The world’s tropical zone is expanding, and Australia should be worried

The Tropics are defined as the area of Earth where the Sun is directly overhead at least once a year — the zone between the Tropics of Cancer and Capricorn.

‘Tropics’ may conjure images of sun-kissed islands,
but the expanding tropical zone could bring
drought and cyclones further south.
However, tropical climates occur within a larger area about 30 degrees either side of the Equator. Earth’s dry subtropical zones lie adjacent to this broad region. It is here that we find the great warm deserts of the world.

Earth’s tropical atmosphere is growing in all directions, leading one commentator to cleverly call this Earth’s “bulging waistline”.


Read the thoughts of the Adjunct Professor of Environmental Geography from, CQUniversity Australia,  Steve Turton, on The Conversation - “The world’s tropical zone is expanding, and Australia should be worried."
