Comments Off on The largest fire in Greenland’s history warns of an extreme future

The largest wildfire in Greenland ‘s history burned bright last summer, a potential warning sign for a future rattled by catastrophic climate change . Scientists are concerned that Greenland’s massive ice sheet may absorb the black carbon smog produced by the fires, as well as by any fires that occur in the future. One-third of the ice sheet has been affected by the soot from the wildfire, which accelerates heat absorption and glacial melting. “I think it’s a warning sign that something like this can happen on permafrost that was supposed to be melting at the end of the century,” rather than the present, Andreas Stohl, senior scientist at the Norwegian Institute for Air Research (NILU),  told Live Science . The fire burned about 90 miles northeast of Sisimiut, Greenland’s second largest city, and some suspect it was started by human activity. However, it is possible for  peat in oxygen-rich conditions to spontaneously combust, even when temperatures are low. In total, the wildfire burned about nine square miles of land. Of particular interest to scientists at NILU was the impact that soot might have as it landed on the ice sheets. “If you consider that Greenland has the largest ice sheet, apart from Antarctica , it immediately triggers some thinking,” NILU scientist Nikolaos Evangeliou told Live Science . Related: Scientists puzzle over subterranean heat melting Greenland’s glaciers Computer modeling enabled the NILU team to determine that seven tons of black carbon, approximately 30 percent of the total emissions produced by the fire , landed on the ice sheet . Ultimately, this amount of soot had a relatively small impact, less so even than that of North American wildfires that deposited soot across the sea to Greenland. Nonetheless, the fire may forecast larger ones in Greenland’s future. “If larger fires would burn, they would actually have a substantial impact on melting,” explained Stohl. Fires in Greenland potentially can also continue burning underground even when the surface fires have abated. “We cannot actually be sure that the fires (in Greenland) are out,” said Stohl.

Comments Off on Zaha Hadids only house rises like a spaceship in a forest near Moscow

Zaha Hadid’s only private house has just been completed and — to no surprise — it looks like a spaceship that has touched down on Earth. Created with a neo-futuristic aesthetic and ample glazing, the Capital Hill Residence stands in stark contrast with its leafy surroundings. The home is located at the heart of Russia’s Barvikha forest, just a couple miles west of Moscow . The $140 million project was completed for real estate developer and entrepreneur Vladislav Doronin, who runs Capital Group and OKO Group . The 36,000-square-foot sci-fi-esque house immediately draws the eye with its stalk-like tower that rises 117 feet above the ground. Hadid placed the master bedroom at the top, so Doronin could wake up to panoramic views of the tree canopy. The master bedroom connects to the lower levels with a glazed elevator and staircase. Related: New images capture Zaha Hadid’s luxury High Line condos in NYC The majority of the home is built into a slope and includes a pool, spa , gym and even a nightclub. Doronin, who met Hadid a decade ago, is reportedly very pleased with his home. “This striking and ambitious building is testimony to her genius,” he said, adding that he was sold from the moment he saw Hadid’s initial sketches on a napkin. “She created the perfect livable sculpture.” + Zaha Hadid Architects Via Dezeen Images via OKO Group

The melting Arctic is already changing the ocean’s circulation

Comments Off on The melting Arctic is already changing the ocean’s circulation

In the far North Atlantic , scientists have uncovered new evidence that an unusual infusion of freshwater into the ocean may already be affecting the ocean’s circulation. Mostly likely sourced from melting glaciers in Greenland or Arctic sea ice, the freshwater remains on the surface of the ocean for longer than denser saltwater. This could affect the ocean’s natural process known as convection, in which northbound surface water becomes denser and colder, thus sinking then traveling south at great depths. “Until now, models have predicted something for the future … but it was something that seemed very distant,” study lead author Marilena Oltmanns told the Washington Post . “But now we saw with these observations that there is actually freshwater and that it is already affecting convection, and it delays convection quite a lot in some years.” The research team gathered data on Irminger Sea to the southeast of Greenland , where they used ocean moorings to take measurements regarding the circulation of ocean water at key convection sites. While the study does not make any specific predictions regarding how convection may be affected, or how quickly it may change, the conclusion that freshwater from melting glaciers or sea ice may be already affecting convection is noteworthy. In 2010, 40 percent of melted freshwater remained on the surface through winter and into the next year. The staying power of the melted freshwater may suggest a positive feedback loop that could drive further mixing. Related: Pre-industrial carbon found in Canadian Arctic waters “It is possible that there is a threshold, that if there is a lot of freshwater that stays at the surface, and mixes with the new freshwater from the new summer, it suddenly doubles, or increases a lot, and the next winter , it’s a lot more difficult to break through,” said Oltmanns. It is already established that Atlantic circulation has been weaker than average since 2008, with scientists crediting climate change , cyclical patterns, or both. While the changes to convection may occur over time, the latest study indicates that change may occur more rapidly than expected. “There might be a threshold that is crossed, and it’s harder to get back to where we were before,” said Oltmanns. “It’s possible.” Via The Washington Post Images via Depositphotos (1)

New research reveals that sea levels could rise 1.5 inches every year

Comments Off on New research reveals that sea levels could rise 1.5 inches every year

You know how we’ve been freaking out about how quickly global warming is causing ice to melt and sea levels to rise? Turns out, we weren’t panicking nearly enough. New satellite data shows that sea levels will continue to rise at a pace that is much faster than anyone predicted – at least 1.5 inches PER YEAR. The Proceedings of the National Academy of Sciences analyzed 25 years of satellite data from across the planet to determine how far sea levels have risen, and how much more they may rise in the near future. According to their findings, in the past 25 years, sea levels have risen nearly 3 inches. At the current rate of acceleration, sea levels will be 2 feet higher by 2100. Related: New study shows a 1-in-20 chance climate change will cause a complete societal collapse The rise is being caused by warming oceans and melting glaciers and ice sheets. The recent acceleration, according to the study, is the result of melting ice sheets in Greenland and Antarctica. The predicted sea level rise of 2 feet by century’s end may not be catastrophic for wealthier countries, but it will be devastating for those without the money to deal with impacts of global warming .

New NASA tool shows which melting glaciers will affect coastal cities

Comments Off on New NASA tool shows which melting glaciers will affect coastal cities

NASA has developed a new tool  that individuals and communities can use to determine the precise impacts that sea level rise will have on individual coastal cities . This newly accessible information will enable scientists and policymakers to have a more complete understanding of the consequences of climate change in specific areas. “This study allows one person to understand which icy areas of the world will contribute most significantly to sea level change (rise or decrease) in their specific city,” said Eric Larour, one of the study’s authors, in an interview with CNN . While most coastal communities around the world understand the imminent risks to their survival from sea level rise , this tool allows them to plan more precisely for the future. Current projections estimate that coastal communities will face a sea level rise of one to four feet, depending on location. Since the impact of melting sea ice will be felt differently in different places, it is important for communities to have as precise and accurate information as possible. NASA’s new tool, developed at the Jet Propulsion Laboratory, incorporates the rotation of the Earth and gravitational variables to more precisely identify how specific bodies of melting ice will impact certain communities. Related: Boston outlines its plans to adapt to rising sea levels To create this tool, researchers conducted a study in which they analyzed data for 293 coastal cities to calculate local sea level rise and the glacial source of this newly liquid water. Glaciers farthest away from a particular city tended to be the most responsible for its sea level rise, due to gravity. “Ice sheets are so heavy, that when they melt, the gravity field is modified, and the ocean is less attracted to the ice mass,” said Larour in an interview with CNN . “This means that locally, close to the ice change itself, sea level will decrease.” Larour hopes that this new tool will empower local communities to make informed decisions as they prepare for unfolding impacts of climate change . + NASA Jet Propulsion Laboratory Via CNN Images via NASA and Depositphotos

Comments Off on INFOGRAPHIC: What you need to know about rising sea levels

We hear a lot about the rising sea levels, but besides the obvious, what does that really mean? Global warming, melting glaciers and thermal expansion is causing oceans to rise, and at this point, we aren’t going to be able to stop it. That means cities like Washington D.C., Miami and New York City are going to start seeing some terrible floods. Addressing the problem could cost billions of dollars. The following infographic is a quick and dirty guide to rising sea levels and what our future holds (it isn’t good). Read the rest of INFOGRAPHIC: What you need to know about rising sea levels

Comments Off on Artists Bigert & Bergström are rescuing Sweden’s highest peak from climate change

In the past few decades, the south peak of Kebnekaise, Sweden’s highest mountain (which mainly consists of a glacier), has been melting due to the warming climate. It’s getting so bad that the rocky north peak threatens to take over as the highest point in Sweden, enticing climbers to attack the more-dangerous route to reach Sweden’s highest peak. To help halt the melting, artists Bigert & Bergström have deployed a golden cloth to protect the south peak. Last summer, a 500 square meter reflective golden cloth was deployed on the mountain’s south peak and for several summers prior, similarly large areas of the glacier were covered in the reflective cloth, which has successfully saved 3 meters of glacial ice each summer. Known as the Rescue Blanket for Kebnekaise, the artists are now featuring an exhibition of the project called The Freeze. The project will be shown at Gallery Belenius Nordenhake , opening in Stockholm January 16, 2016. + Bigert & Bergström

Climate change is becoming more and more difficult to ignore and rising sea levels are just one of the visible consequences of these effects. NASA has predicted a one meter rise worldwide in the next few centuries just by gathering sensitive satellite data, yet other scientists are also considering how studying the Earth’s core and the rotational effects of changing sea levels may also serve as predictors. These data can help coastal areas prepare for the future. Read the rest of Scientists discover that the melting glaciers are slowing down the Earth’s rotation

NASA satellites are pretty nifty, in large part because they capture world events that we might not know about otherwise. That’s what happened recently, when NASA’s Landsat 8 recorded the image above on August 16 of Greenland’s Jakobshavn glacier, which is one of the world’s largest and fastest melting, which. When researchers compared recent images to images captured two weeks ago, they discovered that  the glacier just lost an enormous chunk of ice . So big, in fact, that it may be the largest chunk of ice loss ever recorded. Read the rest of NASA satellite shows this glacier just lost the biggest chunk of ice ever recorded
