Like most media coverage, the article omits the primary cause of the recent acceleration in warming - desulphurization of ship fuel “ the IMO2020 fuel change cut cloud tracks in key shipping lanes by half...this has a substantial effect on warming, concentrated in areas with heavy shipping activity like the North Atlantic. The reduction in reflective cloud cover over this region, plus an unrelated reduction in reflective airborne dust levels, can account for most of the warming observed in the North Atlantic” https://www.maritime-executive.com/article/low-sulfur-fuel-rules-may-have-contributed-to-record-ocean-temps https://www.maritime-executive.com/article/low-sulfur-fuel-r...

While that does have an effect, the record temperatures are not only located on the northern Atlantic, but on the whole planet

  It's questionable how much the Tonga eruption which sent an 'Unprecedented Amount of Water Into Stratosphere' has had on the climate. Some temporary warming was certainly predicted and this would be global.

Does this change anything? It is the warming that is harmful, not the cause of it.

  Yes, this change is reversible https://caseyhandmer.wordpress.com/2023/06/06/we-should-not-let-the-earth-overheat/ https://caseyhandmer.wordpress.com/2023/06/06/we-should-not-... “How do we keep the world cool for the next few decades while we upgrade our industry to a post-carbon world and scale up CO2 removal? It does us no good to be stable at 350 ppm by 2060 if we’ve already lost Greenland, the West Antarctic ice sheet, and 7 m + 4 m of coastline respectively”

Yes, and we need to start putting that sulfur or something equivalent up there again as soon as possible. This is textbook geoengineering and people are wary of it because once you start with it, the environment becomes dependent on it to maintain balance. And like with someone addicted to a drug, there will be withdrawal symptoms if you stop abruptly. It's really funny that we've been doing it all along but never realized it.

Partial cause but not primary. The largest kick to recent activity has been the El Niño–Southern Oscillation (ENSO) swing. Expect high temps for a few years and then some slight relief before things rachet up again.
