Ten weird to save the earth come to an end global warming - the environmental protection industry

Ten weird to save the earth come to an end global warming - the environmental protection industry

1, Iron keep spreading to the sea green algae

British scientists recently declared that global warming caused ice to melt, but melting glaciers have led to an unexpected result, this result can even change the climate warming in the process. British scientists found that after the release of iron melting ice particles, leading to large sea of green algae to multiply by iron nourish the algae float to the ocean surface, by light Cooperation With a substantial absorption of atmospheric carbon dioxide.

To test this scientific discovery, a country's international team of scientists this month will be 800 miles southeast of the Malvinas Islands Marine Department to carry out a stunning scientific experiment, scientists from Cape Town, South Africa sailing departure, the number of tons of ferrous sulfate dust all the way "sow" to the Antarctic sea, which give green algae by large-scale artificial breeding. If this approach is successful, only 15 tankers of 10 years in the ocean turns to sow the iron particles, prosperity born of green algae can absorb all human emissions of carbon dioxide.

This method will cost 10 billion pounds, the feasibility of up to 8 / 10.

2, desert shield plastic film when the "Mirrors"

Many scientists believe that if the Earth's deserts into multi-faceted "great mirror", then the hot sun will be reflected back to space. Ordinary places on earth, average only 30% of sunlight is reflected back into space, but in snow-covered areas, the sun is reflected back into space has up to 90%, but the side effects that snow will melt faster.

The scientists suggested that human beings can be in sub-1.2 million square miles of land, took 10 years to a large area covered with reflective material?? Such as polyester film, it will be able to more sunlight reflected back into space, thus making the world cooler. There is also a similar idea is to establish a large area in the ocean covered with white film of the man-made island. But the plan has a major flaw: it is human to produce an unprecedented number of polyester film, and the production process itself will be a lot of carbon dioxide emissions to the Earth.

This method will cost 50 billion pounds, while the viability of only 1 / 10.

3, in space, support "umbrella"

We know that block sunlight to prevent global warming, so scientists are considering using the huge space of silicon mirror to block the sunlight to live.

The plan calls for the number 1 trillion of ultra-thin silicon mirrors launched into space, and use them to change the light line.

The University of Arizona astronomer Roger? Angel professor recommended that, when the silicon mirror after being sent to space, they can form into a 10 million square miles of space, "umbrella", which will be fired Earth's sunlight by 2%.

Angel has produced such ultra-thin silicon mirrors the model, each of a diameter of about 0.9 meters wide, mirror on the format of the diffraction pattern can change the direction of sunlight. Angel in a large shed for the experimental aircraft with a laser instead of the sun, instead of using a globe model of the Earth, when the laser fired at the Earth models stand in front of the mirror, the laser beam scattered into a small number of Road and not According to the model of the Earth again.

But the plan costly, in 50 years time, it cost 70 billion pounds annually, the viability of the scheme of 5 / 10.

4, to send the fleet overturned jet water for cloud

Scientists to create artificial weather has been a long dream, Edinburgh University scientist Stephen? Sauter said the salt spray through the clouds, can change the weather by artificial means.

Sauter and the United States National Center for Atmospheric Research in Colorado physicist John? Russum proposal, human beings can be sent to the Atlantic and Pacific wind ship unmanned vessels, these vessels can inhale sea water and sea water to the shape of spray mist into the air. This method can

thickening cloud density, which can be 4% more sunlight reflected back into space. Alleged human just sent 1500 to the ocean "for cloud ship" fleet, it could be produced more cloud cover, to prevent global warming.

Every ship to "create cloud ship" costs about one million pounds to 200 million pounds, but with the increase of human carbon dioxide emissions, "create cloud ship" fleet to 50 the number of annual increase. The feasibility of this method is 3 / 10.

5, "man-made volcano" create cloudy sky

"Man-made volcano" argument sounds a bit scary, but the Nobel laureate, the Dutch atmospheric chemist Paul? Crew Chen has suggested that humans can simulate volcanic eruptions, which can artificially create a block more sunlight Cloudy stratosphere.

Crewe Chen said, human beings can be shells filled with sulfur dioxide or large balloon fired about 16 kilometers above the earth's air, fabricate a similar formed after the volcanic eruption cloudy sky, thereby blocking more sunlight to Earth.

Cost of this program as much as 150 billion pounds, while the feasibility of only 2 / 10.
