Volcanic winter: when to expect a new cooling due to the natural disasters

During the last week the volcanic activity on Earth has increased significantly, which could lead to serious climatic changes.

The well-known term "nuclear winter" implies a cooling due to the fact that dust particles raised by atomic explosions will prevent the penetration of sunlight to the planet's surface. But exactly the same thing occurs without any human intervention and with increased volcanic activity. In this regard, network analyst Dmitry Milin recalls several examples of this kind:

* 1991 - The eruption of Mount Pinatubo, Philippines (6 on the scale of volcanic eruptions) lowered the average temperature in the world by 0.5 degrees Celsius. Over the next months, a global sulfuric acid fog layer and an excessive reduction in the ozone layer, in particular, the formation of an especially large ozone hole over Antarctica, was observed in the atmosphere.

* 1912 - the eruption of the Katmai volcano, USA, Alaska (6 points) lowered the average temperature in the world by 0.4 degrees

* 1883 Krakatoa volcano eruption, Indonesia (6 points): 0.3 degrees

* 1815 - the eruption of the Tambor volcano, Indonesia (7 points) by 0.5 degrees. * The year 1816 was named "The Year Without Summer". The global average temperature dropped by 0.4-0.7 ° C, and in some areas by 3-5 ° C, enough to cause significant problems in agriculture around the world. On June 4, 1816, a severe cold snap was recorded in Connecticut, and the very next day most of New England was engulfed in a cold front. Snow fell on Albany, New York, and Maine on June 6. These conditions persisted for at least three months, causing severe damage to agriculture in North America. Canada has also been hit by extreme cold weather. In the Quebec region, snow fell from 6 to 10 June 1816, the thickness of the snow cover reached 30 cm.

* 1600 - The eruption of Huaynaputina volcano, Peru (6 points) lowered the average temperature in the world by 0.8 degrees. It caused great climatic changes during the so-called "Little Ice Age". In particular, it could have caused the Great Famine in Russia in 1601-1603, which contributed to the beginning of the Time of Troubles in Russia.

* 1257 - the eruption of the Rinjani volcano on the island of Lombok, Indonesia, is considered one of the reasons for the end of the small climatic optimum of the Middle Ages.

What about today? Here's what.

Карта вулканической активности

Volcanoes woke up in August:

Kilauea, Hawaii; White, N. Zeeland;

Ira, Ebeko, Japan;

Fuego, Santa Maria, both Guatemala;

Ibu, Semeru, Tenjer, all - Indonesia;

Kadovar, Langila, both - N. Guinea;

Reventador, Sangay, both Ecuador;

Taal, Philippines

Activity continues:

Merapi, Levotolo, both Indonesia;

Ebeko, Shirinkotan, both - Kuriles;

Suvanosejima, Fukutoku, both from Japan;

Shiveluch, Karymsky, both - Kamchatka; (Shiveluch intensified after the 8.2 magnitude earthquake that occurred on July 29, 2021 in the region of the Alaska Peninsula)

Semisopochny, B. Sitkin, Pavlov, all - Aleuts;

Pacaya, Guatemala;

Krisuvik, Iceland;

Volcanic activity on the planet has increased significantly over the week. The most active volcanoes are Shirinkotan, Fukutoku, Ebeko, Fuego, Semisopochny, Shiveluch, Suvanosejima and Taal.

However, not only volcanoes can provoke further cataclysms, but also fires. After the fires in Yakutia, which raised so much burning that the day became like night, calculations for the "nuclear winter" will also be quite relevant, and most likely a new cycle of a slight cold snap will be launched.
