Surface Temperatures of Major Cities in Australia and India


Berkeley Earth is a California based non-profit focused on land temperature data analysis. This organization was founded in 2010 with the goal of addressing major concerns from outside the scientific community regarding global warming.


We try to find out how the land temperatures have changed through time (1750-2012) by analyzing land temperatures of major cities in Australia and India.

The data consists of about 8.5 million rows comprising of land temperature information , city name, country, longitude and latitude. The data can be found here.

How have the average temperatures changed over time?

In the above plots we see that average temperatures in 2012 are the highest. The above results can be attributed to massive vehicular ownership and industrialization, causing the increase of greenhouse gases in the atmosphere.

We plot similar results for Australian Cities

The plots for Australian cities tend to dip in the middle due to the fact that winters occur in the months of June-August in the Southern Hemisphere. We observe a slight increase in temperatures as the years go by.

How have the temperature distributions changed over time?

The red line represents the mean of the average temperature and the blue line represents the median. As the years roll by ,we see that the mean and median increases.

The above results show that global warming is an imminent threat, unless we act accordingly.

Thanks for reading! Stay tuned for more updates!

I would recommend the reader to visit the Berkeley Earth website to understand the work they do.

Have a nice weekend!
