Climate change is pushing Earth’s clouds higher and towards the poles

Comments Off on Climate change is pushing Earth’s clouds higher and towards the poles

A new study published in Nature warns that climate change is pushing Earth’s clouds higher and towards the poles. Why do these cloud patterns matter? For starters, there isn’t much solar radiation near the poles, so the clouds won’t reflect as much heat back into the atmosphere. Also, when cloud tops are higher they act similar to greenhouse gases, trapping radiation on Earth. These patterns only serve to bolster climate change . As scientists work to understand how climate change will affect our planet, one of the biggest uncertainties has been how warming will impact clouds . In the past, it was hard to obtain reliable observations; satellites gathering data typically weren’t designed to collect long-term records. Scientists at institutions in California and Colorado scrutinized ” corrected satellite records ” from as far back as the 1980’s. They found cloud patterns similar to those described by climate change simulations. These patterns predict that some clouds will move towards the poles, and some cloud tops will stretch higher into the sky. The scientists tried to account for natural variations by looking at models that incorporated elements like volcanic eruptions and increasing greenhouse gases, and models that didn’t incorporate those elements. Study lead author Joel Norris of the Scripps Institution of Oceanography said , “The pattern of cloud change we see is the pattern associated with global warming.” Related: World’s largest fog harvester produces water from thin air in the Moroccan desert The study doesn’t provide all the answers we need; it doesn’t look at low subtropic clouds, which some scientists speculate will be more important, and the cloud shift patterns could be due to erupting volcanoes in addition to greenhouse gas emissions. However, the study is another step on our path towards understanding how climate change will impact Earth. Max-Planck-Institute for Meteorology director Bjorn Stevens said, “This study reminds us how poorly prepared we are for detecting signals that might portend more extreme (both large and small) climate changes than are presently anticipated.” + Nature Via The Guardian Images via PublicDomainPictures.net and Wikimedia Commons

Comments Off on Worlds first Rose Museum in Beijing is wrapped in a beautiful perforated facade

? Set on a 100-hectare rose park that exhibited over 2,000 species of roses for the convention, the Beijing Rose Museum was designed to engage and overlook its stunning surrounding views. The museum is a modern take on the historical Chinese courtyard house that embraces and encloses open spaces, as a nod to traditional Chinese architecture. To showcase the history and culture of rose cultivation in China, which dates back to at least the 11th century B.C., NEXT architects wrapped the building in a 300-meter-wide, 17-meter-tall soft, stainless steel facade perforated with rose-shaped patterns. The detached facade creates a series of walled-off courtyards. Related: Bat bridge provides shelter for our winged friends in the Dutch town of Monster “The main challenge with the Rose Museum was to find a modern Chinese identity for a building which significance is so deeply rooted into Chinese culture,” said John van de Water, partner at NEXT Architects. The semi-transparent stainless steel walls blur the boundaries between the indoor and outdoor landscape. At night, the museum lights up from within for a beautiful glowing appearance that can be enjoyed from across a lake. + NEXT Architects Images via NEXT Architects , by Xiao Kaixiong

Comments Off on Erik Meldahl Wants to 3D-Print this Extraordinary Maasaica Car with Biodegradable Materials in Kenya

Imagine a third industrial revolution where sustainable energy and manufacturing set the standards for production of culturally-relevant cars? Maasaica is a concept from BMW that was built in the Serengeti using 3D printing technology , degradable materials and traditional handcraft. The intention with Maasaica was to create a concept that will evoke questions about how to best design a sustainable, locally produced car. Another aim was to question the methods and ideas of the conservative automotive industry. While Massaica doesn’t give all the answers, it is a step in the right direction. As designers we have a great opportunity to influence a product early in the process. However, one can also see it as we have a great responsibility to do our best to design products for a better society. That is what Massaica is about. My main inspiration came from the Maasai culture and new ways of manufacturing. The name Maasaica comes from the Latin word for the lion species in Kenya, Panthera Leo Masaica. + Maasaica Permalink | Add to del.icio.us | digg Post tags: 3d printed car , 3D-Printed Maasaica Car , biodegradable car , biodegradable materials , Erik Meldahl , green car Kenya , green transportation , locally sourced materials , Maasai people , Serengeti

Future Perfect: Harnessing geothermal energy from volcanoes

Comments Off on Future Perfect: Harnessing geothermal energy from volcanoes

Munmun Goswami: Geothermal energy from volcanoes Harnessing geothermal energy from volcanoes What’s happening right now? The world is witnessing growing tensions regarding acute fuel scenarios. The fossil fuel cry is increasing by ever growing decibels and causing the humanity at present to sway under the immense pressure of the question – how to end this cry and which is the best way to do so! In the run to find answers to these questions, we have tumbled upon solution in the form of renewable energy sources. The sun, the wind and the water are the most celebrated ones among them. Among the less adopted ones are sources like tidal, wave and geothermal energy. We dedicate this article to the last mentioned source of energy. For those who require a bit of explanation, geothermal energy is the energy of steam which is produced by heating water using the thermal energy of magma. It is a potent source of energy which is operational mostly in areas surrounding volcanic regions. The energy is mainly used to quench the energy hunger of populations residing around volcanoes and in quarries. At present, this source is being used to harness energy in places like New Zealand and Iceland. Trends 1. Indonesian geothermal Energy Project Indonesian geothermal energy project Archipelago’s 17,000 islands hold hundreds of volcanoes, and all that heat could be converted to renewable electricity. The Government of Indonesia has taken the volcanic energy source quite seriously. There has been a recent declaration from the side of the Government regarding a project that would aim at producing 4000MW of energy using this energy source. Making a good use of volcanoes would finally reduce the country’s huge dependence on carbon sources for energy. If this project turns successful, the Indonesian population would experience a drastic energy turnover, especially the 35 percent of the populace who are currently leading their lives in the electricity deficient darkness would have a reason to rejoice. This energy harnessed from volcanic heat would light up their homes perennially. 2. A derailed 2009n project by Wilfred Elders A derailed 2009 project by Wilfred Elders Harness energy from volcanic magma itself The university of California professor, Wilfred Elders recently published a paper, which says that it is now possible to harness magma itself as a source of energy, leave apart the water that is heated up by magma sources. The finding is sourced from the turn of events which the researchers underwent in the process of drilling for their geothermal test. It so happened that while the drills were boring deeper into the earth, super-heated magma unexpectedly made its appearance at a surprising depth even before the completion of the borehole drilling which was supposed to extend to 15,000 feet below the ground. The most amazing fact was that this magma was far hotter than other fluids boiling in the heart of the earth. Researchers feel that such sources of super-heated magma could itself be used to produce energy, if harnessed in the proper manner. 3. Geothermal Power project in Nicaragua Geothermal Power Project in Nicaragua Sitting on top of a chain of volcanoes, Nicaragua is the ideal candidate to exploit geothermal energy sources Nicaragua is fortunate to have a range of volcanic sources gurgling with energy, as also an active ecological participant like the inter-American Development bank, IDB. The bank has recently extended a generous loan of $30.3 for the development and operation of a plant that would make proper arrangements to harness energy out of this natural source in the best possible manner. The project has been named the San Jacinto-Tizate Geothermal Power Project. As of Nicaragua, the country is highly dependent on fossil fuel for fulfilling the energy requirements of its citizens. The success of this project would supposedly reduce this dependence and promise a greener future for the country. The project aims at increasing the capacity of an already existent 10MW arrangement to 72 MW. The concept As already discussed, this source of energy is derived from the underground magma cocktail. However, geothermal energy does not imply just magmatic heat. It also includes natural hot springs or water that is naturally heated up by the high temperatures beneath the earth. As of volcanic sources, the heat of the magma can be utilized fruitfully to heat up water and the steam thus obtained can be used to rotate turbines. The advantages What can be the most potent advantages of using natural and renewable energy sources other than reducing the pollution effect on the earth’s atmosphere? Another advantages of course is that if the present efforts become functional, geothermal energy would add to the already existing list of renewable sources of energy. The taxing on the fossil fuel sources would be reduced to some more extent. The impact It’s all positive. In fact, governments are inviting investments in this sector of energy development. If the volcano prone areas rise to this call, it is certain that much of the present energy cry would be solve without the need to turn to anything else. Volcanoes are a primitive and untamed source of energy in gushes. They can be the answers to the present questions if tapped and trained in the proper manner.
