things to say instead of "climate change"

Instead of the bland, Frank Luntz-ian term "Climate change," try:

Climate disruption
Oil company-caused climate disruption [source]

Instead of "Climate change denier," try:

Atmospheric carbon pusher
Air poisoner
Corporate air poisoner
Icecap melter
Institutional icecap-melter
Venusians (after our planetary neighbor baked to cinders by greenhouse gases)
Vulcans (death cult worshipping volcano-like impacts on the air)

On the topic of counter-propaganda responding to the carbon pushers, see also:

Duly noted: the futility of using fossil-derived power to link to an anti-hydrocarbon video, causing more fuel-burning.
