oh boy . Yes , you can find arguments against global warming . about 12 % of published scientific research on the matter claims that there is no global warming . This can easily be explained by statistical errors after all , most research only requires a confidence level of 95 % or 97 . 5 %, which means that for every 100 papers published , there should be between 25 that commit a type 1 error incorrect rejection of null hypothesis , assuming climate change is the null hypothesis . 98 % of all published scientific research supports the idea that global warming is actually a real thing , and contributed to largely by human use of fossil fuels and methane emission . The heat trapping properties of carbon dioxide have been demonstrated about 100 years ago . Just like homeopathy , there is no respectable scientific institution or university on the planet whose position is yeah , no one knows for sure . Why is that ? If you want some hard evidence , here is a good start
