This is part of an article in new scientist magazine: Our research indicates there were no mountains and continental collisions during Earth’s first 700 million years or more of existence – it was a much more quiet and dull place,” he says. “There are strong similarities with zircon from the types of rocks that predominated for the following 1.5 billion years, suggesting that it took the Earth a long time to evolve into the planet that we know today.” The team conducted a forensic study of the grains looking for clues to their formation. They found that the zircon was created by melting old igneous rocks rather than sediments. “Sediment melting is characteristic of major continental collisions, such as the Himalayas, so it appears that such events did not occur during these early stages of Earth’s history,” says Burnham. Well, this is no news, was in the first chapter of genesis. So no surprises here. This is the link of the article, if you want more information: https://www.newscientist.com/article/2130266-early-earth-was-covered-in-a-global-ocean-and-had-no-mountains/

Well, is evident that almost all american scientist are against Donald Trump, so scientist are very involved in politics affairs. In an article of the new york times explains the point of view of the bulletin scientist: There were crises that the clock was not quick enough to take into account. The Cuban Missile Crisis, for instance, in 1962, did not change the hands of the clock, which at the time stood at seven minutes to midnight. An explanation on the Bulletin’s website accounts for this seeming lapse in timekeeping: “The Cuban Missile Crisis, for all its potential and ultimate destruction, only lasted a few weeks,” it says. “However, the lessons were quickly apparent when the United States and the Soviet Union installed the first hotline between the two capitals to improve communications, and, of course, negotiated the 1963 test ban treaty, ending all atmospheric nuclear testing.” The end of the Cold War came as a relief to those who had lived in fear of nuclear annihilation for decades, and the minute hand slowly moved away from danger. In 1990, it was at 10 minutes to midnight. The next year, it was a full 17 minutes away, at the relatively undisturbing time of 11:43.“The illusion that tens of thousands of nuclear weapons are a guarantor of national security has been stripped away,” the Bulletin said at the time. But over the next two decades the clock slowly ticked back. Conflict between India and Pakistan, both of whom staged nuclear weapons tests three weeks apart, had the clock at nine minutes to midnight in 1998. By 2007, fears about Iranian and North Korean nuclear capacity had pushed it to 11:55. By 2015, the scientists were back in a state of unmitigated concern, with the clock at three minutes to midnight, the closest it had been since 1984. “Unchecked climate change, global nuclear weapons modernizations, and outsized nuclear weapons arsenals pose extraordinary and undeniable threats to the continued existence of humanity,” the bulletin said. “World leaders have failed to act with the speed or on the scale required to protect citizens from potential catastrophe.” “These failures of political leadership endanger every person on Earth,” it added. the article is here: https://www.nytimes.com/2017/01/26/science/doomsday-clock-countdown-2017.html?_r=0 And this is an article about how an soviet submarine almost cause an catastrofe in the last day of the cuban missile crisis http://www.dailymail.co.uk/news/article-2208342/Soviet-submariner-single-handedly-averted-WWIII-height-Cuban-Missile-Crisis.html

Thanks Shawnster for explaining what is the significance of the doomsday clock. Efectively not only the situacion in Corea is reponsible for the time that this clock was set, but other factors, that you are mentioning. Is interesting that the new york times, about a month ago, was speaking of the situation between India and Pakistan, and how India was considering a preventive nuclear strike; the article mentios that a limited nuclear conflict between India and Pakistan can result in a billion deaths due to the efect of the nuclear winter, and the efect in the crops, that can be devastating . A limited nuclear conflict with north corea can have very bad consecuences.

Gracias Carlos, ya que hace tiempo que no nos vemos, nos leeremos por aqui

Well, this is a few days old, but the article is very interesting. This is the time that the Doomsday clock is set actually. The reasons? This is a paragraph of the article appearing in new scientist TWO and a half minutes to midnight. That was the time the Bulletin of the Atomic Scientists set their Doomsday Clock to just a few months ago – later than it has ever been except between 1953 and 1960, the height of the cold war H-bomb race. Among BoAS’s concerns were bellicose sentiments from Donald Trump and North Korea’s efforts to make its own nuclear weapons. the original article was here: https://www.newscientist.com/article/mg23431223-300-talk-of-a-localised-nuclear-conflict-is-ignorant-and-dangerous
