A friend of mine today firmly told me that there's no global warming and we should all stop trying to struggle improve efficiency (and then as an afterthought added "especially with policies, and liberalness and the such). It was a dumb inconsiderate reply but non the less, I snapped at him. I told him that we should just let ourselves cut down all the trees and pollute our atmosphere so much that marathon running would become a dangerous sport. He looked at me sheepishly and said something to the effect of well you shoulden't worry so much and Al Gore is a nutcase. Typical conservative catholic response. The point of telling you this story was to encourage you to say what you think in the comments section, and to inspire you to create ways to make us (the race of polluters) better. So go on, debate it up!

1) We are put carbon into the air by burning fossil fuels. What are fossil fuels? Plants that were buried eons ago. How can we reverse the trend? By burying plant matter, thus sequestering CO2 from the air. Fortunately, there is a convenient way to do so. Put lawn waste and paper in a landfill. Paper is mostly made from tree farm trees. They'll replant to grow more. New trees absorb CO2 from air. a) Bury paper. Don't recycle it. b) Bury lawn waste, don't mulch or compost. 2) Since people do burn stuff to keep warm, travel, and do stuff in general, is there a way to do this without as much effect on climate? Yes. Global COOLing happens when particulates (smoke) reflect some sunlight. So the laudable efforts to produce cleaner emissions from cars, powerplants, etc, also prevents the effect of global cooling. Ironic that a filthy smoke belching 1800s smokestack which lead to respiratory problems, etc, would also put out particulates that block some sunlight. a) make smoke, not clean exhaust. I welcome responses whether you agree or disagree. To be perfectly honest, I'm not sure if I agree myself ! Just putting it out there.

The growing number of jellyfish in the oceans has scientists worried, as they say it is an indication of how badly the ocean is being treated. They are showing up in places where they have never been seen before, and this is being attributed to a number of causes, including global warming and overfishing of the jellie's natural predators. LinkyI can personally attest to this one. I went to the beach and got stung by these little nasties. There must have been thousands and thousands of them swimming around. When they sting you, it HURTS. I had whip marks on my arms and legs for hours. Stupid jellyfish...

Who needs to worry about cutting back carbon emissions or sequestration when you can just launch a rocket into the atmosphere loaded with sulfur to simulate a volcanic eruption? Or what about making trees shinier? Then again you can always try to cover the glaciers.These are all ideas that have been put out there to save us from ourselves, but almost sound like we're trying to kill ourselves off even faster. Especially that sulfur rocket bit.Check out these five techniques on the green fringes. Where do you think any of this effort should be going? 5 Strange Stop-Gap "Solutions" to Climate Problems

OK well most of the question is in the title. But I have herd things like there wont be anymore snow in fifty years, the polar ice caps are being destroyed, the ozone is covered in holes and that ethanol is actually worse for the enviorment than gasoline because it produces more carbon emissions. And to go along with that question are we getting to smart ? A little to technologically advanced.

The Stay Warm Contest is requesting our warmest solutions to make it through the rather rough winter we've been having. In particular, they want to see our favorite low energy solutions. Therefore, may we post instructables about warming up the climate in an attempt to stay warm? Thanks, Purduecer p.s.

"Recently, Royal Dutch Shell PLC received $865 million from the Canadian government for a carbon capture and storage (CCS) project. Green roofs, rooftops with plants, can capture and store carbon, according to a new study by Michigan State University in East Lansing. The technology to build green roofs already exists, and they can be created for much cheaper than a CCS project."The key to fighting global warming is capturing carbon from the atmosphere and storing it in new reservoirs that weren't storing carbon before," lead researcher Kristin Getter said...."This looked like a rather elegant answer to the Green Question.

UK Broadcasting watchdog OfCom has ruled that the Channel 4 documentary The Great Global Warming Swindle broke broadcasting rules by implying that GW was not due to human activity.The film's key contentions were that the increase in atmospheric temperatures observed since the 1970s was not primarily caused by emissions of greenhouse gases from burning fossil fuels, and that the modern focus on climate change is based in politics rather than science. It is seen in some "climate sceptic" circles as a counter to Al Gore's movie An Inconvenient Truth, and credited with influencing public perception of climate science. It has reportedly been sold to 21 countries and distributed on DVD. GW experts featured in the documentary complained that they were quoted out of context, had not been told of the aims of the programme makers, and some quotes attributed to experts were, allegedly, made up by the reporters."It's very disappointing that Ofcom hasn't come up with a stronger statement about being misled," said Sir John Houghton, a former head of the UK Met Office and chair of the Intergovernmental Panel on Climate Change (IPCC) scientific assessment. "I know hundreds of people, literally hundreds, who were misled by it - they saw it, it was a well-produced programme and they imagined it had some truth behind it, so they were misled and it seems Ofcom didn't care about that," he told BBC News."The programme has been let off the hook on a highly questionable technicality," said Bob Ward, former head of media at the Royal Society, who played a prominent role in co-ordinating objections to the film. "The ruling noted that Channel 4 had admitted errors in the graphs and data used in the programme, yet decided that this did not cause harm or offence to the audience." Plaintiffs accused the programme of containing myriad factual inaccuracies, but Ofcom says it was "impractical and inappropriate for it to examine in detail all of the multifarious alleged examples... set out in the complaints." On another issue - whether contributors to the programme had been treated fairly - Ofcom mainly found against Channel 4 and the film's producer WagTV. Former UK chief scientific adviser Sir David King had been misquoted and had not been given a chance to put his case, the regulator said. Ofcom also found in favour of Carl Wunsch, an oceanographer interviewed for the programme, who said he had been invited to take part in a programme that would "discuss in a balanced way the complicated elements of understanding of climate change", but which turned out to be "an out-and-out propaganda piece, in which there is not even a gesture toward balance". The film alleged that the IPCC's scientific reports were driven by politics rather than science, and Ofcom ruled the organisation had not been given adequate time to respond.

Please follow me and imagine this. You're in a city and are taking a rattling train somewhere to the edge of town. The buildings get shorter as they get wider. You are entering the industrial area where the jobs dried up long ago. Where there are more broken windows than whole ones in each building. You pass the streets your parents warned you about and a street covered in "DO NOT CROSS" tape. Two stops later you get off at the stop your friends told you about questioning your sanity and wondering why your friends brought you out there. The graffiti is beautiful though, and somewhere in the distance you can hear the thump of heavy bass. The address your friend gave you can't be right, you look up and see a massive complex thankfully this one seemed to have more of it's windows intact. You push the rusting door noticing the rough texture and surprising heft. You walk in and see a roughly refinished hallway. The drywall isn't yet painted but it appears that this massive factory has been transformed on the inside. You pass a few drywalled off artists studios on the first floor and they smile at you with plaster in their hair. It smells like lavender and you notice you just passed an artist making candles. The "hackerspace" your friend told you about is on the second floor. So you walk to the cargo elevator and push the call button. It makes a horrifying rattling sound as it descends to meet you, instead of a door it has a grate. You take it up and as it slowly moves you can see concrete, then wood and suddenly the thumping bass get's louder - Hello Skrillex. It's too much to take in at first, you only notice the chaos. There are tools everywhere and in every state of operation. A wall of computer monitors lines the back wall. There's someone binding books in the corner, and what appears to be a viking with knitting needles sitting in what appears to be a lounge, he looks up and smiles at you and says "welcome to Scrumspace*!" you've arrived at your first hackerspace. Notice an open basket of dollar bills and place a 2 dollar donation in the basket near the fridge and grab yourself a drink from the fridge in the kitchen. You walk into a common area painted like a scene from Super Mario with what appear to be server racks painted as the tubes. Finally you see your friend. He walks in with a scorched shirt and you see his eyes twinkling through the welding goggles. "Told you this place is awesome!" he says. Hackerspace Values and Culture Hackerspaces like this exist almost all over the world. These places collect (and perhaps helps inspire) people who are passionate initiators. Walking into one you might find someone who wants to share a new iPad application which monitors the GPS on the weather balloon they've released -"It's over //CHINA// right now!!". People in hackerspaces are happy to share, it's a part of the culture! Interacting with them is often uplifting and inspiring. They are building and creating things they think is amazing. They may be playing with technology or science or art without concern for the categories. The only apparent question they ask themselves is how AWESOME is this!? It's a contagious atmosphere of capability where people learn from each other constantly. They can't help it! People are so passionate about what they are doing, they inadvertently teach. The other feature of a hackerspace which is more important is that they give people a venue. It's an open space that is owned by the members. Need a place to host a workshop on hat felting, it's yours! Need a place to build the first prototype of your product? Just make sure you pack it in the lockers when you're done working on it! The atmosphere is fundamentally collaborative. It can't be anything except participatory because of the way the spaces are most often organized and run. There is no single owner. Everyone pays for a portion of the rent, and more importantly everyone brings something new to the table. They might bring with them a new tool, their coffee machine, a desire to set up a program to run a STEM program for children. The spaces become a snapshot the local community of amazing people and their projects. Many of these people started developing their projects during their final years in university. But their is a gap between a school project and feeling capable to take it and turn it into something yourself. I'd love to start here. With these fresh graduates. These young people who (perhaps not coincidentally) are also the driving force behind the revolutions of the middle east. This is a great place to start. These are the young people changing their countries today. They feel empowered to change long standing traditions and the culture of oppression in their governments. Perhaps it's also time to give them the tools to do the same for their local communities. Where they have the ability to have a more direct impact. Who the heck cares about the government if you are free to repave your roads, create alternative energy from solar power, clean your own water and start your own online webstore distributing products that are rapidly prototyped and drop shipped to other places around the world. Sure you might call this line of reasoning anarchistic. But when the systems around you are falling apart, banding together to pick up the pieces is the admirable thing to do. Social entrepreneurship in the states often focuses on countries outside the states. They basically act as for profit NGOs. Non profit organizations as they operate in America don't exist in the middle east. Thus I'm beginning to think that the concept of social entrepreneurship might just be a great way forward for these countries. Doing well by doing good! This concept is a development hack, and one that could possibly have it's roots in the Hackerspace scene. There are features of hackerspaces that I see can give rise to more DIY social entrepreneurship in the middle east. They are: 1) The culture of good. Make something wonderful. Share it with others online and off. Be inspired and inspiring. 2) The availability of tools along with the docracy culture. If you want to see it, do it. 3) A supportive global and local community which has within it stories of other successes to emulate. Where does this culture come from? It appears to be derived from the open source movement. Open source technology is often spearheaded by a few individuals but is maintained, built and supported by a global community of makers who want the tech for themselves as well. Do you want to see that feature? Write it? But don't edit the program and keep it to yourself! Share! That's a doocracy combined with the culture of sharing that the internet helps so much to support. All of this seems to be directed by the common value for people of all ideologies. The golden rule. Do for others as you wish to have done for yourself. Do you want free tools. Freedom. Access to clean water? A cheap space to build projects? Free vector drawing software? Be a doer. Be a part of the change. And then share with others. Your vision is what makes the future. These are some of the amazing features of these spaces. This is why I am in love with hackerspaces, open source technology and makers of all types. They are beautiful people who come from all types of backgrounds who get together to create a culture of sharing and collaboration that enhances their local communities and connects them globally. If you have not visited your local hackerspace yet, visit it. If you live in a place without a space, put your name up on hackerspaces.org, I'm sure you will find like minded people who crave this type of community. Hackerspaces in the Middle East Now that we have described hacker culture and hackerspaces can a space like this become a the hub and home of amazing people in the Middle East? Does the west have a monopoly on awesome. Absolutely not. Are middle easterners creative Heck yes! Are they inspired to work collaboratively? Heck yes! Are they educated? Heck yes! Do they want to fix the problems they see around them? Heck YES! Are they powerful? Heck YES! Again and again I've seen example after example of the young people in the middle east (yes, those that are 30% unemployed) showcasing example after example of incredible projects. And talking to them a message I hear over and over is that they want to show the world that in Beirut, Baghdad, or Cairo things other than violence is created. They want to create positive news that goes out to the world. They want to reach out to the world and participate in sharing! Here's a short list of incredible people I've met personally in my two short trips to the middle east: Bassam Jalgha Tarek Ahmed Ahmed Tohamy Salma Adel Rami Ali's Smart Breadboard Marc Farra Maya Kreidieh Cairo Hackerspace Book Scanner Project An awesome home automation system in Baghdad Iraq Mustafa Elnagar Furkan Alp Pehlivan Hind Hobeika's Butterfleye Project Jad Berro's Tank Robot Mounir Zoorob Octocopter! Here's a video of Munir's octocopter: Beirut is beautiful: One incredible graduation project by Cairo Hackerspace organizer Salma Adel is one that focuses on the very heart of the maker movement and looks at the artisan as the creator of value. How do you take new design, match it with old technology and create amazing new products. I'm proud to know she's an active memeber at Cairo Hackerspace: I hope I have shown you that there are already "hackers", makers and entrepreneurs there in the middle east. People with the open source attitude Arabs with the culture of sharing and collaboration. There are many here that work with the Google Technology User Groups or other open source initiatives. Linux user groups. Tons of coworking spaces. And some incredible incubators and entrepreneurship cultural development projects. Android phones are more popular in Egypt than the iPhone from my own small survey. It might have initially started as a cost issue has turned into a passion with Ubuntu, firefox, Android and other open source technologies really taking off. A few things were missing though. If you read hacker news you will begin to think that anyone with a desire to make foursquare mashups is an entrepreneur. In the middle east we have incredibly skilled people languishing after college while their counter parts in the west are out attempting to recreate Facebook. Why?! I think it has to do with the lack of proper story telling about entrepreneurship in the Middle East. Wamda seems to be helping greatly in that regard, but we need more publications talking about this issue! This also comes in concert with an inability to find cofounders. Why? A lack of collaboration? Why? A lack of self initiated projects? Solution? Do stuff. Just do it. Where? Here. At your local hackerspace. Do you have an interesting idea you want to try? A drone to take ariel pictures of the pyramids? Or a service like Utlub which delivers soap to bathers who are wet and realize they ran out of soap. Well in a space like a hackerspace you can do it! The tools are there. But more importantly you will find collaborators! People who are willing to jump on board to help!al Patterns of Propagation The Arab world is not just ready for Hacker culture, hacker culture is already there. My work with GEMSI is simply to connect the right people together and showcase the awesome possibilities hackerspace afford their communities and attempt to create the right environment to allow these amazing people to take their own future into their hands like they already are, but to do it not only politically, but financially, and with direct community education and organizing. Before I went to the middle east I was privileged to participate in the rise of the hackerspace movement in the United States. In 2007 there were very few (if any self identified) hackerspaces in the United States. That same year Mitch Altman, Bre Pettis, and Nick Farr went on a trip to Germany visiting the hackerspaces that were there. Being filled with inspiration and the realization that these spaces were created by PEOPLE who wanted to set them up. They came back to the states and started Noisebridge, NYCResistor and HacDC respectively. Due to the culture of sharing, they started putting up projects online. They shared the process of creating these spaces. And slowly at first people started noticing that they too could start their own local community spaces for creation and we started seeing them grow rapidly. The mathematical name of the function that describes this type of growth is exponential. The more spaces that existed that have this culture of sharing the more people heard about them and wanted them in their own cities. Then something wonderful happened. The economy collapsed in 2008 which had two very positive effects on the development of hackerspaces: People were freed from their jobs Space was becoming cheap as tons of manufacturing facilities were abandoned. Check out this chart which shows the rapid growth of hackerspaces and the acceleration around 2008/9. Hacker culture is an attitude that anything can be done by any resource available. MacGyver will make you a mouse trap from your sunglasses and your underpants. A hacker would use it to make a one way privacy screen for your cellphone. But how do you transmit a culture? This is why a space is so important. Having a place where people can sit with others and recognize the possibilities. To see the value in the stuff they know, to share it with others and to build together. The first few hackerspaces that are being set up in the middle east have the same property of viral transmission as we saw in America. Istanbul Hackerspace and Base Istanbul are both hackerspaces in Turkey. Istanbul Hackerspace being in the European part and Base Istanbul in asian section. As widely spread apart as they are, they both have something in common. Both founders had visited a hackerspace, one in Japan and the other in Germany before coming home and deciding they wanted to start one there. It's kind of incredible to see the same pattern repeat in the middle east. This appears to be a universal need, the need for community, creativity and having a open space to build your future. The pattern has been proven in Egypt as well. Alexandria's hackerspace initiative was galvanized after a delegation of students visited Cairo Hackerspace two hours to the south. It's exciting to see the very same forces at work that took the hackerspaces from being a concept barely known to having a large impact on the American Entrepreneurial and cultural landscape in five short years years at work in Egypt. Cairo Hackerspace currently is without their space but is actively seeking a new one and it's one of my current goals to help in any way I can. Let's conclude with the list of hackerspaces just starting up in Egypt and Beirut. This is just the start. Keep an eye on these guys and know that there will be many many more to come: Egypt: Cairo Hackerspace El Minya Hackerspace Alexandria Hackerspace Mansoura Hackerspace Egypt Fablab (Same idea ;) Lebanon: Beirut Hackerspace (link coming soon) If you'd like to talk more about the global development of hackerspaces. Let's continue talking online at GEMSI's facbebook group. *Scrumspace does not exist as a hackerspace. If you like the name take it!

Last summer my top floor apartment was over 115 degrees indoors with blinds closed ! In a recent email to my landlord to report a broken mailbox I suggested the possibility of painting the apartment buildings roof white . In reward for reporting the mailbox he says I could paint the roof but only above my apartment . Cool . He says that the insulation was not adequate when built . The apartment has also gotten down to 30' in winter so I can only guess how cold it would get in here without the current black roof. QUESTION ; Are there any ideas to help solve both seasonal issues ? I can't re-insulate because I rent . I was thinking of a retractable white cover for hot summer days that can be removed in autumn . Or maybe even a white paint that would insulate against cold ?? An original idea was something like Bubble foil but I doubt that would stand up to weather. Any suggestion would be great .

I may be off on a tangent to reality, but I wonder if there are any statistics available on the effect of all the Tonnage Oxygen plants around the world sucking in all the oxygen, separating the various gases & storing them in pressurised liquid form. I did a quick search today and 2 countries alone were 'manufacturing' (sucking in our air, separating the elements and producing) 26,000 tonnes of approximately 99% pure oxygen per day! To the crux of my question: Is this action (carried out on a worldwide scale and potentially growing) upsetting the balance of our atmosphere - we are all informed by the press and by the scientists that global warming is (or may be) attributed to mankind burning fossil fuels and dumping the excess carbons into the atmosphere. I just view this as the flip side of the argument........ has anyone ever considered the tonnage of oxygen drawn in from the atmosphere by these plants which is sold-on essentially as bottled gas or piped to be used for oxidising other materials (blast furnaces, basic oxygen steel-making, scrap cutting etc), could be having an equal or bigger impact on our atmosphere and global warming than the straight burning of fossil fuels by power stations and automobiles etc? Just 'throwing the idea out there' (Liquid oxygen when spilt and viewed as a puddle, appears blue like the sky, the deeper the oxygen puddle, the more vivid the blue became ..... reminded me of when I was a kid the sky looked a lot bluer than it does these days).

Ethanol is under fire again: At first blush, biofuels such as corn ethanol and soybean diesel seem like they would be great from the standpoint of global warming. The crops soak up carbon dioxide from the atmosphere as they grow, and that balances out the carbon dioxide they produce when they're burned. But until now, nobody has fully analyzed all the ripple effects of this industry. And Tim Searchinger, a visiting scholar at Princeton University, says those effects turn out to be huge. "The simplest explanation is that when we divert our corn or soybeans to fuel, if people around the world are going to continue to eat the same amount that they're already eating, you have to replace that food somewhere else," Searchinger says.Searchinger and his colleagues looked globally to figure out where the new cropland is coming from, as American farmers produce fuel crops where they used to grow food. The answer is that biofuel production here is driving agriculture to expand in other parts of the world."That's done in a significant part by burning down forests, plowing up grasslands. That releases a great deal of carbon dioxide," Searchinger says.In fact, Searchinger's group's study, published online by Science magazine, shows those actions end up releasing huge amounts of carbon dioxide. The study finds that over a 30-year span, biofuels end up contributing twice as much carbon dioxide to the air as that amount of gasoline would, when you add in the global effects.

Via The Sietch BlogIf I asked you if giving up your car and plane travel (permanently) was a sensible solution to global warming, most people of adult age (lets say 20+) would have a hard time doing that. However the next generation, the ones who are really going to be screwed by the ill effects of the global climate crisis see things a little differently."new generation of green teenagers are prepared to support radical measures to help the planet, says a new study.A survey of 16- to 19-year-olds by the Future Foundation found more than one in eight (13%) supported a ban on travelling by air for leisure purposes, while one in 10 say they would back a ban on cars if global warming continues to worsen.Almost 10% even say they would be prepared to take part in guerrilla activities carried out by environmental groups.Meanwhile others - primarily girls - are so eco-conscious they have developed a whole new strand of teen insecurity: "green angst", defined as anxiety about one's eco credentials. Others said environmental awareness even influences their choice of friends and partners.The report was conducted on behalf of the National Lottery to inform funding of environmental projects."It might sound like these kids have lost their minds, supporting guerrilla organizations?! But when you consider the kind of world they are going to inherit it makes perfect sense. If you knew that your parents generation was going to leave you a doomed world, you might be a little pissed. No one wants to grow up to inhabit a mad max movie.According to the study released today by The National Lottery (UK organization), half of 16-19 year olds (50 per cent) want plastic bags banned completely, 71 per cent think that unnecessary packaging on food should go, and 13% per cent want a ban on traveling by plane for leisure purposes. While a quarter (24 per cent) think there should be increases on the taxes and tolls affecting cars, one in ten is prepared to go even further and would support a complete ban on cars if global warming continues to get worse.Read more here.

XinCheJian (http://xinchejian.com), the first Hackerspace in China, is one of the 30 Hackerspaces across the globe that have been selected to participate in the Great Global Hackerspace Challenge (GGHC) competition. The objective of the competition is to create an electronics build that will make a real and positive difference in an educational establishment. The competition runs for six weeks, from Monday March 21st to April 30th 2011. The winning project is evaluated on the following: How reproducible is the final project? How easily can the parts be sourced in locations around the world? How low cost is the final output? How well are the plans documented? How relevant is the project to helping education today? How inventive and creative is the design and build of the project? The selection of our participation proposal includes a 5900 RMB (US$900) budget in electronic components (including the required microcontroller and portable power source) generously provided by element14.com. Every Hackerspace that completes their project receives 10 soldering setups while the three semi-finalist Hackerspaces will each receive over 13000 RMB (US$2000) worth of electronic tools. The Hackerspace with the winning project gets a Tektronix MSO2024 oscilloscope worth over 36000 RMB (around US$5,600)! As an extra incentive, semi-finalists will be invited at the California Maker Faire 2011. To address the objectives of the competition, XinCheJian will focus on getting elementary and/or high school students acquainted with the intellectual processes of cooperative problem solving with out-of-the-box thinking. This will translate into an interactive and intelligent educational toy that stimulates students into a variety of challenging experiences. Want to join or help our team?

For example, I am trying to create a program where there are multiple questions on serial-mon and the user can input his/her answer in. "How to spell 1?" one (this is the answer) "How to spell 30?" thirty (this is the answer) I am trying to make my serial- mon page look like that.

I've been a using the new editor, and I think it's a big improvement over the old one. Is there a way I can use it by default? Yes I know it is but one click from the old editor, but by nature I'm a very energy consumption conscious person (aka lazy), and I'd prefer not to expend that 0.25 food calorie on clicking the "try New Editor" button. So how can I reduce global warming and use it by default?

Last year, WIkiversity opened as an initiative of Wikimedia foundation. I have just started the New Media Arts Wikiversity and everything is still to be created together. Most of the projects on instructables are instructive and though would be usefull on wikiversity which aim is not to accumulate definitions (like WIkipedia encyclopedia) but learning by doing. I encourage all Instructablers to join the wikiversity effort as Wikimedias are expected to become THE killer apps as educational ressources for the OLPC global project. JOIN !
