Morphology

thermal + pollution

The meaning is directly derivable: 'thermal' (related to heat) modifies 'pollution' (harmful contamination), so the phrase straightforwardly denotes pollution caused by heat or temperature increase. This adjective+noun composition is common and mirrored in many languages (e.g., contaminación térmica / pollution thermique), so a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

Thermal pollution literally names pollution by heat: thermal means heat and pollution means something harmful put into nature. Picture a factory pipe pouring very hot water into a cold river and making fish sick. So, thermal pollution means a 'harmful increase in water temperature' caused by people.
