I think OP meant that if someone claims that climate change would is not an existential threat, they are claimed as deniers. There is one axis for balancing short term vs long term issues, and so called deniers believes that we are on the in the correct point or right of that in that axis. Activist believes we are in the far left end of the axis, that we are risking long term for fixing short term issues.
