Which of the following best reflects a change in climate: 1. its very windy today and will rain later. 2- droughts in california have become more common over the past few decades. 3- there is a hurricane forming off the coast of florida 4- tropical climates are likely to be wet and warm.

1) is wrong because it is talking about the weather, which is like climate, but much more short term.

2) is correct, because it is talking about California's weather as a whole rather than just a specific occurence of weather changing over time.

3) is wrong because that is just a statement about a result of Florida's climate, not a change of it.

4) is also incorrect because that describes a climate, not a change in the climate.

this is what ive found

Explanation:

Brightness is a description of a stars luminosity as viewed from Earth.

A star can be very hot and large but be so far away that it's brightness is not very bright - dim.

A star can be quite cool but be close to Earth and it's brightness will be greater than one further away.
