What reasons do deniers of global warming give to support their position? Essay sample



Despite the solid evidence that the average temperature on Earth has risen over the past century, climate change still remains a debate. Some radical scientific minds deny the fact that Earth is warming faster than ever, however, their point makes little sense. Proponents of climate change also argue that greenhouse gases caused by human activities are direct contributors to climate change. This is where the actual argument begins. Opponents of the debate claim that human-produced CO2 is insufficient and cannot potentially cause global warming.


As for 2010, 1,000 scientists disagreed that humans were primarily responsible for climate change. Though the planet has warmed 1.4 degrees Fahrenheit over the last century, it is considered a variant of the norm. Earth’s average temperatures fluctuated around +/- 5 degrees Fahrenheit over the past 3,000 years, and an increase in a degree is not considered critical. Moreover, opponents of the human-caused global warming deny a direct causal relationship between CO2 and the temperature rise. They also claim that 50% of the human produced CO2 has been successfully absorbed by oceans and forests. For the rest, they expect global warming to be caused by fluctuations of the solar power.


The scientific argument is always useful as only through questioning we can find the truth. Nevertheless, an overwhelming body of scientific research says that global warming happens and human activity is responsible for it. Over the 20th century, the rise in atmospheric CO2 occurred at a much faster rate than ever before, which proves it was caused by humans. Its isotopic ratio is clearly different from that of a natural CO2, which allows tracing human-produced carbon-dioxide. The rampant melting of the Arctic ice cap is also undeniable.
