Prompt: 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. Ċ 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. Ċ 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. Ċ 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.
