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 na├»ve? 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.

Real time wildfire mapping in the United States

Although we are all watching the current wildfires in California, a more serious situation is occurring in Alaska with thousands of hectares currently affected. 

The Geospatial Multi-Agency Co-ordination Group provides real time mapping of current wildfires throughout the United States.  Zoom onto the flame showing a wildfire for its perimeter and then click for full details of the size of the fire, exact location and the extent to which it has grown or shrunk over the past 24 hours and also details of how much has been contained.  With high temperatures and less rainfall this is the worst season for wildfires to date.

U.S. Ecological Deficit Day

Today is US Ecological Deficit Day...for those of you who know all about ecological footprints then you know that we in the developed world are all guilty of exceeding our personal one planet allowance.  Today is the day  when the US exceeds its national biocapacity and goes into the red (i.e. deficit). Each year it gets earlier and today is that point in the Nation's ecological footprint balance.  More information.  Should every country adopt an Ecological Deficit Day...you bet they should!

Trash is for Tossers: say NO to trash

‘Trash is for Tossers (say NO to trash)’ is the blog of  Lauren Singer who is trying to live a zero waste life in the heart of New York City.  She is sharing her journey towards this excellent goal, although I suspect it is going to be a tough one. She has one great quote ‘I really decided that I not only needed to claim to love the environment, but actually live like I love the environment’.  She also gives two really interesting and helpful definitions:

Waste …’a  point source, meaning it is discarded by its holder with intent of it going to landfill. Trash is anything a person plans to throw away or anything a person deems obsolete that is then discarded in a manner where it will not be intended for re-purposing or reuse even if it unknowingly will be at some point in the future. ‘

Zero Waste means that I do not produce any garbage. No sending anything to landfill, no throwing anything in a trash can, nothing. However, I do recycle and I do compost. 

Lauren is really on the right path here and I for one will be following her journey and learn from her experiences.
