The climograph below shows average monthly temperatures and rainfall in the city of Kolkata. 

The chart compares average figures for temperature and precipitation over the course of a calendar year in Kolkata.

It is noticeable that monthly figures for precipitation in Kolkata vary considerably, whereas monthly temperatures remain relatively stable.

Rainfall is highest from July to August, while temperatures are highest in April and May.

Between the months of January and May, average temperatures in Kolkata rise from their lowest point at around 20°C to a peak of just over 30°C.

Average rainfall in the city also rises over the same period, from approximately 20mm of rain in January to 100mm in May.

While temperatures stay roughly the same for the next four months, the amount of rainfall more than doubles between May and June.

Figures for precipitation remain above 250mm from June to September, peaking at around 330mm in July.

The final three months of the year see a dramatic fall in precipitation, to a low of about 10mm in December, and a steady drop in temperatures back to the January average.

The graph and table below give information about water use worldwide and water consumption in two different countries.

 

The charts compare the amount of water used for agriculture, industry and homes around the world, and water use in Brazil and the Democratic Republic of Congo.

It is clear that global water needs rose significantly between 1900 and 2000, and that agriculture accounted for the largest proportion of water used.

We can also see that water consumption was considerably higher in Brazil than in the Congo.

In 1900, around 500km³ of water was used by the agriculture sector worldwide. The figures for industrial and domestic water consumption stood at around one fifth of that amount.

By 2000, global water use for agriculture had increased to around 3000km³, industrial water use had risen to just under half that amount, and domestic consumption had reached approximately 500km³.

In the year 2000, the populations of Brazil and the Congo were 176 million and 5.2 million respectively.

Water consumption per person in Brazil, at 359m³, was much higher than that in the Congo, at only 8m³, and this could be explained by the fact that Brazil had 265 times more irrigated land.

First, advances in media, such as the Internet and TV, have meant that children spend a large portion of their leisure time in front of a screen.
