"Make no mistake: without concerted action, the very future of our planet is in peril," says Christine Lagarde, head of the International Monetary Fund. Our Planet Earth is facing a huge threat by global warming due to intensified use of fossil fuels and an increase rate of harmful gases such as carbon dioxide and nitrous oxide. Many scientists believe that climate change is occurring and they provide some scientific evidence to prove this, yet some people find it hard to believe that global warming actually exists.
Global warming is defined as a gradual change in the overall temperature of the earth 's atmosphere caused by harmful greenhouse gases. Global warming is caused by carbon dioxide and other air pollution that are collecting in the atmosphere like a thickening blanket, trapping the sun 's heat and causing the planet to warm up. Global warming was first claimed by a Swedish scientist named …show more content…
Nevertheless, some people find it hard to believe this as some other researchers argue that the Mann et al curve has been revealed as a statistical contrivance. There is no credible evidence that former climate was inflexible, nor that 20th century changes in AGT were unfamiliar, nor that dangerous human warming is proceeding.
However, if global warming turns out to be real, the consequences of it can be devastating. Global warming can cause sea level to rise, the average global sea level has increased eight inches since 1880, and this can be very destructive as it increases flooding risks to low-lying populations. Global warming also increases heat waves which creates serious health risks and can lead to heat stroke, heat exhaustion etc. Additionally, global warming generates severe weather, lack of snowmelt, severe crop failure and
