On December 5, 1952, the world’s romance with London’s fog ended in disaster. The real extent of wich was never being acknowledged. Air pollutants from the use of coal, combined with an anticyclone, windless condition and cold weather, formed a thin layer of smog over the city of London.

Cold weather for London’s residents meant the increasing need to burn more coal then usual to keep warm in houses. The coal people were using was an inferior quality as the government focused on exporting the good quality coal to pay off his depth. The low-grade coal increased the sulphur dioxide in the smoke that added to the coal-fired power station in London increased the level of pollution.

The anticyclone settled over London one day before the disaster and caused a temperature inversion, the cold air being trapped under a layer of warm air.This has resulted in a dense fog wich mixed with the chimney smoke, vehicle exhausts and other pollutants filled with sulphur, formed a persistent smog. Also, the absence of the wind prevented the smog to be dispersed.

At the time of the event, it wasn’t considered a significant event, even if it caused major disruption due to the effect of visibility. Continue reading The Great Smog of 1952

In August 1945, after four years of World War II, United States B-29 bomber, dropped the atomic bomb over the cities of Hiroshima on August 6th, 1946.

70.000  people died in 9 seconds, and the city of Hiroshima was leveled. 3 days later a second bomb was dropped  Nagasaki, Japan with the same devastating results. The bombing killed over 129.000 people.

This is the only use of a nuclear weapon in the history, and the justification of the bombing is still debated. It was the most devastating bomb that humanity invented

The bomb released a cataclastic load of energy. Death was instant. The ones who were close enough to see the blast lost their eyes. It was the last thing they ever saw.The bright light of the blast blinded them. The black of their eyes, the retina, melted away. The radiation received by the body is equivalent of today’s thousands of X-rays. The human body can’t absorb unlimited radiation. It falls apart because the cells are dying of radiation poisoning. If the radiation is intense enough, it looks like a burn. Layers of the skin begin to fall off. The bodies vital function began to slow down until it stops.
