Scientists claim, this method will stop sea level rising

Hitekno.com – Rising of the surface sea ​​water to be one impact climate change global problem that must be faced by humans. Para scientist also looking for ways to be able to overcome it.

One of the ways scientists claim it can inhibit sea level rise dramatically is by “hacking into the glester.”

By “hacking” glaciers to reduce the amount of water they pump into our oceans.

In a new study, an international team of scientists led by University College London outlines nine techniques that can be used to slow glacial melting in the ice sheet. Greenland and Antartika.

The scheme will use “geo engineering”, a large-scale controversial technology that artificially changes Earth’s climate.

One approach put forward by the team is to brighten the surface of the ice, reducing surface melting.

Another way is to pump liquid carbon dioxide into the rocky bottom of the glacier.

Taken together to reduce carbon emissions, interventions can help prevent catastrophic climate change, according to the study’s lead author Andrew Lockley.

“Sea level rise is perhaps the most detrimental threat from climate change, “he said as reported by The Sun website, Sunday (28/3/2021).

According to him, this could cause many major cities in the world as well as other damage such as storm floods and loss of agricultural land.

“We wanted to find a way to control the process, “he said.

Average global temperatures are already 1.2C above pre-industrial levels and are expected to cross the 2C benchmark between 2050 and 2100.

The temperatures are soaring, causing the ice sheets that cover Antarctica and Greenland to shed trillions of tons of water into our oceans each year, causing sea level rise across the planet.

Research published last month showed that, at current speeds, average global sea level could rise by as much as 1.35m (4.1 feet) by 2100.

Scientists predict that a rise above one meter will be bad news for coastal cities, such as New York and Shanghai.

About 770 million people, 10 percent of the world’s population, live less than five meters (16 feet) above sea level.

“Most of the expected sea level rise comes from melting glaciers, “Lockley explained.

Almost all of them are in the large ice sheets of Greenland and Antarctica.

“This ice can melt due to global warming. But warming can also cause glaciers to slide faster.”

Some glaciers attached to rocks below sea level can break up very quickly once warmer seawater gets below them.

If the tip breaks or melts, the entire glacier can then slide even faster, accelerating the rate at which it is melting.

It is this process that Andrew and his team intend to discuss in their paper, which is published in the journal Advances in Climate Change Research.

One of the nine solutions suggested by the team involves using a giant drill to penetrate the rocky bottom of a glacier.

Water can then be pumped from the drilling site to slow down the ice giant.

“The water trapped under the glacier acts like an air spray that helps the air hockey pieces glide easily, “Lockley explained.

He explained that if you drill through the ice to let the high pressure water escape, this will cause the glaciers to stick together again.

“An alternative idea is to pump coolant to the bottom of the glacier. This will freeze the water, not throw it away, “he explained.

Another technique outlined in the paper would involve dusting glaciers with artificial snow or sand.

Lockley likens this to wearing a white shirt instead of black to stay cool on a warm day, because it is better at reflecting sunlight.

“When fresh new snow gets warm or dirty, it will absorb more sunlight. This means that lightening the surface of the snow can help stop melting, “he said.

He added that controls air pollution.

“We can make snow with a snow machine or a cloud-sowing plane. Dusting the ice with very shiny artificial sand can also work.”

The third tactic proposed by the team would involve thickening the ice sheet, which acts as a barrier for glaciers from flowing into the ocean.

Hopefully, say the researchers, this can hold the glacier longer.

The researchers admit that many of their ideas can prove to be very expensive and may not even work.

Geoengineering can also damage the environment, so more research is needed to assess the potential risks involved.

Breaking up floating ice to build concrete barriers, for example, can lead to the destruction of glaciers.

Scientists have raised concerns that the long-term effects of geoengineering are poorly understood.

Some say the controversial area equals “playing God” with the climate.

It also risks making people misunderstand that we no longer need to drastically limit greenhouse gas emissions.

However, Lockley believes that both of them can effectively manage our rapidly changing environment.

“We really need both. Nobody working in geoengineering research thinks we can ignore the need to dramatically reduce the use of fossil fuels., “he concluded.

That’s a new way scientists claim can reduce the problem of rising sea levels due to global climate change. (Suara.com/ Dythia Novianty).
