The opposing argument is that people are making is as follows: 'climate-alarmists' misuse climate-science as a means of making political change.
It is not a denial of all climate-change science.
I don't care to argue this topic because I'm not expert nor do I care to pretend to be one on the topic of climate change, but this misrepresentation of the opposing views is part of the liberal-bubble so many people live in - all while smugly assuring themselves how much smarter they are than everyone else.
