Stuart is studying weather data for his region. the data was gathered from 1950 to 2016. which observation would provide the strongest evidence that the climate of his region has changed during this time?
a. average annual rainfall for 1985-2016 increased by 20 percent compared to the previous 30 years.
b. total rainfall in 2014 was 30 percent greater compared to 1950.
c. the lowest recorded temperature occurred in 1954.
d. the highest recorded temperature occurred in 2016.

A

Explanation:

The climate of a region is determined through the observation of weather patterns over a long time- usually at least 15 years-  in a region. Studying climate change would therefore also take very long time as meteorologists attempt to perceive changes in these weather patterns. In this case 30 years can be enough to notice a significant increase in rainfall patterns which can be classified as climate change.

a physical change is being made.
