The image, taking up most of the space in the poster, is an hourglass split into two portions, one above the other. The top part shows glaciers melting and the water drips into the bottom part, which contains a city, representing/symbolising the world. As the water drips, the water level in the bottom part of the hourglass gradually increases, until it will the city.
The grey background makes it so that there isn't a sharp contrast between it and the main picture, causing it to be painful to the eyes, but still placing the emphasis on the main picture.
There are two sentences; 'We are running out of time' and 'Act now before it's too late'. The first sentence is placed in the top part of the hourglass and the second sentence, the bottom part. This is to control the reading flow of the audience as they will most likely read left to right and top to bottom.
The image takes up the most space, while the text is small and contained in the hourglass, bringing focus to the hourglass.
The two sentences; 'We are running out of time' and 'Act now before it's too late', further intensifies the meaning of the image. The text refers to the rising water levels flooding the cities, encouraging citizens to do their part to stop global warming before the above-mentioned happens.
