How is it Religion to have a theory that you're trying to prove? You seem to lack a basic understanding of the scientific method. Her theory is: "climate change is involved". And she is searching for evidence, that is, she is trying to prove it. She doesn't even claim that climate change is involved, it is clearly marked as her opinion. Just like Einstein had the theory that time had to be relative, and then set out…
She doesn't posit a plausible mechanism for her theory, does she? It's just the fallback position, "it must be climate change", just a small upgrade from "it must be god". Click on that list I linked above (and they stopped adding to that years ago!).
Besides, the sea is getting measurably hotter and more acidic and from the article, which you say you did not read, some of the starfish recovered when put in cooler water:
The virus probably isn’t the whole story, both Lahner and Raimondi say. Lahner took sea stars that were disintegrating at 54 degrees Fahrenheit and cooled their water to 50 degrees. "They all went from falling apart, having their viscera hanging out, to pretty healthy in a day," she says. "I came back, and they were like, ready for the cover of Vogue. They were perfect." So temperature may play a role in the animals’ ability to recover as well.
