Comments Off on Bering Sea ice is "at record low levels for this time of year"

Arctic sea ice is low, with the Bering Sea’s ice extent “the lowest recorded since at least 1979,” according to the National Snow and Ice Data Center (NSIDC). This reflects a larger overall trend: in April, Arctic sea ice covered an area 378,400 square miles below the 1981 to 2010 average. According to Alaska-based meteorologist Rick Thoman, Bering Sea ice extent “is five percent of normal” for the middle of May, and “there is almost nothing left except for near shore ice in protected areas.” The worrisome part of all this? There are still four months to go in the Arctic’s melt season. NSIDC provided information on Arctic sea ice extent in April of this year, and said 2016 and 2018 essentially tied “for lowest April sea ice extent on record.” Barents Sea and Bering Sea ice extent was below average, as it was during the 2017 to 2018 winter. According to Earther , the Bering Sea has been something of a ground zero for crazy ice, with sea ice disappearing when it was supposed to be growing in February, rebounding slightly in March, and then plummeting in April. Bering Sea ice extent is 5% of normal for mid-May and there is almost nothing left except for near shore ice in protected areas. Chukchi Sea ice extent also at record low, with open water now north of 71N. #akwx #Arctic @Climatologist49 @ZLabe @lisashefguy @amy_holman pic.twitter.com/Ur7UmoptgL — Rick Thoman (@AlaskaWx) May 17, 2018 Related: Extreme Arctic warmth deeply concerning, scientists say Warm oceans have played a role in the dive of Bering Sea ice levels; University of Alaska Fairbanks climate researcher Brian Brettschneider told Earther that “Bering Sea SSTs [sea surface temperatures] have been at record or near record levels for months now. This represents a strong positive feedback. Warm waters are hard to freeze, which then allows for more solar absorption.” And Bering Sea ice typically protects Chukchi Sea ice. When Bering Sea ice disappeared in February, open water seeped into the Chukchi Sea — an event that has probably only happened in one other winter on record. + National Snow and Ice Data Center Via Earther Images via Depositphotos and the National Snow and Ice Data Center

Crazy low Arctic sea ice levels will likely smash records this summer

Comments Off on Crazy low Arctic sea ice levels will likely smash records this summer

Arctic sea ice levels continue to plummet. Researchers from NASA and the National Snow and Ice Data Center tracking sea ice levels have found results that aren’t too surprising: Arctic sea ice extent is likely to break records for the lowest level this summer. Data from May revealed Arctic sea ice extent levels were ” two to four weeks ahead ” of the levels in 2012, the year that currently holds the dubious record. According to the National Snow and Ice Data Center , the “average ice loss” every day in May was around 23,600 square miles. That’s far faster than the 1981-2010 average, which was 18,000 square miles daily. Another factor to take into account is the type of ice . “Multiyear ice” is ice that doesn’t melt and helps keep Arctic ocean temperatures cool. If that ice melts – and it is right now – next winter there will only be “first-year ice” which then melts easier than multiyear ice. If there’s not as much multiyear ice, Arctic ocean temperatures will likely warm. According to Gizmodo, the Arctic is warming up at ” twice the rate ” as other areas on earth. Related: Arctic sea ice levels hit a new winter low – again Are there any weather patterns that can help explain these crazy low numbers? The National Snow and Ice Data Center noted that winds from Alaska and northern Europe bringing “pulses of warm air” led to “hot spots” across the Arctic. Central Siberia was the only area where temperatures were lower than the average recorded between 1981-2010. Then there’s the “early retreat” in the Beaufort Sea of ice – and as more ice melts, the Arctic warms . According to the National Snow and Ice Data Center, the numbers are “tentative” due to the “preliminary nature” of satellite data. However, they’re backed up by other sources, and it’s probable we’ll watch those numbers continue to plummet.

Arctic temperatures are literally off the charts

Comments Off on Arctic temperatures are literally off the charts

Even though things are just heating up in the Northern Hemisphere, many of us have already heard about the record-breaking hot temperatures in the Arctic . Now,  National Snow and Ice Data Center research scientist Andrew Slater has translated those temperature statistics into visual form with four telling graphs . Based on these diagrams, one meteorologist tweeted that Arctic conditions are as ” literally off the charts .” To create the charts, Slater pulled in data from the National Oceanic and Atmospheric Administration (NOAA), the Climate Forecast System Reanalysis (CFSR), and the Climate Forecast System Version 2 (CFSv2). His graphs show the Arctic has not had as many days below the freezing point of 0 degrees Celsius as it typically does. In fact, since we began keeping track in 1980, this year marks the most days we’ve recorded above freezing temperatures in the Arctic. Related: Arctic sea ice levels hit a new winter low – again Days higher than freezing is not the only record shattered in the Arctic this year. Sea ice levels were the lowest since 1979 . Just this month NOAA announced at Alaska’s Barrow Observatory they’d recorded “the earliest snowmelt date in 73 years of record-keeping, beating the previous mark set in 2002 by a full 10 days.” According to NOAA, usually Barrow Observatory is “one of the last places in the United States to lose snow cover.” High temperatures, early snowmelts, and low sea ice levels create a dangerous combination for Arctic wildlife. According to NOAA , polar bears and walruses have to adjust to their changing environment. Adorable black guillemont birds may not be able to find as many fish, meaning not as many of their chicks will survive. NOAA reported between January and April of this year, temperatures reached “an incredible 11 degrees above normal.” Many predict the Arctic will continue to break temperature records in the summer. It’s a vicious cycle: melting ice means the Arctic takes in more heat and melts more rapidly. Via Gizmodo and NOAA Images via Wikimedia Commons and Andrew Slater, National Snow and Ice Data Center

Why these round houses survive hurricanes that destroy traditional homes

Comments Off on Why these round houses survive hurricanes that destroy traditional homes

June first marks the official start of the Atlantic hurricane season, and with predictions for bigger and deadlier storms this year due to the transition to La Niña , coupled with above-average sea surface temperatures in the Gulf of Mexico, meteorologists are urging inhabitants of hurricane-prone areas to take extra precautions. Thanks to climate change, this trend towards more violent and volatile weather is showing no signs of slowing down , but a North Carolina based company named Deltec Homes has decided to fight back with hurricane-resistant homes that are so storm-proof, they’ve survived the likes of both Sandy and Katrina. A Deltec home still stands after Hurricane Dennis blew through – the neighbor with a traditional home next door did not fare as well. Deltec Homes was started in 1968 in Asheville, NC as a builder of hurricane-resistant round homes in seaside resort communities, particularly in the Atlantic south, where hurricanes are an ever present threat to coastal homes. Although the company has recently expanded into rectilinear Net Zero Energy Homes with the launch of the new Renew Collection (we wrote about it here ), Deltec originally made a name for itself with iconic storm resistant round homes. Initially commissioned for seaside resort communities, these structures soon became sought after by homeowners across the country for their striking aesthetics and durability. Deltec’s hurricane resistant homes are so strong that in over 48 years and with over 5,000 homes built, they’ve never had a home lost due to hurricanes or high winds of any kind. And that is all the more impressive considering that Deltec homes have stood against some of the most detrimental storms in history including Hurricanes Hugo, Sandy, Katrina, Ivan, Andrew and Charley. RELATED: Deltec launches line of super efficient, net-zero energy homes So what makes Deltec Homes different from other homes? The earliest forms of human shelter were round – inspired by Mother Nature’s most structurally stable ovoid designs such as the egg. Unlike traditional box-shaped homes, round homes possess only octagonally slight corners and sides. In the absence of sharp corners, wind and waves are permitted to flow freely around the house rather than allowing the kinds of pressure buildups that typically lead to structural failures. Circular homes are held together by a greater number of interconnected points, making their joints both more flexible and stronger than rectilinear constructions. For these same reasons (slight corners, smoother flow of wind), round roofs are far more successful at withstanding wind and are less susceptible to being lifted off in a storm. Radial floor and roof trusses, which meet in a center ring like spokes on a wheel, lock the building in a constant state of compression, which further reinforces the building’s strength. RELATED: Why Our Ancestors Built Round Houses – and Why it Still Makes Sense to Build Round Structures Today https://www.youtube.com/watch?v=ljN294eypZY&feature=youtu.be In addition to the impressive physics supporting these round homes, Deltec’s trusses and walls are composed of framing lumber that is twice as strong as traditional framing, while their reinforced windows and factory-precise prefab panels work to keep wind and water out. With an emphasis on environmental responsibility , these energy-efficient homes have the option to be topped with a reflective roof that minimizes radiant heat gain. An airtight envelope along with smart window placement and passive solar design, helps maintain the home’s balanced internal temperature. Deltec’s wide variety of add-ons and configurations allow buyers to incorporate solar power, triple paned glass, and more to make the home net-zero energy. The company recently achieved B Corp certification for meeting the highest level of verified social and environmental performance. With stormy weather on the horizon and speculation that hurricanes will increasingly begin to affect cities that least expect it, prospective homeowners might find it helpful to consider all their options before settling on a traditionally shaped house. These prefab round houses ship anywhere in the world, and according to Deltec’s Rachel Kassinger, “Since Deltec started in 1968 we’ve never lost a home due to hurricanes or high winds of any kind. The most damage ever reported were a few lost shingles off of a roof. It’s an extraordinary record considering our homeowners have had direct hits from some of the most damaging storms including Sandy, Katrina, Hugo, and Charley.” + Deltec Homes + Classic Deltec Homes All images © Deltec and Cayman Villas .

Comments Off on “Soul-Crushing” Cold Temperatures Sink to Record Low in East Antarctica

A new look at NASA satellite data has revealed that the Earth set a new record low for temperature in East Antarctica. In August 2010, the mercury hit -135.8°F, a soul-crushingly low temperature that will freeze even the strongest lungs. The old record was set in 1983, when temperatures were measured at -128.6 degrees by thermometers in Vostok, Antarctica. The change appears to be a permanent one, as temperatures came close to the record again this year, reaching -135.3 degrees on July 31.

Comments Off on US National Snow and Ice Data Center Reports Arctic Sea Ice Falls to New Record Low

Back in August, the US National Snow and Ice Data Center (NSIDC) ) reported that over 900 cubic kilometers of summer sea ice had disappeared from the Arctic ocean over the past year. At the time, that was a loss 50% greater than figures predicted by most polar scientists . However, now the NSIDC is reporting that the Arctic sea ice has reached its minimum extent for the year, equal to 1.32 million square miles. This is the lowest seasonal minimum extent noted in the satellite record since 1979.
