Anyone referring to a scientist with the pejoratives “denier” or “alarmist” is engaging in politics or propaganda. And using the term “climate change” without distinguishing between natural and human causes signals a (perhaps deliberate) sloppiness in thinking. Many an article that purports to be about how humans have broken the climate (or how we must reduce our emissions to “fix” it) is nevertheless filled with examples of climate trends that are not attributable to (or fixable by) humans.
