Proposing 2 'utopian' initiatives to 'save' the polar ice sheet, at first glance everyone thought it was a fantasy

Climate change is threatening the permafrost at the global poles, and if the situation does not change, melting ice and rising sea levels will seriously threaten life on the planet.

The Arctic is warming 4 times faster than the rest of the world, even up to 7 times in some regions. This information is given by a group of Norwegian researchers on the journal Nature.

One of the biggest reasons for this ominous result is the melting of sea ice in the Arctic, as the water surface absorbs solar radiation more readily than the white ice. While more ice melts, warming is increasing. According to one study, the Arctic sea surface temperature increased significantly while the ice surface temperature did not affect too much. This loop is known as the "tipping point in the climate system".

The Arctic is warming four times faster than the rest of the world.

Changes in the Arctic can have a ripple effect on the entire planet. For example, the melting ice in Greenland is capable of raising sea levels, submerging many lands; or, ocean current disturbances also have an impact on global weather patterns.

Given that situation, the question is, is there any way for us to prevent global warming, especially in the Arctic? Scientists have come up with two innovations, but they have not been proven to work in practice and at first glance everyone thinks it's crazy.

Exhaust gas into the stratosphere

According to Inverse, the first idea was to release gases like SO2 into the atmosphere. SO2 is an inorganic, colorless and toxic compound. They propose to discharge that material into the stratosphere, creating microparticles that reflect less sunlight into space.

As solar radiation reaching the ground decreases, the Earth's surface can cool. This process is called "stratospheric aerosol injection".

As solar radiation reaching the ground decreases, the Earth's surface can cool.

This concept has been studied for a long time and is similar when a volcano erupts. For example, in 1991, the eruption of Mount Pinatubo in the Philippines released 20 million tons of SO2 and ash into the atmosphere, reducing global warming by 0.5 degrees Celsius in a year - temporarily erasing up to 50% of the warming. globally since pre-industrial times.

Cooling the Earth in this way requires "pumping" SO2 into the stratosphere at low latitudes. That amount of material is then distributed globally by the wind and to the polar regions of the hemisphere it is discharged into, creating a reflective "shield". If the process were carried out in both hemispheres, it would cool the entire planet.

However, since the stratosphere at the equator is much higher (17km above the ground) than in the poles (about 9km), it is more feasible to just "discharge" gas in the subpolar regions.

"Lighten" the clouds

The second idea is to "lighten" the clouds covering the ocean for the same purpose, reflecting less solar radiation into space. This idea comes from the observation that under certain conditions, particles released from the chimneys of ships can create clouds over the ocean.

It is possible to "bleach" clouds by creating more aerosols from seawater.

The bottom line is, the type of cloud that forms over the ocean depends on the size of the salt crystals. If the crystals are small enough, then clouds are formed from lots of tiny droplets. This is important because clouds consisting of small droplets appear whiter than those with larger droplets and thus reflect more sunlight, even when the clouds have the same total amount of water.

Therefore, it is possible to "bleach" the clouds by creating more aerosols from seawater. This can be achieved near the North Pole through the deployment of boats with pumps and nozzles.

Here are two ideas that could help conserve the Arctic ice and give us time while we try to tackle the real root of the problem - the greenhouse effect caused by CO2 and the emissions of fossil fuels. People.

However, both of these Arctic warming ideas require more focused research and development, which may require global collaborative efforts.
