But it’s more than just temperature. Add salinity to the equation. I can’t tell you how salinity of any particular place changes with a temperature change, but it does. Add current, add all the other chemicals that are dropped into the ocean….
How does every coral on the the Great Barrier Reef know to spawn one time a year? How does a turtle find its way back to the place they were born to lay eggs? There are nuances well beyond our understanding and will outlive us. Coral will come back, but perhaps not in its current form, and probably not in our lifetimes.
I use mine all the time. I have about a 1/4 mile walk to get to my car, I like to start it in winter to heat up, or summer to cool down before I get to it.
It’s a luxury, but one I enjoy.
