“Geologist [I'm Climate Change]”

Interesting article but aside from the 5 years after the Pinatubo & the Cerro Hudson events (1991), the net cooling from volcanic eruptions has been negligible as the yearly tally otherwise has been @ tickover rates typical of years before and since the 1990s.
The true agent of global cooling has in fact been a change of climate mode due to oceanic warming.
Prior to 1984 the climate mode was predominantly the Jason model climate mode#2 which is beloved of the climate change politicians such as Al gore & others on both the pro & anti side of the debate.
Post 1984 the global temperatures became high enough to precipitate a change to the more efficient climate mode#3. This mode is much more efficient @ cooling the planet but as the Earth is just @ the tipping point, the mode has been switching on & off like an aircon thermostat, with global temperatures levelling out.
We are now approaching solar max & mode#3 is ON with as a result unmodelled weather chaos to live in (remember that?). We are also in la Nina conditions due to prodigious icemelt from the antarctic shelves.
Volcanism is not the cause of the current hiatus in the rate of global warming.
Have a nice day: Ag
