Swallowed by Nature

A friend sent me the above image this morning which recently appeared on the social media website, 9Gag. The photograph sparked a bit of a debate in the comments section of the site about where this image was actually taken. The source has not been identified and abandoned sites such as Chernobyl, Pripyat and Hashima Island were some of the guesses flying around. A few Google searches later and I found the full collection of otherwordly photographs in a Flickr account that were taken on May 4, 2011. The shots were taken within Keelung City, Taiwan (exact location between Ln. 290 and 230, Diaohe St., Zhongzheng Dist., Keelung City).

“It’s an uncompleted community and I really don’t know why it’s been abandoned,” says the photographer, Flickr user ‘cock_a_doodle_do‘.
The place does not have any specific name and other than these photographs, unfortunately there is very little (more accurately, nothing) on the internet about this mysterious and forgotten place that nature has reclaimed

Nonetheless, leave your imagination to run wild in this place as nature has been doing for quite a few years it would seem….

The most beautiful idea for an art installation that I have ever seen. 

The Mobile Garden’s portion of Art on Track in Chicago invited passengers to walk and sit on a thick carpet of green grass. Potted local plants rested on seats, on window sills, and on the floor, adding splashes of pinks, purples and reds with their small blossoms. Hanging plants dangled strands of leaves, flowers and berries all along the ceiling. Ivy-like plants also snaked around the poles and rails. Indigenous plants and sod were donated to The Mobile Garden, which is a project run by non-profit, noisivelvet. Plants and materials were generously donated to outfit the project by local sod farms, green roof gardens, and arboretums. Members of the Chicago art community rode the train to discuss the exhibition with passengers.

Noisivelvet’s initial proposal for Chicago’s Transit System was an open-air flat bed garden, which would be pulled behind the L line for one month. They hope that the positive feedback on this past weekend’s Mobile Garden will help make this a reality. (via)

Tiny aerosol particles, big global impacts

As interest in Earth’s changing climate heats up, a tiny dark particle is stepping into the limelight: black carbon. Commonly known as soot, black carbon enters the air when fossil fuels and biofuels, such as coal, wood, and diesel are burned.

Laura Nielsen for Frontier Scientists Tiny particles suspended in the air, present in the air we breathe and in the highest reaches of the atmosphere, are called aerosols. And those aerosols, though relatively short-lived, have a huge impact on global climate change. In fact, much of the atmospheric warming observed since 1976 in the Arctic, and elsewhere, can be attributed to aerosols. 

Minuscule dark sooty aerosol particles called black carbon absorb solar radiation. While carbon dioxide lingers in the air for roughly 100 years, airborne particles like black carbon may have a lifespan of only days or weeks before they drift back to ground or are carried down by precipitation. Still, their impact is evident. According to black carbon specialist Tami Bond of the University of Illinois, in one-to-two weeks, one pound of black carbon absorbs 650 times as much energy as one pound of carbon dioxide gas will absorb over the span of 100 years. That makes black carbon a short-lived climate forcer.

While black carbon is often human-created, the majority of aerosols which enter the atmosphere have natural causes. Wildfires create smoke, while volcanic eruptions spew forth gasses and sulfate particles. Drought promotes dust clouds, and desert sandstorms fling sand and mineral dust into the atmosphere. Even the ocean is a source of aerosols, since spray from waves sends salt particles into the air. Yet it’s beneficial to focus on the anthropogenic (human-caused) aerosols injected into the atmosphere, because they are not part of natural cycles. If we can understand our role in creating them and how they impact our planet’s climate, then we can change our behavior to better our environment.

Fossil fuel combustion is one anthropogenic creator of polluting particulate matter. Biomass burning to clear land or dispose of agricultural waste is another. Dust is sent aloft by overgrazing, deforestation, and excessive irrigation. Smog and other air pollution hazes the air over major cities. All of these aerosols travel swiftly through the atmosphere, and can influence places far from where they were released.

While carbon dioxide is the largest man-made contributor to global warming, the second largest contributor is black carbon. Black carbon is essentially minuscule soot, tiny dark particles suspended aloft in the atmosphere. It is created by engines burning fossil fuels like diesel, stoves burning biofuels like wood or dung, power plants burning coal, and certain industrial processes. This tiny demon has a a strong warming influence on the atmosphere. It also promotes and worsens human respiratory and cardiovascular diseases.

The impact of sunlight-absorbing black carbon on climate is complex. Functionally, the tiny dark particles absorb solar radiation and hold heat near the Earth. An old diesel truck traveling 60 miles would emit about one ounce of black carbon. One ounce absorbs as much sunlight as does an entire dark tennis court, says Bond. When black carbon falls on snow or ice it reduces the ice’s albedo, or reflectiveness. Instead of bouncing the sun’s rays back into space the darker ice absorbs solar radiation, heats, and melts. Enough black carbon deposited on a glacier’s surface speeds glacial melting. Yet the aerosol particles can also promote cloud formation or change cloud reflectivity. Clouds are amazingly versatile and have either a cooling or warming effect. To add to the complexity, sources which emit black carbon often emit other particles; sometimes those co-emitted polluting particles have a cooling effect.

Take a look at other polluting aerosols. Fossil fuel combustion (burning coal and oil) produces sulfates. Those sulfates scatter solar rays, and thus have a cooling effect. Yet in North America and Europe we have successfully cut down on the amount of anthropogenic sulfates in the air by heightening emission standards. Fewer sulfates means a lessened cooling effect, and so the impact of solar-ray absorbing black carbon is felt more strongly. Methane matters too. Methane is a greenhouse gas more potent than carbon dioxide. It’s a major component of natural gas, and humans boost its release through mining activities, creating decomposing garbage, and manure. It also escapes when ancient matter decays below frozen lakes or in thawing permafrost, and it’s escaping into the atmosphere in increasing amounts as temperatures in the Arctic warm. When it reaches the tropics, where ozone sits near ground level, atmospheric methane is an important precursor to ground-level ozone. Ozone itself is a greenhouse gas, but it also creates smog, threatens human health, and damages crops.

Polluting aerosols promote temperature increases. *”Aerosols, particularly black carbon, can alter reflectivity by depositing a layer of dark residue on ice and other bright surfaces. In the Arctic especially, aerosols from wildfires and industrial pollution are likely hastening the melting of ice.” In the Arctic, we see their effects in the diminishing summer ice cover, which creates a positive feedback loop of warming Arctic temperatures and can be linked to more severe weather events in much of the Northern Hemisphere.

Climate scientist Drew Shindell of NASA’s Goddard Institute for Space Studies suggests implementing 14 techniques to reduce the emission of black carbon and methane. Shindell states: **”We’ve shown that implementing specific practical emissions reductions chosen to maximize climate benefits would also have important ‘win-win’ benefits for human health and agriculture.” His study, which utilizes models run on supercomputers, indicates that implementing those 14 attainable emission control strategies could slow average global warming 0.9 ºF by 2050, increase global agricultural yields, and save hundreds of thousands of lives every year. Continuing to add black carbon and methane to the atmosphere will exacerbate climate change, while enacting the proposed control strategies could half the temperature increase we face in the next 40 years.

We already know how to reduce harmful man-made emissions. Controlling diesel emissions with particle filters, using cleaner-burning stoves and boilers, reducing or banning the burning of agricultural waste, and upgrading industrial brick kilns and coke ovens will all cut down amounts of black carbon in the atmosphere. Meanwhile, methane emissions can be reduced if leaks are fixed along long-distance pipelines, and wastewater treatment plants are updated. Methane from coal mines, oil works, and natural gas facilities can be captured, as well as that escaping from city landfills and farm manure. Steps like these, attainable and realistic, reduce climate impact by anthropogenic emissions, improve human health and living conditions, and boost crop yields.

Those steps alone will not be enough to stem the forward march of human-caused global climate change. We still need to take action to reduce carbon dioxide emissions. Carbon dioxide lingers in the atmosphere for a century, driving temperatures up. On the other hand, pollutants like black carbon and ozone-creating methane inflict powerful changes swiftly, then circulate out of the atmosphere in a matter of weeks. Taking steps to control these pollutants now can measurably slow global warming in the short term. According to Shindell, ***”We will have very little leverage over climate in the next couple of decades if we’re just looking at carbon dioxide. If we want to try to stop the Arctic summer sea ice from melting completely over the next few decades, we’re much better off looking at aerosols and ozone.” And we can do it now. Right now. Shindell says: ****”I found it remarkable that for incomplete combustion, which gives you black carbon, a group of just nine measures was able to pull down the emissions by about 70 to 80 percent. And all of the technologies already exist. There’s no technological barrier whatsoever to reducing black carbon.”

Antarctic ice melting at record rate, study shows

The evidence comes from a 364-metre ice core containing a record of freezing and melting over the previous millennium

Summer ice is melting at a faster rate in the Antarctic peninsula than at any time in the last 1,000 years, new research has shown.

The evidence comes from a 364-metre ice core containing a record of freezing and melting over the previous millennium.

Layers of ice in the core, drilled from James Ross Island near the northern tip of the peninsula, indicate periods when summer snow on the ice cap thawed and then refroze.

By measuring the thickness of these layers, scientists were able to match the history of melting with changes in temperature.

Lead researcher Dr Nerilie Abram, from the Australian National University and British Antarctic Survey (BAS), said: “We found that the coolest conditions on the Antarctic peninsula and the lowest amount of summer melt occurred around 600 years ago.

“At that time temperatures were around 1.6C lower than those recorded in the late 20th century and the amount of annual snowfall that melted and refroze was about 0.5%.

“Today, we see almost 10 times as much (5%) of the annual snowfall melting each year.

“Summer melting at the ice core site today is now at a level that is higher than at any other time over the last 1,000 years. And while temperatures at this site increased gradually in phases over many hundreds of years, most of the intensification of melting has happened since the mid-20th century.”

Levels of ice melt on the Antarctic peninsula were especially sensitive to rising temperature during the last century, he said.

“What that means is that the Antarctic peninsula has warmed to a level where even small increases in temperature can now lead to a big increase in summer melt,” Abram added.

Dr Robert Mulvaney, from the British Antarctic Survey, who led the ice core drilling expedition in 2008 and co-authored a paper on the findings published on Sunday in the journal Nature Geoscience.

He said: “Having a record of previous melt intensity for the Peninsula is particularly important because of the glacier retreat and ice shelf loss we are now seeing in the area.

“Summer ice melt is a key process that is thought to have weakened ice shelves along the Antarctic peninsula leading to a succession of dramatic collapses, as well as speeding up glacier ice loss across the region over the last 50 years.”

The ice core record suggested a link between accelerated melting and man-made global warming. But a different and more complex picture has emerged from another region of Antarctica.

A separate US study, published in the same journal, shows that thinning ice from the West Antarctic Ice Sheet Divide cannot confidently be blamed on greenhouse gas emissions.

An ice core record from this site indicates a strong influence from unusual conditions in the tropical Pacific during the 1990s.

In that decade, an El Niño event – a cyclical system of winds and ocean currents that can affect the world’s weather – caused rapid thinning of glaciers in the west Antarctic.

The spike in temperature was little different from others that occurred in the 1830s and 1940s, which also saw prominent El Niño events.

“If we could look back at this region of Antarctica in the 1940s and 1830s we would find that the regional climate would look a lot like it does today, and I think we also would find the glaciers retreating much as they are today,” said lead author Prof Eric Steig, from the University of Washington.

He said the same was not true for the Antarctic peninsula, the part of the continent closer to South America. Here, more dramatic changes were “almost certainly” a result of human-induced global warming.
