Rising Seas Threaten Low-Lying Coastlines | Ecology Global Network - 0 views

  • The inexorable rise of the waters of the earth’s oceans since 1880 has already contributed almost 20 cm (nearly a foot) since 1880, and more recently the rise continues at an accelerating pace . The IPCC (2007) predicts an increase of sea level of between 0.5 to 1.5 m by the year 2100
  • Island nations under threat include Bermuda and the Bahamas in the Atlantic, the Pacific Islands of Palmerston, Tuvalu, Kiribati, Vanuatu, Marshall Islands, Cook Islands, Fiji, Solomon Islands, and the Maldives in the Indian Ocean
  • in terms of numbers of persons impacted, the oceanic islands pale in comparison with the slow-motion disasters that will occur in densely populated, low-lying coastal cities like New Orleans, New York, Los Angeles, Tokyo, Amsterdam, Mumbai, Shanghai, Singapore, Jakarta and Dhaka.

  • The extraordinary warming of 2.5°C (4.5°F) over the past 50 years on the Antarctic Peninsula is both the world’s greatest temperature change and least opportune venue for warming on the planet. Warmer air and currents penetrating deep into West Antarctica could initiate collapse of the marine based West Antarctic Ice Sheet ice sheet (Joughin and Alley, 2011), rapidly elevating global seas by as much as 3-6 meters.

In Future, Let's Build Cities Around Water | Ecology Global Network - 0 views

  • Water-sensitive urban design is slowly seeping into our cities. The City of Mandurah in Western Australia, for example, has adopted a stormwater management plan
  • Experts predict that the world’s cities combined will gain almost one million extra people a week leading up to 2050.
  • The Cities of the Future program is about recognizing the issues that cities are facing, and looking for the new models that are doing a better job at building resilience

  • The most critical challenges for existing cities are the institutional arrangements, regulations and underlying culture of water management agencies

Europe's Cities Resilient to Climate Change | Ecology Global Network - 0 views

  • Many cities are now facing impacts such as water scarcity, flooding and heatwaves, which are expected to become more frequent and intense than they are used to. Cities need to start investing in adaptation measures using ideas and best practice from around the world.
  • Climate change adaptation should be flexible to accommodate uncertainty
  • Adaptation should work with nature, not against it.
  • ...2 more annotations...
  • Many adaptation measures can make cities more pleasant places to live. Malmö in Sweden manages rainwater flows with a new open storm-water-system. Here, green roofs and open water channels lead rainwater into collection points that form a temporary reservoir.
  • People also need to change behaviour in order to adapt.

Энтузиаст изготовил модель радиального двигателя из дерева и пластика - 0 views

  •  
    Если вы любите двигатели, но вам больше нравится работать с деревом - всё в ваших руках. Энтузиаст Иен Джиммерсон [Ian Jimmerson] решил совместить свои хобби, и изготовил модель радиального двигателя в натуральную величину. Почти все части двигателя выполнены из дерева, цилиндры же для наглядности сделаны из прозрачного пластика.

В ОАЭ планируют создать рукотворную гору для увеличения количества осадков / ... - 0 views

  • Поскольку цена на нефть сильно упала, и в скором времени вряд ли поднимется до прежних показателей, ОАЭ собирается снизить зависимость своей экономики от нефтяных доходов. В частности, планируется активно развивать туризм.
  • планируют улучшить климатические условия, чтобы превратить пустыню в цветущий сад.
  • А что для этого нужно сделать? Конечно, возвести гору.

  • только в 2015 году было осуществлено 186 операций по «посеву облаков». Эта миссия действительно была успешной — в марте этого года в ОАЭ выпало рекордное количество осадков, что даже привело к затоплению части площадей региона (временное наводнение).
  • Сравнивать можно только с китайской программой уничтожения гор для постройки городов, что привело к экологической катастрофе.

  • what if there was a kinder kind of high-rise?
  • PinkCloud.dk entered renderings that showed horizontal neighborhoods flipped on their sides
  • FLIP/CITY, green space would connect workplaces, shops, and residences for people of various incomes on a vertical scale.

  • . The architects argued that flipping a landscape vertically, so that public space connects homes, schools, and workplaces within one building, would create more mixed use communities than high-rises with hundreds of rooms simply stacked on top of one another.
  • developers are rarely enthused about building diverse communities--often, it's more profitable for them to build new, luxury towers that act like gated communities for the rich. A project like FLIP/CITY would likely require political will, too, and zoning laws would have to adapt to the new mixed-use shapes and needs created by them.

China's Great GREEN Wall to stop climate change - 1 views

  • Will China's Great GREEN Wall save the country from dust storms? 100 billion tree project could halt advancing Gobi Desert

  • China is planting huge strips of trees to stop the Gobi DesertFor decades the desert has been advancing and causing serious dust storms in key cities such as BeijingSince 1978 the government has been planting trees to reverse the widespread deforestation that took place in ChinaNow a recent study suggests the project has been a successThey found increased vegetation and lower levels of dust storm intensityBy 2050 100 billion trees will be planted across a tenth of the country

    Since 1978 China has been planting huge strips of trees to stop the Gobi Desert which is advancing to the key cities such as Beijing.The interim project results are positive. They will plant 100 billion trees across the country by 2050 to cover 1/10 of the country.

Discovery of plastic-eating bacteria could lead to new ways to recycle | The Verge - 1 views

  • A newly-discovered bacterium that feeds on plastic could help develop new recycling methods.
  • The discovery was made by researchers from Japan, who say that the microorganism is remarkable for its ability to breakdown completely a common type of plastic known as PET. This digestive process is slow, and the short-term implications of the discovery are uncertain, but studying the bacterium — which has been given the name Ideonella sakaiensis — could lead to new ways to safely get rid of junk material.
  • It's thought that plastic bottles take 450 years to break down, and although some plastics do degrade quicker in the ocean, this just leads to more chemical pollution.
