It's time to go geoengineering on climate issue

This is the second anniversary of the arrival of the emergency but practically nobody is mentioning it. Instead people are choosing to worry about more familiar problems like global trade wars, the rise of fascism and genocidal wars. It's kind of a global displacement activity: if we don't mention it, maybe it will go away.

Two years ago this month (June 2023) the average global temperature jumped by a third of a degree Celsius in a single month. That shook the climate science world to its foundations, because the orthodox predictions assumed about one-tenth of a degree of warming every five years.

The June 2023 event was "non-linear". Like most major shifts in natural systems, the pressure built up and up, and then suddenly the system flipped into a different stable state. It took more than another year until last December to figure out what actually happened.

Ninety percent of the extra heat in the atmosphere from burning fossil fuels goes straight into the ocean. That heat was bound to affect the ocean currents, and sooner or later one of those currents would start returning very warm water to the surface.

The water gave up its heat to the air and suddenly, two years ago, the low-level clouds over the eastern North Atlantic started to thin out, letting in much more sunshine to warm the ocean's surface. This chain of events, where the warming we cause triggers further changes in the climate, is called a "feedback" and since we didn't cause it directly, we can't turn it off.
