Fire causes frost
Scientists now prove that terrible volcanic eruptions cause the Earth's atmosphere to become cold, polar and frozen mountains, lower ocean levels and people who have to migrate to near the region. equator to avoid perdition.
In 2008, the greenhouse gas emissions increased sharply, making the Earth's temperature higher, the weather becoming hot. 16.2 billion tons of carbon dioxide (CO 2 ) and 12.2 million tons of methane (CH 4 ) are released into the atmosphere during the year.
Pinatubo Mountain erupts on June 15, 1991
But in the years 1991-1993, after the spill of Pinatubo volcano (north of Manila, Philippines), the global temperature dropped by more than 0.5 o C and the amount of carbonic (the main component of greenhouse gas) did not increase. Researchers found that volcanic sputtering is a natural factor balancing the phenomenon of global warming. As the sun declines, plants respond by restricting respiration (high CO 2 emissions) and increasing photosynthesis (absorbing CO2 in the air).
16g on June 15, 1991, the Pinatubo mountain exploded, sending a 60-kilometer high pillar of smoke into the sky. Dust ash spread into the upper atmosphere and then circled the Earth. About 14-26 million tons of sulfur dioxide (SO2) gas, which turns into sulfuric acid cloud (H 2 SO 4 ), prevents sun rays and makes the atmosphere cold for many years. When seawater cools, the volume of shrinkage is reduced, the sea level immediately drops to about 5 mm immediately after the occurrence of the extract.
In 1815, the tops of Tomboro in Indonesia's volcanic arc shot up to 160 km 3 of dust and smoke, causing the Earth's temperature to drop to 3 o C, many places where snow fell right in the middle of the summer and consecutive crops failed, famine was widespread.
Santorini volcano shot the middle of the big island
Terrible volcanic eruptions are always accompanied by historical fluctuations, not by direct impact but by climate change. The Mataram Empire in Java disappeared after the Merapi volcano erupted in 1008. The South American Mayan civilization disintegrated around the 300s following the Ilopango explosion. And the great civilization of Minoan waned when Santorini island exploded in 1610 BC, now leaving fringes to form a beautiful archipelago of the Mediterranean.
Toba volcanic lake is 100km long, 30km wide
But the most important explosion involving human survival occurred 70,000 years ago. At that time, Toba tops the sky about 800 km 3 of rock, a relic is a volcanic lake 30km x 100km north of Sumatra, very close to Vietnam. The layer of ashes painted thick on many continents, on average 1-3m, in places of 6m, in the Mekong Delta from 0.2-0.8m.
Immediately after the Toba explosion, the world experienced an ice-cold winter that lasted for six years and the global climate continued to be severely cold for more than 1,000 years. Humanity disappears, only groups of people hiding in warm sub-regions exist and proliferate to this day.
