Climate change worsens ground-level ozone pollution by raising air temperatures.

Is it true that climate change worsens ground-level ozone pollution by raising air temperatures?

Unclear. Several peer-reviewed sources partially support the claim: a Bavaria projection links projected temperature rises to higher ozone maxima, a Santiago study says rising temperatures worsen ground-level ozone, and reviews note that higher temperatures increase ozone-precursor emissions and that climate change alters ozone formation rates. None of the placed items establishes the general causal claim across regions and conditions.
