Blowing a Few Tops

Ever stopped to consider the upside of volcanic eruptions? It’s not all death, destruction and hot liquid rock—scientists have a plan to cool the planet by simulating one such eruption.

Solar geoengineering involves simulating a volcano by spraying aerosols(气溶胶) into the atmosphere. When they combine with oxygen, droplets of sulfuric acid (硫酸) form. These droplets reflect sunlight away from Earth, cooling the planet. All good in theory, but the consequences are largely unknown and a few could be disastrous. In a study recently published in Nature Communications, researchers led by Anthony Jones, a climate scientist from the University of Exeter, found that using this technology in the Northern Hemisphere could reduce the number of tropical winds hitting the U.S. and Caribbean. But there's an annoying exchange: more winds in the Southern Hemisphere and a drought across the Sahel region of Africa. That’s because the entire climate system is linked—disrupting one region will invariably affect another. How would a nation react if another was causing its weather to get much worse? Would that be an act of war?

There is, however, a case for using solar geoengineering on a global scale. Jones says it could be used to “take the edge off” the temperature increases scientists are predicting. It could be used while the world searches for more effective strategies.

The study also highlights a far bigger problem with solar geoengineering: its complete lack of regulation. “There’s nothing that could stop one country just doing it,” Jones says. “You only need about 100 aircraft with three flights per day. It would cost $1 billion to $10 billion per year.” He adds, “It’s deeply disturbing that we have this technology that could have such a massive influence on the climate, yet there’s just no regulation to stop countries or even organizations from doing it.”

Jones cautions that there is much about the climate system we do not understand, as well as far more work that will need to be done before solar geoengineering is considered safe—or too dangerous to even discuss.

True intelligence

Taking charge of yourself involves putting to rest some very prevalent myths. At the top of the list is the notion that intelligence is measured by your ability to solve complex problems, to read, write and compute at certain levels, and to resolve abstract equations quickly. 1.It encourages a kind of intellectual prejudice that has brought with it some discouraging results. We have come to believe that someone who has more educational merit badges, who is very good at some form of school discipline is "intelligent". Yet mental hospitals are filled with patients who have all of the properly lettered certificates. A truer indicator of intelligence is an effective, happy life lived each day and each present moment of every day. 2.

Problem solving is a useful help to your happiness, but if you know that given your inability to resolve a particular concern you can still choose happiness for yourself, or at a minimum refuse to choose unhappiness, then you are intelligent. You are intelligent because you have the ultimate weapon against the big N. B.D. --Nervous Break Down.

"Intelligent" people do not have N. B. D. because they are in charge of themselves. 3.

You can begin to think of yourself as truly intelligent on the basis of how you choose to feel in the face of trying circumstances. The life struggles are pretty much the same for each of us. Everyone who is involved with other human beings in any social context has similar difficulties. Disagreements, conflicts and compromises are a part of what it means to be human. 4.But some people are able to make it, to avoid immobilizing depression and unhappiness despite such occurrences, while others collapse or have an N, B. D. Those who recognize problems as a human condition and don't measure happiness by an absence of problems are the most intelligent kind of humans we know; also, the most rare.

A. Holding a university degree indicates one’s ability to write properly worded documents.

B. If you are happy, if you live each moment for everything it’s worth, then you are an intelligent person.

C. N.B.D refers to an illness that causes a person to suffer from anxiety and to have difficulty living and working as usual.

D. Similarly, money, growing old, sickness, deaths, natural disasters and accidents are all events which present problems to virtually all human beings.

E. They know how to choose happiness over depression, because they know how to deal with the problems of their lives.

F. This vision of intelligence asserts formal education and bookish excellence as the true measures of self-fulfillment.
