Researchers say that the warm temperature zone is expanding further.
Is the tropical zone of Earth expanding?
The planet Earth is divided into three climate zones: Tropical, temperate and frigid.
The tropical zone extends around the equator from 23.5 degrees north to 23.5 degrees south.
Now researchers say that this warm temperature zone is expanding further.
What are the consequences?
This may be the reason behind severe droughts and bushfires in Australia and parts of the U.S.
What is causing this expansion?
increasing greenhouse gases
aerosols
decreasing ozone may be the factors behind this expansion.
warming oceans are the main reason.
water currents
How the water currents are causing the shift?
Large-scale ocean currents in both the northern and southern hemispheres are the key drivers.
The currents in this region bring the water masses together particularly strongly, the subtropical ocean surface accumulates heat more easily here than in other marine regions.
