What does warmist mean? Is it just a typing error for warmest?
Well, no, it isn't. A warmist or global warmist is someone who believes that the human race is primarily responsible for global warming (the increase in surface temperatures over the last several decades). This term combines the ideas of global warming and alarmist to describe a person spreading the alarm about climate change and global warming.
Warmist began as a neutral term. However, it is used as a put-down by coolists or deniers, people on the other side of the climate change debate. In particular, some climate scientists were labelled warmists in 2009 when critics suspected them of suppressing data.
