The first scene – zooming into earth – can tie in with the game and how in the game you hop from one extreme place to the other, the earth tying them all together. And since climate begins on a zoomed out scale, it seemed appropriate.
Second scene – farm scene. Shows a nicer side to climate change. The ‘animals’ seems happy, peacefully sunny, etc etc.
Third scene – in the desert you see cracks emerge in the ground and plants shrivel as the sun grows and travels upwards.
Fourth Scene – Arctic. You see the ice crack, showing water, as penguins ‘waddle’ down the icy slope.
