There is growing evidence that man-made activities are making temperature higher. What might be the man-made causes of temperature rising?

Global warming is the biggest threat to the continuity of mankind. There are several factors contributing to raising the global

temperature

, but there have been agreements in the research field to point out that man-made activities are the main root cause.

This

essay aims to discuss the negative impact of coal and aeroplane on the Earth’s

heat

. They are notorious for the origins of global warming.

Firstly

, producing coal for energy has escalated the world’s climate for years.

For example

, multiple studies conducted by groups of universities show that the waste which gets released to

air

after manufacturing coal causes the

heat

to be trapped in the ozone level. These heats cannot escape

this

planet, which increases global warmth.

Therefore

, coal should be stopped to slow down the rise of

temperature

globally.

Secondly

, the aeroplane is the major contributor to global warming. During COVID 19 lockdowns, there was a plunge in the number of

air

traffic. A research carried out by environmental activists suggests that the

heat

of the world dropped by one Celsius degree.

Although

the decrease in

temperature

is small, it cannot be denied that aviation has a strong, closed relationship with humanity’s biggest threat, the global heating. Because of

this

tie, travelling by

air

is no doubt a primary cause of the escalation in the world’

heat

. To conclude, human-made causes of the annual soar of global

temperature

are the production of coal and

air

travel. These assumptions are backed up by numerous studies which have been conducted by scientists and researchers. In the future, there will be multiple policies aiming to contain these causes.

Otherwise

, human civilization will cease to exist because of global warming
