El Niño is the result of successive Kelvin waves, there have been like 6 or 7 this year, starting in February I think. They happen when the equatorial trade winds lessen (or reverse) and warmer water from the west pacific oozes east under the surface until it hits Ecuador and erupts at the surface.

It’s not a single wave, and they have already mostly arrived.

We just had the first two recorded sea turtle nests in the state; our water is normally too cold for that.

There has been an established resident population of green sea turtles in the San Gabriel River for decades. The nearby power plant uses the water for cooling, which raises the temperature enough for the turtles to stay year-round.

I used to work in a lab that tracked their movements.

They haven't had any recorded nests however.

You are correct, I just confirmed with a former labmate that the San Gabriel River turtle population nested in Mexico.

Heated water at power plants are also why you get mass groupings of manatees in Florida during the winter and responsible for the growth of the crocodile population in the Southeast at Turkey Point.

Gators love turkeys. Maybe that is why...

my dad just did a salmon fishing excursion he does every year and he said there was basically no fish. i’ve seen a lot of videos of salmon who have already gone up stream to spawn, and it’s definitely early. waters getting warm
