Arctic sea ice at record low October levels: Danish institute – Hurriyet Daily News

Arctic sea ice at record low October levels: Danish institute

Sea ice in the Arctic was at record lows for October, as unusually warm waters slowed the recovery of the ice, Danish researchers said on Oct. 28.    

Diminishing sea ice comes as a reminder about how the Arctic is hit particularly hard by global warming.    

Since the 1990s, warming has been twice as fast in the Arctic, compared to the rest of the world, as a phenomena dubbed “Arctic amplification,” causes air, ice and water to interact in a reinforcing manner.    

“The October Arctic sea ice extent is going to be the lowest on record and the sea ice growth rate is slower than normal,” Rasmus Tonboe, a scientist at the Danish Meteorological Institute (DMI), told AFP, noting that the record was unequaled for at least 40 years.    

According to preliminary satellite data used by the institute, sea ice surface area was at 6.5 million square kilometers (2.5 million square miles) on 27 October.    

Every year, some of the ice formed in the Arctic waters melts in the summer.    

It usually reaches a low point of about five million square kilometers, but then re-forms to cover about 15 million square kilometers in winter. Warmer temperatures are now reducing both the summer and winter extent of the ice.    

Satellite data has been collected to monitor the ice precisely since 1979, and the trend towards a reduction is clear.

For the month of October, measurements show an 8.2 percent downward trend in ice over the last 10 years.

Already in September, researchers noted the second-lowest extent of sea ice recorded in the Arctic, though not quite hitting the low levels recorded in 2012.    

But warmer-than-normal seawater slowed the formation of new ice in October.        

Water temperatures in the eastern part of the Arctic, north of Siberia, were two to four degrees warmer than normal, and in Baffin Bay, it was one to two degrees warmer, DMI said in a statement.    

The institute said this was following a trend observed in recent years, which was described as a “vicious spiral.”

“It’s a trend we’ve been seeing the past years, with a longer open water season making the sun warm the sea for a longer time, resulting in shorter winters so the ice doesn’t grow as thick as it used to,” Tonboe said.    

Since the melting ice is already in the ocean it does not directly contribute to the rise in sea levels.    

But as the ice disappears sunlight “gets absorbed in the ocean, helping to further warm the Earth,” Claire Parkinson, a climate scientist at NASA, told AFP in September.    

Thus, with less ice reflecting sunlight, oceans are heated directly.    

Over the last 40 years, the Arctic has also become more of a strategic interest to world powers.    

Less ice in certain areas opened up new maritime routes, which are destined to play a larger role in international trade, meaning a larger financial stake for Arctic state actors.    

The region is also estimated to house 13 percent of the world’s oil reserves and 30 percent of undiscovered natural gas deposits.    

Germany’s Potsdam Institute for Climate Impact Research (PIK) said on Oct. 27 that under current levels of atmospheric CO2 – roughly 400 parts per million – the melting of Arctic sea ice would raise global temperatures by 0.2C.    

That’s on top of the 1.5C of warming our current emissions levels have rendered all but inevitable, and the safer cap on global warming aimed for in the Paris climate accord.

The province of Ontario announced Friday that Windsor Essex will be moving to Red, or “Control” status under the province’s COVID-19 response framework.

The changes will come into effect on Monday, November 30th 12:01am.

“The health and safety of all Ontarians is and will always be our top priority, that’s why we are following the advice of the Chief Medical Officer of Health and other health experts and making this adjustment today,” said Christine Elliott, Deputy Premier and Minister of Health. “Over the last week we have seen a shift in the trends of key public health indicators in regions across the province, and by moving [regions to new levels] in the framework, we can ensure that the necessary targeted measures are in place to stop the spread of the virus and allow us to keep our schools and businesses open.”

Earth is 2000 light years closer to supermassive black hole at the center of our galaxy than we thought – CTV News

Published

 on


A new map of the Milky Way by Japanese space experts has put Earth 2,000 light years closer to the supermassive black hole at the center of our galaxy.

This map has suggested that the center of the Milky Way, and the black hole which sits there, is located 25,800 light-years from Earth. This is closer than the official value of 27,700 light-years adopted by the International Astronomical Union in 1985, the National Observatory of Japan said.

What’s more, according to the map, our solar system is traveling at 227 kilometers per second as it orbits around the galactic center — this is faster than the official value of 220 kilometers per second, the release added.

These updated values are a result of more than 15 years of observations by the Japanese radio astronomy project VERA, according to an announcement released Thursday from the National Observatory of Japan. VERA is short for VLBI Exploration of Radio Astrometry and refers to the mission’s array of telescopes, which use Very Long Baseline Interferometry to explore the three-dimensional structure of the Milky Way.

Because the Earth is located inside the Milky Way, it’s difficult to step back and see what the galaxy looks like. To get around this, the project used astrometry, the accurate measurement of the position and motion of objects, to understand the overall structure of the Milky Way and Earth’s place in it.

The black hole is known as Sagittarius A* or Sgr A* and is 4.2 million times more massive than our sun. The supermassive hole and its enormous gravitational field governs the orbits of stars at the center of the Milky Way. Reinhard Genzel and Andrea Ghez earned the 2020 Nobel prize for physics for its discovery. There are several types of black holes, and scientists believe the supermassive ones may be connected to the formation of galaxies, as they often exist at the center of the massive star systems — but it’s still not clear exactly how, or which form first.

MORE PRECISE APPROACH

In August, VERA published its first catalog, containing data for 99 celestial objects. Based on this catalog and recent observations by other groups, astronomers constructed a position and velocity map. From this map, the scientists were able to calculate the center of the galaxy, the point that everything revolves around.

VERA combines data from four radio telescopes across Japan. The observatory said that, when combined, the telescopes were able to achieve a resolution that in theory would allow the astronomers to spot a United States penny placed on the surface of the Moon.

To be clear, the changes don’t mean Earth is plunging toward the black hole, the observatory said. Rather, the map more accurately identifies where the solar system has been all along.
