This article correctly points out that whenever there is an El Nino current warming the Pacific, the Carbonazis attempt to link it to human activity.
The science says something else.
It is clear from the above thermal image of El Nino that the heat bloom originates from a point source in the western Pacific, then spreads out as it flows east towards the Americas.
Here are some more historic measurements of El Nino.
Human activity is spread across the globe, yet Historically the El Nino heat emerges from a point source!
Now let us look at the above maps aligned with a map of the Pacific Ocean floor!
The heat blooms are originating form the same location in the Pacific.
Let's take a detailed look.
Every one of those conical-shaped projections above the ocean floor is a volcano! The ones that break the surface form islands, such as here in Hawaii. Nobody actually knows how many are active at any given time. Indeed nobody actually knows how many active volcanoes and thermal vents there are on the floor of the world's oceans. Absent a seismic event, or a patch of pumice floating on the ocean above the volcano, there is as yet no means for knowing which and how many of those volcanoes are active.
Clearly, the El Nino current is the result of variances in the number and degree of sub-ocean volcanic activity taking places, which explains why none of the climate experts have been able to reliably predict when El Nino will occur.
In any event, El Nino is the result of natural processes and not human activity!
