The Ice is in the Red Sea Reserve again, and no one is there; understand why


What's happening to Arctic sea ice is very simple: the land is grow warmer, and everything is melted. But on the other side of the planet, things are more complex, as can be seen from the ultimate Antarctic ice reduction experienced by scientists; screw their heads.

Antarctica was made in the new year with the recording of sewage ice levels, according to an update published by Thursday from the National National Center for Snow and Ice (NSDIC). On January 1, seagrass was covered by 2.11 million square miles of water; South Ocean arrives to the mainland, which is 726,000 square miles below the long-term average for its & that date. This starting point in 2019 continued to record the earliest intake of the earliest sea seas in December, causing the Antarctica to engage in scheduled levels set up just two years back, in the current summer of 2016-2017.

"In particular, it was thought that the period between November and December 2016 was a great visit to Antarctic marine ice at the time", wrote the NSDIC.

Perhaps you're thinking: Duh, this is a climate change. And that could be part of it! But an analysis carried out after the 2016-2017 sea-ice accident – which ended at least in a seasonal maritime test in March 2017 – decided to have a weather of bad weather a & # 39; corresponds to a very negative degree of the South Way Mode, where the winds are westward, the mainland was to go north, and # 39; blame.

In a short time, scientists discovered the last seabird on a natural variety. But it is not currently clear what is behind this year's ice disaster. In particular, the ice researcher at Washington, Washington, Ceartia Bitz gu Earther reported that the indirect method is not quite negative at present. We still do not care for the El Niño monster, as we were at the end of 2016.

"I think we need a bit back to a drag board," said Bitz to Earther.

Bitz was unhappy to think about whether the seagrass is back back as part of a new transition to climate change. Although parts of Antarctica feel that the heat has recently been Antarctic seagrass grow a bit, and reach a high tab in 2014. That's not a refusing the warmth movement, it addresses the complexity of sewage behavior in an environment affected by seasides and mainland.

Son Ngheim, senior research scientist at NASA Jet Propulsion Laboratory, The tells Earther that everything from Antarctic winds is dominated by a continental continent to a stream that is dominated by the ocean shape of the South Ocean; affecting Antarctic ocean ice. Bitz stated that ice would be melted on the edge of the continent as a factor, possibly paradoxical, could help with a new marine ice form by placing it; ban deeper deeper waters from rising to surface. Snowfall could also affect a variety of ice from year to year, according to NASA.

"It is not possible to consider another level of lower ice age in Antarctica now changing the weather," wrote Ngheim Earther in an email, indicating that the numbers of logs to & # 39; happening in the first part of the satellite record.

If there is nothing else, the emergency is sure to add extra research. The newly launched NASA, ICESat-2 administration satellite-end may have been able to give a loan, because it is possible to measure sea ice measure, a key indicator of ice age and health.

At the same time, the world's seabird cover continues to decline, with an early acidity in the Arctic; Find out what's happening around her & # 39; southern continent.
