<span lang="EN-GB">Climate change has a massive impact on
water security in regions which are dependent on glacial runoff water in the
dry season. A large portion of China gets its dry season water from melting
glaciers in the Tibetan plateau. Various other countries in Asia, South America
and Africa are also dependent on glacial runoff. Unfortunately, due to global
warming, vitally important glaciers around the world have already shrunk by
20-80%.<o:p></o:p></span></div>

<span lang="EN-GB">Then there is the effect of our rapid
increases in consumption. Agriculture uses about 70% of the global freshwater
supply. A juicy 500 g steak, for example, needs a whopping 8000 litres of water
to produce. Due to the rapid increase in population and meat consumption,
global water demand is projected to exceed supply in two decades' time. Wonder
what we will do then…<o:p></o:p></span></div>

The only things that really seem to be taking off together with our consumption are stuff like depression, divorce, violent crime and teen suicide.<br /><br />Things scientifically correlated to happiness include health, relationships and job satisfaction. Beyond that which is needed for a comfortable life, material wealth is a very weak indicator of happiness.<br /><br />In summary, consumerism makes first world citizens consume like we had five planets and leave carbon footprints ten times that which is sustainable. It ruins personal health, finances and relationships. And, of course, it brings absolutely zero happiness. So in order to be happier and help us reach a sustainable society: watch this video, think, share and care!</span><div style="font-family: Georgia, serif; font-size: 100%; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal; "><span class="text_exposed_show" style="display: inline; font-family: 'lucida grande', tahoma, verdana, arial, sans-serif; font-size: 11px; line-height: 13px; background-color: rgb(255, 255, 255); "><br /></span></div><div><span class="text_exposed_show" style="display: inline; background-color: rgb(255, 255, 255); font-size: 11px; line-height: 13px;"><span><iframe width="430" height="315" src="http://www.youtube.com/embed/oGab38pKscw?rel=0" frameborder="0" allowfullscreen=""></iframe></span></span></div><div><span class="text_exposed_show" style="display: inline; background-color: rgb(255, 255, 255); font-size: 11px; line-height: 13px;"><span><br /></span></span></div><div><span class="text_exposed_show" style="display: inline; background-color: rgb(255, 255, 255); font-size: 11px; line-height: 13px;"><span>Thanks to Schalk Cloete for contribution.</span></span></div>Sunniva Bratt Slettehttp://www.blogger.com/profile/14571127321853521182noreply@blogger.comtag:blogger.com,1999:blog-6567651957831188880.post-65700297224878858242012-03-31T13:19:00.006-07:002012-03-31T13:34:56.158-07:00National student conference!<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTZCzNZ0i5765sLKTqRXrOQZ8WAz5tZdvndNq4iw4eIcHzdROGwbadUH_nK5BwbxgKKKedDNoz_48sZsFMbCmYtzFWYmfI5E12ZbProsocKpHYnMk8tisJYLsCWGGPw9i1GcdM4vsV2P4/s1600/25032012_006.jpg"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 320px; height: 228px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTZCzNZ0i5765sLKTqRXrOQZ8WAz5tZdvndNq4iw4eIcHzdROGwbadUH_nK5BwbxgKKKedDNoz_48sZsFMbCmYtzFWYmfI5E12ZbProsocKpHYnMk8tisJYLsCWGGPw9i1GcdM4vsV2P4/s320/25032012_006.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5726158754731184834" /></a>This is a snapshot from the surroundings of the national Start conference in Ålesund!

Food just magically appears on the shelves week after week after week. But is that really what happens? And will it last?<br /><br />Today, as Asian growth is just getting into its stride, world food production is already under pressure. Food prices are rising rapidly and, although it is nothing but an annoyance to us, it has a massive impact on poor people who spend the majority of their income on food. Close to half the world's population survives on less than $2 a day. Compare that to your daily food intake to get some perspective. <br /><br />Grains provide half of the world's caloric intake, but yet, we currently feed a third of our grains to livestock and use a sixth of it for biofuels. Global food demand will triple by 2050, Chinese meat consumption is doubling every seven years and biofuels might be our only hope when peak oil hits. Oh, and then there are of course the potentially disasterous effects of climate change on agricultural output… <br /><br />Eating and living sustainably saves lives. And your own health, which is a decent bonus...<br /><br /><iframe width="500" height="315" src="http://www.youtube.com/embed/F1IWkbU0SG4?rel=0" frameborder="0" allowfullscreen></iframe>Sunniva Bratt Slettehttp://www.blogger.com/profile/14571127321853521182noreply@blogger.comtag:blogger.com,1999:blog-6567651957831188880.post-42585880322502393042012-03-10T10:57:00.003-08:002012-03-10T11:00:27.954-08:00Climate change post 13: Planetary boundaries<span style="font-style: normal; font-variant: normal; font-weight: normal; font-family: 'lucida grande', tahoma, verdana, arial, sans-serif; font-size: 11px; line-height: 13px; background-color: rgb(255, 255, 255); ">Scientist and guest writer Schalk Cloete continues with the climate change post series: </span><div><span style="font-style: normal; font-variant: normal; font-weight: normal; font-family: 'lucida grande', tahoma, verdana, arial, sans-serif; font-size: 11px; line-height: 13px; background-color: rgb(255, 255, 255); "><br /></span></div><div><span style="font-style: normal; font-variant: normal; font-weight: normal; font-family: 'lucida grande', tahoma, verdana, arial, sans-serif; font-size: 11px; line-height: 13px; background-color: rgb(255, 255, 255); ">Our planet has unmovable physical boundaries – fixed maximum rates at which it can generate the resources we consume and process the wastes we produce.

The </span></span><span>prolonged</span><span> dry season back in 2007 caused a water level in the flooded forests five meters below normal.

Rightly so, as increased temperatures causes changed precipitation patterns, withdrawing glaciers in the Andes mountains and unpredictable water levels in the Amazon river. </span><span>Check out the first two minutes of this video for some more info!</span></span></p><p class="MsoNormal" style="font-style: normal; font-variant: normal; font-weight: normal; line-height: normal; "><span lang="EN-GB">Passing over to research scientist Schalk Cloete:</span></p> <p class="MsoNormal" style="font-style: normal; font-variant: normal; font-weight: normal; line-height: normal; "><span lang="EN-GB">"The Amazon contains about half of the entire planet's biodiversity, produces about a fifth of the world's oxygen and contains about a fifth of the planet's fresh water.

Here are just a few: Melting polar ice increasing heat absorption, collapse of the Amazon rainforest causing massive CO2 emissions, thawing of Siberian permafrost releasing megatons of methane, deep-sea methane hydrates exploding to the surface, and anoxic oceans releasing further (poisonous and flammable) greenhouse gasses.</span></p> <p class="MsoNormal" style="font-family: Georgia, serif; font-size: 100%; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal; "><span style="font-size: 100%; ">Each of these tipping points kick in at a different level of temperature rise and it is theorized that, once we cross enough of these tipping points, it will set off a self-strengthening cascade into oblivion. For example, the total collapse of the Amazon is projected at 3 degrees, which will push us over the Siberian permafrost tipping point, which will push us over the methane hydrate tipping point, which is projected to cause nothing short of a global cataclysm.</span><span style="font-size: 100%; "> </span></p> <p class="MsoNormal" style="font-family: Georgia, serif; font-size: 100%; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal; "><span lang="EN-GB" style="font-size: 100%; ">Enjoy the attached video of reasons to avoid all of this.

predict a rise between 2 and 6 degrees by 2100, having impacts ranging from severe to catastrophic. One such model study is reported in the attached video. It may look a bit boring at first, but please put it on HD, notice the scale at the bottom and really focus on what happens to the planet with and without CO2 emission reductions.</p> <p class="MsoNormal"><span lang="EN-GB">This particular model shows a lot of warming especially on the poles and on the continents in general.

Scary thoughts…</span></p> <p class="MsoNormal"><span lang="EN-GB">At this stage, we all still hope that these models are overly pessimistic and perhaps over-estimate the greenhouse effect.

Schalk Cloete has made an excellent series of climate change posts on Facebook. With the thoroughness of a true researcher he shows wise considerations about our current climatic situation, and with his permission I will share his posts with you:</p><p class="MsoNormal">"Here goes: The world emits 30 billion tonnes of CO2 yearly, amounting to about 15300 km3 in volume. At roughly 10 km thickness, the atmospheric volume is 5.11 billion km3. Dividing these two numbers reveals that humans raise the CO2 concentration by roughly 2.99 ppm yearly. Actual measured CO2 rises are around 2 ppm yearly, implying that the earth manages to absorb about a third of our emissions.</p> <p class="MsoNormal">CO2 is a greenhouse gas. This means that it allows short wavelength solar radiation in, but captures and randomly redistributes long wavelength infrared radiation re-emitted by the earth's surface. Naturally, the heat captured increases with the CO2 concentration, hence global temperatures increase with CO2 concentrations.</p> <p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span>97% of all peer-reviewed scientific literature agrees."</p><p class="MsoNormal">Whoa. How about we stop discussing whether or not global warming is manmade or not, but stick to the scientific research and start acting like we care?</p><p class="MsoNormal"><br /></p> <p class="MsoNormal"><iframe width="420" height="315" src="http://www.youtube.com/embed/EfG2VIKvieM?rel=0" frameborder="0" allowfullscreen=""></iframe> </p> <!--EndFragment-->Sunniva Bratt Slettehttp://www.blogger.com/profile/14571127321853521182noreply@blogger.comtag:blogger.com,1999:blog-6567651957831188880.post-74512475560395439582012-01-22T02:05:00.000-08:002012-01-22T06:05:13.299-08:00Future Earth: Part 1<iframe width="500" height="310" src="http://www.youtube.com/embed/Vkgp8yJnnRg" frameborder="0" allowfullscreen=""></iframe><div><br /></div><div><br /></div>Sunniva Bratt Slettehttp://www.blogger.com/profile/14571127321853521182noreply@blogger.comtag:blogger.com,1999:blog-6567651957831188880.post-82397609160990956372011-12-11T05:24:00.000-08:002012-01-24T10:38:51.383-08:00Magical medicine!<iframe width="530" height="315" src="http://www.youtube.com/embed/aUaInS6HIGo?rel=0&hd=1" frameborder="0" allowfullscreen=""></iframe><div><br /></div><div>I strongly recommend you to watch this!

There are several fascinating, worrying and interesting subjects brought back to my attention! Among them the effect food production has on the environment.<div><br /></div><div>For my international readers, the bar graph is in Norwegian, but I´ll explain:<br /><br />The image to the left is taken from one of our energy and environment-lectures. The bar graph gives an overview of the amount of CO2 emissions produced by various types of food. The scale is measured in grams CO2 equivalents per kg of the product. Not surprisingly, vegetables give very little emissions, while meat from cattle is by far worst. Cheese is the third worst, and vegetables grown in greenhouses give very high emissions compared to vegetables and fruit growing outside.<div><br /></div><div>In short: a low-carb diet is disastrous for the environment. A varied, balanced diet with lots of vegetables is the key to sustainability!</div></div>Sunniva Bratt Slettehttp://www.blogger.com/profile/14571127321853521182noreply@blogger.comtag:blogger.com,1999:blog-6567651957831188880.post-60180808879890657272011-12-03T14:02:00.000-08:002011-12-03T14:22:15.151-08:00Intelligent thermostat saves energy<iframe width="500" height="350" src="http://www.youtube.com/embed/5thQRIX3Rio?hd=1" frameborder="0" allowfullscreen=""></iframe><div><div><br /></div><div>Now here´s something I like!

This was the year we didn´t get snow in Norway until January. We´ve had the warmest November ever, and still the snow is delaying. I feel like emphasizing the depth of nature´s connected patterns yet again, though it should be obvious. See the National Snow and Ice Data Center for more info about Arctic ice levels <a href="http://nsidc.org/arcticseaicenews/">here</a>.<div><br /></div><div>I´m still amazed by humans ability to think incredibly short-sighted. How is it possible to ignore scientific knowledge because we have comfortable and cheap solutions within reach? How can it be so difficult to understand the need of sustainability? </div><div><br /></div><div>It´s quite logical really, the math is pretty straight-forward. I will repeat it, just in case. It all boils down to one thing: we don´t have more than one globe. The consequence is: we can´t use more than the limited resources accessible. One plus five never equals one.</div><div><br /></div><div><img src="http://upload.wikimedia.org/wikipedia/commons/thumb/b/b3/MonthlyMeanT.gif/300px-MonthlyMeanT.gif" border="0" alt="" style="float: right; margin-top: 0px; margin-right: 0px; margin-bottom: 10px; margin-left: 10px; cursor: pointer; width: 300px; height: 185px; " /></div><div>So we should use the resources available to develop sustainable solutions, which will last despite of population growth. Renewable will deliver energy for years and years ahead because we already have an unlimited power supply: the sun. In my eyes, developing yet other methods for squeezing the last drops of oil out of the already exhausted soil is madness. What we need is to think further than profit next year or decade, steering towards the "plan ahead"- mentality. Use natural and human resources for constructive solutions, not to create new problems which will delay the process more than absolutely necessary.</div><div><br /></div><div>Global sustainability and balance is required within several fields, but perhaps most importantly concerning environment and economy. The two are closely related, so regulating one in the right direction will have positive affects on the other.<br /><div><br /></div><div><br /></div></div>Sunniva Bratt Slettehttp://www.blogger.com/profile/14571127321853521182noreply@blogger.comtag:blogger.com,1999:blog-6567651957831188880.post-35996959576435871082011-11-05T03:47:00.001-07:002011-11-05T03:53:44.900-07:00Luna Solar Energy<div><span class="Apple-style-span"><iframe width="540" height="315" src="http://www.youtube.com/embed/TUL_rDeKIeU" frameborder="0" allowfullscreen=""></iframe></span></div><div><span class="Apple-style-span"><br /></span></div><div><span class="Apple-style-span"><span class="Apple-style-span">This is a visionary energy concept from </span><span class="Apple-style-span" style="font-family: arial; ">the </span><span class="Apple-style-span" style="font-family: arial; ">Japanese</span><span class="Apple-style-span" style="font-family: arial; "> Luna Ring Shimizu Corporation´s </span><span class="Apple-style-span" style="font-family: arial; ">researchers</span><span class="Apple-style-span" style="font-family: arial; ">.
