Global mean temperature was changing the most rapidly in 2005. How quickly was the temperature changing in 2005
AysviL [449]

The temperature was changing at a rate of 2.925 degrees Celsius in 2005

<h3>How to determine the rate in 2005</h3>

From the graph (see attachment), we have the following ordered pair

(x,y) = (5,14.625)

The above means that, the temperature in 2005 is 14.625 degrees Celsius

So, the rate in 2005 is:

Rate = \frac{14.625}{5}

Rate = 2.925

Hence, the temperature was changing at a rate of 2.925 degrees Celsius in 2005
