With the economy in shambles and the United States, Europe, China and Russia vying for hegemony over global affairs, it is only a matter of time before the powder keg goes critical. Lines are being drawn.
People also seem to become happier as they get wealthier. But as you can see in the data, many important measures of progress have improved dramatically.
More to the point, no matter what you think has happened in the past, if we look forward, improving technology, political organisation and freedom gives our descendants the potential to solve our current problems, and have vastly better lives.
But also notice the purple line on the second chart: Each time we discover a new technology, most of the time it yields huge benefits. The first destructive technology of this kind was nuclear weapons.
We came near to nuclear war several times during the Cuban Missile crisis alone. The next day, a spy plane was shot down. JFK called the council anyway, and decided against invading. Some of the launch commanders in Cuba also had independent authority to target American forces with tactical nuclear weapons in the event of an invasion.
In another incident, a Russian nuclear submarine was trying to smuggle materials into Cuba when they were discovered by the American fleet. The fleet began to drop dummy depth charges to force the submarine to surface. The Russian captain thought they were real depth charges and that, while out of radio communication, the third world war had started.
He ordered a nuclear strike on the American fleet with one of their nuclear torpedoes.
Fortunately, he needed the approval of other senior officers. One, Vasili Arkhipov, disagreed, preventing war. Thank you Vasili Arkhipov.
And those are just the ones we know about. Nuclear experts today are just as concerned about tensions between India and Pakistan, which both possess nuclear weapons, as North Korea. This means that a false alarm or accident can rapidly escalate into a full-blown nuclear war, especially in times of tense foreign relations.
Would a nuclear war end civilisation? It was initially thought that a nuclear blast might be so hot that it would ignite the atmosphere and make the Earth uninhabitable. In the s, the concern was that ash from burning buildings would plunge the Earth into a long-term winter that would make it impossible to grow crops for decades.
How likely is a nuclear war to permanently end civilisation? That would mean the risks from nuclear weapons are greater than all the natural risks put together.

We now pose the greatest threat to our own survival — that makes today the most dangerous point in human history. How big is the risk of run-away climate change?

Jun 28, · North Korea is upgrading a major nuclear research facility despite President Donald Trump's claim that leader Kim Jong Un has vowed to disarm, according to . Mar 28, · The recent attacks in Belgium and elsewhere would have been catastrophic if the terrorists had gotten their hands on nuclear weapons or even a primitive “dirty bomb,” which combines nuclear.
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).Both bomb types release large quantities of energy from relatively small amounts of matter.
The first test of a fission ("atomic") bomb released an amount of energy approximately equal to.

The nine nuclear-armed nations spend many tens of billions of dollars each year maintaining and modernizing their nuclear arsenals.
Funding allocated to disarmament efforts is minuscule by comparison.
