The eruption of Mount Tambora is confirmed as the cause of the "year without summer"



In 1815, the Tambor Mountains volcano exploded into probably the largest eruption in the last 1500 years. It is often suspected that the event caused the so-called "year without summer" in Europe, as ash and sulfur dioxide blocked the sunlight. Atmospheric scientists, however, are unsure whether the explosion has contributed to the cold and wet conditions next year. Now climate models are used to show that Tambora has indeed caused record colds and probably humidity.

For the Indonesian people, the huge eruption of April 10 meant a tsunami that killed between 40,000 and 60,000 individuals, depending on your source. However, since the history of the era is mostly written in Europe and North America, the focus is on the possible amusing effect of these places.

The global average temperatures in 1

816 were 0.4º-0.7ºC (0.7º-1.3ºF) cooler than previous years. Rainy conditions are credited for giving Mary Shelley time to write Frankenstein, thus launching the entire science fiction genre.

Dr Andrew Schürer of the University of Edinburgh modeled what the year 1816 would be like without a volcano, using what we know about pre-eruption conditions and the sun's entrance. He says in environmental research letters that the eruption or no eruption, 1816. Europe may have experienced an unusually wet year, but it was the volcano that made it so cold.

"The inclusion of volcanic forcing in climate models can lead to cooling and we believe it increases the likelihood of extremely cold temperatures by up to 100 times," Schurer said in a statement. " Without volcanic violence, you were less likely to be wet and very unlikely to be cold. "[19659002] When it was a year without summer, people had no idea of ​​the reasons. The possibility of a volcano on the other side of the world to affect the climate is only the first time to be discussed after a similar cooling caused by the eruption of Krakataa in 1883. is associated with the year without summer in 1913 and has been widely accepted since the link has been established.

Nevertheless, it was noted that 1816 was at the end of an unusually low solar activity, sparking debate over whether Tambora represented the whole story, right now, sophisticated global climate models and the collection of proxies from around the world, we can address this in more detail.

Tambor emerged when food supplies were unusually vulnerable to a combination of the destruction of the Napoleonic wars and several summers cooled by small eruptions. Hundreds of thousands of people died in the ensuing famine.
