The use of bombs and other explosive weapons in warfare has a devastating impact on the environment, causing both immediate and long-term pollution. From the atmospheric nuclear weapons tests of the 1940s to the more recent conflicts in Iraq and Ukraine, the release of hazardous pollutants and the destruction of ecosystems have had far-reaching consequences for public health and the planet. Even a limited nuclear exchange could release millions of tonnes of CO2, while the detonation of a single nuclear bomb can produce enough energy to kill millions of people and contaminate the surrounding environment with radioactive fallout. As the world continues to urbanize, the use of explosive weapons in populated areas poses an increasingly dire threat, with civilians bearing the brunt of the environmental and health impacts.

What You'll Learn
Nuclear bombs produce radioactive pollution
Nuclear weapons are the most destructive, inhumane, and indiscriminate weapons ever created. They produce radioactive pollution, which has devastating consequences for the environment and public health.
Nuclear explosions release vast amounts of energy in the form of blast, heat, and radiation. When detonated aboveground, nuclear weapons send radioactive materials as high as 50 miles into the atmosphere. The particles that are swept into the atmosphere are called fallout. Fallout typically contains hundreds of different radionuclides, which can stay in the environment for a long time due to their long half-lives. For example, cesium-137 has a half-life of about 30 years. These particles can circulate around the world for years until they gradually fall to Earth or are brought back to the surface by precipitation.
The health risks from fallout are significant. Radionuclides that are inhaled or ingested interact with internal cells and tissues, increasing the risk of harmful health effects. They can change the structure of cells, which is one way that people can develop cancer. Physicians project that about 2.4 million people worldwide will eventually die from cancers due to atmospheric nuclear tests conducted between 1945 and 1980.
Even the production of nuclear weapons has an effect on the environment. Producing the explosive materials used in nuclear weapons leads to long-lasting radioactive pollution. The detonation of thousands of nuclear weapons could result in a nuclear winter, destroying the essential ecosystems on which all life depends.

Nuclear explosions release energy in the form of blast, heat and radiation
The use of nuclear weapons has a significant impact on the environment, both in terms of radioactive pollution and climate disruption. The production of nuclear weapons and the testing of these weapons has already had an effect on the environment. Atmospheric nuclear weapons testing, which began in the 1940s, produced unusual isotopes in the atmosphere, including 14C. This caused an increase in the ratio of 14CO2 to total CO2 in the atmosphere. By the 1980s, most of the "bomb" 14C had been absorbed into the oceans and land biota, and atmospheric 14C levels have since decreased due to the exchange of CO2 with the ocean and land biota.
Nuclear explosions release energy in the form of blast, heat, and radiation. The blast effect is created by the coupling of immense amounts of energy, spanning the electromagnetic spectrum, with the surroundings. The environment of the explosion determines how much energy is distributed to the blast and how much to radiation. For example, surrounding a bomb with denser media, such as water, absorbs more energy and creates more powerful shock waves while limiting the area of its effect.
The temperatures reached in a nuclear explosion are much higher than in a conventional explosion, and a large proportion of the energy is emitted as thermal energy in the form of light and heat. This thermal energy is capable of causing skin burns and starting fires at considerable distances. It can also cause incendiary effects, such as secondary fires started by the blast wave effects, and can ignite materials outside the protective shadow of opaque objects. Additionally, if fog or haze is present at the point of the explosion, the radiant energy can reach burn-sensitive substances from all directions.
Nuclear explosions are also accompanied by various forms of radiation, which can last from a few seconds to an extended period. Radiation from a nuclear explosion can negatively impact both workers and public health, potentially leading to acute radiation syndrome with symptoms including skin burns, vomiting, diarrhea, and possibly coma. The radiation released by a nuclear explosion can also cause genetic damage and long-lasting radioactive pollution, contaminating areas and making them uninhabitable for physicians and first responders.

Nuclear weapons testing increases atmospheric carbon levels
Nuclear weapons testing has a significant impact on the environment and contributes to the increase in atmospheric carbon levels. The production and use of nuclear weapons result in long-lasting radioactive pollution, affecting the climate and endangering human lives.
The excess carbon 14 from nuclear testing has far-reaching consequences. It has been absorbed by the oceans and land biota, leading to elevated levels in the environment. This has impacted radiocarbon dating methods, requiring the adoption of reference standards to account for the artificial radiocarbon. Additionally, the widespread use of nuclear weapons in atmospheric testing has caused long-term health issues, with an estimated 2.4 million people projected to die from cancers due to atmospheric nuclear tests.
Moreover, the development and use of nuclear weapons carry opportunity costs in terms of carbon emissions. The planning and construction of nuclear stations and weapons material contribute to carbon emissions, and the risk of nuclear conflict increases with the dissemination of nuclear energy facilities. Even a limited nuclear exchange could release a significant amount of CO2 into the atmosphere, causing climate disruption and threatening global food security.
Nuclear weapons testing and conflict have severe environmental and humanitarian consequences, including the release of radioactive fallout, disruption of ecosystems, and the potential for a nuclear winter. The energy released by nuclear explosions is immense, and the impact on the climate and human civilization can be devastating. Therefore, it is crucial to address the environmental costs of nuclear weapons development and testing to mitigate the risks associated with carbon emissions and radioactive pollution.

Explosive weapons in populated areas cause air and water pollution
Curtailing the use of explosive weapons in populated areas is a humanitarian priority due to the increasing number of civilian deaths and injuries from armed conflict in urban settings, as well as their indirect environmental impacts. The use of explosive weapons in populated areas causes harmful pollution and destruction, which constrains access to the environment civilians live in.
Secondly, explosive weapons can leave behind Explosive Remnants of War (ERW) in the debris, which can contain toxic substances. These remnants can pollute the environment and affect the health of civilians, as well as hinder stabilization efforts by preventing displaced people from returning to their homes.
Thirdly, the use of explosive weapons in populated areas can generate huge volumes of debris and waste, as well as release hazardous materials such as asbestos, industrial chemicals, and fuels. This can further contaminate land and water sources, impacting the environment and human health.
Finally, conflict pollution caused by explosive weapons can have serious acute and long-term health risks for populations. It can hinder access to clean water, worsen the spread of communicable diseases, and result in toxic coping strategies for energy production. The environmental impact of explosive weapons can also affect the long-term recovery of communities, as their livelihoods may depend on environmental resources.
