Mad Scientists Theorize That We Need A Little “Nuclear Winter” To Cure “Global Warming”

Global Warming Gives Science Behind Nuclear Winter a New Purpose

Carl Sagan and other Cold War scientists once feared that a nuclear war could plunge the world into a deadly ice age. Three decades later, does this theory still resonate?

With global temperatures rising inexorably, some scientists and national security theorists have pondered cooling things down by tinkering mechanically with the planet’s climate.

The goal of this geoengineering would be to create an effect not unlike when clouds suddenly block the sun and chill a warm afternoon. Average surface temperatures might be held down by a few degrees worldwide, these experts suggest — enough, they theorize (maybe with fingers crossed), to stave off environmental cataclysm.

How to do this? With smoke and mirrors. For real.

One idea is to launch giant mirrors into space, where they would bounce back some of the sun’s energy. Another suggestion involves spraying ocean water into the air to whiten clouds and thereby increase their capacity to deflect sunlight. Then there is a widely discussed plan to pump sulfate aerosols into the stratosphere. Those particles, too, would reflect the sun’s radiation back toward space, comparable to the effects of natural phenomena like volcanic eruptions. The haze created by the eruption of Mount Pinatubo in the Philippines in 1991 spread so widely that average global temperatures dropped by nearly one degree for more than a year.

Let’s set aside these proposals for a moment to first note that the aerosols plan faintly echoes a terrifying scenario that informs the latest offering from Retro Report, a series of video documentaries that study the continuing impact of major news stories of the past.

In the 1980s, fears took hold that a war-prone world lived in the shadow of catastrophic global cooling, a potential disaster called nuclear winter. Perhaps no one was more effective in warning of the peril than the astronomer and science communicator Carl Sagan, who died in 1996. In 1983, Dr. Sagan and four other scientists published their conclusion that an all-out nuclear war, presumably between the United States and the Soviet Union, could doom humankind. The horror would go well beyond the immediate devastation of cities and mass deaths in the hundreds of millions. What would follow would be a winter so severe that the living might well envy the dead.

With forests and scores of cities set ablaze, enough dust and smoke would be hurled into the upper atmosphere to blot out the sun. The darkening would last for many months, most oppressively in the Northern Hemisphere, though the Southern Hemisphere would hardly be immune. Beneath the sun-blocking canopy, surface temperatures would plummet, conceivably by as much as 60 degrees Fahrenheit. Plant and animal life would die. Famine would spread across the globe.

Climatic change could become climactic change. In the ominous concluding words of a paper published in the journal Science in December 1983, “the possibility of the extinction of Homo sapiens cannot be excluded.”

But soon enough, scientist skeptics weighed in. The temperature drop would not be as precipitous as Dr. Sagan and Company had forecast, they said. Nor would the quantities of combustible material — plastics, wood, petroleum, vegetation — be as vast as first thought. For some scientists, “nuclear winter” was a good deal less probable than a milder “nuclear autumn.” The end was not nigh. By 1990, even those who had issued the earlier doomsday warnings took a step back.

One of them was Richard P. Turco, a physicist who had coined the phrase “nuclear winter.” Not that menace no longer loomed, he asserted. “Essentially, what we say is that the basic physics we proposed turned out to be correct, although the magnitude of the effects has been moderated somewhat,” Dr. Turco said in 1990.

Actually, he said, he never believed humankind was likely to be wiped out. “That was a speculation of others, including Carl Sagan,” he said. “My personal opinion is that the human race wouldn’t become extinct, but civilization as we know it certainly would.”

Some might see an element of the surreal in a debate about whether the long-range effects of a full-scale nuclear war would be (a) indescribably horrible or (b) cosmically ruinous. That said, the specter of nuclear winter helped spur major reductions in the superpowers’ nuclear arsenals, by making the utter folly of nuclear warfare plainer than ever. Any country that dared to launch an attack would inevitably wind up under the same toxic gauze as everyone else, and thus commit national suicide.

The worldwide inventory of nuclear weapons is now believed to be about one-fourth what it was in the early 1980s. Last year, the total stood at an estimated 15,850, with more than 90 percent of them in the hands of the United States and Russia, according to the Stockholm International Peace Research Institute, which tracks the armaments.

But there are also now more nuclear-armed countries than in the 1980s — nine of them, by the institute’s count: the United States, Russia, Britain, France, China, India, Pakistan, Israel and North Korea. Not all are paragons of rational behavior. And not every scientist is convinced that the world is out of danger.

It would not take an American-Russian conflagration to inflict enormous environmental damage, said Alan Robock, a climatologist at Rutgers University.

“A ‘small’ nuclear war between India and Pakistan, with each using 50 Hiroshima-size bombs (far less than 1 percent of the current arsenal), if dropped on megacity targets in each country would produce climate change unprecedented in recorded human history,” Dr. Robock wrote in 2011 in the journal Nature. Temperatures, he continued, “would be lower than during the ‘Little Ice Age’ (1400-1850), during which famine killed millions.”

Back to geoengineering. Pumping chemicals into the upper atmosphere would amount to a mild — one can only hope extremely mild — version of a nuclear winter effect. Ideas along this line have been around for a while, but putting them into practice has proved elusive. For starters, who gets to choose what method, if any, should be employed? Do all countries have a say? How much would the project cost?

And how does anyone keep the immutable rule known as the Law of Unintended Consequences from kicking in? “Anything built by humans and operated by humans can fail,” Dr. Robock told Retro Report. “So would you trust our only planet to this?”

A concern often expressed about geoengineering is that it might undermine efforts to achieve the fundamental goal of keeping greenhouse gases out of the atmosphere. Would people change their carbon-spewing ways if they believed some quick fix existed?

Similarly, in the hypothesizing over the extent of climate change in the aftermath of a nuclear war, might not a more useful focus be how to keep the bombs from falling in the first place? Thoughts turn to “WarGames,” a 1983 film in which a supercomputer, thinking that it is merely caught up in an exercise, nearly touches off global nuclear warfare.

“A strange game,” the computer finally concludes, to everyone’s relief. “The only winning move is not to play.”

Huthi Press Claims That Patriot Volley Missed Their Riyadh Missile, Again

Follow Up December 20 Military spokesman Babak Taghpay announced that the Patriot missile defense system in Saudi Arabia failed to intercept the ballistic missile launched by the Yemeni missile force at Al Yamamah Palace in Riyadh on Tuesday (December 20th).

According to him, Saudi Arabia fired five MIM-104C missiles from the Patriot air defense system on the ballistic missile “Volcano-2H”, stressing that the missiles could not intercept the missile “Ansar Allah”, but the ballistic missile Did not reach the goal also according to his claim.

Earlier, Saudi media reported that Saudi Arabia had succeeded in repelling the rocket attack on Riyadh.

The New York Times has revealed earlier that the claims of Saudi Arabia and President Trump to repel a similar missile targeted King Khalid airport in Riyadh false and that the missile hit his target at the airport already.

Al-Masirah, close to Ansar Allah in Yemen, showed a video clip of what they said was the launch of a ballistic missile from Yemen at Al Yamamah Palace in the Saudi capital of Riyadh.

The “Yemeni War Media” account on Facebook also showed pictures of the “H2 volcano” missile, which was announced by the Saudi-led Arab coalition forces on Tuesday before heading to Al-Yamamah Palace in Riyadh.

The Yemeni missile force said on Tuesday that it had fired a rocket of the type “volcano 2H” towards a meeting of Saudi leaders at Al Yamamah Palace in the capital Riyadh, stressing that “the missile was issued from a base away from the target of a thousand kilometers, for a thousand days on the start of the Saudi aggression On Yemen. “

She added that “the Yemeni missile hit his target, which is a distance of a kilometer and a half from the US embassy in Riyadh, confirming that the embassy neighborhood 500 meters from the Royal Palace of Saudi Arabia.

For his part, military journalist Babak Taghpay said that the missiles of the Patriot missile defense system in Saudi Arabia, failed to intercept the ballistic missile, launched by “Ansar Allah” on Tuesday, 20 December.

According to him, Saudi Arabia fired five MIM-104C missiles from the Patriot air defense system on the ballistic missile “Volcano-2H”, stressing that the missiles could not intercept the missile “Ansar Allah”, but the ballistic missile He did not reach the goal either.
