Lynch naturally didn't believe in the Druids' explanations. In fact, anyone with faith can interpret this sweltering heat in a way that aligns with their beliefs, and they can all find a narrative that best serves their faith. Other "heresies" could be responsible for this unpleasant matter, while they themselves are the only solution to the predicament.
As a Mage, Lynch only believed in himself and what he could achieve. He used only his own eyes and brain to think, never allowing others to dictate his actions. Mages neither placed their hopes in deities nor believed that the power of faith could save everything. They simply believed that hints of what was to come could be found in past events.
"Druids, weren't you all inquiring about the giant dragon?" Lynch was unwilling to discuss the topic of natural faith with these Druids, so he said, "Now is a good time."
