I was referring to reply #2133 above.

I wrote because the estimate of cooling due to aerosols at 2 degrees is not confirmed by the official figures. After 2005, SO2 emissions decreased by 2 times, and the global temperature has increased by about 0.2 degrees Celsius since then.

You cannot use global temperatures like that.
They are composed of many inputs so they do not tell you anything about the SO2 unless you know all the other stuff but we don´t.

PS: Tom i went to see what he said about the 1,9 but it is just in a graph. And probably it is just some total which is not valid for the period. I have no data to back that up but the text above the graph states: many doubt that there will be any life left on Earth by 2026.

You should be able to recognize that people that write drivel like that do not help and probably not produce the best graphs.

Some of the local effects the pollution has:
https://www.scientificamerican.com/article/tug-of-war-between-air-pollution-and-co2-masks-warmings-impacts/

Can be compared with other important climate indicators:

CO2 from 380 to 410 ppm +7%
CH4 from 1770 to 1870 ppb +5%
N2O from 319 to 332 ppb +4%
SF6 from 5.5 to 10 ppt +45%
global sea ice extent from 22 to 21 million km2 -5%

Of these figures, comparable changes with SO2 occur only with another sulfur compound (SF6 or Sulfur Hexaflouride). Only it, on the contrary, heats, not cools (the strongest known greenhouse gas is 24 900 times stronger than carbon dioxide). In general, it seems that sulfur compounds continue to play a crucial role in climate measurements, which is not surprising. After each strong eruption of the volcano, there was always a strong short-term cooling.

The difference between 2016 and 2019 on today decreased to 0.007 degrees Celsius.

A month ago it was 0.04 degrees Celsius.

2016: Average temperature +0,583 С to norm 1981-2010 years

2019: Average temperature +0,576 С to norm 1981-2010 years

2019 could be a record warm year despite the neutral phase of Pacific oscillation.


December is rapidly warming in the forecasts. Without 20 days, 2019 is already ahead of 2016 by 0.004 degrees Celsius.

2019: Average temperature +0,587 С to norm 1981-2010 years

Without 14 days, the superiority of 2019 over 2016 rose to exactly 0.1 degrees Celsius.

Reanalysis puts daily GMST anomalies at around the highest values of the entire year of 2019.
