There is no disagreement that the earth’s temperature has always changed over time. There are periods of warming and cooling. It appears we are in a period of warming. The debate between “warmists” and “skeptics” is about whether human Co2 emissions are the cause of warming, whether the relatively small effects of these emissions will compound into larger changes, and, if so, whether, the benefits of remediation outweigh the costs. By “warmists,” I mean Global Warming Alarmists who believe that warming is caused by humans and will have disastrous consequences for humankind if unchecked by remediation, no matter how costly.
