President Donald Trump’s recent comments directed at North Korea have us all wondering if we’re slowly building up to nuclear war. While politics occupies most of that discussion, it’s worth knowing exactly what nuclear warfare would do to our planet, from the horrific impact to the prolonged fallout and famine the aftermath brings.
As it stands, there are nearly 15,000 nukes spread across nine nations. They are: The United States, Russia, The United Kingdom, North Korea, France, China, Pakistan, India, and Israel. According to tables and graphs from Business Insider and the Federation of American Scientists (FAS), Russia and the U.S. own a majority of the nukes available, and have also deployed the most throughout their respective histories—over 1,900 by Russia, and nearly 1,700 by the U.S. As for North Korea, it’s largely unknown how many nukes the country has, though The Washington Post reports the country may have around 60 nukes, and has managed to produce a miniaturized warhead capable of fitting inside of a missile.
Tactically speaking, U.S. nuclear warheads are designed less for maximum yield than for incisive accuracy. This includes bombs like the B61-12, with a yield of 50 kilotons. That is equivalent to 50,000 tons of TNT. The most destructive American bomb in service since October 2011 is the B83, with a maximum yield of 1.2 megatons (1,200 kilotons). By contrast, the bomb dropped on Hiroshima was 15 kilotons.
The FAS notes that, while numbers for the U.S. are based on “real” numbers, the statistics for the rest of the world are not as accurate. Most information related to a nuclear weapons are a widely held secret, and as such, it becomes difficult to know specifics about a nation’s military power.
The very idea of nuclear warfare is worrying enough on its own, but it becomes more terrifying when you realize how little it takes to affect the entire world. A 2014 study published in an American Geophysical Union (AGU) journal reveals that it would only take a small conflict between India and Pakistan to cause near-irreparable levels global devastation.
“A limited, regional nuclear war between India and Pakistan in which each side detonates 50 15 kilotons (kt) weapons could produce about 5 teragrams (Tg) of black carbon (BC),” reads the journal. “This would self-loft to the stratosphere, where it would spread globally, producing a sudden drop in surface temperatures and intense heating of the stratosphere.”
