The strangest summer in recorded history
the strangest summer ever
It is now April 10, 1815, and the day will soon be gone. The rumble of the eruption of Mount Tambora on an island off the coast of Indonesia can now be heard more than 2,000 kilometers away. Plumes of sulfurous fumes and ash shot thousands of meters into the sky, creating a dark storm cloud of spray and lightning. The eruption was the largest on record, but the impact was just beginning. Tambora rose into the air and spread across the globe, blocking the sun for an entire year. The dark and cold weather of 1816 had a devastating effect on agriculture, and famine spread across the northern hemisphere. As countries battle the pandemic, artists are hailing this seemingly apocalyptic era. It was a year without a summer—one of the darkest periods in human history.
So why are some current researchers looking for ways to replicate it? Of course, no one wanted to repeat the hunger and misery of this time. But some scientists want to use sulfur dioxide to block the sun and delay the effects of global warming. It is one of the many applications in the field of geoengineering, a very important intervention in the Earth's natural systems designed to help climate change. Different geoengineering options involve different systems. Plans to cool the earth by blocking sunlight from reaching the earth fall under the umbrella of solar radiation management. Some of the applications are large, such as the idea of creating a practical version of volcanic eruptions or creating a large shield in Earth's orbit. Others are smaller and focus on improving natural cooling systems. For example, researchers can expand ocean clouds or change the world to reflect more sunlight by creating white surfaces. Most of these plans are strange. But there is reason to believe that this method may be effective, especially due to natural phenomena such as the Tambora eruption.
Scientists know that periodic eruptions tend to cool down. The eruption of Mount Pinatubo in 1991 and the eruption of Krakatoa in 1883 dropped the average global temperature by half a degree Celsius for one year. The effect of this warming is global and fast, but the risks are very high. The earth is a chaotic system, and even the smallest changes can cause many chain reactions. We know that lower temperatures will affect precipitation, extreme weather and other weather conditions, but even the most sophisticated computer models are difficult to predict how or where these effects will occur. . The management of solar radiation in one country can be a disaster in another, bad weather or unproductive, as after the eruption of Tambora. Even if these plans succeed in effectively cooling the world, controlling solar radiation will not solve the greenhouse gas problem that contributes to global warming.
These solutions are only trial-and-error solutions that the world will have to work on for at least a few decades while we work to completely remove carbon dioxide from the atmosphere. If the Band-Aid is removed too quickly, global temperatures will rise again quickly, leading to a period of extreme heat. Therefore, controlling the sun's rays is problematic. Currently, researchers are conducting small-scale experiments, such as adjusting oceanic clouds to protect the Great Barrier Reef from warming and warming. Most scientists agree that we must first find ways to reduce emissions and remove carbon dioxide from the atmosphere. However, there is reason to continue investigating this intriguing approach. Hard times call for action, and in the future, geoengineering may be the world's last resort. In addition, some of these schemes are very easy to be carried out by bad actors who have a lot of money. So we need to be prepared if people start doing geoengineering without government approval. But perhaps the most important reason to investigate the effects of geoengineering is that humans are already entering the atmosphere on a large scale. In many ways, climate change is an unplanned geoengineering project driven by emissions from centuries of burning fossil fuels. If we don't act quickly to reduce emissions and remove carbon dioxide from the atmosphere, summer may not be the same.

Ancient Rome
- [Narrator] The story of ancient Rome is a story of evolution, and the world's ability to adapt and survive for over 1,000 years. Rome began as a small village on the Tiber River in central Italy. Over the next few centuries, the country grew into an empire stretching from the North Pacific to the Persian Gulf. During this transition, Rome demonstrated political, military, and cultural power that became a great power and helped shape the Western world. The history of ancient Rome can be divided into three main periods: the imperial period, the republican period, and the imperial period. During the Imperial period, Rome was a monarchy, ruled by seven kings. According to legend, the first king of Rome was a man named Romulus. He and his twin brother Remus are said to have founded Rome in 753 BC. In 509 BC, Rome adopted a republican form of government, in which the country was governed by two annual representatives, known as orators and later orators. One of them was the famous general and diplomat Julius Caesar. Next is the Imperial period. It was marked by the rise of the Roman Empire and famous leaders such as Octavian, the first Roman emperor, who came to the throne in peacetime, and Nero, who was made the some scholars are the most corrupt emperors of Rome. Rome's importance and pride in its soldiers was essential to the development of its world, a need that was evident from the beginning of the Empire when Rome was a small village. Despite this, Rome conquered its neighboring countries. In the end, this rapid growth reached the Roman rule in the Italian peninsula and the entire Mediterranean, where they conquered Greece, Egypt and Carthage. Later Rome helped the military conquer territories as far as England and Iraq. The sheer size and growing population required advances in Roman technology. Aqueducts were built, increasing people's access to water, helping to improve public health and paving the way for the famous Roman baths. A 50,000 mile road system was also built. Although originally designed for the military, it facilitated the movement of people and ideas throughout the empire. The spread of ideas and increased contact with different cultures allowed other aspects of Roman culture to develop. The key to Rome's success and longevity was the empire's acceptance of the cultures of the regions it conquered. Rome received Latin from the neighboring country of Latium, where it became the official language of the kingdom and the ancestor of the Romance languages of Europe. The Romans also absorbed the culture of the ancient Etruscan states, including religion, the alphabet, and aspects of gladiatorial combat. However, no other nation was as powerful as the ancient Greeks. Their influence can be seen in Roman art and architecture. The Roman upper class commissioned paintings and statues modeled after Greek art. Greek architectural styles, such as columns, were used in Roman buildings such as the Pantheon and the Colosseum. The rise of Christianity was a cultural change that had great influence throughout the empire. This religion originated in the Middle East and received strong support from Constantine I, the first Roman emperor to convert to Christianity. He transformed Rome into a Christian state and encouraged the spread of the religion throughout Europe. In the fourth century, the Roman Empire fell after more than a thousand years of existence. Factors such as political corruption, economic crises, and class wars caused empires to collapse from within, while invasion and other military threats caused empires to collapse from without. Rome's ability to unite diverse cultures, dominate its rivals, and tailor its political system to the needs of its people is a lesson to be learned forever.
