Question

What kind of data would one need to prove that a particular city has become warmer over last few decades?

• A. Maximum temperature among all the days.
• B. Average temperatures over the decades.
• C. Minimum temperature among all the days.
• D. Temperature on the day of analyzing the climate.

Answer 1

The correct option is B Average temperatures over the decades.

$\bullet$ To say that a particular place has become warmer or cooler, one would need the average temperature of that place over few decades. If the temperatures are found to be increasing every decade, then it can be concluded that the city is getting warmer.
$\bullet$ By analysing such data (using tools like tables, graphs, average, etc), one can prove the change in the climate of a particular place.
