confused between three terms: weather, season and climate and use them in a wrong manner.

Weather: It is an environment condition for a short period of time over a small area.

Season: A weather pattern common for one hemisphere of the Earth for a period of 3 months.

Climate: Weather pattern for a very long time (more than decades).

Using this you can easily see that only statement 2 reflects the change in climate. Other statements only shows the temporary weather phenomenon.
