Climate change is real.
Greetings and welcome to the debate. In this round, I will present my key reasons for believing that climate change is indeed real, And not a hoax, As certain political leaders have said. But first, We must define climate change. The official definition of climate change is: a change in global or regional climate patterns, In particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. My first reason is that we have seen a huge increase in COS22; levels in the atmosphere, And this can be correlated with human industrial activity. In fact, Atmospheric COS22; levels are directly proportionate to human industrial activity. And, Increasing COS22; levels lead to a predictable rise in temperature. You may say that climates change anyway, And COS22; levels will fluctuate naturally, But it is no coincidence that it starts changing rapidly the moment humans figure out how to mine coal and burn fossil fuels. My second reason is that the Earth's temperature has risen by approximately 1"C since 1969. This might not seem like much, But in comparison to previous climate changes, It is vastly significant. Ocean temperatures have also risen by 0. 7"F, Killing a statistically significant proportion of the Great Barrier Reef. My final reason is that Arctic sea ice is shrinking, And polar bears may see the first iceless summer by 2050. So, We can conclude that climate change is indeed real, And not a hoax. I await my opponent's argument!
