Question

earths average temperature has risen over the past century. most climate scientists attribute the temperature rise to increased concentrations of greenhouse gases released into the atmosphere by humans. this rise in average temperature caused by humans is known as global warming. this graph shows earths average temperature change between 1900 and 2015. the temperature change for each year is the difference between the average temperature in that year and the average temperature in 1900. the data come from averages of measurements taken at weather stations around the world. based on this graph, about how much higher was the average temperature in the year 2015 than in the year 1900? 0.5°f 1°f 1.5°f 2°f

Explanation:

Step1: Analyze the graph

Look at the value on the y - axis (temperature change) corresponding to the year 2015.

Step2: Estimate the value

From the graph, the temperature change in 2015 is approximately \(1.5^{\circ}F\). Since the temperature change is calculated as the difference between the average temperature in a year and that in 1900, this value represents how much higher the average temperature in 2015 was compared to 1900.

Answer:

\(1.5^{\circ}F\)
