We know that extraordinary weather events can occur depending on specific conditions. A catastrophic volcanic eruption could have repercussions on the global climate. The famous Year Without a Summer of 1816 provided a perfect opportunity to reflect on which aspects of the planet can seriously affect our climate. If you would like to learn more about this phenomenon, you can visit our page about the Year Without a Summer.
In this article we are going to tell you everything you need to know about the year without summer and how some situations affect the world climate.
A year without a summer
Due to the eruption of Mount Tambora, a volcano located in Bagua, between April 5 and 10, 1816, immense clouds of dust and ash were released into the atmosphere. More than 12.000 people died in the first 24 hours , primarily from ashfall and pyroclastic flows. Following this, another 75.000 people died from hunger and disease in the aftermath of this eruption, the largest in 2.000 years.
As one of the world's largest eruptions, it emitted millions of tons of volcanic ash and 55 million tons of sulfur dioxide, which rose to a height of 32 kilometers in the atmosphere . Despite being a localized eruption, strong winds carried the dispersing plumes westward. This meant that everything emitted by the volcano circled the Earth in just two weeks.
Two months later, these currents reached the North and South Poles. The extremely fine sulfur particles remained suspended in the air for years. In the summer following the eruption, an almost invisible veil of ash covered the entire planet. This translucent layer reflected sunlight, preventing its rays from reaching the surface and causing a global temperature drop. It also caused widespread climatic disruption. This is why the Year Without a Summer occurred in 1816. For more information on similar events, check out our article on the most devastating natural disasters.
It is not any kind of divine revenge as was thought at that time, but the most serious eruptions of a volcano. This causes the climate to cool by several degrees for years.
Impact of a year without a summer
The full impact of the global cooling was a consequence of the Tambora cataclysm, but it wasn't felt until a year later. Clouds of water droplets dispersing in the stratosphere reduced the amount of solar energy reaching Earth. The air, the land, and then the oceans all cooled. This phenomenon was well documented by studying the growth rings of European oak trees. This study confirms that 1816 was the second coldest year in the Northern Hemisphere since 1400. Evidence of this climatic anomaly is well-documented in our article on the driest summers.
As summer and fall rolled on, the cloud spawned spectacular red, purple and orange sunsets over London. It can be said that the sky had fire in some places. In the spring of 1816 there will still be snow in the northeastern United States and Canada. The cold also reached Tennessee and the freezing weather lasted until June. Such were the low temperatures that in some places like New Hampshire it was practically impossible to plow the land.
This month, the air was quite cold, and tremendous storms struck, freezing many birds to death in the streets just two weeks before the summer solstice. Many crops withered in the fields due to severe frosts. Numerous flocks of sheep also perished from the cold. This was a time when there was no serious meteorological science and no way to predict the weather.
In the absence of science, the devotees made all storms were caused by God made a symbol of divine wrath. Europe also experienced very low temperatures and a colder and wetter spring than normal. Due to the high price of the baron, there were various disturbances in France.
Consequences
Numerous studies have been conducted on the Year Without a Summer, primarily based on the analysis of European oak rings. These rings indicate that 1816 was the coldest year since 1400. Tensions among residents increased. Intense cold and drought devastated hay and corn crops in many areas, with winds typical of October occurring in August. Europe experienced constant rain and heavy snowfall, particularly in the Swiss mountains. This caused rivers and streams to overflow.
The peasant houses began to work urgently to save the vegetables and all the hay was transported soaked in boats. It was the only way to save crops as much as possible. In Germany the potatoes ended up rotten in the land gate of the storms ruined most of the crops. The cereal harvests were also allied, the grapes did not ripen in the vineyards and I saw them almost every day for 5 weeks in a row.
In Paris, some church authorities ordered nine days of special prayers to try to get God to end the bad weather. Merchants throughout Europe raised prices, while the anxiety of the poor reached alarming levels, all in anticipation of poor harvests. In both Spain and Portugal, the cold persisted, with average temperatures 2-3 degrees below normal.
They were especially abundant precipitations in the month of August, being men generally dry. The cold and humidity ended up damaging crops throughout the country. A sky watcher noted that in the entire month of July there were only 3 cloudless days. The cold temperatures ended up killing the fruits, especially the grapes, because I only made a small proportion of the harvest. This produced poor quality wines. Olive trees are also sensitive to cold and heat and did not produce quality fruit either.
In short, it was quite a disaster caused by a large-scale volcanic eruption. I hope that with this information you can learn more about the year without a summer.
