The average American gives off 17 Tons of Co2 a year just by breathing. While global climate change has been a natural progression, humans need to reduce the amount of emissions released into the atmosphere. Global temperatures have risen 1.4 degrees Fahrenheit since the early 20th century, the ice caps have been melting at an accelerated rate, and sea levels are rising due to this accelerated melting.
Deforestation has reduced the amount of oxygen released into the atmosphere while at the same time increasing the amount of CO2 in the atmosphere. This leaves us with less clean, breathable air. Cars and other heavy machinery also contribute to emissions, which pollute our atmosphere. The rise in atmospheric CO2 has clearly been caused by …show more content…
They claim that although temperatures have risen 1-1.5 degrees over the past 20th century, this is still within the bounds of normal temperature fluctuations over the past 3000 years (Mann, Proxy based). Throughout Earth’s history temperatures have constantly changed, so this sudden increase in temperature should be nothing to worry about. Another argument against global warming is the claim that rising levels of CO2 don’t necessarily cause global warming. According to a 2003 study published in Science, measurements of ice core samples show that over the last 240,000 years, periods of natural global warming preceded global increases in CO2. This means that global warming was occurring before any recorded increases in CO2. This argument falls short, however, because there is no accurate way to measure levels of CO2 in the atmosphere from that long ago. Although 1-1.5 degrees may be within the bounds of normal temperature fluctuations over the past 3000 years, it doesn’t explain why temperatures have risen so much in such a short amount of time. It simply states that “the Earth’s temperatures have changed before”, it doesn’t show how temperatures could have risen so much in so little time. It is obvious to see that there is something missing that the opposition doesn’t want to point out, and that is human
