Research into what are some warming/cooling events/regions

[beefoo]

By looking at the global and regional temperature records, see if we can identify specific climate events that we can call out, e.g.:

• Cooler-than-usual or warmer-than-usual set of years
• Various regional heat waves
• Specific historical markers of significance (e.g. various periods industrialization like WW2)

Dip between 1940 to 1970 can be explained by aerosols emitted by industrial activities and volcanic eruptions: https://www.newscientist.com/article/dn11639-climate-myths-the-cooling-after-1940-shows-co2-does-not-cause-warming/

The Mt. Agung eruption in March 1963 produced a decrease of about 0.5°C in the mean temperature of the tropical troposphere

Clean air act of 1970 reduced aerosol emissions, thus warming effects of GHGs slowly outweighed cooling effects of aerosols

Three largest volcanos of the 20th century seem to align with short-term cooling

Santa María Volcano in 1902 Mt Novarupta eruption of 1912 Mt Pinatubo of 1991

Bonus: Mt St Helens of 1980

These should also be annotated in the warming-factors section

Strong El Nino contributed to 1940-1942 warming
