Can somebody explain this part?
> By cleaning up shipping fuels, massive regions of the world’s oceans that were protected from heating by shipping sulfate aerosols are now experiencing rapid warming. This includes the main shipping routes between Asia and the Western US as well as the major routes from the Easter US to Europe and the Middle East. And that’s where the warming is happening. This rapid heating is known as “termination shock,” and it appears to be what’s happening right now.

When people speak of geoengineering, they are referring to intentionally spraying these elements (sulfur) into the atmosphere to reflect more of the sun's energy and temporarily cooling the earth. However, the problem with this system is that the second you stop, you get a huge bump in temperature. Like a whip, you get a quick increase. Turns out, the shipping industry may have been inadvertently geoengineering and now that there are regulations on the amount of sulfur expelled, we may be experiencing that snap to warmer temperatures. You may think "Let's just spray some sulfur of our own," but there are unintended consequences associated with it. In my mind though, the biggest issue is that without a reduction in emissions, you'll need more and more sulfur sprayed into the atmosphere and eventually it will not be effective. Supposing you've continued to emit all that time and are still emitting, then the snap would be even greater.
