First and foremost, this rise CANNOT be tied to the dogma of the day: AGW. There was no anomalous-increase in atmospheric CO2 in July, or in any prior month, to justify such an uptick. July’s spike is a naturally-driven event — this is widely agreed upon.
And although the explanations behind this temperature increase are lacking, and the forcings involved poorly understood –due in no small part to today’s climate science coffers funding AGW-affirming theories only– a change in ocean currents, atmospheric winds, and the infamous Hunga Tonga eruption of Jan 15, 2022 appear top of the list.
Hunga Tonga, being a submarine volcano, fired excessive amounts of water into the atmosphere. Some postulate that this vapor, after an initial cooling lag, is now exerting a temporary warming effect — water vapor being Earth’s most abundant GHG.
There doesn't seem to be anything here yet
