Exploring the Challenges posed by Expanding Torrid Zone

Imaginary lines dividing the earth into torrid, temperate and frigid zones, is no new concept and have been an integral part of our academic curriculum. In this article we pin our focus on the atmospheric change being reflected by the Torrid stretch as a result of global warming.

The torrid zone defines the geographic and atmospheric distribution between the tropic of Cancer and Capricorn- 30 degree north to 30 degree south of equator. Also known as the tropics, they are invariably exposed to direct sunlight at some point of time in the year, consequently becoming the hottest zone on earth. Today, human beings are faced with the grievous challenge to address the concern of expanding tropics due to the causes and effect of global warming or as scientists term it- sorting the issue of earth’s bulging waistline!

Notable environmentalists claim, it is since early 1980s that the tropics have experienced such swell by 56 to 111 km in both hemispheres and is likely to face the same in near future. Erratic human activities, high green house gas and carbon emissions tend to provoke temperatures to rise, warming up the lower atmospheric layers as well as oceans.

Surprisingly if the zonal shift continues, the subtropical region will encompass Australian cities of Sydney to Perth. This will entail devastating droughts, diverting rainfall from warm temperate zones.

Causes and effect of global warming is compelling cyclones to migrate towards the poles owing to the expansion of tropics, thus, taking along with it the heavy downpours that temperate croplands deserve.

The saddest part happens to be the fact that biodiversity hotspots face the brunt, like in the south west of Australia, where species do not have the option to migrate to an extended cool habitable land, except taking a plunge into the ocean and be rendered extinct!

More than half of Australia lying beyond the southern tropical extreme, makes it a high risk zone, that is susceptible to succumb to the drying impacts of the zonal shifts. Drastic rise in the ocean and air temperatures, unusual rise in sea levels, marked by declining rainfall and unexpected cyclone in pockets is likely to change the biodiversity distribution in the continent.

The current focus should be on adapting to the changing environment besides mulling over sustainable alternative that will serve Australia in the long run. The present reflections point at gearing up for a change in the agricultural output and mining activity. A relatable change could be experienced in the tourism sector.

Rather than anticipating the consequences, one should start building awareness on the need to strengthen the foundation of community development.

The growing challenge of residing in an unsuitable weather condition poses a threat to survival of living creatures at large, some of which are already at the brink of extinction due to shocking impact of global warming since the past few decades. If we, human beings do not mend our ways and do away with our irresponsible conduct, saving the ecosystem will be next to impossible.
