Follow COP21 live


This year the UN climate talks (COP21) are taking place in Paris from the 30th November to 11th December. The aim is to achieve a legally binding and universal agreement on climate with the aim of keeping global warming below 2 degrees C. There will be an estimated 50,000 participants including 25,000 official delegates. For those attending the aim is to stimulate interactions during the conference between the negotiators and representatives of Civil Society. Of course the remaining 7 billion of us won't be able to attend the conference, but thanks to the UN we will be able to follow the conference live at  http://unfccc6.meta-fusion.com/cop21/

A NASA funded project has identified that the massive Zachariae Isstrom, that represents 5% of the total Greenland ice sheet, broke loose from a stable position in 2012 started a phase of  accelerated retreat. The glacier drains ice from an area of 35,440 square miles (91,780 square kilometers), that is enough water to raise global sea level by more than 18 inches (46 centimeters) if it were to melt completely. The bottom of Zachariae Isstrom is being rapidly eroded by warmer ocean water mixed with growing amounts of meltwater from the ice sheet surface. Currently it is now losing 5 billion tons of ice and water every year into the North Atlantic Ocean. Jeremie Mouginot, an assistant researcher in the Department of Earth System Science at the University of California, Irvine who has published this study in Science says that the result of this glacier breaking up and calving high volumes of icebergs into the ocean, will result in rising sea levels for decades to come. Full report Link

Adjacent to this is another large glacier Nioghalvfjerdsfjorden which is melting at a slower rate, but together they make up 12% of the Greenland ice sheet, so together they will raise sea levels by more than 39 inches (99 centimeters) if they completely melt.

NASA has a new project - Oceans Melting Greenland- which is monitoring ocean conditions around Greenland. https://omg.jpl.nasa.gov/portal/

Facing Up To Global Warming Published

Facing Up To Global Warming: what is going on and how you can make a difference?


This new book was published today and  explores climate change and how individuals can make a difference. 

 Below is the Preface from the new book.



In 1972, a startling book was published called Limits to Growth . This book became hugely influential in the environmental movement, and while it alerted us to the fragility of our future on planet Earth, it also, inadvertently, helped to eventually undermine the credibility of environmentalism. The book predicted when certain non-renewables, including fossil fuels and metals, would become exhausted. The predictions were based on the best available knowledge at that time, but what it never envisaged in the early 1970’s, was that within a decade humans would be extracting oil, gas, and minerals in some of the remotest, extreme, and fragile places on Earth … a process that has continued and expanded to the present day. So the predictions proved incorrect in practice, but it reinforced the idea that all resources are limited and are slowly being exhausted.

This book became a driving force for many environmental scientists who realized that we have to act both collectively and individually to preserve our home, planet Earth, with its unique biosphere and which is home to millions of different living organisms of which we are just one species. For me personally, being an environmental scientist has been a long and often disappointing journey and at various times I have been shocked, scared, and often depressed by the unfolding of the current crisis which is so intertwined with global warming. But, to my surprise, in recent years I have begun to feel more hopeful that perhaps we can deal with our climate and resource problems to create a sustainable planet. So in this book, I have attempted to explain what the problems are and suggest some solutions. However, the book comes with a warning. During the 15 chapters that follow, I am going to make a lot of you really annoyed and possibly upset, I apologize in advance. I am not trying to shock; I am simply putting the facts before you so that you can make up your own mind. Neither am I telling anyone that their lifestyle is wrong, or alternatively, that they are better than the next person because they have invested in green energy or a hybrid car. The book is an overview; it is not a text on the theory of sustainability or population dynamics; it simply looks at what the individual should know and addresses some of the issues closest to our everyday lives.

There are hundreds of academic and specialist texts on sustainability, but they fail to link sustainability to tackling global warming, especially at the individual level. Adopting any form of sustainable actions in your life will cause significant effects both direct and indirect. Such actions will lead to changes that will influence economic and social norms … so sustainability if properly applied will mean socio economic change. I begin the text by giving a brief overview of the problems of climate change and the real difficulties that having such a rapidly growing population is placing on the idea of a sustainable and equitable planet. Discussions on population is always a very emotive issue and so I have simply given some basic facts, and shown that as population grows our ability to live sustainably on planet Earth becomes more challenging. So this is not a comfortable book.

Is the text political? I have tried not to be, but if you advocate changing people’s lifestyles, then it will appear to be political. Then, we have the concept that everyone on the planet matters and that the concept of global justice and human rights is important when assessing the sustainability of our own lifestyles. So trying to avert these climate-mediated crises by ensuring that everyone has enough for their needs without being wasteful is a good starting point. However, that starting point has to be an acknowledgment that all people are equal, and that we should all have the right to pursue happiness and well-being. Is this naïve? Of course it is, but what else are we to strive for in a truly global and fair society. Global warming raises serious social as well as economic questions and many of these are going to be very difficult to deal with in practice, and my aim is to try and make you think about these issues from a personal perspective. Can we have finite economic growth? Can we have finite consumerism? Unfortunately, the answer has to be no to both of these questions, which means that both economists and social geographers or planners have a lot of work to do and that we are going to have to eventually reinvent our economy and social environment to achieve these goals.

There are also many other important environmental issues that we also need to consider and many of these are also linked to global warming such as deforestation, exploitation of new fossil fuel reserves, intensification of agriculture, and overexploitation of water resources. However, many of these issues such as pollution, are less important in the context of global warming, as we now have them largely under control. We have made huge strides in dealing with air, water, and land pollution over the past 40 years, and there are scientists and regulatory bodies all dealing with these issues on an on-going basis. Such issues are predominately local or at worst regional, but rarely global, and what is important is that we have the technology and infrastructure to deal with them. But controlling carbon dioxide and other greenhouse gas emissions must now be everyone’s priority. If we have to reduce carbon emissions by 80 % by 2050 to avert a global crisis, this will mean using significantly less energy in the developed world than we currently use, and while this does not necessarily mean an immediate and huge change in our everyday lives, it does mean changes to our current lifestyles. This is not going to be easy and the burden has to be shared by everyone. However, the fact is that people feel very threatened by the idea of altering their lifestyle, even when change can be for the better. 

We also need to understand that some sectors of society are using more than their fair share of global resources, but that in the context of global warming everyone must act responsibly if we are to succeed in mitigating climate change. Those in developing countries also desire the technology, food, travel, etc. we enjoy, and to break this cycle we in the developed world need to begin to pull back from our current high-energy lifestyle while allowing the poorer nations to develop and become sustainable.

This book will never be welcomed by those who are pretty happy with the status quo and who have not become genuinely concerned, possibly scared, by the possibility of what global warming may do to our home, planet Earth. This is a very general text that looks at different aspects of our lives which we, as individuals, have control over. It is simple things like travel, food, recycling, using resources … all those things which we are all involved in on a daily basis; and how our actions affect the future of planet Earth and our ability to sustain that ever growing human population. I hope that this book will help you think and act from a position of knowledge and reassurance.

I hope that the majority of you will be reassured that we are beginning to tackle global warming successfully, but in order to succeed in stabilizing our new climate, and I believe we can, we need your help through direct action. You really can make a difference. This book is a personal journey and during it I will be asking you to do various things. Some are critical others will be just things that I hope you will try, but to work, I need a commitment from you. The journey is not free, it comes at a cost, and you have to decide just how much you are willing to pay for your planet.


This is about your future.

Strange Weather Exhibition at the Dublin Science Gallery

The latest exhibition at the Science Gallery at Trinity College Dublin is STRANGE WEATHER.

The exhibition runs from the 18th July until the 5th September and  is curated by Catherine Kramer and Zack Denfeld of CoClimate; Lynn Scarff, Director of the Science gallery and Gerald Fleming, Head of Forecasting at Met Éireann.  Like all these wonderful exhibitions at the Gallery it is most informative and very much hands on. So you can have a try at forecasting the weather yourself, create your own micro-climates and learn just how predictable the future of weather is.

Irish farming and climate change

Irish farming will be affected by climate change but not as severely as more southern countries.  The problems will primarily be the reduction in summer rainfall by up to 25% and an increase in winter rainfall by 17% by mid century, with Southern and Eastern counties most affected.  This will  result in extended dry periods leading to drought, flooding, heavy rainfall events and extreme temperatures, in fact far more unpredictable weather patterns making farming activities difficult to plan and execute.  While this will mainly make tillage farming more difficult from sowing to harvesting of crops, livestock farmers will also feel the pressure from increased stress to animals  and providing water in the summer to ensuring sufficient winter fodder.  The wet summer of 2012 led to a massive fodder crisis in some parts of the country during the winter and spring of 2012/13, leading to massive imports of hay and silage from the UK and Europe. The increased prevalence of pests and diseases ,especially new pests as their ranges increase in response to higher temperatures, will affect all farming sectors.   It is not all negative because the higher temperatures will increase cereal and beet yields, which is in stark comparison to countries such as Romania and Hungary which will see a steep decline in crop yields due to water scarcity.  The solution is for the Irish farming sector  to  increase crop diversity, alter planting and harvesting regimes, develop more climate resilient crops, and to introduce water management strategies.

Consumerism: The enemy of the environment

The first decade of the 21st century saw the emergence of the importance of protecting our environment. Being part of the school system at the time meant watching as curriculums changed and seeing notices over light switches to remind the teachers about the new measures in place. I remember when recycling became more than just a phenomenon, it became a way of life. I recall wondering which bin my bottle went in to, until finally it all became second nature. For my generation, climate change is something that has been a part of our lives as we grew up.
Everyone knows that climate change is not something to joke about. Why is it then, that in approaches to climate change, it is always the economic impact that is considered first? Our finite resources such as oil are under risk and will run out relatively soon, yet we continue to burn through our resources at an alarming rate. Our sea-levels are rising, our species are dying out and we have reduced freshwater availability. These are only the beginning of the long list of climate change effects. Yet we constantly need a reason to make change. When considering making changes to our lifestyle to benefit the environment, the incentives are always economical – how much money will we save?
News outlets and politicians use buzz words like “environmentally friendly” or “climate change aware” but they have been thrown around for so long that they have lost all impact or meaning. No one seems to comprehend the extremities we are facing if our current pace of life does not change.  As a geography student myself, I am aware that the impact our current way of life has on the environment around us is vast. However, I was unaware of the EXTENT to which our resources are running out.
Consumerism has engulfed the developed world and millions of jobs are focused on selling the consumer products and convincing them that they always need more. Marketing campaigns that depict happiness upon purchase of a certain product place pressure on consumers to consistently be purchasing their new product, or they will not achieve this generated form of contentment.

Technological advances, though beneficial in many respects, feed into this consumerist lifestyle; the consistent desire to have the latest gadget. Our daily lives are consumerist driven, even on a college basis. Walking around with coffee cup in hand is no longer a source of refreshment, but a fashion necessity. The pressure to have a smartphone is outstanding, while a new laptop every year is a must. Wearing the same outfit twice in one week is unprecedented and accessories are expected to change all the time.
 

A busy shopping mall, another example of our consumerist society.
Why is leading a sustainable lifestyle not fashionable? As a global community, we need to generalise the idea of living a life where your demands on the planet are at a reasonable rate. The phenomenon of doing more with less is not scientifically startling, but it is challenging. I am of the belief that by a combined volume of small efforts, climate change can be tackled head on. Everyone knows that you shouldn’t leave the tap on when you’re brushing your teeth and that lights should be switched off upon exiting a room, but these were the things introduced when this climate change phenomenon started more than a decade ago. Surely we have made more advancement since then?
The next decade will be challenging for economists and environmentalists alike. While economists attempt to predict the financial future of the developed world, environmentalists will be trying to predict how much longer we have on the planet before something has to give. The experts in both fields need to take each other’s concerns on board, and recognise the validity of the alternative area of expertise. By combining the knowledge of two fields of people, a more feasible way of dealing with our every changing climate can be devised. Hopefully this will come into place before it is too late.

Re-educating the Family

 “Aaahhhhhhhhh….”. The exasperated sigh of a man whose eco-friendly advice falls on deaf ears. As a student of geography I find myself more aware of the current and developing problems associated with the environment in modern life and attempt to do what little I can do (without going completely out of my way, I’ll admit I’m not fully dedicated to the cause) to alleviate some of the stresses I personally inflict upon the environment. The little things such as short showers, flicking the light switch off, ensuring the recycling is done properly and plugging out all unnecessary plugs. As you can clearly tell, I’m not claiming to be the most eco-friendly person that’s ever lived but I’m certainly putting an effort in.

I have tried to instil some of these morals to the rest of my family but they either love to ignore my increasingly persistent advice or simply choose to do the opposite of what I’ve suggested. Each family member has their own bad habits that they just refuse to break. My sister and I have had more fights over her leaving the shower running for 5 minutes, with no one in it, simply to “warm it up” as she says. Apparently it’s different to when I take a shower because when I do it warms up in a matter of seconds. She also is a fan of leaving lights, TV’s and stereos perpetually on. Sometimes I feel that my only job in the house is to turn objects off after her. My Mam seems to have a particular disliking for the recycling. No matter how many times I show her that cardboard, tins and types of plastic go in to the green bin, I’ll still find the aforementioned objects in the kitchen bin when I’m throwing something (within the right category) into it. My Dad has a particular attachment to his car and has been commuting to work for it in years. I can’t remember the number of times I’ve told him to start using public transport at the very least and he has stoically ignored. This is the one place I’ve seen improvement however as one day, out of the blue, he bought himself a decent bike and began cycling to work and has kept it up since. Up until that point I felt my mission of attempting to “green” up my family was futile as no one listened but if I could convince my dad to make a pretty dramatic switch, I feel the rest is within my reach too. I understood, to a minute degree, what it felt like to be an environmentalist in the world we live in today. The majority of your advice is being ignored, simply for convenience purposes, but occasionally you can get through and make a difference. No matter how insignificant it may seem, a drop of water still changes the level.

Controlling Wildfires – Sustainable for Who?

When people speak of sustainability they speak with the idea of creating a planet resourceful for all species, not just man. The human race will probably admit to being the leading cause of the disruption of sustainability so it’s fair that we also take responsibility to try repair it, not just for us but for all other organisms that inhabit earth. But what inspired me to write about this particular topic was that man is also trying to repair the disruption caused by other sources on the planet.

So what are the main disruptors of sustainability? Overpopulation, destruction of forests, burning of fossil fuels… all caused by man mainly. As a result of all these and many more, there is too much carbon being pumped into our atmosphere causing more disruption.  But we all know that and we are slowly trying to change ourselves to decrease our carbon emissions. Natural sources of carbon emissions however can’t change themselves and we’ve generously decided to also help combat their carbon emissions. But is this an entirely beneficial thing? Is this really sustainable for the entire planet or just us?

Wildfires are thought to cover 3–4 million km2 of the globe each year and are responsible for the release of 2–3 billion tonnes of carbon to the atmosphere based on estimates from previous years. I think everyone can agree that this is bad and due to global temperatures rising, forests are becoming drier and more prone to more frequent and larger fires. But do we really have the right to try stop these natural occurrences?

Despite the billions of tonnes of carbon emissions, wildfires do have their benefits, of which many species take advantage. It is said that fires cause the loss of nutrients through a variety of mechanisms however it has been shown that very high temperatures have to be reached to result in a significant loss and generally these nutrients are replaced by the organic matter left behind after the fire. Fires also remove overhead vegetation resulting in fewer leaves intercepting rain which allows more moisture to reach the soil.

It is also said that fires result in the loss of biodiversity due to the death of species caught in the fires. This has been shown incorrect in many cases. The longleaf pine savannas of the southern states of America depend on fire to prevent the invasion of deciduous forest trees whose shade eliminates both the pines and the species beneath. The diversity and abundance of these species is closely related to fire frequency. Natural fire regimes of the forests of British Columbia are important in maintaining a diverse assemblage of vertebrate species and different species have adapted to exploit the different stages of succession, regrowth and habitat change that occurs following a fire. Fires also cause the habitat to evolve differentially afterwards and influence how vertebrate species are able to use the burned areas. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. There are also many plant species that depend on fires to instigate the germination of their seeds such as the Giant Sequoia.

Fire serves many important functions within fire-adapted ecosystems. Fire plays an important role in nutrient cycling, diversity maintenance and habitat structure. The suppression of fire can lead to unforeseen changes in ecosystems that often adversely affect the plants, animals and humans that depend upon that habitat. So with all that in mind, is controlling wildfires creating sustainability for all or are we just looking at the smaller picture?

RAIN HARVESTING: HAVE YOU HEARD OF IT YET?


Source: http://kscst.org.in/
Last weekend I had the pleasure of looking out the window to endless hours of rain. It dawned on me that each house in my estate was failing to take advantage of  the potential savings to be made from the water falling from the sky. Out of shear boredom I decided to collect the rainwater in an old oil drum and then a few days later use this water to water the flower beds in the garden with a jerry can. Although it was unnecessary as the garden was saturated from the previous few days of rain, I carried out the task in order to evaluate the practicality of collecting rain water in order to utilise it for mundane water consuming tasks, such as watering the flowers. Not to my surprise, there were ample amounts of water for the plants and even a bit to spare.
This set me thinking of how feasible would it be to construct a water collecting unit in my back garden (possibly on the shed roof to take advantage of the forces of gravity), to which one could attach a hose pipe (I believe jerry cans to be a bit out dated) and hey presto you have a free water source. This may seem totally irrelevant at present but when water meters are introduced, and money is leaking from that external back garden tap then we will see the method in the madness.
The idea of collecting rainwater in order to use for mundane tasks extends beyond your mother’s flower bed (or even your own). There is no reason why rainwater can’t be used to wash a car, fill a water balloon or even clean the decking. It is evident that more sustainable methods of consumption (in this case for water consumption) exist all around us, it just requires a little ingenuity and innovation to realise a more practical and sustainable way of life.
When I eventually got around to researching “rain harvesting”, as it turned out to be called, I discovered that there already exists numerous companies providing such services (below are links to some of their websites). However, such companies appear to be under the radar with regards to public interests. No doubt this will change with some clever marketing post the introduction of water meters to Irish households in the near future.
To give some gravitas to my argument, the following quote taken from the Irish Water Treatment Association’s website, highlights, in my view, the necessity and complete feasibility of rain harvesting in Ireland;
‘Much of the water we use doesn't need to be of drinking quality. In fact studies show that 55 per cent of domestic treated water could be substituted for rainwater while 85 per cent of water used for commerce and industry does not need to be of drinking standard’.

It makes all the sense in the world, right? Even the ancients were at it!

Reduce your carbon Paw print: Tips for greening up your pet


I can be green too!

In 2009, a couple from New Zealand, Robert and Brenda Vale, wrote a book called ‘Time to Eat the Dog?’ in which they discussed the devastating effect that being careless with how you care for you pet can have on the environment.  According to the book, the carbon paw print of a pet dog is double that of your standard SUV, making man's best friend the environment's worst enemy. Other pets targeted were hamsters, which were compared to a plasma television, and goldfish, which actually burn energy equivalent to two cell phones. With a few small changes to how you care for your animals, you can help reduce your carbon footprint by reducing their carbon paw print.

1: Adopt Pets
There are plenty of lovely pets just waiting in animal shelters to find new homes. As well as doing good, by adopting you are also reducing the demand for pets from mills, which have large carbon footprints due to their use of low-grade food (the production of which has high carbon emissions).
2: Recycle and Reuse
Lend a helping hand. Instead of binning your old toys, beds and accessories when your pet grows out of them (or just tired of them), drop them up to your local pet shelter. Not only is this better for the environment but you will also be helping out very worthy charities. You could also swap old pet accessories among your neighbours or friends who are also pet owners.
3: Pick up Waste
Instead of using plastic bags to pick up your dog waste, opt for biodegradable bags that break down in about a month – a lot better than the 1500 years it takes plastic to degrade. If you have cats, think about switching to an organic, plant-based litter.
4: Walk to Walks
Why drive your dog around to bring them for a walk? Look for parks and open spaces nearer to your house to reduce emissions. If you need to drive, try to carpool with other dog owners.
5: Buy them Green Goods
These days, eco-friendly pet accessories are everywhere. When buying your pets toys, look for toys made from recycled materials or sustainable fibres such as hemp. You can also buy hemp collars and leads, which are much better than the more common plastic or leather. You can also get beds made from organic materials or recycled PET bottles. Failing this, use old towels or cushions to make your own eco-friendly pet bed.
6: Be Careful about Food
When buying pet food, opt for higher-quality foods, which have used sustainable methods and are conscious of their carbon footprint when producing it. Take the time to read the labels on all pet food packaging, and look for foods that do not contain synthetic ingredients or chemically altered natural ingredients. Buy chicken and rabbit flavours over beef, which will also lower your pet’s carbon paw print. As well as this, try your hand at using up scraps of old food and vegetables to make your own dog treats. You’ll save money and also reduce your waste by using up odds and ends and not having excess packaging from store-bought goods. When you are buying pet food, buy in bulk to reduce the packaging.

The 21st century, The age of expiration!

I-phones, I-pads, MRI scanners, solar panels, computer chips, superconductors and spacecrafts, if I asked you what do all of these objects have in common what would you say? That they are all examples of technology, the age of science, products that are improving our lives and future? This all may be true but the answer I was looking for was that all of these products may not be around in the next century.
It may seem bizarre that objects that we associate as symbols of the future may not be around in the future. The rare earth metals and gases used to manufacture these products are non-renewable and are only present on earth in finite amounts. Helium which is critical for superconductors, space exploration and medical technology will run out in 25 years. Global hafnium supplies, which are utilised in the manufacturing of the chip in this computer, is predicted to be exhausted by 2017 (yes,it is the year 2013 now!) The screen you may be reading this off may be an LCD screen and if so say goodbye as indium, the main component, will be exhausted by 2020. Zinc...2037, uranium...2090, copper...2100...
It is disheartening, especially to me as a scientist, that the major advances of the past few years in medicine, nano-and micro-technology will probably not be commercially viable to expand on due to the lack of rare metals, that the recent advances in renewable energy such as hybrid batteries, energy-efficient lighting and solar panels will ironically come to a halt as the non-renewable resources used exhaust. But as well as being disheartened, a worry has begun to creep in as I consider how we are beginning to depend on these new technologies. 28% of helium supplies are used to super-cool magnets for MRI scanners. What will happen when this runs out in less than 30 years? Does anyone have a back-up plan?
We claim to be a caring species who are trying to live sustainably so that the future generations, our children and grandchildren, can have the chance to experience the amazing world that we live in today. Unfortunately, they will have to deal with the past generations mistakes, from climate change to ozone layer depletion and its consequences such as higher global levels of cancers and other diseases. These generations will need much greater control over their environments than we do today and therefore, much better technology in order to survive.
We need to claim responsibility, even if industries and governments won’t. Can more efficient goods with longer lives be designed? Is the recreational use of these rare materials acceptable? Awareness needs to be raised now if we have any chance of halting the exploitation and expiration, as I for one could not live with the guilt of knowing that in the future a sick child may die due to a lack of MRI scanners all because we wasted the helium needed to cool these machines in our party balloons!

Maybe creating an army of mini Eco Warriors can help?

Image by Art Revolution
The picture says it all, we talk so much about leaving a better planet to our kids, that we forget about leaving better kids to this planet. With our climate recently becoming more and more unstable, there seems to be a lot of concern and general talk about the environment. Phrases like ‘global warming’ and ‘sustainable resources’ are appearing more frequently in the media, so much so that we no longer take much notice of these articles.
Should we really be paying more attention to these issues though? Becoming desensitised to these common phrases isn’t going to make the problem go away now and it never will. It is our responsibility, whether we wish to acknowledge that fact or not, that this is our planet and what happens to it and its vital resources is down to us. But what can we actually do?
Reduce, reuse, recycle? Yet another common phrase often recited in response to questions about protecting the environment, which has lost its meaning for a lot of us. What about education as an answer? Education never seems to be brought up in relation to protecting our planet. We only end up learning about environmental issues when we already have bad habits in our daily lives. Driving to the shop that’s less than a mile walk away, throwing out plastic bags instead of reusing them or bringing your own bag shopping, leaving the tap running when brushing your teeth or washing up after dinner and buying way too much food in the weekly shopping, thinking that you’ll eat it all. Sound familiar? We all do it. We get to this age, living on this planet, using its resources without care like they’re never going to run out, purely because we have never had cause to worry before and because we didn’t know the bad effects our behaviour can have on the environment. It’s not down to ignorance that a lot of us young people have such environmentally unfriendly habits; it’s down to a lack of proper education around the topic.
Maybe if we had been better educated about the environment and its decreasing resources from when we were little, we would have different habits and different views now, at this age. It wouldn’t be a case of having to try and change how we live; more that we grew up being contentious, saving resources and trying to protect and appreciate the environment around us. I don’t mean to try and turn kids into mini eco warriors; I mean to better educate them earlier about what’s actually going on in the environment. What are the resources we need to be worrying about? Which resources are running out and what are the more sustainable options? Maybe try and make things like recycling and water conservation normal everyday things rather than a bonus, which is how they’re seen now.
Maybe if parents stopped worrying about infections and cuts and bruises and threw their kids outside during the summer to enjoy nature and have fun outdoors rather than letting them stay stuck inside playing with plastic toys and expensive electronics which are causing even more damage to the environment. Maybe if nature actually meant more to us from when we were little, we would be more bothered about getting out and doing something about environmental issues rather than sitting inside reading about and talking about global warming and sustainable resources on our smartphones and laptops.

Today is Earth Day

It’s hard to believe that it has come around again…another 12 months and for many of us not a lot has changed…or has it?  More and more people at taking personal and community action to do something about reducing carbon emissions  and increasing biocapacity… so let’s join the other 1 billion people who are doing something and start to deal with global warming. Link to Earthday.org or their blog.

This year everyone is invited to download a photo  to help  personalize the massive challenge climate change. They say every picture tells a story…what does yours say about how has climate change impacted you? Or what are you doing to be part of the solution?

The Real Cost of a Google Search!


Can Google go Green? 

Google searching has become a basic tool in everyday life. If you don’t know the answer, just Google it! Since its launch in 1997, billions of people worldwide have been using it. It’s a free search engine which I’m pretty sure most people use on a daily basis. For us it’s free to use, but what is the real cost of a Google Search? There are many factors that need to be taken into account, such as the amount of carbon dioxide emitted not only from generating the search results, but the emissions from our electronic devices while we are searching.
A typical Google search takes on average about 0.2 seconds to return results. That Google search is equivalent to about 0.2 grams of CO2. [1] It seems to be a small enough figure. But in 2011, Google handled about 1,722,071,000,000 searches! [2] That amounts to roughly 350 thousand tonnes of CO2 emissions that year! But who owns that carbon emission? Us or Google? We’re the ones using the search engine, but Google’s the one that’s returning the results. Google has gone green and offset their carbon emissions to deal with their environmental impact. We too should aim to reduce our carbon emissions.
That was just the carbon dioxide emission cost of the actual Google search, the cost of running the device that the search is done on has not been taken into account yet! According to a Harvard University physicist, a typical search on a desktop computer generates about 7 grams of CO2. [3] This is taking into account the CO2 emissions generated from both the Google search and the desktop computer. So really that amounts to about 12 million tonnes of CO2 emissions for the year 2011 just for Google searches!
In doing this blog alone, I have already done three Google searches. One for finding out the actual cost of a Google search, another for how many searches Google handled in one year and finally another for getting an image for this blog. So I have already generated 21 grams of CO2 just by searching for information for this blog. This does not include the time I spent using the computer to type this blog up and emailing it!
So how can we reduce our Google search carbon emissions? Instead of making unnecessary searches, we should think about what we really need to look up. In fact, we can reduce our overall carbon emissions by using sustainable renewable sources of energy, such as wind and sunlight. If our electronics are powered by renewable energy, we have already immensely reduced our CO2­ emissions.

Bill Gates on Zero Carbon Energy

Bill Gates presents an interesting TED talk about the need to develop alternative energy sources to develop Zero carbon emissions globally by 2050.  The thing that comes over for me is the need to set a realistic and fixed price for carbon emissions to stimulate the type of research that we need right now.

Review: Fundamentals of Sustainable Development by Niko Roorda


There is an ever increasingly large number  of books on the market dealing with sustainable development, so any new book has to offer something new.  Fundamentals of Sustainable Development By Niko Roorda published under the  Earthscan imprint by Routledge (2012) offers just that in a very innovative way.  It goes against the trend of specialization within the area of sustainable development, which often creates inaccessible and  to my mind overly confusingly complex views, but gives a fresh approach to understanding the problems and to some extent the solutions to the crisis facing us today. Roorda describes the crisis in the develop world as the triple crunch  (i.e. climate change, economic crisis and oil depletion), which illustrates his no nonsense approach.

The book is broken down into two parts. Part I is called SWOT analysis (i.e. strengths, weaknesses, opportunities and threats) which explores the global situation. This is made up of four chapters: 1. Sustainable development: an introduction; 2.  Flaws in the fabric: people and nature; 3. Flaws in the fabric: people and society,; and 4. Sources of vigour, this later chapter dealing with global strengths.  Part II is Solution Strategies and  explores some of the ways in which sustainability can be achieved through a further four chapters : 5. Here and there; 6. Now and later; 7. Climate and energy; and 8. Sustainable business practices.  Based on case studies and littered with other examples and colour images  this is a fascinating book  and is as complete a text as I think could have been achieved.  It has numerous student questions which, with the support of an equally innovative and exciting website (www.routledge.com/cw/roorda), makes this text very interactive.

The book really is interdisciplinary, and while challenging in places is truly accessible to readers of all backgrounds.   The presentation of the book is excellent and the format makes this a very attractive paperback, and at 350 pages, it is not too big for students (and lecturers) to carry around. This is a colourful and intriguing textbook which I highly recommend.  It is the sort of book you wish you had written yourself, but Niko Roorda has done just that and in the process added a remarkable edition to the sustainability library.

Waste Storage Efficiency


I feel that improvement should be given on the recycling of household plastic and metal materials such as bottles, cans, etc. A problem with storing these materials for appropriate recycling is that they take up a lot of space in the home if not compressed properly, thus the containers they are kept in can overflow very easily, which not only discourages people from maintaining them for recycling, but also, for many, results in frequent visits to the recycling units.

Compression of recyclable material would allow more to be stored efficiently

However, if households were to contain a small yet strong compressor for these materials in order to flatten them completely, more of them can be stored between recycles. The amount of carbon emissions which would go into making these handy compressors would thus be returned by the increase in waste material recycled appropriately and the reduction of recycling trips required. This means that excess material would no longer have to be inappropriately discarded until enough space has been freed-up to dispose of them properly.
